Analog inputs

Section 3 Analog inputs D0E3188T201305151403 v1

3.1 Introduction D0E3189T201305151403 v1

Analog input channels in the IED must be set properly in order to ensure correct
controlled switching operations. The directions of the input currents must be
defined in order to reflect the way the current transformers are installed/connected
in the field (primary and secondary connections). Control and monitoring
algorithms in the IED use primary system quantities. Consequently, the setting
values are expressed in primary quantities as well and therefore it is important to
set the transformation ratio of the connected current transformers and voltage
transformers properly.

The availability of CT and VT inputs, as well as setting parameters are fixed for
Switchsync PWC600.

The IED has the ability to receive sampled voltage and current values from one or
more (up to 4) merging units (MUs) via IEC 61850-9-2(LE) process bus. Mixed
mode is possible, for example, conventional voltage transformers and electronic
current sensors via MU, or vice versa.

A reference PhaseAngleRef must be defined to facilitate service values reading.

This analog channels phase angle will always be fixed to zero degrees and all other
angle information will be shown in relation to this analog input. By default,
PhaseAngleRef is assigned to TRM - Channel 5, which is used for the first
reference voltage input (Source voltage L1) in the pre-configuration. If source
voltage from TRM is not available (not connected), SST would next select TRM -
Channel1 (Load current), MU1-L1U (Source voltage 9-2 LE) and MU1-L1I (Load
current 9-2 LE). During testing and commissioning of the IED, the reference
channel can be changed to facilitate testing and service values reading.

3.2 Operation principle D0E3192T201305151403 v1

The direction of a current depends on the connection of the CT. The main CTs are
typically star connected and can be connected with the star point towards the object
or away from the object. This information must be set in the IED.

The convention of the directionality is defined as follows:

25
Technical Manual
Section 3 1MRK 511 275-UEN A
Analog inputs

• Positive value of current or power means that the quantity has the direction
into the object.
• Negative value of current or power means that the quantity has the direction
out from the object.

For directional functions the directional conventions are defined as follows (see
Figure 1).

• Forward means the direction is into the object.

• Reverse means the direction is out from the object.

Figure 1: Internal convention of the directionality in the IED

If the settings of the primary CT is correct, that is CTStarPoint set as FromObject

or ToObject according to the plant condition, then a positive quantity always flows
towards the protected object, and a Forward direction always looks towards the
protected object.

The settings of the IED are given in primary values. The ratios of the main CTs and
VTs are therefore basic data for the IED. The user has to set the rated secondary
and primary currents and voltages of the CTs and VTs to provide the IED with their
rated ratios.

The CT and VT ratings are entered in SST, under the Reference signals milestone.
Channel names are assigned in the pre-configuration. Manual changes can be done
under Main menu/Hardware/Analog modules in the Parameter Settings tool or
on the LHMI or WHMI.

Section 4 Binary inputs and outputs

4.1 Binary inputs

GUID-96B8BB9C-7C3D-48D9-95FB-A2E5C6377C21 v1

A binary input mirrors the status (on/off) of an electrical DC signal and reports
every status change with time stamp.

The BIO module provides 9 optically isolated binary inputs. Some of them share a
common negative terminal; see the connection diagram for details.

The PIO module provides 12 optically isolated precision binary inputs with time
stamp accuracy of 100 microseconds.

All binary inputs are equipped with digital filters, to eliminate bouncing and
oscillations on the input signals.

4.1.1 Debounce filter D0E3037T201305151403 v1

The debounce filter eliminates bounces and short disturbances on a binary input.

A time counter is used for filtering. The time counter is increased once in a
millisecond when a binary input is high, or decreased when a binary input is low. A
debounced status change is forwarded when the time counter reaches the set
DebounceTime value and the debounced input value is high, or when the time
counter reaches 0 and the debounced input value is low. The default setting of
DebounceTime is 5 ms.

A binary input ON-event is assigned the time stamp of the first rising edge after
which the counter does not reach 0 again. The same applies when the signal goes
down to 0 again.

Each binary input has a filter time parameter DebounceTimex, where x is the
number of the binary input of the module in question (for example
DebounceTime1). For precision binary inputs, the debounce time can be specified
separately for On and Off status changes.

The debounce time should be set to the same value for all channels
on the board.

Binary inputs and outputs

4.1.2 Oscillation filter D0E3034T201305151403 v1

Binary input wiring can be very long in substations and there are electromagnetic
fields from for example nearby breakers. An oscillation filter is used to reduce the
disturbance from the system when a binary input starts oscillating.

Each debounced change of input status increments an oscillation counter.

Periodically (every OscillationTime), the oscillation counter is checked and reset. If
the counter value before reset is above the set OscillationCount value the signal is
declared as oscillating and not valid. If the value is below the set OscillationCount
value, the signal is declared as valid. During counting of the oscillation time the
status of the signal remains unchanged, leading to a fixed delay in the status
update, even if the signal has attained normal status again.

Each binary input has an oscillation count parameter OscillationCountx and an

oscillation time parameter OscillationTimex, where x is the number of the binary
input of the module in question. For precision binary inputs, the filter parameters
can be specified separately for On and Off status changes.

4.2 Binary outputs

4.2.1 Binary outputs GUID-5E9466BB-B479-4CDF-9FAD-7D0C6E2D0789 v1

The PSM02 or PSM03 module provides 10 output relay contacts. 6 of these are
rated for making and carrying high currents, and three of them include circuits for
trip coil supervision. The remaining 4 relay contacts are intended for signaling; one
of them is internally hardwired to indicate Internal Relay Failure (IRF).

The BIO module provides 9 output relay contacts. Out of these, 3 are rated for
making and carrying high currents. The remaining 6 contacts are intended for
signaling; some of them share a common terminal, see the connection diagram for
details.

The PIO module provides 6 fast static outputs that are rated for making and
carrying high currents. The switching instants of these precision binary outputs can
be controlled at 100 microseconds’ accuracy, which makes them ideal for
controlled switching of circuit breakers.

Binary outputs rated for making and carrying high currents allow connection
directly to breaker tripping and closing coils. If breaking capability is required to
manage failure of the breaker auxiliary contacts normally breaking the coil current,
parallel reinforcement by an external relay is required.

5.4 Status LEDs D0E5632T201305151403 v1

There are three status LEDs on the LHMI, above the LCD screen: Ready (green),
Start (yellow), Trip (red).

The green LED has a fixed function that present the healthy status of the IED. The
yellow and red LEDs are user configured. The yellow LED can be used to indicate
that a disturbance report is triggered (steady) or that the IED is in test mode
(flashing). The red LED can be used to indicate a operation command.

The yellow and red status LEDs are configured in the disturbance recorder
function, DRPRDRE, by connecting a start or trip signal from the actual function
to a BxRBDR binary input function block in PCM600 and configuring the
SetLEDn setting to Off, Start or Trip for that particular signal.

The function blocks LEDGEN and GRP1_LEDx, GRP2_LEDx and GRP3_LEDx

(x=1-15) control, and supply information about the status of the indication LEDs.
Input and output signals of the function blocks are configured with PCM600. The
input signal for each LED is selected individually using SMT or ACT. Each LED is
controlled by a GRP1_LEDx function block, which determines the color and the
operating mode.

By applying logical 1 to one of the inputs, a LED is activated in the corresponding

color. In case more than one input is active at the same time, red has highest
priority, followed by yellow and green.

Each indication LED on local HMI can be set individually to operate in 6 different
sequences; two as follow type and four as latch type. Two of the latching sequence
types are intended to be used as a protection indication system, either in collecting
or restarting mode, with reset functionality. The other two are intended to be used
as signalling system in collecting mode with acknowledgment functionality.

5.5.6 Operation principle

5.5.6.1 Operating modes D0E5634T201305151403 v1

Collecting mode

LEDs that are used in collecting mode of operation are accumulated (latched on)
continuously until the unit is acknowledged manually. This mode is suitable when
the LEDs are used as a simplified alarm system.

Re-starting mode

In the re-starting mode of operation each new start resets all previous active LEDs
and activates only those, which appear during one disturbance. Only LEDs defined
for re-starting mode with the latched sequence type 6 (LatchedReset-S) will initiate
a reset and a restart at a new disturbance. A disturbance is defined to end a settable
time after the reset of the activated input signals or when the maximum time limit
has elapsed.

5.5.6.2 Acknowledgment/reset D0E5635T201305151403 v1

From local HMI

Active indications can be acknowledged/reset manually. Manual acknowledgment
and manual reset have the same meaning and refer to a common signal for all the
operating sequences and LEDs. The function is positive edge triggered, not level
triggered. Acknowledgment/reset is performed via the button and menus on
the LHMI.

46
Technical Manual
1MRK 511 275-UEN A Section 5
Local HMI

From function input

Active indications can also be acknowledged/reset from the RESET input to the
LEDGEN function. This input can for example be configured to a binary input
operated from an external push button. The function is positive edge triggered, not
level triggered. This means that even if the button is continuously pressed, the
acknowledgment/reset only affects indications active at the moment when the
button is first pressed.

Automatic reset
Automatic reset can only be performed for indications defined to operate in re-
starting mode with latched sequence type 6 (LatchedReset-S). When automatic
reset of the LEDs has been performed, still persisting indications will be indicated
with a steady light.

5.5.6.3 Operating sequence D0E5638T201305151403 v1

The sequences can be of type Follow or Latched. For the Follow type the LED
follow the input signal continuously. For the Latched type the LED is switched ON
whenever the corresponding input signal is activated, and remains ON until the
active indications are reset.

The figures below show the function of available sequences selectable for each
LED separately. For sequence 1 and 2 Follow type, the acknowledgment/reset
function is not applicable. Sequence 3 and 4 Latched type with acknowledgement
are only working in collecting mode. Sequence 5 is working according to Latched
type and collecting mode while Sequence 6 is working according to Latched type
and re-starting mode. The letters S and F in the sequence names have the meaning
S = Steady and F = Flash.

Upon activation of the input signal, LED is switched ON in the color corresponding
to the activated input and operates according to the selected sequence diagrams
below.

In the sequence diagrams the LEDs have the following characteristics:

= No indication = Steady light = Flash

G= Green Y= Yellow R= Red

Sequence 1 (Follow-S) D0E5419T201305151403 v1

This sequence follows all the time, with a steady light, the corresponding input
signals. It does not react to acknowledgment or reset. Every LED is independent of
the other LEDs in its operation.

the indication starts flashing. After acknowledgment the indication disappears if
the signal is not present any more. If the signal is still present after
acknowledgment it gets a steady light.

difference to sequence 3 and 4 is that indications that are still activated will not be
affected by the reset that is, immediately after the positive edge of the reset has
been executed a new reading and storing of active signals is performed. Every LED

automatically reset at a new disturbance when activating any input signal for other
LEDs set to Sequence 6 LatchedReset-S. Also in this case indications that are still
activated will not be affected by manual reset, that is, immediately after the

Each output on the FNKEYMD1 - FNKEYMD5 function blocks can be controlled

from the LHMI function keys. When used in operation mode (Type setting)
‘Control’, pressing a function key controls the output signal of the respective
function block. These binary outputs can in turn be used to control other function
blocks, for example, switch control blocks, binary I/O outputs etc.

FNKEYMD1 - FNKEYMD5 function block also has a number of settings and

parameters that govern its behavior. These settings and parameters are normally
defined in the pre-configuration and can be modified by using the PST.

7.1 Introduction GUID-7B9D8386-0CCA-4AB9-92E3-DE05405A0405 v1

The function blocks described in this section are at the core of the controlled
switching functionality. These function blocks have strong interdependency and are
combined in this section to explain the concept and the functional interactions.

Controlled switching is not a category of function blocks in

PCM600 and LHMI.

Controlled switching (also known as point-on-wave switching or synchronous

switching) is defined as controlling the circuit breaker in such a manner that the
instant of current inception (on closing) or contact separation (on opening) occurs
at an instant that is optimal for the circuit breaker, the load, and/or power quality.
This section explains the operation principle from the product user’s view point.

The involved function blocks are listed in Table 21.

A Switchsync PWC600 IED controls the instants at which the circuit breaker
operates, monitors the switching operation and logs the monitored data. To achieve
this, various function blocks perform specific functionalities. SSCPOW sets the
switching target and controls the CB accordingly, ACBMSCBR monitors the
switching and determines the correction(s) required, and MONCOMP assists in
logging the data.

7.2 Operation principle GUID-87EB84D8-3AC2-466B-A323-FBB5FB9477D6 v1

A random instant of switching the circuit breaker might impact the load, power
system or circuit breaker contacts because of high voltage or current transients or
re-ignitions/re-strikes in the CB. Conversely, controlled switching of the circuit
breaker, and hence, the power system equipment can avoid harmful transients in
the network and also increase the life time of the circuit breaker and/or the
switched load.

Figure 26 shows an ideal circuit breaker closing on a grounded single phase

reactive load. Considering no energy stored on reactor time, at the instant when CB
is operated, the source voltage wave shown in the figure will appear across the
circuit breaker contacts until the circuit breaker closes electrically. If a command is
given at any random instant trsc to the circuit breaker, the circuit breaker will close
electrically at trsi and mechanically after the circuit breaker operating time TCB.
However, the random point on wave Drsi at which this switching happens might
create undesirable transients. In such circumstances, it is recommended to optimize
the switching targets based on the design and connection configuration of
connected load that need to be switched. A point-on-wave controller such as
PWC600 analyzes the reference voltage signal and identifies a favorable switching
target (Dosi, at time tosi) for the reactive load. Now the controller delays the
command by TCTD = tosi – trsi (controller time delay) and releases it to circuit
breaker at tosc. This will result into making of the current at instant tosi considering
the circuit breaker closing time of TCB.

Drsi = point on wave for random switching

After releasing the switching command, the controller monitors the switching
operation to evaluate various electrical and mechanical parameters of CB, like
electrical operating time, mechanical operating time etc. These monitored
parameters are used for assessing the success of the performed operation and the
health of the circuit breaker, as well as for adapting the operating parameters for

subsequent operations so as to achieve optimal point-on-wave performance. Key

parameters will also be logged for future analysis.

Actual switching operations can be monitored by analyzing the precision

mechanical status feedback contacts (precision auxiliary contacts) and/or the
primary current or load voltage signals. Figure 27 and Figure 28 shows the single

work in a close coordination. Figure 29 shows the interconnection between these
functions. Control functionality is mainly handled by SSCPOW function.

The main functionalities can be categorized into:

1. Control
2. Monitoring
3. Data acquisition

7.2.2 Control GUID-F45F7CE6-622A-4A1C-8373-BC80CACB6992 v1

Control (Switching target evaluation and command handling) is mainly handled by

SSCPOW. It supports two modes of operation:
• Normal switching mode
• CB learning mode

7.2.2.1 Normal switching mode GUID-C902E2A8-DD28-4A1C-9C16-600962A925ED v1

The primary objective of Switchsync PWC600 is to energize or de-energize loads

at optimal points on wave to minimize switching transients and prevent re-ignitions
or re-strikes. In normal switching mode, SSCPOW function achieves this primary
objective.

Reference signals GUID-A172C8FD-8642-4331-99DF-A4B2F85E1585 v1

To perform a controlled switching, the function requires a valid reference signal

against which the optimal point on wave control has to be achieved. The reference
signal for closing operations is always source voltage. The reference for opening
operations can be selected by setting OpenRefI as either source voltage or load
current, as shown in Table 22.

UConn Type Setting SSCPOW Specifies the connection type of the source voltage
transformer. It can be selected as

• One phase star — Either of the phase to ground

voltage signal is available
• Three phase star — All the phase to ground voltage
signals are available
• One phase delta — Either of the phase to phase
voltage signal is available
• Three phase delta — All the phase to phase voltage
signals are available

UConnPh Setting SSCPOW When UConnType is selected as “One phase star” or

“One phase delta”, the actually connected phase or
phase to phase information has to be specified here from
the options

• L1/L1-L2
• L2/L2-L3
• L3/L3-L1

Selection in this setting is irrelevant if Three phase star or

Three phase delta are selected for UConnType setting.

When only one phase voltage is available, the setting UConnPh is used to specify
the phase information that is connected. L1/L1-L2 when selected means that L1
phase is connected if selection in UConnType is One phase star, or L1-L2 voltage is
connected if selection in UConnType is One phase delta. The same is applicable for
L2/L2-L3 and L3/L3-L1.

When One phase star or One phase delta is being used, that voltage
signal shall always be connected to the L1 voltage input of the IED
irrespective of the phase/phases being connected in real filed to the
voltage transformer.

The input interfaces to connect voltage and current signals are described in Table
24.

For any reference source, the frequency and point-on-wave targets are ascertained
by tracking the signal for a number of half cycles. This can be configured using the
NumOfHalfCycle setting as described in Table 25. Higher values of
NumOfHalfCycle are used to provide more stable tracking. Conversely, if the
system frequency is expected to change rapidly, a lower value of NumOfHalfCycle
can be provided. Moreover in case of rapid changes in frequency, the low value of
the parameter may lead to inaccurate targeting.

Point-on-wave switching is not suggested to be used on rapidly

changing system conditions.

Half cyclic algorithm for Frequency tracking: At every execution cycle the
functions (SSCPOW & ACBMSCBR) check the latest 20 samples @ 80 samples /
cycle, for change in polarity (from positive to negative or vice versa), between 2
consecutive samples. Using linear interpolation, the time stamp of exact zero
crossing point will be calculated between the 2 samples of opposite polarity, and
stored in a list (Cyclic) of zero crossings. The same procedure will be repeated for
2*NumOfHalfCycle execution cycles, appending every zero crossing time stamp to
the list. Upon completion of checking the set number of half cycles the average of
stored zero crossing time stamp data will give the approximated time between zero
crossings as well as actual system frequency, which will be further used for point-
on-wave switching operations.

Any selected reference signal is validated to be healthy before being used. If the
reference signal cannot be used, reference missing condition is declared and
switching will either be bypassed or blocked according to the ContingencyMode
setting (see below). The healthiness of a reference signal is ascertained by
comparing its RMS magnitude against a configurable threshold called the dead
value setting. If the RMS magnitude of the signal is lower than the threshold, the
signal cannot be used as a reference. Separate settings are available to check the
healthiness of source voltage and load current as reference.

67
Technical Manual
Section 7 1MRK 511 275-UEN A
Controlled Switching and Monitoring

For a three-phase reference signal, the healthiness of each phase is checked

individually. Only if all phases are found healthy then the entire reference signal is
declared healthy.

SSCPOW expects that UBase and IBase in GBASVAL (selected by

GlobalBaseSel) are set as rated phase-to-ground voltage and
maximum steady-state current into the load, respectively. For
controlled switching of transformers, transmission lines, or cables,
the steady-state current shall be given as the nominal charging
current with no further load connected.

The conditions for using the available reference signal and for declaring missing
reference are summarized in Table 27 below.

Handling of switching commands GUID-48CEA456-E1C7-4370-8A6F-A4F50572B9F9 v1

SSCPOW reacts to switching commands received on the inputs described in Table

29. There are two inputs for initiating a CB opening operation and two inputs for
initiating a CB closing operation. In case commands are received on both the inputs
(for example, when the application is configured to receive commands from binary
inputs and GOOSE interfaces in parallel), the command that has been received
earlier will be executed and the other one is ignored. When a switching command
has been accepted, no further commands are accepted until the function completes
the earlier command by logging the data.

The specific reaction to a received command is controlled by different settings and

to the CB. Bypass means that the CB will be operated without point-on-wave
control.

BLKOPL2 / BLKOPL3, BLKCLL1 / BLKCLL2 / BLKCLL3, OPBYPASS or

temporary, for example, because of loss of reference signal etc., they are generated
for as long as the condition persists, minimum one execution cycle. The outputs are

For controlled switching operations, SSCPOW will delay the release of the output
commands to the three phases of the circuit breaker to achieve a point on wave
switching that is desirable for the selected application. Minimum controller delay is
one power cycle and depends on operating time and switching angle.

All output commands are issued on three individual outputs for opening and three
outputs for closing operations. These output signals include time stamp information
to switch on the IED’s static outputs on the PIO card at the specified times. The
outputs are described in Table 32.

The STRDPOW output indicates the controlled switching status, that is, a valid
operation command (Close or Open) was received and the command is for
controlled operation of the breaker. STRDPOW will not be set if a bypass
command was received. The output is set to high immediately after detecting a
valid controlled operation command, and reset when the last control output is
switched off at the end of the operation.

SSCPOW function can be configured to automatically execute a preset switching

strategy based on application information, or to switch at user defined targets.
LoadType setting allows the user to do this selection between a choice of
predefined loads or user defined setting. If user defined load is selected, the user

Target selection for closing operations GUID-DFA06B61-ECF2-4796-A802-FD90105F6D3E v1

For controlled closing operations, SSCPOW chooses the ideal switching strategy
depending on load and system configuration defined in section Application
selection.

The selection of the target phase angles for energization (also referred as making
targets) depends on the basic capacitive or reactive nature of the load. Capacitive
loads need to be energized at voltage zero across the circuit breaker. This switching
strategy ensures low inrush currents and low transient voltages. Refer to Equation 1
for relation of voltage across the capacitive load and current through it. If the
switching happens at zero voltage, the instantaneous current drawn will be
marginal.

Similarly, in case of 3-limb cores for transformers or reactors or a transformer with

secondary/tertiary delta connection, charging of one phase induces voltage in other
phases. Making targets are appropriately modified to optimize the switching
angles.

Whenever a Power transformer is being energized from star

grounded side and at least one of its secondary or tertiary winding
is delta connected, the application should be selected as Coupled
transformer.

The above mentioned targets are ideal point-on-wave angles at which load
energization (current inception) should occur. However, for a practical circuit
breaker, the primary contacts close with a certain velocity and thereby reducing the
gap between the contacts with time. At any point of time, if the gap’s dielectric
strength is less than the instantaneous voltage appearing across the contacts, the
dielectric breaks down and a pre-strike happens, thereby energizing the load
through an electrical arc. For practical purposes, the rate of decay of dielectric
strength (RDDS) is assumed constant, see Figure 32.

Further factors that affect the actual command release are the uncertainty
(statistical scatter) in mechanical operating times, RDDS of the circuit breaker,
degradation in dielectric strength and operating characteristics. Modern circuit
breakers have been designed for stable operating times. However, even slight
deviations from the optimal energization instant can result in higher electrical
stress, depending on whether the actual switching time is shortened or elongated.
Figure 34 shows this for a capacitive application, where the effect of scatter is more

From Figure 34, it is evident that, given symmetrical scatter, V” is significantly

higher than V’. Therefore, the target instant of mechanical contact touch is delayed
such that current inception would ideally occur at Dosi, to minimize the highest pre-
strike voltage on either side. This is illustrated in Figure 35. For capacitive loads,
the actual switching point is delayed from optimal switching point.

Figure 36: Shifting of mechanical target switching instant to compensate the

influence of mechanical scatter

The statistical scatter of the mechanical operating times and of the RDDS is
considered specific for each circuit breaker type. Furthermore, certain
environmental and operating conditions like temperature of the drive, control
voltage of the operating mechanism, idle time of the circuit breaker, drive pressure
etc. may impact the operating times. For every circuit breaker type, tests can be
conducted to know the dependence of operating times on each of these parameters,
as described in IEC 62271-302. If this information is made available, compensation
of scatter and other influences as defined above can be directly applied. The
amount of correction to be provided is calculated by the ACBMSCBR and
CBCOMP function blocks. ACBMSCBR calculates the correction related to scatter
in RDDS, T6. In addition to the static correction, ACBMSCBR also evaluates the
dynamic correction required because of changes in system voltage and frequency.
When information is made available and compensation is enabled, CBCOMP
function evaluates the correction value T2 that is attributable to environmental
parameters like control voltage, drive pressure, drive temperature etc. Up to two
additional compensation characteristics can also be configured by the user based on
the application requirements. SSCPOW takes the information from these two
functions and calculates the overall correction to be applied.

Apart from the factors described above, the circuit breaker making time can vary
with time, for example, because of ageing. ACBMSCBR monitors every operation
to identify the amount of deviation of the actual making instant from the target
making instant. A fraction β of the deviation is compensated for the next operations
to ensure that the target converges to the optimum target instant. This functionality
enables adaptive correction independently for both electrical and mechanical
errors. Equation 5 gives the calculation of adaptive correction.

Where,

electrical error = Difference between target making instant and actual current

For calculating the predicted operating time for the next operation, the new
correction value is added to the predicted operating time of the last operation.

New predicted operating,

Tnew = Told + T3

IECEQUATION17085 V1 EN-US (Equation 6)

Applying only electrical or mechanical adaptation will still

influence both the electrical and mechanical targets because of the
influence of prestrike characteristics of the circuit breaker. Setting
βelec or βmech as zero ensures that the corresponding electrical error
or mechanical error are not being used for adaptive correction.

The primary contact’s closing instant is obtained from the timing information of
NO (52a) and NC (52b) auxiliary contacts, when available, based on the contact
displacement settings. It is sufficient to have only one auxiliary contact information
to estimate the primary contact timing. However, the information is more reliable
and accurate if NO (52a) contact information is available and further more accurate
if both the auxiliary contact information is made available. The mechanical
operating time is calculated as per Equation 7.

Target selection for opening operations GUID-FEDBC10F-1961-49DA-A15B-BFFA4D97A180 v1

For controlled opening operations, SSCPOW chooses the ideal switching strategy
depending on load and system configuration defined in section Application
selection.

The selection of the target phase angles for de-energization (also referred as
interrupting targets) depends on the basic capacitive or reactive nature of the load.
Capacitive loads need to be de-energized such that by the time the current is
interrupted at its natural zero, the circuit breaker contacts have separated
sufficiently far for the dielectric strength of the contact gap to exceed the voltage
appearing across it. This switching strategy ensures that the capacitive load doesn’t
restrike.

86
Technical Manual
1MRK 511 275-UEN A Section 7
Controlled Switching and Monitoring

Figure 37 shows the CB primary contacts opening at time topen. The current
continues to flow till its natural current zero (tint). Restrike can be avoided if the
circuit breaker regains its dielectric strength after current interruption such that it is
always greater than the voltage appearing across it.

For de-energizing capacitive loads, the arcing time (Tarc = tint – topen) is considered
such that it allows the circuit breaker to gain as much dielectric strength as possible
by the time of interruption, subject to the condition that mechanical scatter doesn’t
shift topen beyond the preceding current zero crossing.

Figure 37: Capacitive load de-energization

Inductive loads, upon interruption of current, create high-frequency Transient

Recovery Voltages (TRV). Similar to the case of de-energization of capacitive
loads, the circuit breaker should have gained sufficient dielectric strength to avoid
re-ignitions after current interruption.

Figure 38: Reactor de-energization

From inductive switching type tests, the re-ignition free window of a circuit
breaker can be deduced for the specific circuit. Re-ignition free window is defined
as the range of arcing times wherein the circuit breaker doesn’t re-ignite. Providing
high arcing times can increase the current chopping thus creating higher TRV.
Providing low arcing times can help in reducing the TRV but the circuit breaker
might not gain sufficient dielectric strength. By default, PWC600 applies a
compromise strategy of opening the primary contacts in the middle of the re-
ignition free window defined for the specific circuit breaker model.

In case of a transformer, the charging current is usually so small that a modern

circuit-breaker will extinguish it by chopping within a very short time, usually not
exceeding a millisecond.

Table 47 defines the settings specifying the minimum and maximum arcing times
required for reactive loads. The same settings are also used for capacitive loads.
For transformer, the arcing time information is provided by a separate setting.

Where k is the impedance ratio, calculated as per Equation 9.

The above mentioned targets are optimal phase angles at which load de-
energization (current interruption) should occur. However, for a practical circuit
breaker, the primary contacts open with a certain velocity and thereby increasing
the gap between the contacts with time. As explained above, the contacts should be
opened such as to interrupt the current at the times specified in Table 48 to Table
51. SSCPOW function hence considers the arcing times as specified in Table 47 to
release the commands as shown in Equation 10.

Where,

tasc = Target command release time (output to circuit breaker)

equal to the ArcTimeTrafo setting. For all other loads the arcing time will be as
mentioned above in Table 49 through Table 53.

information

TCTD = Controller time delay for achieving contact separation of an ideal breaker at
the target interruption instant

As current will usually flow until a natural zero during CB opening, it is not
possible to deduce the actual instant of primary contact separation from the primary
voltage and current signals. Thus, no direct adaptive correction can be performed.
However, if any re-strike/re-ignition is detected by ACBMSCBR, SSCPOW
increases the target arcing time by 1ms for every detection. The user can limit this
arcing time extension by specifying how much correction is allowed, in the
MaxReStrikeCorr setting. Hence the actual target interruption instant is defined as
given in Equation 11.

tasc = trsc + Tarc + T2 - TCTD + T7

Where T7 is the cumulated arcing time extension.

7.2.2.2 CB timing test (learning) mode GUID-AFF33553-179B-4979-A894-1BBAC51168B7 v1

In CB learning mode, the CBLEARN function evaluates and learns the timing of
the circuit breaker primary and (if connected) auxiliary contacts. The commands to
the three phases are delayed by setting TimeOutAlarmDelay, to allow every pole to
complete its operation before operating the next pole. CBLEARN sends requests to
SSCPOW to operate a specific CB pole. (Generally, L1 pole is operated first
followed by L2 and L3 poles). SSCPOW upon receiving this request, releases the
command to the circuit breaker pole. CBLEARN function receives the command
and feedback information to evaluate the contact timing information.

The contact timing information evaluated by the CBLEARN is communicated to

functions ACBMSCBR and SCCPOW for switching and monitoring purpose.

7.2.3 Monitoring GUID-AA55ADCF-C4E2-4D51-A079-B6E54C7D885D v1

Monitoring is an important aspect of controlled switching for two reasons.

1. It provides the information about the degree of success of each operation

performed.
2. It allows adjusting the targets for subsequent operations, to optimize controlled
switching performance.

Operations monitoring is performed for both mechanical and electrical parameters.

Various information and alarms are generated depending upon the monitored
parameters, as described in the sections "Electrical monitoring" and "Mechanical
monitoring".

7.2.3.1 Electrical monitoring GUID-DA62E815-2587-40C8-86CB-3A61BDC30190 v1

Electrical monitoring of circuit breaker operations can be performed depending

upon the load connected and available feedback signals. Figure 27 and Figure 28
show the options for electrical feedback that can be used. Electrical monitoring is
performed for identifying the prestrike angles (current inception), arcing times
(current interruption), electrical operating times, electrical status, circuit breaker
interrupter wear, target deviation for performing adaptive correction, etc.

Information Description
Current Identification of instant at which current inception has occurred during CB closing
inception operation. This includes evaluating the point-on-wave phase angle with respect to
the reference signal.
Current inception instant is defined as the instant at which the selected monitoring
feedback signal exceeds a fixed percentage of the corresponding base value.
Current Identification of instant at which the load current was finally interrupted during CB
interruption opening operation.
Current interruption instant is defined as the instant at which the selected
monitoring feedback signal finally drops below a fixed percentage of the
corresponding base value.
Arcing time Arcing time is the time between mechanical opening instant and current interruption
instant.
The mechanical opening instant is obtained directly by adding the mechanical
operating time value, received from CBLEARN, to the received trip output
command timestamp from SSCPOW.
As the mechanical opening time is directly received as input from CBLEARN
function, the arcing time calculation is independent of the auxiliary contacts
availability.
Electrical Assumption of the circuit breaker status (open/closed), based on presence or
status absence of the selected feedback signal: If the RMS value is greater than IDead x
IBase or UDead x UBase, respectively, the circuit breaker is declared electrically
closed, otherwise electrically open.
Electrical Defined as the time from command release to the instant of current inception (for
operating time closing operation) or current interruption (for opening operation).
Re-strike/re- Re-strike or re-ignition is declared if re-occurrence of the selected electrical signal
ignition is detected after initial interruption. See explanation below.
Interrupter Cumulated wear (contact ablation, nozzle erosion) of the circuit breaker interrupter,
wear based on interrupted current. See detailed description below.

For transmission line or power cable, electrical monitoring can be performed only if the charging
current RMS is significant that is, greater than the dead current value setting (IDead x IBase) in
ACBMSCBR function. The first 5 operation cycles will be monitored to ascertain if the current is
significant and steady to be used for monitoring purposes. If the current is not steady, current signal
is not used for electrical monitoring even if it is greater than the dead current setting. (Current is
evaluated as steady only if the RMS values after 5 cycles post inception, or just prior to interruption,
have been constant within ±10% for 5 consecutive initial operations. This evaluation is restarted
whenever one of the SSCPOW settings defining the load application is changed).

When the command is received, ACBMSCBR evaluates the target and predicts the
electrical operating time, prestrike angle, and arcing time information as
appropriate for closing or opening operations, and forwards them to the
MONCOMP function block. The same is performed for the actual values acquired
during the operation. After completing the monitoring, MONCOMP calculates the
error information and consolidates data for logging. Different outputs that provide

For every operation, ACBMSCBR function monitors the operation parameters,

forwards the data to operation log through MONCOMP, and provides the electrical
target correction to SSCPOW. For opening operations, perform the additional
calculations to detect the presence of any re-strikes/re-ignitions and provide
correction of target arcing time (if configured).

Figure 42: Re-strike/Re-ignition detection

Following the opening command, the primary contacts separate at instant tcs.
Instantaneously an electrical arc is drawn, which keeps the current flowing in the
circuit until interruption (usually near natural current zero). The time from contact
separation until initial current interruption is called arcing duration or arcing time,
Tarc. If the following current interruption and the dielectric strength of the circuit
breaker does not exceed the recovery voltage across its terminals, the arc will re-
ignite. This breakdown will make the circuit conducting again and current will
flow till the next natural zero crossing. Trs(for single re-strike), Trs1....Trsn(for
multiple re-strike) is the duration for which the current flows due to the re-
strike/re-ignition. Tna is the no-arc duration between initial interruption and re-
strike/re-ignition. Equation 12 defines the monitored arcing time at successful first
interruption. Equation 13 defines the monitored arcing time when (single or
multiple) re-strike/re-ignition was detected.

Resetting of Re-strike/Re-ignition detection GUID-441CC8B3-3FE2-43DF-9BE9-96CE1A0DE688 v1

When re-strikes/re-ignitions are detected and the limit for correction has been
reached, an alarm(MAXRCALLX) is generated. Subsequent controlled opening
operations will use the maximum correction value and no more correction is
allowed. If further re-strikes/re-ignitions are detected, it is advised to either review
the settings or check the circuit breaker.

When the circuit breaker has been attended (example: overhauled,

or interrupter replaced, or insulating gas replaced), it is advised to
review the settings, considering that the maximum allowed restrike
correction is already being applied.

Resetting the maximum restrike correction modifies the allowable

arcing time of the breaker during the open operation.

To modify the settings, either increase the arcing time or the maximum allowed
corrections. In both cases, noted that if the maximum restrike correction is reset,

100

the correction applied comes back to zero. It is suggested to change the settings
accordingly, preferably in the IED through LHMI/WHMI or in PST.

Interrupter wear GUID-19E91A3A-0F01-4EAF-9837-5F5BAE7683E4 v1

In new condition, a circuit breaker is rated for a certain number of mechanical

operations, that is, no interrupting or very low currents. It is also rated for a certain
(low) number of operations interrupting maximum fault current. In between these
extremes, the interrupted current in every Open operation will cause some erosion
of the contacts and/or ablation of the nozzles, until CB has lost its ability to reliably
switch off current. This interrupter wear characteristic is often generated in the
form of a curve such as Figure 43.

A) or 20 interruptions of 63 kA fault current

ACBMSCBR calculates interrupter wear as the equivalent number of mechanical

operations that the circuit breaker has lost after interrupting a specific current. The
algorithm for calculation of interrupter wear works in several steps. For every CB
open operation,
1. The samples xi of interrupted current are numerically integrated to yield a
value Y,

where n is the breaker type specific exponent (setting CumCurrPower, default

value n = 2) and k is the total number of arcing current samples. Summation
starts at the estimated instant of contact separation and ends at the time of final
current interruption (including additional periods of current flow due to re-
ignition or re-strike).
2. The nth root of integrated current Y is categorized against two threshold values,
MinCurrentLimit and OvercurrentLimit x IBase. MinCurrentLimit is defined as
the minimum current interrupted up to which the wear of contacts can be
approximated to one mechanical operation. OvercurrentLimit x IBase is
defined as the maximum current above which the wear of contacts can be
approximated to saturated level of mechanical operations lost. For more
information, see Figure 43 .
3. Depending on the category, interrupter wear for the operation is calculated as
follows:

n
Y < MinCurrentLimit ® Wear = 1

All threshold values, coefficients (Cz, Pz, corresponding to settings

AblationCoeffz, and PowerCoeffz, where suffix z represents the co-efficient
number), and saturation value (AblatCalShEst ) are specific to a CB type.
Where available, they are provided in the circuit breaker library.
4. Finally, the individual Wear values from all operations are added up into a
cumulated wear value.
5. If cumulated interrupter wear exceeds the set thresholds AblationWarnLevel or
AblationAlarmLevel, a warning or alarm will be raised.

Coefficients AblationCoeffz and PowerCoeffz are determined based on the circuit

breaker’s loading dependency on interrupted current. Standard curve fitting
methods can be used to determine the coefficients such that at any given
interrupted current value in the characteristics, the wear per operation is evaluated
according to above equations.

102
Technical Manual
1MRK 511 275-UEN A Section 7
Controlled Switching and Monitoring

For example, according to Figure 43, using a standard curve fitting method, the
coefficients and thresholds can be approximated as

AblationCoeff0 = C0 = 0
AblationCoeff1 = C1 = 0.10085
AblationCoeff2 = C2 = -0.07959
AblationCoeff3 = C3 = -1.44630
AblationCoeff4 = C4 = 0.15915
PowerCoeff1 = P1 = 1.02393
PowerCoeff2 = P2 = 0.56299
PowerCoeff3 = P3 = -0.78450
PowerCoeff4 = P4 = 0.58511
MinCurrentLimit = 3 kA
OvercurrentLimit · IBase = 63 kA
AblatCalShEst = 1000

Using curve fitting methods, various solutions are possible.

Selection of coefficients should be such that error in approximation
is minimum at the most likely interrupted currents. It is
recommended to contact ABB for obtaining the optimal coefficients
for any circuit breaker type that is not included in the CB library of
SST.

Overcurrent (Fault current) detection GUID-D095AF24-4F47-4441-B64A-C0C7F6DFF1E7 v1

ACBMSCBR can be configured to indicate if the RMS current through the circuit
breaker is higher than a set value. This functionality is always active, not just
during switching operations. It can be useful to identify conditions where
controlled switching was not performed in steady-state situations.

The interfaces for fault detection are listed in Table 62. There is no setting for
disabling the fault current indication output.

The function always monitors within a moving observation window of one power
cycle. If the instantaneous current magnitude is greater than FaultCurrentPercent x
IBase, the current is declared to be fault current. The function will not consider the
instantaneous spikes or noise for fault current detection.

7.2.3.2 Mechanical monitoring GUID-6701B89F-553F-4830-809D-388E062355F4 v1

Mechanical monitoring of the circuit breaker is based on timing information of the

NO (52a) and NC (52b) auxiliary contacts in the drive. Depending upon the
connected inputs, the ACBMSCBR function monitors different mechanical
information in normal operation (that is, not in CB learning mode), see Table 63 for
more information.

NO (52a) is the auxiliary contact that follows the state of the circuit breaker. By
definition, it is closed when the primary contact is fully conducting. A contact of
this type is normally used to interrupt the trip coil current.

NC (52b) is the auxiliary contact that follows the inverse state of the circuit
breaker. By definition, it is closed when the primary contacts are electrically
isolated. A contact of this type is normally used to interrupt the close coil current.

For practical monitoring purposes, the auxiliary contacts’ status is acquired by

precision binary inputs on the PIO hardware module.

To assure accurate contact opening instant detection in case of long

cables between CB drive and the PWC600 IED, discharge resistors
should be connected to each IED input terminal to quickly
discharge the cable capacitance. Recommended ratings are given in
the User manual.

Controlled Switching and Monitoring

Based on the monitored information, ACBMSCBR function tracks the deviation of

mechanical operating times between consecutive operations of the same type
(Close or Open). If the difference is higher than 10% twice in a row, an unstable
alarm will be raised on the UNSTOPOLX output.

If such a deviation is identified, the function declares the circuit breaker as unstable
and stops SSCPOW from issuing further controlled switching commands. All
subsequent operations follow the ContingencyMode setting (that is, they are either
bypassed or blocked). Controlled switching will be allowed only after unstable
mode is reset. Table 67 lists the alarm output and its enabling setting.

UNSTOPOLX Output ACBMSCBR Circuit breaker unstable alarm indication

Disabling the ‘Circuit breaker unstable’ alarm only prevents the

output UNSTOPOLX from going high. This will neither prevent
the functions from entering the unstable mode nor will it exit from
unstable mode. Once the cause has been resolved, unstable mode
must be cleared in the LHMI under Clear/Clear CB indicators/
Clear unstable mode, for each affected CB pole individually. The
same clearing procedure should be followed after changing the
active (that is, set or learned values) mechanical operating times.

7.2.3.3 Combined monitoring GUID-E62BD628-E0A7-4A01-877E-9E7C3F9D0999 v1

Some of the circuit breaker operation characteristics are evaluated based on both
electrical and mechanical monitoring. For example, if auxiliary contacts are not
connected to the IED, the status Open/Closed) of the circuit breaker can be
determined from load current. This electrical status can be used as equivalent
mechanical status for compensation and other calculation and detections.

Status monitoring GUID-EED6B1B1-E51F-4F3B-8902-E3A42908F1FE v1

As described above, the status of the circuit breaker can be determined based on
mechanical and electrical inputs. A circuit breaker can be detected to be electrically
closed if the RMS current flowing through the circuit is above IDead x IBase.
However, this is done only when the load type is set as capacitor, reactor or
coupled reactor. For other preset load types (transformer, line/cable) the load
current may vary and hence this method is not applied. If user-defined load type is
selected, based on the first 10 operations, load monitoring algorithm evaluates
whether the load will draw a fixed current or variable current. During that time, no
electrical status detection is done. The evaluation is restarted when one of the
settings defining the load in SSCPOW (LoadType, Grounding) is changed.

Technical Manual
Section 7 1MRK 511 275-UEN A
Controlled Switching and Monitoring

The load monitoring algorithm computes and evaluates the RMS value of current
for 550 ms, and if the average RMS calculated with in this time is equal, then the
load will be evaluated as fixed load. If the calculated current RMS average is not
equal, the load will be evaluated as variable load. The same procedure will be
repeated for 10 successive operations (5 Close operations and 5 Open operations).

Once the load is identified as fixed, either by setting or by learning for user defined
loads, ACBMSCBR uses the electrically detected status to internally evaluate the
circuit breaker status and to update output interfaces CBSTNOLX and
CBSTNCLX, which are equivalent NO (52a) and NC (52b) of the circuit breaker.
The interfaces used for this functionality are listed in Table 68.

If the mechanical status and electrical status contradict each other, that is, if the
current flowing, mechanical status is Open, the CB position is indicated as
intermediate (“CBInter” mode) and the status indication interfaces in Table 67
reflect the positions of the auxiliary contacts.

The inputs and outputs signifying the breaker status are:

Operation Count GUID-96ADAE79-69F6-4813-8400-8147305B53D2 v1

Every CB close-open cycle is counted as a single operation. Operations are

evaluated in ACBMSCBR for each circuit breaker pole individually. As soon as the
monitoring of each phase is completed, the operation counter is updated. The
update happens after every opening operation. The operation count interfaces are:

The function also raises an alarm and warning for operation count beyond warning
and alarm levels. With every energizing and de-energizing operation of the circuit
breaker, the operation counter is increased. The energization and the de-
energization of the breaker is confirmed after electrical and mechanical (if
available) monitoring. This operation count is used for the below evaluation:
• Operation count alarm and warning: The user can configure to raise an alarm
or warning based on the number of operations that has taken place in the
breaker. These alarming and warning thresholds can be set in the function
MONALM. The alarm and the warning is issued by the ACBMSCBR function
and this can be enabled or disabled based on the setting OpCntAlm.

The operation count can also be reset to zero through LHMI. The LHMI path is

7.2.3.4 Resetting the calculated and acquired values GUID-CF3EEBBC-4F76-4FBD-A58A-5A0786CA645B v1

If the operating environment changes, for example, the circuit breaker has
undergone maintenance or the IED is being used to switch a different breaker, it is
recommended to reset the internal values of accumulated parameters to avoid
erroneous calculations. If the circuit breaker was changed or overhauled during
maintenance and the values are not reset, the functionality may raise alarms. The
clear or resetting options can be accessed through LHMI by navigating to Clear/
Clear CB indicators. For controlling reset functions from the application, the

Monitored parameters are stored in the operation log, see the section on Operation
Log. MONCOMP acts as the data provider by consolidating the parameters for
every circuit breaker operation and retaining them at its outputs until all values are
ready for storing in operation log. SSCPOW triggers the operation log only after
completion of monitoring in all three phases. The monitored values and the
information evaluated in ACBMSCBR are given as inputs to MONCOMP, which
forwards them to OPERLOG for storing in the database. The input information
provided by ACBMSCBR to MONCOMP are:

The PWC600 pre-configuration includes three instances of

ACBMSCBR and of MONCOMP for three phases. The individual
breaker pole (phase) is monitored and data logged independent of
other phases.

Every operation is categorized under one of several different modes after reviewing
the data monitored. The mode of a particular operation is defined by the function
SSCPOW through the output OPLOGMODE, see Table below. Whereas
MONCOMP acts as the data provider to the operation log and triggering of the
operation log is done by SSCPOW.

In addition to acquiring data and publishing them towards the operation log,
MONCOMP and OPERLOG retain the information of the initial operations. These
are also termed as fingerprints. Comparison of the present operations with the
fingerprint operations indicates the deviation that has occurred since initial
commissioning. MONCOMP stores a certain number (defined by setting
InitialRecords) of initial operations as fingerprint records. The initial operations
until InitialRecords are treated as a fingerprint. There are some additional criteria
to fix the number of energizing and de-energizing operations as fingerprints. An
additional setting in MONCOMP, OptCombEqual, determines the fingerprint
records in context of energizing and de-energizing operation. The details of
OptCombEqual are specified in Table below. The interfaces for triggering the
operation log are:

OptCombEqual Setting MONCOMP This setting along with the InitialRecords
determine the number of energizing and de-
energizing operations for fingerprint records.
The enums provided under this setting are:

• EqualOpnClsRcrds: This enum option limits

the fingerprint records to be an equal
number (InitialRecords/2 each) of closing
and opening operations. InitialRecords/2
energizing operations and InitialRecords/2
de-energizing operations are considered as
fingerprint records.
• CombinedTotalRcrds: This enum option
records any sequence of opening and
closing operations as fingerprint records, up
to InitialRecords. Either energizing or de-
enrgizing operation is considered as
fingerprint record, until the total number of
operation reaches the InitialRecords count.

Furthermore, MONCOMP calculates the average values of the data in fingerprint

records and the deviation of the last operation from these average values, see Table
75.

in Table 76. If several modes are applicable to one operation, the one with the
lowest order number is reported.
Table 76: Operation modes as recorded in Operation log
Order/ Mode Numeric Description of conditions
Priority mode
1 Blocked 1451 • Block inputs for a particular command are high when the
command is received
• A contingency exists and the contingency mode has
been selected to block the particular type of operation.
• Synchronous switching commands are blocked by the
BlkSynSw (block synchronous switching) input of
SSCPOW and the contingency mode has been selected
to block the particular operation.

2 RefMiss 1448 When the command was received, there was no proper
reference signal available (see section "Reference signals").
3 Cancel 1446 In case of time synchronization issues, the PIO module may
reject to execute the time stamped output commands as
issued by the SSCPOW function and indicate this through the
Cancel interface. SSCPOW may then attempt to re-issue
updated switching commands.
4 CBInter 1450 For constant load type, disagreement between electrical and
mechanical status of the circuit breaker during switching was
detected. If mechanical status is unknown/faulty, electrical
status is considered and CBInter mode is not declared.
For other load types CBInter mode is not applicable.
5 CBUnstable 1449 When the mechanical operating times are inconsistent
(varying by 10% over previous operating time) for two
consecutive operations.
Close operations are compared with close operations only,
and likewise for opening operations.
when this mode is detected and declared for the first time, all
further operations are declared as either bypassed or blocked
(according to contingency mode) until the CBUnstable mode
is reset by the user.
6 Redundnt 1473 • When a closing command is received while the circuit
breaker is already monitored to be in closed condition.
• When an opening command is received while the circuit
breaker is already monitored to be in open condition.

A circuit breaker is considered to be closed under certain

conditions.

• For constant loads, electrical status takes preference.

• For other loads, mechanical status takes preference if
available.

Absence of auxiliary contacts or detection of intermediate

state will not generate Redundant mode but may generate
Failed mode.

Control

• for indication on the single line diagram (SLD). Position is received through
the IPOS1 and IPOS2 inputs and distributed in the application through the
POS1 and POS2 outputs, or to IEC 61850 through reporting, or GOOSE.
• for commands that are received via the local HMI or IEC 61850 and
distributed in the configuration through outputs CMDPOS12 and CMDPOS21.
The output CMDPOS12 is set when the function receives a CLOSE command
from the local HMI when the SLD is displayed and the object is chosen.
The output CMDPOS21 is set when the function receives an OPEN command
from the local HMI when the SLD is displayed and the object is chosen.

It is important for indication in the SLD that the a symbol is

associated with a controllable object, otherwise the symbol won't be
displayed on the screen. A symbol is created and configured in
GDE tool in PCM600.

The PSTO input is connected to the Local/Remote switch for selecting the
operator's location, either from local HMI (Local) or through IEC 61850 (Remote).
An INTONE connection from Fixed signal function block (FXDSIGN) will allow
operation from local HMI.

As it can be seen, both indications and commands are done in double-bit

representation, where a combination of signals on both inputs/outputs generate the
desired result.

The following table shows the relationship between IPOS1/IPOS2 inputs and the
name of the string that is shown on the SLD. The value of the strings are set in

8.3.2 Functionality GUID-6AD604C0-8AA8-40A0-A797-B5962069837D v2

The strategy switching (SSCPOW) function of PWC600 provides selection of the

relevant switching sequence based on the inputs. The default switching sequence
for closing/opening operations is based on switching command at the relevant
voltage zero or peak of the first possible phase or in accordance to the phase
rotation principle.

SSCPOW processes the voltage/current input and identifies the sequence of zero
crossings for the selection of switching strategy. If the application type is defined
with relevant grounding, the product automatically selects the optimum switching
strategy and performs the operations. However, if there is an application where
these strategies may not result in optimum switching and requires settings, the
switching positions where the operations should be done can be selected. The
switching can also be made adaptable.

The switching strategies mentioned previously can be divided into five subparts.

1. System Application and switching pattern detection (Static Application

Switching Strategy)
2. Source selection and Zero crossing detection (Signal Processing)
3. Case Control Strategy
4. Co-ordination Logic
5. Output Logic

The switching operation also undergoes a circuit breaker learning mode which
confirms the integrity of the wiring, the predicted time stamps and co-ordination
logic between breaker learning logic (a separate function code) and strategy
switching logic.

8.3.6.1 System application and switching pattern detection (Static application

switching strategy) GUID-BC5FC6CB-39F4-4CE3-8FC6-F1B39C4C2836 v1

Different loads and their grounding methods require different switching strategy.
There are nine parameters determining the strategy opening or closing angles.

1. Load type (capacitive or inductive)

2. Load configuration (Star grounded/Star ungrounded/Delta)
3. Phase sequence (Positive/Negative)
4. Operation type (Open/Close)
5. Lead operating phase
6. Reference triggering phase for strategy calculation
7. Phase reference trigger (Positive/Negative)
8. Polarity sensitivity for closing (Positive/Negative/Any)
9. Switching phase

The parameters 1...4 and 8 are handled in the static application switching strategy
and the other parameters are handled in the case control strategy.

8.3.6.2 Source selection and zero-crossing detection GUID-9A34518B-0F95-40A7-A346-9595F8F07B3F v1

The point-on-wave control systems require the input source to be freely selectable.
The three phase-to-earth voltage inputs for closing operation and three phase-to-
earth current inputs for opening operation are required. However, for practical
purposes, all three-phase voltages may not be available at the control kiosk or
phase-to-phase voltages may be available. Hence, it becomes important to be able
to adapt to the inputs being provided and derive the required signals out of the
available signals, by referring to phase to ground voltages phase to phase voltages
positive zero crossing can be derived which is represented in Figure 55 and
appropriate phase voltages and phase to phase voltages are represented in Figure
49. Also, current inputs at times might not be significant in quantity to be
considered for analysis purpose, at such times, falling back on voltage signals
might be a better choice. Due to the above mentioned points, there is a requirement
to choose, reconstruct and analyze different inputs available to achieve the desired
outputs for zero crossing detection.

Once the signal source is selected, the zero crossings are detected and the time
stamp is calculated. This is based on the sample number and the time stamp
information of the initial sample made available.

Figure 51: Reference selection and zero-crossing detection block diagram

As shown in Figure 48, signal processing block is divided into four functional
blocks as shown in Figure 51.
• Reference selection block
• Zero-crossing detection block
• Zero-crossing 3-phase evaluation block
• tp half-cycle block

Internal signal flow between four of the functional blocks is shown in Figure 51.
Also, signal information handshaking is performed using coordination signals
between functional blocks to maintain synchronous data transfer.

Reference selection logic GUID-91FCE7B8-695A-4695-826C-EDD01D8FDE6C v1

The reference selection logic is shown in Figure 52. Based on the setting selected
for the reference signal (Voltage/Current), the logic enables the reference signals to
pass by after checking for the signal amplitude compared to the dead values. If the
level comparison fails, the signal cannot be used as reference signal. The setting
selection information of uConnType and uConnPh is passed through the internal
coordination signal (coorRSZC3E) to zero-crossing 3-phase evaluation logic.

Zero-crossing detection algorithm logic is shown in Figure 53. This logical

diagram describes the evaluation of zero-crossing time with and without polarity
sensitivity. However, in this function the zero-crossing reference is used for target-

The half-cycle time period evaluation is based on the latest zero-crossing time
detected using the presented algorithm. If zero-crossing trigger is detected by zero-
crossing time blocking, it is recorded to a buffer. Based on the length of the buffer,
the defined tpHalfCycle is evaluated as shown in Figure 54.

8.3.6.3 Case Control Strategy GUID-45E5216A-F56D-4B74-9DA8-DC801D4B5D45 v1

The case control strategy consists of ten sub blocks.

General logic Dynamic application switching strategy

Case command control
Query logic BC open query
BC close query
BC close response and ACBMSCBR voltage-based open query
ACBMSCBR voltage-based open response and ACBOM current-based open query
ACBMSCBR current-based open response and ACBOM voltage close query
ACBMSCBR voltage-based close response and delta T5 open query
delta T5 open response and delta T5 close query
delta T5 close response

Dynamic application switching strategy determines the parameter 5,6,7 and 9 of

system application and switching pattern detection section. The selection of the
correct parameters determines the switching strategy.

The Case Command Control block defines the operational procedure for bypass
command, synchronous switching command, cancel command and command turn
off logic. Figure 57 shows the overall block diagram of the case command handling
logic.

The bypass command block defines the operational procedure for the ByPassMode
setting either in open or closed condition. The synchronous switching command
block sends out the open or close command at a defined time stamp corresponding
to the strategy selected. On receiving the cancel command from PIO, this block
issues the correct retrigger commands for open or closed operation.

In case of command control logic, the command turn-off block puts off the closed
or open operation command bit low after the predicted future time.

The sub blocks 1...8 of Figure 48 are the query blocks which puts the query in one
task time and receives the response in the next task time.

Cancel Command Handling Block

Cancel command handling block receives six input cancel commands from the
PIO. Depending on the execution of control operation, either open or close cancel
commands generated by PIO is received as the feedback signal to start the cancel
command handling logic internally. Based on the cancelOperMode setting, cancel
command handling logic executes the operational condition when cancel
commands, that is, abort operation, try once and try twice are received from PIO.

Abort operation

Abort operation executes the emergency trip to give out the three phases open
commands.

Try once

Try once operation executes command re-try once to give out the controlled
switching operation. If cancel commands are received again to the cancel command
handling block then, emergency trip is executed to give out the three phases open
commands.

Try twice

Try twice operation executes command re-try once to give out the controlled
switching operation. If cancel commands are received to the function then this
logic re-tries one more time to execute the controlled switching. If cancel
commands are received again to the cancel command handling block then,
emergency trip is executed to give out the three phases open commands.

Contingency conditions
During non-operational conditions existing such as unstable CB characteristics or
reference signal missing for execution of controlled switching based on the
contingency mode selection two operations are possible.

Uncontrolled switching

Based on the load selected, uncontrolled switching operation leads to the switching
commands with out any control strategy. This operating condition will be indicated
using a unCntSwitching signal to the user to understand due to non-operational
conditions uncontrolled switching happened to the input command received to the
function.

Block commands

Based on the selection of contingency mode the output switching commands can be
blocked irrespective of the operation type selected, when the non-operational
conditions exists to execute the controlled switching.

Bypass Mode
When user selects the bypass mode, the input commands received to the function is
executed with out any controlled switching strategies.

Block sync switching

When blocking of controlled switching is enabled, uncontrolled switching is
indicated stating that the controlled switching strategy is handled when the input
command is received to this function.

CB test mode
The function can also operate in circuit breaker learning mode. This mode confirms
the integrity of the wiring and prediction of time stamps of the function. This mode
acts with co-ordination of the breaker learning function. It accepts the
coorBLSSX input signal and CBTestMode inputs from breaker learning function
to undergo the learning procedure. CBTestMode gives an indication for circuit
breaker learning mode to this function and the coorBLSSX input presents the
required output to be operated on.

coorBLSSX is a six-bit code, with each bit being either 0 or 1. The first three bits
from the LSB side gives the input for open command for the three phases and the
rest three bits from MSB side gives the input for close command for the three
phases.

The Analog scaling ANSCAL function transforms an input signal, for example,
from a monitoring function or input interface, either through linear or non-linear
scaling or interpolation between known relational values for further use. ANSCAL
function is divided into three parts:
• Limit module: limits the input value to either LowLimit or HighLimit whenever
the input value falls below or exceeds the set limits.
• Chart function: scales the output value based on linear interpolation and
constant extrapolation.
• Equation function: evaluates the output as a function of the input based on the
constants declared in Equation 26.

9.1.6.1 Limit module GUID-8EF2E0E7-E719-45B2-9844-74CC7483E7FA v1

The limit module limits the input value to the range between the low limit and the
high limit values specified by the settings LowLimit and HighLimit. The ALARM
output is set to high whenever the input falls below the LowLimit or exceeds the
HighLimit value and the output value from limit module is restricted to LowLimit
or HighLimit value respectively.

LimitScaleVal setting enables the user a choice to limit the output to scaled value or
default value as defined by setting DefValue, in case the input value exceeds the
range defined by LowLimit and HighLimit.

9.1.6.2 Chart function GUID-2AD060DE-E15D-4B93-95C4-3AF700B702B1 v1

Set FnType to Chart mode to enable this functionality. In this mode, the output is
evaluated based on linear interpolation and constant extrapolation. The function
has eight settable input/output relation values. These input and output values are
specified by the settings {X1,Y1} and {X2,Y2} up to {X8,Y8}. Set CurvePoints to
select the required number of input and output relations based on the functionality.
The functionality provides linear interpolation between the points and constant
extrapolation beyond the defined points. The minimum setting points required to
define a linear relationship is 2 and is defined to be the minimum value for
CurvePoints.

The setting points shall be set in such a manner that X2 is greater

than X1, X3 is greater than X2 and so on till X8 is greater than X7.
The settings of LowLimit and HighLimit limit the input values.
Hence the setting of X1 below LowLimit results in output value for
a limited proportional input value of LowLimit. Same is the case for
the last selected curve points based on the setting CurvePoints.

For example, if the input value is lower than X1 , the output is set to Y1. For every
setting n for CurvePoints defined, the output is set to Yn if the input is greater than
Xn. For every input value greater than X1 and less than Xn, the output is calculated
according to the following conditions:

Maximum incremental value of i starting from 2 till maximum of n (n ≤ 8):

Xi such that INPUT ≥ Xi and

Xi +1 such that INPUT < Xi+1

OUTPUT = Yi + (( INPUT - X i ) × (Yi +1 - Yi )) / ( X i +1 - X i )

The WARNING output goes high whenever the input signal is outside the
compensation range but still within the supervision limits. See Table 91.

9.1.6.3 Equation function GUID-4A294515-E959-4956-8364-A6D6728A59B7 v1

Set FnType to Equation mode to enable this functionality. In this mode, the output
is calculated as a function of the input based on the constants declared in equation
28:

y = ax m + bx n + c + d × e f × x

Where,

a,b,c,d,e,f,m and n = Constants (settings)

If x is large and m, n, e are not set to small, the output will

overflow. Similarly, if x can be negative then m and n must be
natural numbers.

In equation mode, the WARNING output goes high when large output value

9.2.6 Operation principle GUID-C6669B23-377E-4B59-86F4-F6CD8AC81AFF v1

The Double point indication status times DPISTTIM function computes the status
times of a double point indication (DPI) by counting the times since the last status
changeovers. The inputs for this function are two boolean signals of a DPI.
DPISTTIM function is intended for computing the idle times (that is, time since the
last open and close operations) of a switch.

The function interprets DPI input combinations as switch status according to Table
95.
Table 95: Input status combination in DPISTTIM
NO NC Status
0 0 Invalid
0 1 Open
1 0 Closed
1 1 Invalid

Invalid input status combinations will generate an alarm or warning if applied for
longer than a grace period defined by TimeToAlm. ALMSTS directly indicates
detection of an invalid input status. CNTWRN indicates that an invalid condition
has been detected even though the outputs show valid time count values; it will be
reset on a valid status transition.

The outputs provide the elapsed time from the last status changeover in the unit
specified by TimeScale (milliseconds, seconds, minutes, or hours). OPNTIME
gives the time since the last closed → open transition; CLSDTIME gives the time
since the last open → closed transition.

156
Technical Manual
1MRK 511 275-UEN A Section 9
General calculation

A rising edge (0 to 1 change) on the RSTTIMS input will reset both OPNTIME
and CLSDTIME to 0.0. The setting ModeStsCntSenErr controls the behavior of the
internal counters and the outputs when an invalid input status is detected for longer
than TimeToAlm.

• If ‘Reset to default’ is selected then both counters will be reset to DefValue.

• If ‘Freeze counters’ is selected the counter outputs are frozen at the current
values. However, internally the counters continue as per the previous valid
input status. If the input status is restored to the same valid status, the outputs
are re-activated to show the updated counter values. If the input status is
restored to the opposite valid status then the counters behave as during a
regular change between valid statuses.
• If ‘Keep counting’ is selected the counters continue counting the last valid
status.

9.3.2 Functionality GUID-78A21286-3731-40C3-9733-1064149C4A0C v1

The binary status signal to analog conversion BINSTSAN function evaluates the
equivalent analog value for a combination of eight binary input signals that show
the status levels of analog quantities. The output signal value is used for further
processing in other functions.

There are three modes which can be used to calculate output signals:
• 1 of n: only one of the inputs can be set to high. If more than one input is high,
an error is detected and the output value is set to the default output.
• Incremental: inputs can go high sequentially and the output value is a sum of
the scaled input values. If the inputs are not going high sequentially, an error is
detected as the inputs are invalid and the output value is set to the default
output.
• Summation: one or more inputs are high in a random order and the output is
the cumulative sum of the scaled input values.

At least one input must be high for a valid output. Else, NOINP
signal is set to TRUE and the output value is set to the default
output.

Functionality D0E6846T201305151403 v1

The Reset-set with memory function block (RSMEMORY) is a flip-flop with

memory that can reset or set an output from two inputs respectively. Each
RSMEMORY function block has two outputs, where one is inverted. The memory
setting controls if the flip-flop after a power interruption will return to the state it
had before or if it will be reset. For a Reset-Set flip-flop, RESET input has higher
priority over SET input.

11.1 Measurements

11.1.1 Functionality D0E5541T201305151403 v1

Measurement functions is used for power system measurement, supervision and

reporting to the local HMI, monitoring tool within PCM600 or to station level for
example, via IEC 61850. The possibility to continuously monitor measured values
of active power, reactive power, currents, voltages, frequency, power factor etc. is
vital for efficient production, transmission and distribution of electrical energy. It
provides to the system operator fast and easy overview of the present status of the
power system. Additionally, it can be used during testing and commissioning of
protection and control IEDs in order to verify proper operation and connection of
instrument transformers (CTs and VTs). During normal service by periodic
comparison of the measured value from the IED with other independent meters the
proper operation of the IED analog measurement chain can be verified. Finally, it
can be used to verify proper direction orientation for distance or directional
overcurrent protection function.

The available measured values of an IED are depending on the

actual hardware (TRM) and the logic configuration made in
PCM600.

All measured values can be supervised with four settable limits that is, low-low
limit, low limit, high limit and high-high limit. A zero clamping reduction is also
supported, that is, the measured value below a settable limit is forced to zero which
reduces the impact of noise in the inputs. There are no interconnections regarding
any settings or parameters, neither between functions nor between signals within
each function.

Zero clampings are handled by ZeroDb for each signal separately for each of the
functions. For example, the zero clamping of U12 is handled by ULZeroDb in
VMMXU, zero clamping of I1 is handled by ILZeroDb in CMMXU.

Dead-band supervision can be used to report measured signal value to station level
when change in measured value is above set threshold limit or time integral of all
changes since the last time value updating exceeds the threshold limit. Measure
value can also be based on periodic reporting.

The measurement function, CVMMXN, provides the following power system

quantities:

187
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

• P, Q and S: three phase active, reactive and apparent power

• PF: power factor
• U: phase-to-phase voltage amplitude
• I: phase current amplitude
• F: power system frequency

The output values are displayed in the local HMI under Main menu/Tests/
Function status/Monitoring/CVMMXN/Outputs

The measuring functions CMMXU, VNMMXU and VMMXU provide physical

quantities:

• I: phase currents (amplitude and angle) (CMMXU)

• U: voltages (phase-to-earth and phase-to-phase voltage, amplitude and angle)
(VMMXU, VNMMXU)

It is possible to calibrate the measuring function above to get better then class 0.5
presentation. This is accomplished by angle and amplitude compensation at 5, 30
and 100% of rated current and at 100% of rated voltage.

The power system quantities provided, depends on the actual

hardware, (TRM) and the logic configuration made in PCM600.

The measuring functions CMSQI and VMSQI provide sequence component

quantities:

• I: sequence currents (positive, zero, negative sequence, amplitude and angle)

• U: sequence voltages (positive, zero and negative sequence, amplitude and
angle).

The CVMMXN function calculates three-phase power quantities by using

fundamental frequency phasors (DFT values) of the measured current respectively
voltage signals. The measured power quantities are available either, as
instantaneously calculated quantities or, averaged values over a period of time (low
pass filtered) depending on the selected settings.

11.1.8 Operation principle

11.1.8.1 Measurement supervision D0E6028T201305151403 v1

The protection, control, and monitoring IEDs have functionality to measure and
further process information for currents and voltages obtained from the pre-
processing blocks. The number of processed alternate measuring quantities
depends on the type of IED and built-in options.

The information on measured quantities is available for the user at different

locations:

• Locally by means of the local HMI

• Remotely using the monitoring tool within PCM600 or over the station bus
• Internally by connecting the analogue output signals to the Disturbance Report
function

Monitoring

Phase angle reference D0E6271T201305151403 v1

All phase angles are presented in relation to a defined reference channel. The
General setting parameter PhaseAngleRef defines the reference. The
PhaseAngleRef is set in local HMI under: Configuration/Analog modules/
Reference channel service values.

Zero point clamping D0E6117T201305151403 v1

Measured value below zero point clamping limit is forced to zero. This allows the
noise in the input signal to be ignored. The zero point clamping limit is a general
setting (XZeroDb where X equals S, P, Q, PF, U, I, F, IL1-3, UL1-3, UL12-31, I1,
I2, 3I0, U1, U2 or 3U0). Observe that this measurement supervision zero point
clamping might be overridden by the zero point clamping used for the
measurement values within CVMMXN.

Continuous monitoring of the measured quantity D0E6118T201305151403 v1

Users can continuously monitor the measured quantity available in each function
block by means of four defined operating thresholds, see Figure 86. The
monitoring has two different modes of operating:

• Overfunction, when the measured current exceeds the High limit (XHiLim) or
High-high limit (XHiHiLim) pre-set values
• Underfunction, when the measured current decreases under the Low limit
(XLowLim) or Low-low limit (XLowLowLim) pre-set values.

X_RANGE is illustrated in Figure 86.

Figure 86: Presentation of operating limits

Each analogue output has one corresponding supervision level output

(X_RANGE). The output signal is an integer in the interval 0-4 (0: Normal, 1:
High limit exceeded, 3: High-high limit exceeded, 2: below Low limit and 4: below
Low-low limit). The output may be connected to a measurement expander block
(XP (RANGE_XP)) to get measurement supervision as binary signals.

207
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

The logical value of the functional output signals changes according to Figure 86.

The user can set the hysteresis (XLimHyst), which determines the difference
between the operating and reset value at each operating point, in wide range for
each measuring channel separately. The hysteresis is common for all operating
values within one channel.

Actual value of the measured quantity D0E6125T201305151403 v1

The actual value of the measured quantity is available locally and remotely. The
measurement is continuous for each measured quantity separately, but the reporting
of the value to the higher levels depends on the selected reporting mode. The
following basic reporting modes are available:

• Cyclic reporting (Cyclic)

• Amplitude dead-band supervision (Dead band)
• Integral dead-band supervision (Int deadband)

Cyclic reporting D0E6126T201305151403 v1

The cyclic reporting of measured value is performed according to chosen setting

(XRepTyp). The measuring channel reports the value independent of amplitude or
integral dead-band reporting.

In addition to the normal cyclic reporting the IED also report spontaneously when
measured value passes any of the defined threshold limits.

Amplitude dead-band supervision D0E6129T201305151403 v1

If a measuring value is changed, compared to the last reported value, and the
change is larger than the ±ΔY pre-defined limits that are set by user (UDbRepIn),
then the measuring channel reports the new value to a higher level. This limits the
information flow to a minimum necessary. Figure 88 shows an example with the
amplitude dead-band supervision. The picture is simplified: the process is not
continuous but the values are evaluated with a time interval of one execution cycle
from each other.

Figure 88: Amplitude dead-band supervision reporting

After the new value is reported, the ±ΔY limits for dead-band are automatically set
around it. The new value is reported only if the measured quantity changes more
than defined by the ±ΔY set limits.

Integral dead-band reporting D0E6136T201305151403 v1

The measured value is reported if the time integral of all changes exceeds the pre-
set limit (XDbRepInt), Figure 89, where an example of reporting with integral
dead-band supervision is shown. The picture is simplified: the process is not
continuous but the values are evaluated with a time interval of one execution cycle
from each other.

The last value reported, Y1 in Figure 89 serves as a basic value for further
measurement. A difference is calculated between the last reported and the newly
measured value and is multiplied by the time increment (discrete integral). The
absolute values of these integral values are added until the pre-set value is
exceeded. This occurs with the value Y2 that is reported and set as a new base for
the following measurements (as well as for the values Y3, Y4 and Y5).

It shall be noted that only in the first two operating modes that is, 1 & 2 the
measurement function calculates exact three-phase power. In other operating
modes that is, from 3 to 9 it calculates the three-phase power under assumption that
the power system is fully symmetrical. Once the complex apparent power is
calculated then the P, Q, S, & PF are calculated in accordance with the following
formulas:

Monitoring

Each analogue output has a corresponding supervision level output (X_RANGE).

The output signal is an integer in the interval 0-4, see section "Measurement
supervision".

Calibration of analog inputs D0E6257T201305151403 v1

Measured currents and voltages used in the CVMMXN function can be calibrated
to get class 0.5 measuring accuracy. This is achieved by amplitude and angle
compensation at 5, 30 and 100% of rated current and voltage. The compensation
below 5% and above 100% is constant and linear in between, see example in
Figure 90.

D0E12329T201305151403 V1 EN-US

The first current and voltage phase in the group signals will be used as reference
and the amplitude and angle compensation will be used for related input signals.

Low pass filtering D0E6228T201305151403 v1

In order to minimize the influence of the noise signal on the measurement it is

possible to introduce the recursive, low pass filtering of the measured values for P,
Q, S, U, I and power factor. This will make slower measurement response to the
step changes in the measured quantity. Filtering is performed in accordance with
the following recursive formula:

213
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

X = k × X Old + (1 - k ) × X Calculated
D0E11928T201305151403 V1 EN-US (Equation 49)

where:
X is a new measured value (that is P, Q, S, U, I or PF) to be given out from the function
XOld is the measured value given from the measurement function in previous execution cycle

XCalculated is the new calculated value in the present execution cycle

k is settable parameter by the end user which influence the filter properties

Default value for parameter k is 0.00. With this value the new calculated value is
immediately given out without any filtering (that is, without any additional delay).
When k is set to value bigger than 0, the filtering is enabled. Appropriate value of k
shall be determined separately for every application. Some typical value for k
=0.14.

Zero point clamping D0E6231T201305151403 v1

In order to avoid erroneous measurements when either current or voltage signal is

not present, the amplitude level for current and voltage measurement is forced to
zero. When either current or voltage measurement is forced to zero automatically
the measured values for power (P, Q & S) and power factor are forced to zero as
well. Since the measurement supervision functionality, included in the CVMMXN
function, is using these values the zero clamping will influence the subsequent
supervision (observe the possibility to do zero point clamping within measurement
supervision, see section "Measurement supervision").

Compensation facility D0E6236T201305151403 v1

In order to compensate for small amplitude and angular errors in the complete
measurement chain (CT error, VT error, IED input transformer errors and so on.) it
is possible to perform on site calibration of the power measurement. This is
achieved by setting the complex constant which is then internally used within the
function to multiply the calculated complex apparent power S. This constant is set
as amplitude (setting parameter PowAmpFact, default value 1.000) and angle
(setting parameter PowAngComp, default value 0.0 degrees). Default values for
these two parameters are done in such way that they do not influence internally
calculated value (complex constant has default value 1). In this way calibration, for
specific operating range (for example, around rated power) can be done at site.
However, to perform this calibration it is necessary to have an external power
meter with high accuracy class available.

Directionality D0E6237T201305151403 v1

CTStartPoint defines if the CTs earthing point is located towards or from the
protected object under observation. If everything is properly set power is always
measured towards protection object.

Figure 91: Internal IED directionality convention for P & Q measurements

Practically, it means that active and reactive power will have positive values when
they flow from the busbar towards the protected object and they will have negative
values when they flow from the protected object towards the busbar.

In some application, for example, when power is measured on the secondary side
of the power transformer it might be desirable, from the end client point of view, to
have actually opposite directional convention for active and reactive power
measurements. This can be easily achieved by setting parameter PowAngComp to
value of 180.0 degrees. With such setting the active and reactive power will have
positive values when they flow from the protected object towards the busbar.

Frequency D0E6242T201305151403 v1

Frequency is actually not calculated within measurement block. It is simply

obtained from the pre-processing block and then just given out from the
measurement block as an output.

11.1.8.3 Phase current measurement CMMXU D0E6243T201305151403 v1

The Phase current measurement (CMMXU) function must be connected to three-

phase current input in the configuration tool to be operable. Currents handled in the
function can be calibrated to get better then class 0.5 measuring accuracy for
internal use, on the outputs and IEC 61850. This is achieved by amplitude and
angle compensation at 5, 30 and 100% of rated current. The compensation below
5% and above 100% is constant and linear in between, see Figure 90.

Phase currents (amplitude and angle) are available on the outputs and each
amplitude output has a corresponding supervision level output (ILx_RANG). The
supervision output signal is an integer in the interval 0-4, see
section "Measurement supervision".

11.1.8.4 Phase-phase and phase-neutral voltage measurements VMMXU,

VNMMXU D0E6252T201305151403 v1

The voltage function must be connected to three-phase voltage input in the

configuration tool to be operable. Voltages are handled in the same way as currents
when it comes to class 0.5 calibrations, see above.

The voltages (phase or phase-phase voltage, amplitude and angle) are available on
the outputs and each amplitude output has a corresponding supervision level output
(ULxy_RANG). The supervision output signal is an integer in the interval 0-4, see
section "Measurement supervision".

11.1.8.5 Voltage and current sequence measurements VMSQI, CMSQI D0E6266T201305151403 v1

The measurement functions must be connected to three-phase current (CMSQI) or

voltage (VMSQI) input in the configuration tool to be operable. No outputs, other
than X_RANG, are calculated within the measuring blocks and it is not possible to
calibrate the signals. Input signals are obtained from the pre-processing block and
transferred to corresponding output.

Positive, negative and three times zero sequence quantities are available on the
outputs (voltage and current, amplitude and angle). Each amplitude output has a
corresponding supervision level output (X_RANGE). The output signal is an
integer in the interval 0-4, see section "Measurement supervision".

11.2.7 Operation principle

D0E6272T201305151403 v1

Event counter CNTGGIO comprises six independent counters. Each counter is

incremented upon activation (0 to 1 transition) of its corresponding COUNTER
input. The updated count number is presented at its VALUE output.

218
Technical Manual
1MRK 511 275-UEN A Section 11
Monitoring

All counter values are stored in flash memory once per hour, to preserve the
information against power loss.

To prevent loss of counter values, always wait for minimum one

hour from the last counter event to powering off the IED.

Activation (0 to 1 transition) of the RESET input resets all six counters to 0, which
takes precedence over any simultaneous COUNTER input activation. Continuous 1
on the RESET input has no effect.

When the BLOCK input is 1 all counters are blocked, that is, they do not react to
changes on their inputs. This takes precedence over any simultaneous COUNTER
input activation. However, RESET will still work even with active BLOCK.

11.2.7.1 Reporting D0E6273T201305151403 v1

The content of the counters can be read in the local HMI.

Reset of counters can be performed in the local HMI or through a binary input.

Reading of content can also be performed remotely, for example from a IEC 61850
client. The value can also be presented as a measuring value on the local HMI
graphical display.

11.3 Disturbance report

11.3.1 Functionality D0E7584T201305151403 v1

Complete and reliable information about disturbances in the primary and/or in the
secondary system together with continuous event-logging is accomplished by the
disturbance report functionality.

Disturbance report DRPRDRE, always included in the IED, acquires sampled data
of all selected analog input and binary signals connected to the function block with
a, maximum of 40 analog and 96 binary signals.

The Disturbance report functionality is a common name for several functions:

219
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder

The Disturbance report function is characterized by great flexibility regarding

configuration, starting conditions, recording times, and large storage capacity.

A disturbance is defined as an activation of an input to the AnRADR or BnRBDR

function blocks, which are set to trigger the disturbance recorder. All connected
signals from start of pre-fault time to the end of post-fault time will be included in
the recording.

Every disturbance report recording is saved in the IED in the standard Comtrade
format as a reader file HDR, a configuration file CFG, and a data file DAT. The
same applies to all events, which are continuously saved in a ring-buffer. The local
HMI is used to get information about the recordings. The disturbance report files
may be uploaded to PCM600 for further analysis using the disturbance handling
tool.

11.3.6 Operation principle

D0E7548T201305151403 v1

Disturbance report DRPRDRE is a common name for several functions to supply

the operator, analysis engineer, and so on, with sufficient information about events
in the system.

The functions included in the disturbance report are:

• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder

Figure 97 shows the relations between Disturbance Report, included functions and
function blocks. Event list , Event recorder and Indications uses information from
the binary input function blocks (BxRBDR). Trip value recorder uses analog
information from the analog input function blocks (AxRADR). Disturbance
recorder DRPRDRE acquires information from both AxRADR and BxRBDR.

The whole disturbance report can contain information for a number of recordings,
each with the data coming from all the parts mentioned above. The event list
function is working continuously, independent of disturbance triggering, recording
time, and so on. All information in the disturbance report is stored in non-volatile
flash memories. This implies that no information is lost in case of loss of auxiliary
power. Each report will get an identification number in the interval from 0-999.

Figure 98: Disturbance report structure

Up to 100 disturbance reports can be stored. If a new disturbance is to be recorded

when the memory is full, the oldest disturbance report is overwritten by the new
one. The total recording capacity for the disturbance recorder is depending of
sampling frequency, number of analog and binary channels and recording time. In a
50 Hz system it is possible to record 100 where the maximum recording time is 0.7

seconds. The memory limit does not affect the rest of the disturbance report (Event
list, Event recorder, Indications and Trip value recorder).

The maximum number of recordings depend on each recordings

total recording time. Long recording time will reduce the number of
recordings to less than 100.

The IED flash disk should NOT be used to store any user files. This
might cause disturbance recordings to be deleted due to lack of disk
space.

11.3.6.1 Disturbance information D0E7544T201305151403 v1

Date and time of the disturbance, the indications, events, and the trip values are
available on the local HMI. To acquire a complete disturbance report the user must
use a PC and - either the PCM600 Disturbance handling tool - or a FTP or MMS
(over 61850) client. The PC can be connected to the IED front, rear or remotely via
the station bus (Ethernet ports).

11.3.6.2 Indications D0E7561T201305151403 v1

Indications is a list of signals that were activated during the total recording time of
the disturbance (not time-tagged), see Indication section for detailed information.

11.3.6.3 Event recorder D0E7562T201305151403 v1

The event recorder may contain a list of up to 150 time-tagged events, which have
occurred during the disturbance. The information is available via the local HMI or
PCM600, see Event recorder section for detailed information.

11.3.6.4 Event list D0E7545T201305151403 v1

The event list may contain a list of totally 1000 time-tagged events. The list
information is continuously updated when selected binary signals change state. The
oldest data is overwritten. The logged signals may be presented via local HMI or
PCM600, see Event list section for detailed information.

11.3.6.5 Trip value recorder D0E7563T201305151403 v1

The recorded trip values include phasors of selected analog signals before the fault
and during the fault, see Trip value recorder section for detailed information.

11.3.6.6 Disturbance recorder D0E7564T201305151403 v1

Disturbance recorder records analog and binary signal data before, during and after
the fault, see Disturbance recorder section for detailed information.

11.3.6.7 Time tagging D0E7547T201305151403 v1

The IED has a built-in real-time calendar and clock. This function is used for all
time tagging within the disturbance report

11.3.6.8 Recording times D0E7565T201305151403 v1

Disturbance report DRPRDRE records information about a disturbance during a

settable time frame. The recording times are valid for the whole disturbance report.
Disturbance recorder, event recorder and indication function register disturbance
data and events during tRecording, the total recording time.

The total recording time, tRecording, of a recorded disturbance is:

tRecording = PreFaultrecT + tFault + PostFaultrecT or PreFaultrecT + TimeLimit, depending on

which criterion stops the current disturbance recording

11.3.6.9 Analog signals GUID-3DA6D334-9EA6-450A-8ABF-3DE80E914463 v1

Up to 40 analog signals can be selected for recording by the Disturbance recorder

and triggering of the Disturbance report function. Out of these 40, 30 are reserved
for external analog signals from analog input modules via preprocessing function
blocks (SMAI). The last 10 channels may be connected to internally calculated
analog signals available as function block output signals (phase differential
currents, bias currents and so on).

Figure 100: Analog input function blocks

The external input signals will be acquired, filtered and skewed and (after
configuration) available as an input signal on the AxRADR function block via the
SMAI function block. The information is saved at the Disturbance report base
sampling rate (4000 and 4800 Hz). Internally calculated signals are updated
according to the cycle time of the specific function. If a function is running at
lower speed than the base sampling rate, Disturbance recorder will use the latest
updated sample until a new updated sample is available.

Application configuration tool (ACT) is used for analog configuration of the

Disturbance report.

The preprocessor function block (SMAI) calculates the residual quantities in cases
where only the three phases are connected (AI4-input not used). SMAI makes the
information available as a group signal output, phase outputs and calculated
residual output (AIN-output). In situations where AI4-input is used as an input

246

1MRK 511 275-UEN A Section 11
Monitoring

signal the corresponding information is available on the non-calculated output

(AI4) on the SMAI function block. Connect the signals to the AxRADR
accordingly.

For each of the analog signals, Operation = On means that it is recorded by the
disturbance recorder. The trigger is independent of the setting of Operation, and
triggers even if operation is set to Off. Both undervoltage and overvoltage can be
used as trigger conditions. The same applies for the current signals.

If Operation = Off, no waveform (samples) will be recorded and reported in graph.

However, Trip value, pre-fault and fault value will be recorded and reported. The
input channel can still be used to trig the disturbance recorder.

If Operation = On, waveform (samples) will also be recorded and reported in

graph.

The analog signals are presented only in the disturbance recording, but they affect
the entire disturbance report when being used as triggers.

11.3.6.10 Binary signals D0E7538T201305151403 v1

Up to 96 binary signals can be selected to be handled by disturbance report. The

signals can be selected from internal logical and binary input signals. A binary
signal is selected to be recorded when:

• the corresponding function block is included in the configuration

• the signal is connected to the input of the function block

Each of the 96 signals can be selected as a trigger of the disturbance report

(Operation = Off). A binary signal can be selected to activate the yellow (START)
and red (TRIP) LED on the local HMI (SetLED = Off/Start/Trip/Start and Trip).

The selected signals are presented in the event recorder, event list and the
disturbance recording. But they affect the whole disturbance report when they are
used as triggers. The indications are also selected from these 96 signals with local
HMI IndicationMask=Show/Hide.

11.3.6.11 Trigger signals D0E7539T201305151403 v1

The trigger conditions affect the entire disturbance report, except the event list,
which runs continuously. As soon as at least one trigger condition is fulfilled, a
complete disturbance report is recorded. On the other hand, if no trigger condition
is fulfilled, there is no disturbance report, no indications, and so on. This implies
the importance of choosing the right signals as trigger conditions.

A trigger can be of type:

• Manual trigger
• Binary-signal trigger
• Analog-signal trigger (over/under function)

247
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

Manual trigger D0E7540T201305151403 v1

A disturbance report can be manually triggered from the local HMI, PCM600 or
via station bus (IEC 61850). When the trigger is activated, the manual trigger
signal is generated. This feature is especially useful for testing.

Binary-signal trigger D0E7541T201305151403 v1

Any binary signal state (logic one or a logic zero) can be selected to generate a
trigger ( Triglevel = Trig on 0/Trig on 1). When a binary signal is selected to
generate a trigger from a logic zero, the selected signal will not be listed in the
indications list of the disturbance report.

Analog-signal trigger D0E7542T201305151403 v1

All analog signals are available for trigger purposes, no matter if they are recorded
in the disturbance recorder or not. The settings are OverTrigOp, UnderTrigOp,
OverTrigLe and UnderTrigLe.

The check of the trigger condition is based on peak-to-peak values. When this is
found, the absolute average value of these two peak values is calculated. If the
average value is above the threshold level for an overvoltage or overcurrent trigger,
this trigger is indicated with a greater than (>) sign with the user-defined name.

If the average value is below the set threshold level for an undervoltage or
undercurrent trigger, this trigger is indicated with a less than (<) sign with its name.
The procedure is separately performed for each channel.

This method of checking the analog start conditions gives a function which is
insensitive to DC offset in the signal. The operate time for this start is typically in
the range of one cycle, 20 ms for a 50 Hz network.

All under/over trig signal information is available on the local HMI and PCM600.

11.3.6.12 Post Retrigger D0E7543T201305151403 v1

Disturbance report function does not automatically respond to any new trig
condition during a recording, after all signals set as trigger signals have been reset.
However, under certain circumstances the fault condition may reoccur during the
post-fault recording, for instance by automatic reclosing to a still faulty power line.

In order to capture the new disturbance it is possible to allow retriggering

(PostRetrig = On) during the post-fault time. In this case a new, complete recording
will start and, during a period, run in parallel with the initial recording.

When the retrig parameter is disabled (PostRetrig = Off), a new recording will not
start until the post-fault (PostFaultrecT or TimeLimit) period is terminated. If a new
trig occurs during the post-fault period and lasts longer than the proceeding
recording a new complete recording will be started.

Disturbance report function can handle maximum 3 simultaneous disturbance

recordings.

11.4.1 Functionality D0E7475T201305151403 v1

To get fast, condensed and reliable information about disturbances in the primary
and/or in the secondary system it is important to know, for example binary signals
that have changed status during a disturbance. This information is used in the short
perspective to get information via the local HMI in a straightforward way.

There are three LEDs on the local HMI (green, yellow and red), which will display
status information about the IED and the Disturbance recorder function (triggered).

The Indication list function shows all selected binary input signals connected to the
Disturbance recorder function that have changed status during a disturbance.

one or state changes from logic one to logic zero will not be visible in the list of
indications. Signals are not time tagged. In order to be recorded in the list of
indications the:

• the signal must be connected to binary input BxRBDR function block

• the DRPRDRE parameter Operation must be set On
• the DRPRDRE must be trigged (binary or analog)
• the input signal must change state from logical 0 to 1 during the recording
time.

11.5.1 Functionality D0E7582T201305151403 v1

Quick, complete and reliable information about disturbances in the primary and/or
in the secondary system is vital, for example, time-tagged events logged during
disturbances. This information is used for different purposes in the short term (for
example corrective actions) and in the long term (for example functional analysis).

The event recorder logs all selected binary input signals connected to the
Disturbance recorder function. Each recording can contain up to 150 time-tagged
events.

The event recorder information is available for the disturbances locally in the IED.

The event recording information is an integrated part of the disturbance record

(Comtrade file).

Section 11 1MRK 511 275-UEN A
Monitoring

11.5.4 Operation principle D0E7533T201305151403 v1

When one of the trig conditions for the disturbance report is activated, the event
recorder logs every status change in the 96 selected binary signals. The events can
be generated by both internal logical signals and binary input channels. The
internal signals are time-tagged in the main processor module, while the binary
input channels are time-tagged directly in each I/O module. The events are
collected during the total recording time (pre-, post-fault and limit time), and are
stored in the disturbance report flash memory at the end of each recording.

In case of overlapping recordings, due to PostRetrig = On and a new trig signal

appears during post-fault time, events will be saved in both recording files.

The name of the binary input signal that appears in the event recording is the user-
defined name assigned when configuring the IED. The same name is used in the
disturbance recorder function , indications and event recorder function.

The event record is stored as a part of the disturbance report information and
managed via the local HMI or PCM600.

Events can not be read from the IED if more than one user is
accessing the IED simultaneously.

Continuous event-logging is useful for monitoring the system from an overview

perspective and is a complement to specific disturbance recorder functions.

11.6.4 Operation principle D0E7575T201305151403 v1

When a binary signal, connected to the disturbance report function, changes status,
the event list function stores input name, status and time in the event list in
chronological order. The list can contain up to 1000 events from both internal logic
signals and binary input channels. If the list is full, the oldest event is overwritten
when a new event arrives.

The list can be configured to show oldest or newest events first with a setting on
the local HMI.

The event list function runs continuously, in contrast to the event recorder function,
which is only active during a disturbance.

The name of the binary signal that appears in the event recording is the user-
defined name assigned when the IED is configured. The same name is used in the
disturbance recorder function , indications and the event recorder function .

The event list is stored and managed separate from the disturbance report
information .

11.7 Trip value recorder D0E7579T201305151403 v1

11.7.1 Functionality D0E7583T201305151403 v1

Information about the pre-fault and fault values for currents and voltages are vital
for the disturbance evaluation.

The Trip value recorder calculates the values of all selected analog input signals
connected to the Disturbance recorder function. The result is magnitude and phase
angle before and during the fault for each analog input signal.

The trip value recorder information is available for the disturbances locally in the
IED.

The trip value recorder information is an integrated part of the disturbance record
(Comtrade file).

11.7.2 Function block D0E7879T201305151403 v1

The Trip value recorder has no function block of it’s own.

11.7.3 Signals

11.7.3.1 Input signals D0E7880T201305151403 v1

The trip value recorder function uses analog input signals connected to A1RADR
to A3RADR (not A4RADR).

11.7.4 Operation principle D0E7534T201305151403 v1

Trip value recorder calculates and presents both fault and pre-fault amplitudes as
well as the phase angles of all the selected analog input signals. The parameter
ZeroAngleRef points out which input signal is used as the angle reference.

When the disturbance report function is triggered the sample for the fault
interception is searched for, by checking the non-periodic changes in the analog
input signals. The channel search order is consecutive, starting with the analog
input with the lowest number.

When a starting point is found, the Fourier estimation of the pre-fault values of the
complex values of the analog signals starts 1.5 cycle before the fault sample. The
estimation uses samples during one period. The post-fault values are calculated
using the Recursive Least Squares (RLS) method. The calculation starts a few
samples after the fault sample and uses samples during 1/2 - 2 cycles depending on
the shape of the signals.

254
Technical Manual
1MRK 511 275-UEN A Section 11
Monitoring

If no starting point is found in the recording, the disturbance report trig sample is
used as the start sample for the Fourier estimation. The estimation uses samples
during one cycle before the trig sample. In this case the calculated values are used
both as pre-fault and fault values.

The name of the analog signal that appears in the Trip value recorder function is
the user-defined name assigned when the IED is configured. The same name is
used in the Disturbance recorder function .

11.8.1 Functionality D0E7585T201305151403 v1

The Disturbance recorder function supplies fast, complete and reliable information
about disturbances in the power system. It facilitates understanding system
behavior and related primary and secondary equipment during and after a
disturbance. Recorded information is used for different purposes in the short
perspective (for example corrective actions) and long perspective (for example
functional analysis).

The Disturbance recorder acquires sampled data from selected analog- and binary
signals connected to the Disturbance recorder function (maximum 40 analog and
96 binary signals). The binary signals available are the same as for the event
recorder function.

The function is characterized by great flexibility and is not dependent on the

operation of protection functions. It can record disturbances not detected by
protection functions. Up to 9,9 seconds of data before the trigger instant can be
saved in the disturbance file.

The disturbance recorder information for up to 100 disturbances are saved in the
IED and the local HMI is used to view the list of recordings.

11.8.5 Operation principle D0E7531T201305151403 v1

D0E7568T201305151403 v1

Disturbance recording is based on the acquisition of binary and analog signals. The
binary signals can be either true binary input signals or internal logical signals
generated by the functions in the IED. The analog signals to be recorded are input
channels from the Transformer Input Module (TRM) through the Signal Matrix
Analog Input (SMAI) and some internally derived analog signals.

Disturbance recorder collects analog values and binary signals continuously, in a

cyclic buffer. The pre-fault buffer operates according to the FIFO principle; old
data will continuously be overwritten as new data arrives when the buffer is full.
The size of this buffer is determined by the set pre-fault recording time.

Upon detection of a fault condition (triggering), the disturbance is time tagged and
the data storage continues in a post-fault buffer. The storage process continues as
long as the fault condition prevails - plus a certain additional time. This is called
the post-fault time and it can be set in the disturbance report.

The above mentioned two parts form a disturbance recording. The whole memory,
intended for disturbance recordings, acts as a cyclic buffer and when it is full, the
oldest recording is overwritten. Up to the last 100 recordings are stored in the IED.

The time tagging refers to the activation of the trigger that starts the disturbance
recording. A recording can be trigged by, manual start, binary input and/or from
analog inputs (over-/underlevel trig).

A user-defined name for each of the signals can be set. These names are common
for all functions within the disturbance report functionality.

11.8.5.1 Memory and storage D0E7569T201305151403 v1

The maximum number of recordings depend on each recordings

total recording time. Long recording time will reduce the number of
recordings to less than 100.

Technical Manual
1MRK 511 275-UEN A Section 11
Monitoring

The IED flash disk should NOT be used to store any user files. This
might cause disturbance recordings to be deleted due to lack of disk
space.

When a recording is completed, a post recording processing occurs.

This post-recording processing comprises:

• Saving the data for analog channels with corresponding data for binary signals
• Add relevant data to be used by the Disturbance handling tool (part of PCM
600)
• Compression of the data, which is performed without losing any data accuracy
• Storing the compressed data in a non-volatile memory (flash memory)

The recorded disturbance is now ready for retrieval and evaluation.

The recording files comply with the Comtrade standard IEC 60255-24 and are
divided into three files; a header file (HDR), a configuration file (CFG) and a data
file (DAT).

The header file (optional in the standard) contains basic information about the
disturbance, that is, information from the Disturbance report sub-functions. The
Disturbance handling tool use this information and present the recording in a user-
friendly way.

General:

• Station name, object name and unit name

• Date and time for the trig of the disturbance
• Record number
• Sampling rate
• Time synchronization source
• Recording times
• Activated trig signal
• Active setting group

Analog:

• Signal names for selected analog channels

• Information, for example, trig on analog inputs
• Primary and secondary instrument transformer rating
• Over- or Undertrig: level and operation
• Over- or Undertrig status at time of trig
• CT direction

Binary:

• Signal names
• Status of binary input signals

The configuration file is a mandatory file containing information needed to

interpret the data file. For example sampling rate, number of channels, system
frequency, channel info etc.

The data file, which also is mandatory, containing values for each input channel for
each sample in the record (scaled value). The data file also contains a sequence
number and time stamp for each set of samples.

11.13 Operation log GUID-7406E8A3-F03D-4C8E-82B0-1DAEFE891A82 v1

Operation log is a database for storing operational data related to a trigger event. It
can be used, for example, storing the set values associated with a switching
operation of the circuit breaker or an alarm status activation, or for storing a set of
values every few hours using a periodic trigger.

Stored operation records can be viewed on the LHMI or through WHMI.

Furthermore, graphical summaries can be created in the Trend views of WHMI.
This information can be used in the short term (for example, corrective actions) and
in the long term (for example, functional analysis).

Two types of records are supported:

• Operation records for storing current data.
• Fingerprint records for storing initial data obtained during commissioning.
These are intended as a reference for analysis of changes over time.

Figure 105: Operation log system overview

• This function saves records of input values to a persistent memory (flash)

based on a trigger. The connected input values can be calculated data from
different functions or measured process data.
• The records that are logged by the operation log component can be viewed in
LHMI and WHMI as common data or phase segregated data. If the signal
connected has an associated unit, it will also be displayed.
• The memory supervision component MONMEMSUP monitors the overall
memory consumed by all operation log components instantiated in the IED.
Even though there is a provision for setting maximum records for every
instance of operation log, it is the memory supervision which finally checks
the IED capacity. If the size of the database exceeds the available memory of
40MB, the newest record will overwrite the oldest one. One record created by
one instance of OPLOG will consume approximately 80 Byte of data,
irrespective of the number of input channels connected to that component.
• By a specific triggering option, a stored operation record can be marked as
“fingerprint record”. Fingerprint records are retained during normal clearing of
the operation log database, neither will they be overwritten in case of memory
overrun. The number of fingerprint records is limited to 50 (settable); storing
another fingerprint record after reaching this limit will overwrite the oldest
fingerprint record.

A mechanism for limiting the number of write operations per time

period is implemented in the IED, to prevent the flash memory
from wearing out. As a consequence, it may take up an hour to save
new operation records permanently in the database. If the auxiliary
power is interrupted before new data are saved, these data are lost.
The time of flash saving is neither indicated on the IED nor can it
be influenced by the user.

Triggering GUID-9D993A77-AC86-412C-B2C6-50DB0DA06A29 v1

Storing of an operation record is triggered by the input signal TRIG_IN going high.
TRIG_IN is primarily a binary signal. Depending on the application, it may be
augmented by additional data to form a composite signal.

If the application is to store operation data of the circuit breaker along with the
time stamp and operation type, a composite trigger signal should be applied
comprising the following information.
• Time stamp provided by the application, for example, the time when a
command has been received
• Circuit breaker operation type (Close or Open)
• Whether the data should be stored as fingerprint record

In the Switchsync PWC600 pre-configuration, the OPLOGTRIG output of

SSCPOW provides such a composite trigger signal. TsSrcSel should be set to
“Signal Time” to assure correct storing of the application generated time stamp.

In an application for periodic process monitoring (for example, maximum

temperature attained in a day), where measured data are stored immediately on
triggering, a simple binary (Boolean) signal can be used to trigger OPERLOG. In
this case, TsSrcSel should be set to “System Time”, to generate the time stamp from
the IED’s system time when TRIG_IN was activated. In this case, the CB operation
type (Close or Open) will be stored as “not applicable”.

Processing of trigger signals can be further controlled by the TrgModOpn (for open
operation) and TrgModCls (for close operation) parameters. The options are:
• Do not log: A trigger signal for the respective operation (Close or Open) will
not store an operation record.
• Log without values: Operation record will include only the operation type
(Close or Open) and the time stamp.
• Log with values: Operation record will include operation type (Close or
Open), time stamp, and the values at the connected inputs.

Grouping and categorizing operation data GUID-CCD13914-71C3-40B8-9D3C-889DAF3D640F v1

To enable grouped and categorized presentation of logged data in LHMI or WHMI,

two settings and one input are provided. One instance of OPERLOG allows to
connect maximum eight real-value inputs; if more than eight values are to be
logged with the same trigger signal, additional function block instances are
required. To logically group these instances together in the database, Type should
be set to the same value.

If, within one Type of OPERLOG, a client such as trend graph page in WHMI is
configured to show the values of selected inputs only, the InputxGroup settings
allow this segregation. They should be set according to the class of monitored
process data, for example, “Accuracy” (of controlled switching operations) or
“Ambient” (temperature).

272
Technical Manual
1MRK 511 275-UEN A Section 11
Monitoring

The input signal MODE, which is stored together with the other input data,
provides dynamic categorization (at runtime). It is intended to give a status
evaluation of each switching operation at a glance. This mode information is
further explained in the User Manual, section IED Operation.

Configuring instances in ACT GUID-0F13DEE4-647F-4178-A349-7AB7060D8D60 v1

Operation log instances can be configured to store phase segregated values such as
operation times of the three circuit breaker poles, or phase independent values such
as ambient temperature.

Do not connect more than three components in a daisy chain.

For phase independent signals, configure OPERLOG as individual instance(s). An

example of possible trigger connections is shown in Figure 106.

• Individual instances do not have any input or output daisy chain connection to
any other operation log component.
• Primary instances have only output daisy chain connection to the secondary
operation log component.
• Secondary instances have input daisy chain connection to a primary or
secondary operation log component and possibly an output daisy chain
connection to another secondary instance.

With one or more operation records already stored in the database,

changes in OPERLOG related ACT configuration or in OPERLOG
parameters may lead to wrong reporting on LHMI or WHMI.

To prevent wrong reporting after configuration changes, the following procedure

should be observed:
1. Download the operation log database through WHMI.
2. Write configuration changes to the IED.
3. Clear all operation records and fingerprint records in the IED.

11.15.2 Functionality GUID-596AE73E-CFE2-4AB2-9115-0903949FD910 v2

To achieve accurate controlled switching, a point-on-wave controller needs to take

into account the estimated operating times of the circuit breaker. Depending on the
design, mechanical closing and opening times may be affected by variations in
external conditions such as:

275
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

• Control voltage
• Temperature
• Drive energy
• Idle time (that is, time elapsed since last circuit breaker operation)

Each quantity that is measured can be converted into a compensation value (that is,
deviation in milliseconds from the nominal operating time) – in PWC600 this is
done by the ANSCAL function block.

The compensation of circuit breaker switching times (CBCOMP) function provides

combined compensation by adding up all available individual compensation values
for each CB pole. The resulting total compensation values (one per pole) take into
account the quantity and health status of sensors and the CB operation type
(closing or opening). In controlled switching, this is used to optimize prediction of
the circuit breaker operating times for precise switching instants. CBCOMP has
pre-defined inputs for the compensation values of the external parameters listed
above. Furthermore, it provides two groups of spare inputs, which may be used to
compensate additional measured quantities.

11.15.7 Operation principle GUID-7AA751F1-8726-48D9-BE07-072A5A905CDD v1

In order to optimize the predicted circuit breaker switching times, analog

parameters such as idle time, control voltage, ambient temperature, drive pressure,
and spring charge can be monitored periodically through appropriate sensors. In a
typical application, ANSCAL converts each sensor signal to a compensation value
(that is, time deviation from nominal operating time), which is then supplied to
CBCOMP. All associated compensation values are added to yield three total
compensation values DELTAT2Lx, one per phase. See Figure 109.

The number of available sensors and their respective health status are taken into
account for the calculations. Each compensation scheme can be configured to
provide compensation for Open operations, Close operations, or both. For each
parameter to be compensated, CBCOMP features a dedicated group of
compensation values inputs, as explained in Table 217.

11.15.7.1 Compensation mode GUID-61A1575E-523A-4D9E-AEE3-16C60D0F621B v1

Depending on the number of sensors available for a given parameter, and on the
circuit breaker operations to be controlled (or compensation characteristics
available), the respective value for CompModeSel defines the compensation mode
applied to that parameter. See Table 218. In Switchsync PWC600, this selection
can be made automatically by SST.

With three sensors enabled, individual compensation values are processed for each
CB pole. With only a single sensor input enabled, the compensation value on the
input for breaker pole L1 is used for all three poles.

11.15.7.2 Sensor status GUID-C6447FBC-1F8E-4785-9F0B-D409BEAE0B5C v1

Only accurate measured values from the sensors are useful in optimizing controlled
switching performance. In case of a faulty sensor, wrong output values may even
deteriorate the result. As part of the input group signals, CBCOMP accepts health
status information of each sensor, where logical 1 indicates a missing or faulty
sensor. Any ‘unhealthy’ condition indication on an enabled sensor input activates
the LOSCOPSG output. Unacceptable numbers of faulty sensors, which do not
meet the criterion defined by the ErrInpOpt setting, activate the ALMSTS output.
Furthermore, the sensor failure information can be used for selecting a fallback
strategy. This assumes that operating conditions for three adjacent circuit breaker
poles would generally be similar. The strategies also depend on the ErrInpOpt
setting for each measured parameter, see Table 219.

Monitoring and compensation of circuit breaker MONCOMP function provides an

overall compensation for different operating and controlling parameters which can
be monitored and adapted for better accuracy such as, Pre-strike, Re-ignition and
mechanical operating time for PWC600’s synchronous switching functionality.
MONCOMP provides single or three phase compensation modes, predicted
correction times, deviation from the fingerprint values and drift from the
fingerprint values.

11.16.7.1 Coordination logic GUID-487CD3F7-D62A-456F-BD8E-1AB0EEE46920 v1

The coordination logic block describes the adaptive switching times compensation
for the systematic variation of circuit breaker operating time. Based on the received
coordination inputs from other functions such as, StrategySwitching (coorSSMC),
Pre-strike (coorPSMC), Re-strike (coorRSMC), correction times are considered for
open or close operations. Electrical correction and mechanical correction times are
considered for evaluating overall compensation for the circuit breaker operating
time, ideal RRDS (Rate of Raise of Dielectric Strength) related correction for
opening operations (Re-strike/Re-ignition) correction time and ideal RDDS (Rate
of Decay of Dielectric Strength) related correction for closing operations (Pre-
strike) correction time. Both Pre-strike and Re-ignition/Re-srtike correction times
adaptively vary to provide the overall compensation for the varying circuit breaker
operating time. Summation of deltaT1XR, deltaT1XP is considered as deltaT1X,
summation of deltaT3XR, deltaT3XP is considered as deltaT3X and deltaT7XR is
considered as deltaT7X.

Figure 112: Coordination signal flow diagram

The coordination signal flow used in PWC600 shown in Figure 112 is based on the
concepts of subscriber/publisher. This ensures that in no conditions (both open,
close command going high or wrong ACT connections) the command operation
compensation or correction evaluation result in wrong operation. The difference
from the subscriber/publisher concept to the adaptation here is, the additional
triggering permit signal is required along with the subscriber. Consider an example,
when an open command is received and which resets in a few milliseconds (>5ms
required as per PWC requirements) and a close command input is high or both go
high together, then the functionality blocks compensation and allows a reduced
accuracy switching or ideally possible switching is performed.

Open/close command input is received by all the function blocks as shown in

Figure 112. Coordination signal contains various information which is exchanged
between function blocks to execute the evaluations synchronously with each other.
Any discrepancy (for example, mismatch of command input status between
functions) is reported as an alarm to the user. All the coordination signals from
other function blocks is reported to Monitoring Compensation (MONCOMP)
function to check for operation values reporting. Coordination signal logic flow
diagram in MonitoringCompensation which describes coordination signal bit wise
control is shown in Figure 112. Predicted values (PredictedValue) and actual values
(ActualValue) are filtered out from input value received from Pre-strike and Re-
strike functions according to the status of the coordination signal. During close
operation, parameters related to the open operation have no relevance and vice-
versa for open operation to close operation parameters. Hence, when a variable has
no relevance, that is, it is not applicable for database management, a very high
positive value is logged which can be filtered off later. However, if an operation
fails or particular parameter could not be evaluated during an operation before the
time out, a zero value cannot be stored as for some parameters it might mean an
ideal operation.

11.16.7.2 Fingerprint average logic GUID-6D6F4F61-1FDB-44B7-9DB0-62FB1F69F4A7 v1

The fingerprint average logic block describes the evaluation of initial fingerprint
operations, average of correction times for various operating and controlling
parameters such as, mechanical opening/closing time, electrical opening/closing
time and Pre-striking angle. Actual values of operating/controlling parameters and
predicted values of operating/controlling parameters is fed from ACBMSCBR
(Advanced Circuit Breaker Operation Monitoring) functions. This block selects the
actual/predicted values based on coordination signal inputs received from
ACBMSCBR functions. Cumulative average of actual and predicted parameters is
evaluated to monitor the variation of actual and predicted values for initial
fingerprint records. Figure 114 depicts the flow of cumulative average computation
for both predicted and actual operating/controlling parameters for initial fingerprint
operations. Computed average for different controlling/operating parameters of CB
is used to evaluate deviation of actual/predicted values from the initial fingerprint
operations.

11.16.7.3 Deviation from average logic GUID-92C024B6-932D-42B6-9BCD-19893C67CE0C v1

The deviation from average logic block describes the deviation of correction times
for various operating and controlling parameters such as, mechanical opening/
closing time, electrical opening/closing time and Pre-striking angle. Predicted/
actual average values of operating/controlling parameters and actual/predicted
values of operating/controlling parameters, differes in the deviation from respective
actual/predicted parameters. Figure 115 depicts the calculation of deviation of
actual/predicted values from average of initial fingerprint operations of different
operating/controlling parameters of CB. Computed deviation values are used to
evaluate drift of actual/predicted values from the initial fingerprint operations.

11.16.7.4 Drift average logic GUID-E8019CE4-C4DD-4EE6-B20D-45C6F13BC25A v1

Drift is the cumulative average deviation of a parameter (either predicted/actual)

from the average fingerprint values. Drift gives a good explanation about parameter
deviation as an average. Deviation is only the current operation's measure.
However, drift accumulates the deviation of a steady drift value ideally near zero,
which indicates that the POW (point on wave) control occurs steadily on the CB. A
flickering drift value suggests that the CB POW control is not operating the
intended way. Drift average calculation comprises of deviation of operating/
controlling parameters of CB from the actual/predicted parameters. Drift average,
calculated to estimate the drift of actual/predicted values or operating/controlling
parameters of CB for the initial fingerprint operations, helps the user to estimate
the variation trend of CB performance parameters over a certain operating time.
Figure 116 depicts drift evaluation logic for actual/predicted operating/controlling
parameters.

11.17.2 Functionality GUID-92C746A1-FFCA-42A5-BB58-7F00D25D57C5 v2

MONALM is used to monitor up to 9 groups of measured or calculated analog

values, to ascertain whether they are within a defined “normal” range as per the
process requirements. The function compares each input value against 1…4
threshold levels and indicates the range in which it is currently residing. Values
outside the normal range are indicated by a warning or alarm.

The numerical range information can be decoded into binary status signals by other
functions such as MVEXP, for example, to control a LED or binary output or to
generate an event.

Furthermore, MONALM monitors one group of binary inputs, which represent

alarm levels, and replicates the input values to corresponding output signals. These
signals are also used to indicate the operational capability of the circuit breaker.

A quick indication of the overall status can be obtained from two alarm status
outputs, which summarize the conditions of 5 input groups each.

11.17.7 Operation principle GUID-BC2E5956-4F45-4B85-BD83-AF4691E0ACDE v1

The Multilevel threshold alarm generation MONALM function triggers an alarm

when an analog quantity is not in a normal range.

MONALM works on the principle of comparing the analog quantity against a set
of thresholds in two directions at two different levels on either side. Nine analog
quantities, for example, control voltage, temperature, drive pressure, spring
pressure and so on can be monitored such that when they exceed the threshold
values, alarms are generated. The binary signals are the supervising levels of an
analog signal, whose status level (for example, gas pressure, spring charge status
and so on) indicates when the analog signal falls below the threshold.

Use the setting InpxSensorMode to select either 1 Sensor Mode or 3 Sensor Mode
operation. Select 1 Sensor Mode if a single sensor signal is connected to the
corresponding IxL1 input, else select 3 Sensor Mode for three sensor signals (one
per phase).

Up to nine analog input signals can be supervised. For each signal, one or two
supervision thresholds can be configured in each direction, or supervision can be
disabled altogether in any direction.

316
Technical Manual
1MRK 511 275-UEN A Section 11
Monitoring

The binary input level alarm can be configured to indicate Warning, Alarm and/or
High Alarm.
• If the full level binary signal is high, no warning or alarm is generated,
regardless of the status of the other binary signals.
• If the full level binary signal is low and the medium level signal is high,
Warning goes high.
• If only the low level signal is high, Alarm goes high.
• If all binary inputs are low, High Alarm goes high.

For analog quantities, exceeding the thresholds can trigger one of the four alarms.
The output ALRxLn can have different values according to the conditions defined
below:
• 0 (normal range) indicates, the input signal is in normal range, that is, between
low and high warning limits, or the alarm input IxALn is high
• 1 (high warning) indicates, the signal has risen to or above InpxHiLimit
• 2 (low warning) indicates, the signal has dropped to or below InpxLoLimit
• 3 (high alarm) indicates, the signal has risen to or above InpxHiHiLimit
• 4 (low alarm) indicates, the signal has dropped to or below InpxLoLoLimit

where x indicates the analog input and n indicates the phase.

The input value 1.175494E-38, which is the smallest possible real

value, is not evaluated for determining the range and is always
treated as in Normal range, regardless of the set limits. The purpose
is to prevent raising of alarms on quantities that have no defined
value, for example, a switching time if the circuit breaker has not
been operated yet.

MONALM also generates a general alarm (gives information) when any one of the
alarming condition is present or when a signal connected to IxALn goes high. Loss
of the sensor signal of the monitored analog signals can be connected to this.

11.17.7.1 Alarm status logic GUID-19430436-DA44-4966-994A-10723961982D v1

The status of the supervision alarm is indicated by an alarm status functionality

which is designed to bit pack the alarm status of all ten input groups into two
integer signals. The sequential bits carry the status information of each analog
input group for all the three phases independently. The phase information for every
input is described using two bits, where the least significant bit (LSB) indicates
warning and the most significant bit (MSB) indicates alarm or high alarm.

The alarm status information for phase L1,

• If the signal is in low or high warning range, the LSB is set high.
• If the signal is in low or high alarm range, the MSB is set high.
• If alarm input signal IxALL1 is high, both MSB and LSB are set high (this
indicates the status of signal's health).
• In all other conditions both MSB and LSB are set low.

Figure 118 shows the alarm status processing of the analog inputs and a single
binary input in the three phases. It also evaluates the alarm status logic and
generates the outputs.

Similarly, for phase L2 and phase L3, the alarm status are set. The information for
all the ten inputs in three-phases are divided into two 32 bit outputs. Here, output 1
is designated as ALS1T5 and output 2 is designated as ALS6T10. The last two bits
in both outputs are unused.

Calculating alarm status bits for analog input signals GUID-BC10CFB6-4B39-4218-B134-0E5A55D1DD47 v1

Example for alarm status calculation for analog input signals 1-9:

Consider for any input x for phase n, if Warning (Low Warning/High Warning)
information is set, then:

[ 6·(x-1) + 2·(n-1) ]th bit position in alarm status output goes high.

If Alarm (Low Alarm/High Alarm) information needs to be set, then:

[ 6·(x-1) + 2·(n-1) +1 ]th bit position in alarm status output goes high.

ALS1T5 becomes 00110101011000110100101001011001 in binary, that is

895699545 in decimal.

During the bit packing, the 30th and 31st bits are not used (set as zero).

Similar procedure is carried out for ALS6T10

Calculating alarm status bits for binary input signals GUID-B16C1FEF-36F9-4ECB-9E5A-4331029DB904 v1

Example for alarm status calculation for binary input 10:

Table 230: Alarm status bits for binary input signals
Input in phase Alarm range Alarm status
L1 Warning is set to 01
L2 Alarm is set to 1000
L3 High Alarm is set to 100000

319
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

Hence the alarm status for binary input 10 is 101001. This gets bit packed in
ALS6T10 (in 24th to 29th bit position).

If none of these conditions are met (that is no warning or alarm), the bits are set to
0.

11.17.7.2 Hysteresis GUID-5C6220FD-69BC-4C82-99EA-0C54603F9A28 v1

Hysteresis is applied to prevent frequent toggling of alarms if the input signal

oscillates around the threshold by a small amount. The extent of the hysteresis zone
is defined by InpxHystAbsolute for each of the analog input signals x. This setting
applies equally to all enabled thresholds for that signal group.
• If the signal rises above one of the upper thresholds, the output will indicate
this condition until the signal drops below the level threshold minus hysteresis.
• If the signal drops below one of the lower thresholds, the output will indicate
this condition until the signal rises above the level threshold plus hysteresis.

This is demonstrated in Figure 119, showing an analog signal passing from Normal
range through High Warning, High Alarm, High Warning, Normal, Low Warning,
and back to Normal ranges. Hysteresis is indicated by arrows, and small circles
mark the points of output status change.

11.17.7.3 Circuit breaker operation capability GUID-57128495-A0F6-44AF-B938-CF0A07F1E0E9 v1

The operation capability of the circuit breaker can be determined by the binary
input signal levels for the three phases.

For any phase,

320
Technical Manual
1MRK 511 275-UEN A Section 11
Monitoring

• When the input signal is full level, the breaker can operate a full cycle of open-
close-open operation.
• When the input signal is medium level, the breaker can operate only a close
followed by an open operation.
• When the input signal is low level, the breaker operation is restricted to a
single open operation.
• When the input signal is absent, there cannot be a possible breaker operation.

Example, consider full level binary input signal (representing stored energy in the
drive) for phase L1, medium level signal for phase L2 and low level signal for
phase L3.
• Phase L1 has full level binary input signal. It implies that full spring charge is
available and the breaker can operate a complete cycle of open-close-open
operation.
• For phase L2, the full level binary signal is absent and only the medium level
binary input signal is high, it implies that sufficient spring charge is
unavailable for a full cycle operation. Hence the breaker can operate only a
close followed by an open operation.
• For phase L3, the spring charge is low, the breaker can operate only open
operation.
• When all input signals are absent in all three phases, there is no operation of
the circuit breaker possible.

In this case, the integer value of CBOPCAP3P is 131844 as defined in Table 231

Table 231 shows all possible combinations of circuit breaker operation for the three
phases with the corresponding output integer values.

11.18.2 Functionality GUID-95C5500E-1C42-455E-A3CC-831181DAFDBA v2

ACBMSCBR monitors the condition of a circuit breaker pole by measuring and

supervising its electrical and mechanical performance during opening and closing
operations. Accordingly, the measurements will be used to report and, if
configured, adaptively compensate for changes in the circuit breaker’s
performance, including optimizing the arcing time to avoid re-strikes/re-ignitions.

In controlled switching applications, ACBMSCBR assists SSCPOW in

determining the precise target phase angles. For this purpose, it evaluates
compensation values according to actual system frequency and voltage, circuit
breaker scatter characteristics, etc. so that switching transients due to mechanical
and electrical variations in CB operating parameters are minimized.

11.19.2 Functionality GUID-51251660-53CD-4FC6-97C2-BF907017265D v2

This function provides semi-automatic learning of the mechanical closing and

opening times of a circuit breaker's primary contacts and, optionally, auxiliary
contacts. In addition, logical wiring errors are detected and reported during the
learning process. This function learns the timing information of three phases of a
circuit breaker independently, each of which may have its individual drive. When a
switching command is received, it generates a request to SSCPOW function for
sending the commands to the circuit breaker poles, and acquires the changeover
times of the connected contacts accurately through precision binary inputs. The
user has an option to accept or reject the results of each operation. Accepted results
are averaged and are available for use in the controlled switching application.

For performing controlled switching and monitoring, the knowledge of status

changeover of primary contact’s mechanical touch/separation instants is of prime
importance. This information is required for determining the precise target
switching instant. While monitoring live switching operations, the timing
information of auxiliary contacts (NO/52a and NC/52b) is required for accurate
estimation of primary contact timing. During CB test mode, the function also
detects logical wiring errors. This function has the option to provide the other
functions with either the default setting values or the learnt values (if learning has
been performed at least once) at its output interfaces.

This function is used to acquire the primary contacts’ and optionally the auxiliary
contacts’ (NO/52a and NC/52b) timing information during CB test mode.
CBLEARN receives the switching commands from the user and releases time
staggered commands to the individual poles of the circuit breaker through
SSCPOW function block. From the status changeover instants of primary and
auxiliary contacts, CBLEARN calculates the switching times and detects command
errors and wiring errors. Typical expected sequences of contact changeover, in each
CB pole, are shown in Figure 122 and Figure 123.

CBLEARN can be activated from LHMI menu or by activating the CBTMD input.
Once this trigger goes high, CBLEARN enters the learning mode (the
LERACTIVE output becomes high) and it remains in this mode until FINISH or
ABORT inputs are activated. In learning mode, CBLEARN interacts closely with
the SSCPOW function block, as shown in Figure 122.

11.19.6.1 Command handling logic GUID-92B52B0F-1192-42C6-A011-167A2D06F8BD v1

CBLEARN receives the Open/Close command and releases separate commands

through SSCPOW function block to the three poles of the circuit breaker, as shown
in Figure 124. Circuit breaker pole L1 is operated first, then L2, and finally L3.
The time delay between poles is defined by the TimeOutAlarmDelay setting. It
ensures that no cross cable interference or wiring mix up between phases is present.

The function also detects static wiring errors, dynamic wiring errors and errors in
command execution. These are described below.

Static wiring errors

When static wiring errors are detected, operation of the circuit breaker is not
permitted until they are rectified. Static wiring errors are detected by a plausibility
algorithm as described below.

1. All 3 poles are either not open or closed simultaneously. If two poles are open
and one pole is closed, the pole that is closed will be declared to have an error
as it is not in agreement with the other two poles being open. The same applies
vice versa if two poles are closed and one pole is open.
2. For any phase, if the primary contact is open it expects NO/52a to be open and
NC/52b to be closed.
3. For any phase, if the primary contact is closed it expects NO/52a to be closed
and NC/52b to be open.

CBLEARN checks the position of the breaker from the primary and auxiliary
contacts. If the CB position of any phase has errors, the wiringError (WIERLX)
signal of the corresponding phase is activated. The observed wiring errors and the
corresponding error codes are shown in Table 241.

Dynamic wiring errors

Dynamic wiring errors are detected during the execution of the Open/Close
commands. For example: If the command is released to phase L1, CBLEARN
expects status changes of the primary and auxiliary contacts of phase L1 only. If no
status changeover is observed within a set period, it declares a time-out alarm and
dynamic wiring error in phase L1. The same is applied to detect wiring errors in
phases L2 and L3. If an Open or Close command is issued to one phase but status
changeovers are detected in another phase, CBLEARN issues a wiring error. Error
codes for different types of wiring errors are explained in Table 242.

Monitoring

During the command, if for any phase, errors are detected, learning
for the current operation is stopped and an emergency trip
(instantaneous trip command to all three poles simultaneously) is
issued. Identified errors are expected to be corrected before
proceeding.

Commands are accepted until CB test mode is excited by activating ABORT or

FINISH inputs.

11.19.6.2 Data acquisition logic GUID-45E90641-9FE7-4EA4-8B08-E2FCCB5EEEFC v1

After the command request has been sent to SSCPOW, this block receives the
actual command information sent to the circuit breaker from SSCPOW and waits
for the update of main and auxiliary contact information. Upon receiving this
information, the operating times can be evaluated.

11.19.6.3 Core logic GUID-3CE4E298-EC09-4F39-90D0-1E504EF87D87 v1

Core module is executed when data acquisition is successful following an open or

close command from SSCPOW. Once the appropriate timing information has been
evaluated for primary and auxiliary contacts, the core logic derives the actual
switching times from command to NO/52a, NC/52b and Primary contact
changeover, and makes them available on the outputs LONOTIMLX,
LONCTIMLX, LOPRITIMLX (where LX is L1, L2 L3). At the same time the
function increments the counter of operations performed.

If the acquired values are considered not to be correct, they can be discarded by
activating the REJLO input. Once the REJLO command is received, CBLEARN
discards the calculated temporary time values that correspond to the last operation
and decrements the number of operations performed counter.

The calculated switching times from the last operation are accepted implicitly, by
issuing a new switching command, or explicitly, by activating the ACPTLO input.
Once a new switching command or the ACPTLO signal is received, the accepted
values acquired thus far are averaged and presented at the outputs OPAVGNOLX,
OPAVGNCLX, OPAVGPRILX and CLAVGNOLX, CLAVGNCLX,
CLAVGPRILX for open and close respectively (where LX is L1, L2, or L3). If the
average values are found satisfactory, CB test mode can be completed and exited
by activating the FINISH input. Once FINISH is activated, CBLEARN exits CB
test mode. Only when AvgSetSel has been set to "setOpIsCalcAvgValues", the
average values are presented at the outputs OPTIMNOLx, OPTIMNCLx,
OPTIMPRILx and CLTIMNOLx, CLTIMNCLx, CLTIMPRILx for opening and
closing respectively (where Lx is L1, L2, or L3).

Change AvgSetSel to "setOpIsCalcAvgValues" only when CB test

mode has been completed successfully!

345
Technical Manual
Section 11 1MRK 511 275-UEN A
Monitoring

To avoid loss of the calculated average values, make sure to keep

the IED powered up for minimum 1 hour after completing CB test
mode.

CB test mode can be aborted at any stage of learning by activating the ABORT
input if the learning cannot be continued or the results are not satisfactory. In such
a case the function discards the currently calculated average values and retains the
set average outputs to either the previously learnt values (if available) or user-set
values, depending on AvgSetSel setting.

Depending on the Mode selection, the function calculates the operating times of the
auxiliary and primary contacts for the open command or close command or both.
For example, if Mode is set to “Open only”, only the operating times corresponding
to the open command are evaluated and are updated at the corresponding average
outputs. The average outputs for the close command follow the previously learnt
values if available or user-set values otherwise.

Successful and unsuccessful operations GUID-527381B8-513D-42A2-B08F-A2781D90946F v1

An operation is declared successful if status changes of auxiliary and primary

contacts are detected for all the phase commands within a set time of
TimeOutAlarmDelay after CMDOPX (for open operation) or CMDCLX (for close
operation) information has been received from SSCPOW. Otherwise the operation
is declared as failed. This is indicated externally on the LOPSUC, LCLSUC and
LOPFAIL, LCLFAIL outputs, respectively, as shown in Table 246 and Table 247.

12.1.2 Functionality D0E7194T201305151403 v2

The IED supports the communication protocol IEC 61850-8-1. All operational
information and controls are available through this protocol.

The IED is equipped with optical Ethernet rear port(s) for the substation
communication standard IEC 61850-8-1. IEC 61850-8-1 protocol allows intelligent
electrical devices (IEDs) from different vendors to exchange information and
simplifies system engineering. Peer-to-peer communication according to GOOSE
is part of the standard. Disturbance files downloading is provided.

Disturbance files (waveform files in Switchsync PWC600 terminology) are

accessed using the IEC 61850-8-1 protocol. Disturbance files are also available to
any Ethernet based application via FTP in the standard Comtrade format. Further,
the IED can send and receive binary values, double point values and measured
values (for example from MMXU functions), together with their quality bit, using
the IEC 61850-8-1 GOOSE profile. The IED meets the GOOSE performance
requirements for tripping applications in substations, as defined by the IEC 61850
standard. The IED interoperates with other IEC 61850-compliant IEDs and
systems, and simultaneously reports events to five different clients on the IEC
61850 station bus.

The Denial of Service functions DOSLAN1 and DOSFRNT are included to limit
the inbound network traffic. The communication can thus never compromise the
primary functionality of the IED.

The event system has a rate limiter to reduce CPU load. The event channel has a
quota of 10 events/second after the initial 30 events/second. If the quota is
exceeded the event channel transmission is blocked until the event changes is
below the quota, no event is lost.

Station communication

All communication connectors, except for the front port connector, are placed on
integrated communication modules. The IED is connected to Ethernet-based
communication systems via the fibre-optic multimode LC connector(s) (100BASE-

The IED supports SNTP and IRIG-B time synchronization methods with a time-
stamping accuracy of ±1 ms.

12.7 IEC 61850-9-2(LE) merging unit

12.7.1 Introduction GUID-BA744DF4-1854-4E69-BDF2-1A569DE290BE v2

The IEC 61850-9-2 standard defines a process bus for transmitting sampled values
of primary voltage and current signals over Ethernet. “LE” (Light Edition) is a
commonly agreed implementation guideline, which defines a practical subset of
IEC 61850-9-2 to allow straightforward implementation and application.

IEC 61850-9-2(LE) defines a logical device Merging Unit (MU). A MU collects up

to four individual current and four voltage signals and merges them into a single
data stream.

In the Switchsync PWC600 IED, sampled values streams from up to four MUs are
received on the LAN2 A port of the communication interface module COM03. The
application can access them as outputs of the MUx_4I_4U function blocks (x = 1…
4) and use them in the same manner as analog inputs on a TRM or AIM card.

12.7.6 Operation principle GUID-1318F925-300F-418F-9526-BD8540DFF22E v1

A merging unit (MU) gathers sampled values of primary current and voltage
signals from instrument transformers, electronic transducers, or both. The gathered
data are transmitted to subscribers over the process bus, utilizing a process bus
according to the IEC 61850-9-2(LE) specification.

The IED communicates with the MUs over the process bus via the LAN2 A port
(X3) of the communication interface module. Only data streams sampled at 80
samples/cycle are accepted. In ACT, the MU appears as a function block (unlike an
analog input module).

12.7.6.1 Signal identification GUID-35A49B49-EA89-40A0-97B3-CA9BCB3A02AE v1

Up to four logical MUs can be connected to an IED on a single physical interface.

The data streams from individual MUs are distinguished by the SVId (Sampled

364
Technical Manual
1MRK 511 275-UEN A Section 12
Station communication

Values Identification) setting, which must be set identical to the MsvID data
attribute of MSVCB01 in the MU.

The IEC 61850-9-2(LE) guideline specifies that the value of SVId shall comprise
10 characters and follow the convention “xxxxMUnn01”. The portions “xxxx” and
“nn” can be substituted by user-defined strings, whereas “MU” and “01” are fixed
and should not be changed. However, the MUx_4I_4U function blocks will work
correctly also with less restrictive values of SVId.

The SmplGrp parameter is not used in the PWC600 implementation, keep it at

default value 0.

Within a MU1_4I_4U function block, the assignment of sampled values streams (4

currents, 4 voltages) is fixed, as provided by the MU.

12.7.6.2 Time synchronization GUID-BEF65E7B-EB03-4E43-8EC5-2FF6824BA24C v1

Sampled values received over the process bus are time stamped. For synchronizing
the signal processing in the IED to the incoming data stream, an external 1PPS
signal shall be provided on the PPS Rx port (X10) of the communication interface
module. Accuracy shall be class T4 (±4 µs) or better.

Preferably, a GPS based clock source is used as master for generating a station-
wide 1PPS clock for all merging units and receiving IEDs. This is particularly
important when an IED may receive sampled values from more than one MU. Only
if any IED is connected to just one MU then the MU may be used as clock master
for the receiving IED(s).

The SynchMode parameter determines handling of the synchronization information

in the datastream:
• When set to "NoSynch" it will not check the SmpSynch flag.
• When set to "Operation" it will always check the SmpSynch flag.
• "Init" should not be used.

See TIMESYNCHGEN for further information on time synchronization.

12.7.6.3 Alarm signals GUID-1DC11181-BDA8-4AF2-AC8B-EE57D22C4C13 v1

Each MU function block has five binary alarm signal outputs.

• MUDATA: Indicates when sample sequence needs to be realigned, that is, the
application needs to be restarted soon. The signal is raised for 2 seconds before
the application is restarted.
• SYNCH: Indicates that the internal time synchronization quality is out of the
set value from parameter TIMESYNCHGEN.syncAccLevel (“1 μs”, “4 μs” or
“unspecified”) and the parameter TIMESYNCHGEN.AppSynch is set to

365
Technical Manual
Section 12 1MRK 511 275-UEN A
Station communication

“Synch”. If TIMESYNCHGEN.AppSynch is set to “NoSynch”, the SYNCH

output never goes high.
• SMPLT: Indicates that more than one sample has been lost or marked as
invalid, overflown or failed and the sample has thereafter been substituted.
• SYNMU: Indicates that the MU connected is not synchronized. Received from
SmpSynch flag in datastream. No IED setting affects this signal.
• TSTMD: Indicates that the MU connected is in “Test Mode”. Received from
Test flag in datastream. No IED setting affects this signal.

In case of communication problems, all analog outputs will be

forced to 0.0.

Connect the binary output signals, except for TSTMD, to the

BLKSYNSW input of the SSCPOW function, for blocking
controlled switching operations in case of communication
problems. See the section on Controlled Switching & Monitoring.

12.7.6.4 Accuracy of power measurement functions GUID-2521102E-1229-4796-A073-83F11C8D04F0 v1

The power measurement functions (CVMMXN, CMMXU, VMMXU and

VNMMXU) contain correction factors to account for the nonlinearity in the input
circuits, mainly in the input transformers, when using direct analog connection to
the IED.

The IED uses the same correction factors when feeding the IED with analog
signals over IEC 61850-9-2(LE). Since the signals via IEC 61850-9-2(LE) are not
subjected to the same nonlinearity errors, this causes an inaccuracy in the measured
values.

For voltage signals, the correction factors are less than 0.05% of the measured
value and no angle compensation, hence the impact on the reported value can be
ignored.

For current signals, the correction factors cause a significant impact on the reported
values at low currents. The correction factors are +2.4% and -3.6 degrees at signal
levels below 5% of the set base current, +0.6% and -1.12 degrees at signal level
30% of the set base current and 0% and -0.44 degrees at signal levels above 100%
of the set base current. Between the calibration points 5%, 30% and 100% of the
set base current, linear interpolation is used.

The PRPSTATUS function has no user settings.

Redundant station bus communication is configured in the LHMI under Main

where Operation mode, IPAddress and IPMask can be entered.

12.8.6 Operation principle D0E8122T201305151403 v1

The redundant station bus communication is configured using the local HMI, Main
Menu/Configuration/Communication/TCP-IP configuation/ETHLAN1_AB.
The settings are also visible in PST in PCM600.

Redundant communication runs in parallel, meaning that the same data package is
transmitted on both channels simultaneously. The received package identity from
one channel is compared with the data package identity from the other channel. If
the identity is the same, the last package is discarded.

PRPSTATUS supervises redundant communication on the two channels. If no data

package has been received on one or both channels within the last 10 s, the output
LAN1-A and/or LAN1-B are set to indicate error.

13.1.4 Operation principle

D0E7094T201305151403 v1

The self-supervision operates continuously and includes:

• Normal micro-processor watchdog function.

• Checking of digitized measuring signals.
• Other alarms, for example hardware and time synchronization.

The SELFSUPEVLST function status can be monitored from the local HMI, from
the Event Viewer in PCM600 or from a SMS/SCS system.

Under the Diagnostics menu in the local HMI the present information from the
self-supervision function can be reviewed. The information can be found under
Main menu/Diagnostics/Internal events or Main menu/Diagnostics/IED status/
General. The information from the self-supervision function is also available in the
Event Viewer in PCM600. Both events from the Event list and the internal events
are listed in time consecutive order in the Event Viewer.

A self-supervision summary can be obtained by means of the potential free change-

over alarm contact IRF (Internal Fail) located on the power supply module. This
output contact is activated (where there is no fault) and deactivated (where there is
a fault) by the Internal Fail signal, see Figure 135. The software watchdog timeout
and the undervoltage detection of the PSM will deactivate the contact as well.

Some signals are available from the INTERRSIG function block. The signals from
INTERRSIG function block are sent as events to the station level of the control
system. The signals from the INTERRSIG function block can also be connected to
binary outputs for signalization via output relays or they can be used as conditions
for other functions if required/desired.

Individual error signals from I/O modules can be obtained from respective module
in the Signal Matrix tool. Error signals from time synchronization can be obtained
from the time synchronization block INTERRSIG.

13.1.4.1 Internal signals D0E7081T201305151403 v1

SELFSUPEVLST function provides several status signals, that tells about the
condition of the IED. As they provide information about the internal status of the
IED, they are also called internal signals. The internal signals can be divided into
two groups.

Figure 137: Simplified drawing of A/D converter for the IED.

The technique to split the analog input signal into two A/D converter(s) with
different amplification makes it possible to supervise the A/D converters under
normal conditions where the signals from the two A/D converters should be

Basic IED functions

identical. An alarm is given if the signals are out of the boundaries. Another benefit
is that it improves the dynamic performance of the A/D conversion.

The self-supervision of the A/D conversion is controlled by the ADx_Controller

function. One of the tasks for the controller is to perform a validation of the input
signals. The ADx_Controller function is included in all IEDs equipped with an
analog input module. This is done in a validation filter which has mainly two
objects: First is the validation part that checks that the A/D conversion seems to
work as expected. Secondly, the filter chooses which of the two signals shall be
sent to the CPU, that is the signal that has the most suitable signal level, the
ADx_LO or the 16 times higher ADx_HI.

When the signal is within measurable limits on both channels, a direct comparison
of the two A/D converter channels can be performed. If the validation fails, the
CPU will be informed and an alarm will be given for A/D converter failure.

The ADx_Controller also supervises other parts of the A/D converter.

Time definitions D0E6680T201305151403 v1

The error of a clock is the difference between the actual time of the clock, and the
time the clock is intended to have. Clock accuracy indicates the increase in error,
that is, the time gained or lost by the clock. A disciplined clock knows its own
faults and tries to compensate for them.

Synchronization principle D0E6681T201305151403 v1

From a general point of view synchronization can be seen as a hierarchical

structure. A function is synchronized from a higher level and provides
synchronization to lower levels.

IEC09000342-1-en.vsd
D0E12044T201305151403 V1 EN-US

Figure 139: Synchronization principle

A function is said to be synchronized when it periodically receives synchronization

messages from a higher level. As the level decreases, the accuracy of the

385
Technical Manual
Section 13 1MRK 511 275-UEN A
Basic IED functions

synchronization decreases as well. A function can have several potential sources of

synchronization, with different maximum errors. This gives the function the
possibility to choose the source with the best quality, and to adjust its internal clock
after this source. The maximum error of a clock can be defined as:

• The maximum error of the last used synchronization message

• The time since the last used synchronization message
• The rate accuracy of the internal clock in the function.

13.2.9.2 Real-time clock (RTC) operation D0E6655T201305151403 v1

The IED has a built-in real-time clock (RTC) with a resolution of one second. The
clock has a built-in calendar that handles leap years through 2038.

Real-time clock at power off D0E6661T201305151403 v1

During power off, the system time in the IED is kept by a capacitor-backed real-
time clock that will provide 35 ppm accuracy for 5 days. This means that if the
power is off, the time in the IED may drift with 3 seconds per day, during 5 days,
and after this time the time will be lost completely.

Real-time clock at startup D0E6662T201305151403 v1

At IED startup, the internal time is free running. If the RTC is still alive since the
last up time, the time in the IED will be accurate (may drift 35 ppm), but if the
RTC power has been lost during power off (will happen after 5 days), the IED time
will start at 1970-01-01.

Time synchronization startup procedure D0E6678T201305151403 v1

Coarse time synchronization is used to set the time on the very first message and if
any message has an offset of more than ten seconds. If no FineSyncSource is given,
the CoarseSyncSource is used to synchronize the time.

Fine time synchronization is used to set the time on the first message after a time
reset or if the source may always set the fine time, and the source gives a large
offset towards the IED time. After this, the time is used to synchronize the time
after a spike filter, that is, if the source glitches momentarily or there is a
momentary error, this is neglected. FineSyncSource that may always set the time is
only IRIG-B.

It is not recommended to use SNTP as both fine and coarse synchronization source,
as some clocks sometimes send out a bad message. For example, Arbiter clocks
sometimes send out a "zero-time message", which if SNTP is set as coarse
synchronization source (with or without SNTP as fine synchronization source)
leads to a jump to "2036-02-07 06:28" and back. In all cases, except for
demonstration, it is recommended to use SNTP as FineSynchSource only.

386
Technical Manual
1MRK 511 275-UEN A Section 13
Basic IED functions

Rate accuracy D0E6684T201305151403 v1

In the IED, the rate accuracy at cold start is 100 ppm but if the IED is synchronized
for a while, the rate accuracy is approximately 1 ppm if the surrounding
temperature is constant. Normally, it takes 20 minutes to reach full accuracy.

Time-out on synchronization sources D0E6685T201305151403 v1

All synchronization interfaces has a time-out and a configured interface must

receive time-messages regularly in order not to give an error signal (TSYNCERR).
Normally, the time-out is set so that one message can be lost without getting a
TSYNCERR, but if more than one message is lost, a TSYNCERR is given.

13.2.9.3 Synchronization options D0E6637T201305151403 v1

Two main options of external time synchronization are available. The

synchronization message is applied either via any of the communication ports of
the IED as a telegram message including date and time or via IRIG-B.

Synchronization via SNTP D0E6653T201305151403 v1

SNTP provides a ping-pong method of synchronization. A message is sent from an

IED to an SNTP server, and the SNTP server returns the message after filling in a
reception time and a transmission time. SNTP operates via the normal Ethernet
network that connects IEDs via IEC 61850 station bus. For SNTP to operate
properly, there must be an SNTP server present, preferably in the same station. The
SNTP synchronization provides an accuracy that gives +/- 1 ms accuracy for binary
inputs. The IED itself can be set as an SNTP-time server.

SNTP provides complete time-information and can be used as both fine and coarse
time synch source. However shall SNTP normally be used as fine synch only. The
only reason to use SNTP as coarse synch is in combination with PPS as fine
source. The combination SNTP as both fine and coarse source shall not be used.

SNTP server requirements D0E6710T201305151403 v1

The SNTP server to be used is connected to the local network, that is not more than
4-5 switches or routers away from the IED. The SNTP server is dedicated for its
task, or at least equipped with a real-time operating system, that is not a PC with
SNTP server software. The SNTP server should be stable, that is, either
synchronized from a stable source like GPS, or local without synchronization.
Using a local SNTP server without synchronization as primary or secondary server
in a redundant configuration is not recommended.

Synchronization via IRIG-B D0E6636T201305151403 v1

IRIG-B is a protocol used only for time synchronization. A clock can provide local
time of the year in this format. The “B” in IRIG-B states that 100 bits per second
are transmitted, and the message is sent every second. After IRIG-B there numbers
stating if and how the signal is modulated and the information transmitted.

To receive IRIG-B there are one dedicated connector for the IRIG-B port. IRIG-B
00x messages can be supplied via the galvanic interface, where x (in 00x) means a
number in the range of 1-7.

387
Technical Manual
Section 13 1MRK 511 275-UEN A
Basic IED functions

If the x in 00x is 4, 5, 6 or 7, the time message from IRIG-B contains information

of the year. If x is 0, 1, 2 or 3, the information contains only the time within the
year, and year information has to come from the tool or local HMI.

The IRIG-B input also takes care of IEEE1344 messages that are sent by IRIG-B
clocks, as IRIG-B previously did not have any year information. IEEE1344 is
compatible with IRIG-B and contains year information and information of the
time-zone.

It is recommended to use IEEE 1344 for supplying time information to the IRIG-B
module. In this case, send also the local time in the messages.

Synchronization via process bus IEC 61850-9-2LE GUID-684E5B3A-AF6B-4BDC-966A-BB5B3AAC4280 v1

An optical PPS signal can be used for the time synchronisation of the process bus
communication (IEC 61850-9-2LE protocol). This signal should emanate either
from the external GPS clock or from the merging unit.

13.3.2 Functionality D0E7161T201305151403 v1

When the Test mode functionality TESTMODE is activated, all the functions in the
IED are automatically blocked. Activated TESTMODE is indicating by a flashing
yellow LED on the local HMI. It is then possible to unblock every function(s)
individually from the local HMI to perform required tests.

388
Technical Manual
1MRK 511 275-UEN A Section 13
Basic IED functions

When leaving TESTMODE, all blockings are removed and the IED resumes
normal operation. However, if during TESTMODE operation, power is removed
and later restored, the IED will remain in TESTMODE with the same protection
functions blocked or unblocked as before the power was removed. All testing will
be done with actually set and configured values within the IED. No settings will be
changed, thus mistakes are avoided.

Forcing of binary output signals is only possible when the IED is in test mode.

13.3.6 Operation principle D0E6992T201305151403 v1

D0E7120T201305151403 v1

Put the IED into test mode to test functions in the IED. Set the IED in test mode by

• configuration, activating the input SIGNAL on the function block

TESTMODE.
• setting TestMode to On in the local HMI, under Main menu/Tests/IED test
mode/1:TESTMODE.

While the IED is in test mode, the output ACTIVE of the function block
TESTMODE is activated. The outputs of the function block TESTMODE shows
the cause of the “Test mode: being in On” state. If the input from the configuration
(OUTPUT signal is activated) or setting from local HMI (SETTING signal is
activated).

While the IED is in test mode, the yellow START LED will flash and all functions
are blocked. Any function can be unblocked individually regarding functionality
and event signalling.

Forcing of binary output signals is only possible when the IED is in test mode.
D0E7113T201305151403 v1

Most of the functions in the IED can individually be blocked by means of settings
from the local HMI. To enable these blockings the IED must be set in test mode
(output ACTIVE is activated). When leaving the test mode, and returning to
normal operation, these blockings are disabled and everything is set back to normal
operation. All testing will be done with actually set and configured parameter
values within the IED. No settings will be changed, thus no mistakes are possible.

The blocked functions will still be blocked next time entering the test mode, if the
blockings were not reset. The released function will return to blocked state if test
mode is set to off.

The blocking of a function concerns all output signals from the actual function, so
no outputs will be activated.

When a binary input is used to set the IED in test mode and a
parameter, that requires restart of the application, is changed, the
IED will re-enter test mode and all functions will be blocked, also
functions that were unblocked before the change. During the re-

390
Technical Manual
1MRK 511 275-UEN A Section 13
Basic IED functions

entering to test mode, all functions will be temporarily unblocked

for a short time, which might lead to unwanted operations. This is
only valid if the IED is set in TEST mode by a binary input, not by
local HMI.

The TESTMODE function block might be used to automatically block functions

when a test handle is inserted in a test switch. A contact in the test switch (RTXP24
contact 29-30) can supply a binary input which in turn is configured to the
TESTMODE function block.

Each of the functions includes the blocking from the TESTMODE function block.

The functions can also be blocked from sending events over IEC 61850 station bus
to prevent filling station and SCADA databases with test events, for example
during a commissioning or maintenance test.

13.4.2 Functionality D0E6765T201305151403 v1

Change lock function CHNGLCK is used to block further changes to the IED
configuration and settings once the commissioning is complete. The purpose is to
block inadvertent IED configuration changes beyond a certain point in time.

The change lock function activation is normally connected to a binary input.

D0E6913T201305151403 v1

When CHNGLCK has a logical one on its input, then all attempts to modify the
IED configuration and setting will be denied and the message "Error: Changes
blocked" will be displayed on the local HMI; in PCM600 the message will be
"Operation denied by active ChangeLock". The CHNGLCK function should be
configured so that it is controlled by a signal from a binary input card. This
guarantees that by setting that signal to a logical zero, CHNGLCK is deactivated. If
any logic is included in the signal path to the CHNGLCK input, that logic must be
designed so that it cannot permanently issue a logical one to the CHNGLCK input.
If such a situation would occur in spite of these precautions, then please contact the
local ABB representative for remedial action.

13.8 Signal matrix for analog inputs SMAI

13.8.1 Functionality D0E8610T201305151403 v1

Signal matrix for analog inputs function (SMAI), also known as the preprocessor
function, processes the analog signals connected to it and gives information about
all aspects of the analog signals connected, like the RMS value, phase angle,
frequency, harmonic content, sequence components and so on. This information is
then used by the respective functions in ACT (for example protection,
measurement or monitoring).

The SMAI function is used within PCM600 in direct relation with the Signal
Matrix tool or the Application Configuration tool.

In the Switchsync PWC600 pre-configuration, all analog inputs to

SMAI function blocks are routed through SRCSELECT function
blocks. This is to enable selection of input signal sources either
from TRM or IEC 61850-9-2(LE) merging units, through a setting.

13.8.6 Operation principle D0E8595T201305151403 v1

Every SMAI can receive four analog signals (three phases and one neutral value),
either voltage or current. The AnalogInputType setting should be set according to
the input connected. The signal received by SMAI is processed internally to obtain
244 different electrical parameters, for example RMS value, peak-to-peak,
frequency and so on. The activation of BLOCK input resets all outputs to 0.

SMAI_80 does all the calculation based on nominal 80 samples per line frequency
period, this gives a sample frequency of 4 kHz at 50 Hz nominal line frequency and
4.8 kHz at 60 Hz nominal line frequency.

The output signals AI1...AI4 in SMAI_80_x function block are direct outputs of
the connected input signals GRPxL1, GRPxL2, GRPxL3 and GRPxN. GRPxN is
always the neutral current. If GRPxN is not connected, the output AI4 is zero. The
AIN output is the calculated residual quantity, obtained as a sum of inputs
GRPxL1, GRPxL2 and GRPxL3 but is equal to output AI4 if GRPxN is connected.

399
Technical Manual
Section 13 1MRK 511 275-UEN A
Basic IED functions

The output signals AI1, AI2, AI3 and AIN are normally connected to the analog
disturbance recorder.

The SMAI function block always calculates the residual quantities

in case only the three phases (Ph-N) are connected (GRPxN input
not used).

The output signal AI3P in the SMAI function block is a group output signal
containing all processed electrical information from inputs GRPxL1, GRPxL2,
GRPxL3 and GRPxN. Applications with a few exceptions shall always be
connected to AI3P.

The input signal REVROT is used to reverse the phase order.

A few points need to be ensured for SMAI to process the analog signal correctly.
• It is not mandatory to connect all the inputs of SMAI function. However, it is
very important that same set of three phase analog signals should be connected
to one SMAI function.
• The sequence of input connected to SMAI function inputs GRPxL1, GRPxL2,
GRPxL3 and GRPxN should normally represent phase L1, phase L2, phase L3
and neutral currents respectively.
• It is possible to connect analog signals available as Ph-N or Ph-Ph to SMAI.
ConnectionType should be set according to the input connected.
• If the GRPxN input is not connected and all three phase-to-earth inputs are
connected, SMAI calculates the neutral input on its own and it is available at
the AI3P and AIN outputs. It is necessary that the ConnectionType should be
set to Ph-N.
• If any two phase-to-earth inputs and neutral currents are connected, SMAI
calculates the remaining third phase-to-neutral input on its own and it is
available at the AI3P output. It is necessary that the ConnectionType should be
set to Ph-N.
• If any two phase-to-phase inputs are connected, SMAI calculates the
remaining third phase-to-phase input on its own. It is necessary that the
ConnectionType should be set to Ph-Ph.
• All three inputs GRPxLx should be connected to SMAI for calculating
sequence components for ConnectionType set to Ph-N.
• At least two inputs GRPxLx should be connected to SMAI for calculating the
positive and negative sequence component for ConnectionType set to Ph-Ph.
Calculation of zero sequence requires GRPxN input to be connected.
• Negation setting inverts (reverse) the polarity of the analog input signal.

Frequency adaptivity

SMAI function performs DFT calculations for obtaining various electrical

parameters. DFT uses some reference frequency for performing calculations. For
most of the cases, these calculations are done using a fixed DFT reference based on
system frequency. However, if the frequency of the network is expected to vary
more than 2 Hz from the nominal frequency, more accurate DFT results can be

400
Technical Manual
1MRK 511 275-UEN A Section 13
Basic IED functions

obtained if the adaptive DFT is used. This means that the frequency of the network
is tracked and the DFT calculation is adapted according to that.

DFTRefExtOut and DFTReference need to be set appropriately for adaptive DFT

calculations.

DFTRefExtOut: Setting valid only for the instance of function block SMAI_80_1.
It decides the reference block for external output SPFCOUT.

DFTReference: Reference DFT for the block. This setting decides DFT reference
for DFT calculations. DFTReference set to InternalDFTRef uses fixed DFT
reference based on the set system frequency. DFTReference set to DFTRefGrpX
uses DFT reference from the selected group block, when own group selected
adaptive DFT reference will be used based on the calculated signal frequency from
own group. DFTReference set to External DFT Ref will use reference based on
input signal DFTSPFC.

Settings DFTRefExtOut and DFTReference shall be set to default

value InternalDFTRef if no VT inputs are available. However, if it
is necessary to use frequency adaptive DFT (DFTReference set to
other than default, referring current measuring SMAI) when no
voltages are available, note that the MinValFreqMeas setting is still
set in reference to UBase (of the selected GBASVAL group). This
means that the minimum level for the current amplitude is based on
UBase. For example, if UBase is 20000, the resulting minimum
amplitude for current is 20000 * 10% = 2000.

MinValFreqMeas: The minimum value of the voltage for which the frequency is
calculated, expressed as percent of the voltage in the selected Global Base voltage
group (GlobalBaseSel).

consists of values for current, voltage and apparent power and it is possible to have

This is an advantage since all applicable functions in the IED use a single source of
base values. This facilitates consistency throughout the IED and also facilitates a
single point for updating values when necessary.

Each applicable function in the IED has a parameter, GlobalBaseSel, defining one

The IED users can be created, deleted and edited only with the IED User
Management within PCM600. The user can only LogOn or LogOff on the local
HMI on the IED, there are no users, groups or functions that can be defined on
local HMI.

Only characters A - Z, a - z and 0 - 9 should be used in user names

and passwords.
The maximum of characters in a password is 12.

At least one user must be included in the UserAdministrator group

to be able to write users, created in PCM600, to IED.

13.10.4.1 Authorization handling in the IED D0E7206T201305151403 v1

At delivery the default user is the SuperUser. No Log on is required to operate the
IED until a user has been created with the IED User Management.

Once a user is created and written to the IED, that user can perform a Log on, using
the password assigned in the tool. Then the default user will be Guest.

If there is no user created, an attempt to log on will display a message box: “No
user defined!”

If one user leaves the IED without logging off, then after the timeout (set in Main
menu/Configuration/HMI/Screen/SCREEN:1) elapses, the IED returns to Guest
state, when only reading is possible. By factory default, the display timeout is set to
60 minutes.

If one or more users are created with the IED User Management and written to the
IED, then, when a user attempts a Log on by pressing the key or when the user
attempts to perform an operation that is password protected, the Log on window
opens.

The cursor is focused on the User identity field, so upon pressing the key, one
can change the user name, by browsing the list of users, with the “up” and “down”
arrows. After choosing the right user name, the user must press the key again.
When it comes to password, upon pressing the key, the following characters
will show up: “✳✳✳✳✳✳✳✳”. The user must scroll for every letter in the
password. After all the letters are introduced (passwords are case sensitive) choose
OK and press the key again.

At successful Log on, the local HMI shows the new user name in the status bar at
the bottom of the LCD. If the Log on is OK, when required to change for example
a password protected setting, the local HMI returns to the actual setting folder. If
the Log on has failed, an "Error Access Denied" message opens. If a user enters an

404
Technical Manual
1MRK 511 275-UEN A Section 13

incorrect password three times, that user will be blocked for ten minutes before a
new attempt to log in can be performed. The user will be blocked from logging in,
both from the local HMI and PCM600. However, other users are to log in during
this period.

13.12.2 Functionality D0E7390T201305151403 v1

The FTP Client defaults to the best possible security mode when trying to negotiate
with SSL.

The automatic negotiation mode acts on port number and server features. It tries to
immediately activate implicit SSL if the specified port is 990. If the specified port
is any other, it tries to negotiate with explicit SSL via AUTH SSL/TLS.

Using FTP without SSL encryption gives the FTP client reduced capabilities. This
mode is only for accessing disturbance recorder data from the IED.

If normal FTP is required to read out disturbance recordings, create

a specific account for this purpose with rights only to do File
transfer. The password of this user will be exposed in clear text on
the wire.

13.14.1 Functionality D0E7215T201305151403 v1

The Denial of service functions (DOSLAN1 and DOSFRNT) are designed to limit
overload on the IED produced by heavy Ethernet network traffic. The
communication facilities must not be allowed to compromise the primary
functionality of the device. All inbound network traffic will be quota controlled so
that too heavy network loads can be controlled. Heavy network load might for
instance be the result of malfunctioning equipment connected to the network.

13.15.2 Functionality GUID-2FA7F39C-76E0-4B03-B68F-E49A61FA6C6E v2

Switchsync PWC600 is supplied with a pre-configuration that can be customized to

most applications by settings entered in Switchsync Setting Tool (SST). The
SRCSELECT function allows selecting the source of an analog (voltage or current)
signal from TRM (hardware based) or MU (software based) by settings. Flexibility
of selection of the input source from all the MUs (that is, four MUs) and TRM (that
is, two TRMs) sources modeled as three-phase + neutral inputs eliminates the need
for modifications in ACT or SMT. A SRCSELECT function block is placed
between TRM or MU outputs and SMAI inputs.

There are eight sets of input available in the function. Each set is modeled as the
three-phase +neutral input. For each MU, the function has five binary status inputs.

411
Technical Manual
Section 13 1MRK 511 275-UEN A
Basic IED functions

The selection needs to be done for the status signals of MU from which the data is
subscribed. TRM signals can be connected to any of the eight input phase group.

Figure 149: Source selector application

Figure 149 depicts the source selector embedded in an application. When

InputSelect is set to "INPUT1", the INPUT1 channel link strings are passed to the
pre-processing component, and so forth. Based on that link, the pre-procesing
component fetches the data from the particular channel.

The IED supports four IEC 61850- 9-2 (LE) merging unit streams, wherein each
stream has four sets of current and voltage signals. In a hybrid configuration, the
current and voltage can be either from a conventional CT/VT (connection through
TRM) or through the IEC 61850- 9-2 (LE) MU. The eight input groups are
provided per instance for the selection, out of which the last four input groups can
be connected to the merging unit signals, as there are diagnostic status signals that
need to be selected and provided as an output from the function.

The input groups are named INPUT1-x to INPUT8-x and each group supports four
analog inputs. INPUT5-x to INPUT8-x additionally support the diagnostic binary
status signals from a merging unit (see description of MU_4I_4U). If any of
INPUT1 through INPUT4 is selected, the diagnostic outputs assume default value
0.

13.16.3 Operation principle GUID-D9F399C0-CD50-4E85-950F-FF4142317132 v1

For accessing the IED using a web browser, WEBSERVER works as an interface
function to accept requests and send data. The actual webpages to be displayed are
defined by HTML files stored in the IED. WEBSERVER interacts with the
authority system in the IED to validate user permissions.

Access to the IED from a web browser can be disabled by setting Operation to
“Off”.

It is possible to change IED parameters and settings through Web HMI. This
feature can be disabled by setting WriteMode to “Writing disabled”.

From a security point of view, it is desirable to terminate a browser session if the

user has been idle for some duration. This duration can be set by SessionTimeout.

The IED has two physical ports through which it can be accessed using web
browser. Allowed access can be configured using the Port setting. The options are
described in the table below.

14.3.2 IRF D0E8362T201305151403 v3

The IRF contact functions as a change-over output contact for the self-supervision
system of the IED. Under normal operating conditions, the IED is energized and
one of the two contacts is closed. When a fault is detected by the self-supervision
system or the auxiliary voltage is disconnected, the closed contact drops off and the
other contact closes.

Each signal connector terminal is connected with one 0.5...2.5 mm2 wire or with
two 0.5...1.0 mm2 wires.

14.4 Communication interfaces D0E8365T201305151403 v2

The IED's LHMI is provided with an RJ-45 connector. This interface is intended
for configuration and setting purposes.

Station bus and process bus communication runs on the communication module via
the optical interfaces (LC Ethernet connectors) on the rear panel. If both are used,
the process bus shall run as a separate network from the station bus to prevent
interference of control data with the sampled values stream.

424
Technical Manual
1MRK 511 275-UEN A Section 14
IED physical connections

Rear communication via the X8/EIA-485/IRIG-B connector uses a communication

module with the galvanic EIA-485 serial connection.

The HMI connector X0 and the serial interface X9 are not used in Switchsync
PWC600.

14.4.1 Ethernet RJ-45 front connection D0E8363T201305151403 v2

The IED's LHMI is provided with an RJ-45 connector designed for point-to-point
use. This interface is intended for configuration and setting purposes. The interface
on the PC has to be configured in a way that it obtains the IP address automatically
if the DHCP server is enabled in LHMI. The DHCP server inside the IED can be
activated for the front interface only.

Usually this port is used only for temporary connection, thus no permanent wiring
is required. Events, setting values and all input data such as operation records and
waveform records can be read via the front communication port.

Only one of the possible clients can be used for parametrization at a time.

• PCM600
• LHMI
• WHMI

The default IP address of the IED through this port is 10.1.150.3.

The front port supports TCP/IP protocol. A standard Ethernet CAT 5 crossover
cable with RJ-45 connector is used with the front port.

14.4.2 Station communication rear connection D0E8366T201305151403 v2

The default IP address of the IED through the rear Ethernet port is 192.168.1.10.
The physical connector is X1/LAN1 A. The communication speed is 100 Mbps for
the 100BASE-FX LC interface.

For redundant communication, X1/LAN1 A and X2/LAN1 B can be used.

Serial communication can be used via optical connection in star topology.

Connector type is glass (ST connector). Connection's idle state is indicated either
with light on or light off. The physical connector is X9/Rx,Tx.

14.4.4 EIA-485 serial rear connection D0E8368T201305151403 v2

The communication module follows the EIA-485 standard and is intended to be

used in multi-point communication.

14.4.5 Process bus rear connection GUID-60053C7B-4AD3-4DEC-9C47-BD2C2479516E v2

Switchsync PWC600 can receive digital sampled values (voltage and/or current)
via IEC 61850-9-2(LE) on its X3/LAN2 A interface. Up to four logical merging
units can be connected, which are distinguished by their sampled values ID (svID).
The specifications of X3 are identical to X1 and X2.

Hardware synchronization of the sampled values is achieved by a 1PPS signal

received on optical input X10. Time synchronization via SNTP or IRIG-B cannot
be used for this purpose.

426
Technical Manual
1MRK 511 275-UEN A Section 14
IED physical connections

If the 9-2 process values to Switchsync PWC600 originate from

two or more separate physical merging units, they should be
synchronized to the same master. Otherwise, occasional
communication interruptions may occur.

IED Intelligent electronic device

Instance When several occurrences of the same function are available
in the IED, they are referred to as instances of that function.
One instance of a function is identical to another of the same
kind but has a different number in the IED user interfaces.
The word "instance" is sometimes defined as an item of
information that is representative of a type. In the same way
an instance of a function in the IED is representative of a
type of function.
IP 1. Internet protocol. The network layer for the TCP/IP
protocol suite widely used on Ethernet networks. IP is a
connectionless, best-effort packet-switching protocol. It
provides packet routing, fragmentation and reassembly
through the data link layer.

working and encompasses both network layer and transport
layer protocols. While TCP and IP specify two protocols at
specific protocol layers, TCP/IP is often used to refer to the
entire US Department of Defense protocol suite based upon
these, including Telnet, FTP, UDP and RDP.

UTC Coordinated Universal Time. A coordinated time scale,
maintained by the Bureau International des Poids et Mesures
(BIPM), which forms the basis of a coordinated
dissemination of standard frequencies and time signals. UTC
is derived from International Atomic Time (TAI) by the
addition of a whole number of "leap seconds" to synchronize
it with Universal Time 1 (UT1), thus allowing for the
eccentricity of the Earth's orbit, the rotational axis tilt (23.5

443

degrees), but still showing the Earth's irregular rotation, on

which UT1 is based. The Coordinated Universal Time is
expressed using a 24-hour clock, and uses the Gregorian
calendar. It is used for aeroplane and ship navigation, where
it is also sometimes known by the military name, "Zulu
time." "Zulu" in the phonetic alphabet stands for "Z", which
stands for longitude zero.
