3.2 Function description of the voltage regulation

The TAPCON® serves to keep constant the output voltage of a transformer
with an on-load tap-changer.

The TAPCON® compares the transformer's measured voltage (Vactual) with a

defined reference voltage (Vdesired). The difference between Vactual and Vdesired
is the control deviation (dV).

The TAPCON® parameters can be optimally adjusted to the line voltage re-
sponse to achieve a balanced control response with a small number of tap-
change operations.

The following diagram shows an overview of voltage regulation.

4 Packaging, transport and storage

4.1 Packaging, transport and storage

4.1.1 Suitability, structure and production

The goods are packaged in a sturdy cardboard box. This ensures that the
shipment is secure when in the intended transportation position and that
none of its parts touch the loading surface of the means of transport or touch
the ground after unloading.

The box is designed for a maximum load of 10 kg.

Inlays inside the box stabilize the goods, preventing impermissible changes
of position, and protect them from vibration.

4.1.2 Markings
The packaging bears a signature with instructions for safe transport and cor-
rect storage. The following symbols apply to the shipment of non-hazardous
goods. Adherence to these symbols is mandatory.

Table 6: Shipping pictograms

4.2 Transportation, receipt and handling of shipments

In addition to oscillation stress and shock stress, jolts must also be expected
during transportation. In order to prevent possible damage, avoid dropping,
tipping, knocking over and colliding with the product.

If a crate tips over, falls from a certain height (e.g. when slings tear) or expe-
riences an unbroken fall, damage must be expected regardless of the
weight.

Every delivered shipment must be checked for the following by the recipient
before acceptance (acknowledgment of receipt):
▪ Completeness based on the delivery slip
▪ External damage of any type.

The checks must take place after unloading when the crate or transport con-
tainer can be accessed from all sides.

30 TAPCON® 3587317/06 EN Maschinenfabrik Reinhausen 2015

4 Packaging, transport and storage

Visible damage If external transport damage is detected on receipt of the shipment, proceed
as follows:
▪ Immediately record the transport damage found in the shipping docu-
ments and have this countersigned by the carrier.
▪ In the event of severe damage, total loss or high damage costs, immedi-
ately notify the sales department at Maschinenfabrik Reinhausen and
the relevant insurance company.
▪ After identifying damage, do not modify the condition of the shipment
further and retain the packaging material until an inspection decision
has been made by the transport company or the insurance company.
▪ Record the details of the damage immediately onsite together with the
carrier involved. This is essential for any claim for damages!
▪ If possible, photograph damage to packaging and packaged goods. This
also applies to signs of corrosion on the packaged goods due to mois-
ture inside the packaging (rain, snow, condensation).
▪ Be absolutely sure to also check the sealed packaging.

Hidden damage When damages are not determined until unpacking after receipt of the ship-
ment (hidden damage), proceed as follows:
▪ Make the party responsible for the damage liable as soon as possible by
telephone and in writing, and prepare a damage report.
▪ Observe the time periods applicable to such actions in the respective
country. Inquire about these in good time.

With hidden damage, it is very hard to make the transportation company (or
other responsible party) liable. Any insurance claims for such damages can
only be successful if relevant provisions are expressly included in the insur-
ance terms and conditions.

4.3 Storage of shipments

When selecting and setting up the storage location, ensure the following:
▪ Protect stored goods against moisture (flooding, water from melting
snow and ice), dirt, pests such as rats, mice, termites and so on, and
against unauthorized access.
▪ Store the crates on timber beams and planks as a protection against ris-
ing damp and for better ventilation.
▪ Ensure sufficient carrying capacity of the ground.
▪ Keep entrance paths free.
▪ Check stored goods at regular intervals. Also take appropriate action af-
ter storms, heavy rain or snow and so on.

5.3 Connecting device

The following section describes how to establish the electrical connection to
the device.

WARNING Electric shock

Risk of fatal injury due to connection mistakes
► Ground the device with a protective conductor using the grounding
screw on the housing.
► Note the phase difference of the secondary terminals for the current
transformer and voltage transformer.
► Connect the output relays correctly to the motor-drive unit.

Supply the voltage via separators and ensure that current paths can be
short circuited. Fit the separator, clearly labeled, near the device's power
supply so that it is freely accessible. This will allow the device to be re-
placed with ease in the event of a defect.

5.3.1 Cable recommendation

Please note the following recommendation from Maschinenfabrik Reinhau-
sen when wiring the device.

Excessive line capacitance can prevent the relay contacts from breaking the
contact current. In control circuits operated with alternating current, take into
account the effect of the line capacitance of long control cables on the func-
tion of the relay contacts.

5.3.4.4 Information about shielding the CAN bus

In order for the CAN bus to operate faultlessly, you have to connect the
shielding using one of the following variants. If you are not able to use any of
the variants detailed below, we recommend using fiber optic cables. Fiber
optic cables decouple the voltage regulators and are not sensitive to electro-
magnetic interferences (surge and burst).

NOTICE Damage to the device

If you connect the CAN bus cable to devices with different potential, current
may flow over the shielding. This current may damage the device.
► Connect the devices to a potential compensation rail to compensate for
potential.
► If both devices have different potentials, only connect the CAN bus ca-
ble's shielding to one device.

Variant 1: The connected devices share the same potential

If the devices to be connected share the same potential, proceed as follows:

1. Connect all devices to a potential compensation rail to compensate for
the potential.
2. Connect CAN bus cable's shielding to all connected devices.

Variant 2: The connected devices have different potential

Note that the shielding is less effective with this variant.

40 TAPCON® 3587317/06 EN Maschinenfabrik Reinhausen 2015

5 Mounting

If the devices to be connected have different potential, proceed as follows:

► Connect CAN bus cable's shielding to just one device.

can also specify the delay time following a longer observation period. In this
regard, it is useful to register how the actual voltage progresses and the
number of tap-change operations per day.

6.3.2 Checking parallel operation

This section describes how you can run the function test for parallel opera-
tion.

Requirements To obtain perfect functioning in parallel operation, the TAPCON® must be

commissioned in simplex mode. Make sure that the conditions below have
been fulfilled.
▪ All TAPCON® units are set to the same operating parameters for "de-
sired value" [► 57] and "delay time T1" [► 63]
▪ "Activate parallel operation" [► 85] parameter set to ON
▪ Parallel operation method [► 86] selected.
▪ A different CAN bus address [► 89] (≠ 0) is set for all TAPCON®

6.3.2.1 Checking circulating reactive current sensitivity

This section describes how to run the function test for circulating reactive
current sensitivity.
ü Select the "Circulating reactive current" parallel operation method
[► 86].
ü Set circulating reactive current sensitivity to a value of 0% [► 86].
1. Adjust both transformers in simplex mode to the same actual voltage by
means of the on-load tap-changer.
2. Connect the transformers in parallel and enable the parallel control.
ð The two TAPCON® units must still be in a state of equilibrium.
ð The status display in the Parallel operation menu lights up blue.
3. On one of the two transformers, raise the tap position of the on-load tap-
changer by one setting; on the second transformer, lower the tap posi-
tion of the on-load tap-changer by one setting.
ð The two TAPCON® units must still be in a state of equilibrium.
4. Adjust the circulating reactive current sensitivity until the result displayed
in the Measured values menu item exceeds the set value for the band-
width by approx. 0.2% to 0.3%.
5. Set the value given in the previous step for all TAPCON® units in paral-
lel operation.

6. Press to select auto mode for all TAPCON® units.

ð All of the TAPCON® units return the on-load tap-changer units to
the original tap positions.
ð The function test for circulating reactive current sensitivity is complete.

If the earlier tap positions are not reached, increase the parameter value of
the circulating reactive current sensitivity.

If one of the two on-load tap-changer units switches one or more tap posi-
tions higher and the other switches the same amount lower, you need to re-
duce the parameter value of the circulating reactive current sensitivity.

After you have set the "circulating reactive current sensitivity" parameter,
continue with the function test for the circulating reactive current blocking
limit described in the next section.

ess step, wait approximately 2 to 3 seconds between the individual steps.

3. In the Parallel operation > Parallel operation method menu item, set
the circulating reactive current parallel operation method.
4. Reduce the circulating reactive current blocking limit parameter from the
set value of 20% in steps of 1% until the message Circulating reactive
current blocking limit exceeded is displayed.
ð Any further regulation is blocked.
ð After the set delay time for the parallel operation error message has
elapsed, the circulating reactive current blocking message is dis-
played
5. Increase the circulating reactive current blocking limit parameter again
until the message Circulating reactive current limit exceeded disap-
pears.

6. Press to select auto mode.

ð The motor-drive unit automatically returns to the original operating
position.
7. Set the value determined for the "circulating reactive current blocking
limit" for the TAPCON® units in parallel operation as well.

If one TAPCON® or all of the TAPCON® units indicate Circulating reactive

current blocking limit exceeded even though the control inputs are correctly
connected for all TAPCON® units, all of the TAPCON® units block.
This could be due to various causes. Further information is given in the
chapter Troubleshooting [► 154].

6.3.2.3 Checking tap synchronization method

This section describes how to run the function test for tap synchronization
(master/follower).

In parallel operation in accordance with the Automatic tap synchroniza-

tion method, the tap positions of the transformers running in parallel are
compared. It is therefore necessary that the transformers have the same
position designation and that the Raise and Lower signals produce the
same voltage change in all transformers.

NOTICE Damage resulting from formation of circulating reactive current

If the parameters are not set correctly, damage may result from the forma-
tion of circulating reactive current and the resulting overload of transmission
lines and transformers.
► Check transformer type plate.
► Set TAPCON® parameters in accordance with the configuration of the
transformers.

Before starting the function test, you must carry out the following steps:
1. Assign the master function to one TAPCON® [► 87].
2. Assign the follower function to the other TAPCON® units.
3. Compare the tap position displays of master and follower . All
of the TAPCON® units must display the same tap position. If this is not
the case, switch all TAPCON® units to the same tap position.

section. For voltage regulation, you can set the following parameters:
▪ Desired values
– Desired value 1
– Desired value 1...3 (optional)
– Desired value 1...5 (optional)
▪ Select the desired value (optional)
▪ Min./max. desired value setting (optional)
▪ Active power-dependent adjustment of desired voltage value TDSC (op-
tional)
▪ Bandwidth
▪ Delay time T1
▪ Time response T1
▪ Delay time T2
▪ Remote behavior

measurement channels)
▪ Control phase (only when using the UI 3 module and measuring with 3
measurement channels)

For voltage regulation, you can set delay time T1 and also delay time T2.
The following sections describe how the regulation function responds in both
cases:

 7 Functions and settings

Behavior only with delay time T1

If the measured voltage Uactual is within the set bandwidth , no control

commands are issued to the motor-drive unit for the tap-change operation.
Control commands will also not be issued to the motor-drive unit if the meas-
ured voltage returns to the tolerance bandwidth within the set delay time
T1 . However, if the measured voltage deviates from the set bandwidth for
a long period , a tap-change command occurs after expiration of the
set delay time T1. The on-load tap-changer carries out a tap-change in a
raise or lower direction to return to the tolerance bandwidth.

tion is initiated.

Behavior with delay times T1 and T2

Delay time T2 can be used to correct major control deviations more quickly.
Ensure that you set a lower value in the "Delay time T2" parameter than in
the "Delay time T1" parameter.

If the measured voltage Uactual deviates from the set bandwidth for a long
period , a control impulse is output to the motor-drive unit after the set de-
lay time T1 . If the measured voltage Uactual is still outside the bandwidth,
delay time T2 starts once delay time T1 is complete. Once delay time T2
is complete, a control impulse is again output to the motor-drive unit for the
tap change to return to the tolerance bandwidth.

The following sections describe how to set the relevant control parameters.

7.1.1 Desired values

You can use the "Desired value" parameter to set up to 5 desired voltage
values Udesired depending on the equipment. The device always uses one of
the set desired values for control. You can define the desired value used for
control by means of the "Select desired value" parameter.

Maschinenfabrik Reinhausen 2015 3587317/06 EN TAPCON® 57

 7 Functions and settings

Setting options The device provides the following ways of changing the desired voltage val-
ue during operation:
▪ Using the operating screen in the control parameters menu item or the
web-based visualization
▪ Desired value selection using binary inputs (optional)
▪ Using an analog interface (0…20 mA, 4…20 mA or 0…10 V) depending
on the equipment (optional)

Reference parameter Desired values set in kV refer to the primary voltage of the voltage trans-
former. Desired values set in V refer to the secondary voltage of the voltage
transformer. You can toggle between primary values and secondary values
in the "Desired value" parameter.

Setting the desired value

To set the desired value, proceed as follows:

1. Go to Settings > Parameter > Control > Desired value.
2. Enter desired value.
3. Press the Accept button to save the modified parameter.

Selecting the desired value (optional)

You can use this parameter to select the desired value used for control.

To specify the desired value using an analog signal, you need to create a
signal at the Desired value setting release input. If this is not done, the de-
vice uses the set desired value 1.

To select the desired value, proceed as follows:

1. Go to Settings > Parameter > Control > Select desired value.
2. Select the desired value you want in the list.
3. Press the Accept button to save the modified parameter.

7.1.2 Active power-dependent adjustment of desired voltage value

(optional)
The TAPCON® Dynamic Setpoint Control (TDSC) function is used to adapt
the desired voltage value depending on the measured active power. This al-
lows you to compensate for a voltage drop during increased load or an in-
crease in voltage due to a decentralized feed-in.

Depending on whether positive or negative active power is measured, the

desired value calculation is based on 2 linear equations (see example in dia-
gram below).

Response to value falling below active power Pmin

If the measured active power Pmeas falls below the set parameter Pmin, the val-
ue Umin is adopted as the desired value.

Response to a measured active power Pmeas = 0 MW:

If the measured active power Pmeas = 0, the set parameter U0 is adopted.

Linear dependency with negative active power:

If the measured active power Pmin ≤ Pmeas ≤ 0, the desired value is calculated
using the following formula:

Linear dependency with positive active power:

If the measured active power 0 ≤ Pmeas ≤ Pmax, the desired value is calculated
using the following formula:

To activate the active power-dependent adjustment of the desired voltage

value, you need to set the following parameters:

7 Functions and settings

Activate TDSC

The TDSC function is only active when the device can calculate the active
power (correct current measurement and voltage measurement) and the re-
quired parameters are set. If this isn't done, the voltage is regulated to the
set desired value [► 57]. You can activate or deactivate the power-depend-
ent adjustment of the desired voltage value as follows:
▪ Parameter
▪ Digital inputs TDSC on and TDSC off (optional)
▪ Control system command (optional)

If you activate TDSC, the line drop compensation (R&X compensation or Z

compensation) function is deactivated.

To activate/deactivate TDSC using parameters, proceed as follows:

1. Go to Settings > Parameters > Control > Activate TDSC.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.

TDSC Umax/Umin

You can use these parameters to set the maximum and minimum desired
value. The maximum or minimum desired value is activated when the meas-
ured active power reaches the set minimum or maximum active power.
1. Go to Settings > Parameters > Control > TDSC Umax/Umin.
2. Enter maximum/minimum desired value.
3. Press the Accept button to save the modified parameter.

7.1.3 Bandwidth
You can use this parameter to set the maximum permissible deviation in
measured voltage Uactual from the desired value Udesired. The following section
describes how you determine and set the bandwidth.

Determining bandwidth

In order to set the correct value, the transformer's step voltage and nominal
voltage must be known. Note that a large bandwidth will result in a large
control deviation.

The bandwidth must always be greater than the following value:

Figure 36: Calculation of minimum bandwidth

Un-1 Step voltage of tap position n-1

Un Step voltage of tap position n
Unom Nominal voltage

The following transformer values are used to determine the minimum band-
width:
Nominal voltage Unom = 11,000 V
Step voltage in tap position 4 UStep4 = 11,275 V
Step voltage in tap position 5 UStep5 = 11,000 V

Setting the bandwidth

To set the bandwidth, proceed as follows:

1. Go to Settings > Parameter > Control > Bandwidth.
2. Enter bandwidth.
3. Press the Accept button to save the modified parameter.

7.1.4 Delay time T1

Delay time T1 delays the issuing of a tap-change command for a defined pe-
riod. This prevents unnecessary tap-change operations if the tolerance
bandwidth is exited briefly.

Setting delay time T1

To set the delay time T1, proceed as follows:

1. Go to Settings > Parameter > Control > Delay time T1.
2. Enter delay time T1.
3. Press the Accept button to save the modified parameter.

Selecting time response T1

You can use this parameter to set the time response for delay time T1. You
can select the following options:
▪ Linear time response
▪ Integral time response

Linear time response With linear time response, the device responds with a constant delay time
regardless of the control deviation.

Integral time response With integral time response, the device responds with a variable delay time
depending on the control deviation. The greater the control deviation (ΔU) in
relation to the set bandwidth (B), the shorter the delay time. This means that
the device responds faster to large voltage changes in the grid. Regulation
accuracy improves as a result but the frequency of tap-changes increases
too.

1. Go to Settings > Parameter > Control > Time response T1.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.

7.1.5 Delay time T2

You can use this parameter to set the delay time T2. Delay time T2 is used
to compensate for large control deviations faster.

The delay time T2 only takes effect if more than one tap-change operation is
required to correct the control deviation. The first output pulse occurs after
the set delay time T1. After the set tap-change delay time T2 has elapsed,
additional pulses occur in order to correct the existing control deviation.

The following requirements must be noted to set delay time T2:

▪ The delay time T2 must be greater than the switching pulse time.
▪ The delay time T2 must be greater than the maximum operating time of
the motor-drive unit.
▪ The delay time T2 must be less than the value set for delay time T1.

Setting delay time T2

To set the delay time T2 proceed as follows:

1. Go to Settings > Parameter > Control > Delay time T2.
2. Set delay time T2.

3. Press the Accept button to save the modified parameter.

7.1.7 Regulation mode

If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module, you can use this parameter to set whether you want 1-phase
voltage regulation or voltage regulation to the average value of the 3 phases.
You can select the following options:
▪ Single-phase: Voltage is automatically regulated to one selected phase.
Limit value monitoring, line drop compensation, and parallel operation
also take place on the selected phase using the circulating reactive cur-
rent minimization method.
▪ Average value regulation: Voltage is automatically regulated to the aver-
age of the 3 phases. Limit value monitoring, line drop compensation,
and parallel operation also take place using the circulating reactive cur-
rent minimization method to the average of the 3 phases.

If you activate the average value regulation option, automatic voltage regu-
lation is blocked should the voltage or current measurement of one of the 3
phases fail.

7.3.1 Setting the switching pulse for controlling the motor-drive unit
You can use the switching pulse type, switching pulse time and switching
pulse pause parameters to adapt the switching pulse of the TAPCON® to
the requirements of the motor-drive unit's control.

Selecting switching pulse type

You can use this parameter to toggle the switching pulse between a continu-
ous pulse or time-controlled switching pulse.

Maschinenfabrik Reinhausen 2015 3587317/06 EN TAPCON® 75

 7 Functions and settings

Continuous pulse Selecting the "Continuous pulse" option causes the TAPCON® to issue the
switching pulse in AVR Auto operating mode until the measured value is
back within the bandwidth. In AVR Manual operating mode, the device is-
sues the switching pulse for as long as you press the or key.

If the TAPCON® is operated as a follower in parallel operation in this case,

then the TAPCON® issues the switching pulse until one of the following re-
quirements has been met:
▪ The set motor runtime has been reached
▪ The Motor running signal switches states from 1 to 0
▪ The tap position required by the master has been reached

A pause is enforced after every switching pulse before another switching

pulse is issued.

Time-controlled switching Selecting the "Time-controlled switching pulse" option causes the
pulse TAPCON® to issue the switching pulse for a set duration. A pause is en-
forced after every switching pulse before another switching pulse is is-
sued.

If you use a motor-drive unit from Maschinenfabrik Reinhausen GmbH, you

need to select the "Time-controlled switching pulse" option.

7.3.2 Setting motor runtime monitoring

The motor-drive unit's runtime can be monitored by the device. This function
is used to identify motor-drive unit malfunctions during the tap-change oper-
ation and to trigger any actions needed.

Behavior The motor-drive unit issues the Motor-drive unit running signal during the
tap-change operation. This signal is present until the tap-change operation is
complete. The device compares the duration of this signal with the set motor
runtime. If the set motor runtime is exceeded, the device triggers the follow-
ing actions:
1. Motor runtime exceeded event.
2. Pulse signal via Trigger motor protective switch output relay

Note that motor-drive units with cycle settings or motor-drive units without
stepped switching behavior will run for longer under certain circumstances.
Set a longer motor runtime for such units.

The following parameters are available to configure the motor runtime moni-
toring:

7.4 Line drop compensation

You can use the compensation function to compensate for the load-depend-
ent voltage drop between the transformer and consumer. The device pro-
vides 2 methods of compensation for this purpose:
▪ R&X compensation
▪ Z compensation

7.4.1 R&X compensation

R&X compensation can compensate for voltage losses on the lines and
therefore ensure correct voltage on the consumer. This requires precise line
data. After you have entered all of the line data, the TAPCON® automatically
calculates the ohmic and inductive voltage drop and takes this into account
for automatic voltage regulation.

7.4.2 Z compensation
To keep the voltage constant for the consumer, you can use Z compensation
to activate a current-dependent increase in voltage. You can also define a
limit value to avoid excess voltage on the transformer.

Figure 44: Z compensation

To use Z compensation, you need to calculate the increase in voltage (ΔU)

taking the current into account. Use the following formula for this purpose:

motor-drive unit to the device. In accordance with your order, the tap position
is transmitted in one of the following ways:
▪ Digital signal
– BCD
– N/O contact series
▪ Analog signal
– Injected current (0/4…20 mA)
– Voltage (0…10 V)

7.6 Parallel operation

In theParallel operation menu item, you can set the parameters needed for
parallel transformer operation. Parallel transformer operation is used to in-
crease the throughput capacity or short-circuit capacity in one place.

84 TAPCON® 3587317/06 EN Maschinenfabrik Reinhausen 2015

7 Functions and settings

Conditions for parallel Compliance with the following general conditions is required for operating
operation transformers in parallel:
▪ Identical rated voltages
▪ Transformer power ratio (< 3 : 1)
▪ Maximum deviation of short-circuit voltages (UK) for transformers con-
nected in parallel < 10%
▪ Same number of switching groups
▪ The same current-transformer connection has to be used for all devices
running in parallel

You can control up to 16 transformers connected in parallel in one or 2

groups without detecting the system topology. Information is swapped be-
tween the voltage regulators operating in parallel using the CAN bus. Paral-
lel operation is activated using one of 2 status inputs or the control system.

Parallel operation method The device supports parallel operation following the methods described be-
low:
▪ Parallel operation following the "Circulating reactive current minimiza-
tion" principle
▪ Parallel operation following the "Tap synchronization" (master/follower)
principle

You must select the same parallel operation method (circulating reactive
current minimization or tap synchronization) for all voltage regulators oper-
ating in parallel. Otherwise you cannot operate the devices in parallel.

Figure 46: Setting parallel operation

The following sections describe how you can set the parameters.

7.6.1 Activating parallel operation

You can use this parameter to activate or deactivate parallel operation.

Maschinenfabrik Reinhausen 2015 3587317/06 EN TAPCON® 85

3. Press the Accept button to save the modified parameter.

7.6.2 Selecting parallel operation method

You can use this parameter to select a parallel operation method. The fol-
lowing methods can be assigned to the device.
▪ Circulating reactive current minimization
▪ Tap synchronization (master/follower/auto)

You must select the same parallel operation method (circulating reactive
current minimization or tap synchronization) for all voltage regulators oper-
ating in parallel. Otherwise you cannot operate the devices in parallel.

The following sections describe how you can set the parameters for a paral-
lel operation method.

7.6.2.1 Circulating reactive current minimization

When the circulating reactive current parallel operation method is select-

ed, then parallel operation is carried out using the circulating reactive current
minimization method. The circulating reactive current is calculated from the
transformer currents and their phase angles. A voltage proportional to the
circulating reactive current is added to the independently regulating
TAPCON® as a correction for the measurement voltage. You can use the
circulating reactive current sensitivity parameter to reduce or increase this
voltage correction.

The circulating reactive current method is suited to transformers connected

in parallel with a similar nominal output and short-circuit voltage UK and to
vector groups with the same and different step voltages. This does not re-
quire any information about the tap position.

To select the circulating reactive current minimization parallel operation

method, proceed as follows:
1. Go to Settings > Parameters > Parallel operation > Parallel opera-
tion method.
2. Select the Circulating reactive current option.
3. Press the Accept button to save the modified parameter.

To configure the circulating reactive current minimization parallel operation

method, you have to also set the following parameters:
▪ Circulating reactive current sensitivity
▪ Circulating reactive current blocking limit

86 TAPCON® 3587317/06 EN Maschinenfabrik Reinhausen 2015

7 Functions and settings

Setting circulating reactive current sensitivity

You can use this parameter to set the influence of circulating reactive current
on how the control deviation is calculated. The larger the set value, the
greater the calculated control deviation as a result of circulating reactive cur-
rent.

To set the circulating reactive current sensitivity, proceed as follows:

1. Go to Settings > Parameters > Parallel operation >Circulating reac-
tive current sensitivity.
2. Enter the circulating reactive current sensitivity.
3. Press the Accept button to save the modified parameter.

Setting the circulating reactive current blocking limit

You can use this parameter to set the limit value for the maximum permissi-
ble circulating reactive current. This value relates to the rated current of the
current transformer. If, during parallel operation, the circulating reactive cur-
rent exceeds the set limit value, the device triggers the Circulating reactive
current blocking limit exceeded event. All devices operating in the parallel
operation group are blocked.

To set the circulating reactive current blocking limit, proceed as follows:

1. Go to Settings > Parameters > Parallel operation > Circulating reac-
tive current blocking limit.
2. Enter the circulating reactive current blocking limit.
3. Press the Accept button to save the modified parameter.

7.6.2.2 Setting tap synchronization

With the Tap synchronization parallel operation method, you need to desig-
nate one voltage regulator as the master and all others as followers. The
master handles voltage regulation and transmits its latest tap positions to all
followers via the CAN bus. The followers compare the tap position received
with their own tap position. If the tap position is not the same, the followers
switch to the tap position received from the master. This ensures that the
transformers operating in parallel are always in the same tap position.

If there is a tap difference between the master and follower, the master re-
frains from issuing any control commands to the motor-drive unit until all of
the followers have reached the same tap position. If the tap difference per-
sists for longer than the set delay time for parallel operation error messages,
the master triggers the Tap difference to follower event.

For the tap synchronization method, you can select the following options:
Option Description
Master The voltage regulator is designated as the master.
Follower The voltage regulator is designated as the follower.

chronization If no master is detected, the voltage regulator with the

lows:
1. Go to Settings > Parameters > Parallel operation > Parallel opera-
tion method.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.

To configure the tap synchronization parallel operation method, you also

have to set the following parameters:
▪ Master/follower current blocking
▪ Maximum tap difference

Master/follower current blocking

You can use this parameter to activate the circulating reactive current block-
ing limit for the tap synchronization parallel operation method. The
TAPCON® thereby calculates and monitors the circulating reactive current in
the same manner as for the circulating reactive current minimization parallel
operation method. The Circulating reactive current blocking [► 86] parame-
ter is used to set the limit value.

To activate circulating reactive current blocking for the tap synchronization

parallel operation method, proceed as follows:
1. So to Settings > Parameters > Parallel operation > Master/follower
current blocking.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.

Maximum tap difference

You can use this parameter to set the maximum permissible tap difference
between followers and master on the follower.

If the tap difference is greater than the set maximum tap difference to the
master, the follower immediately blocks regulation. After the set delay time
for parallel operation error messages has elapsed, the follower issues the
Permitted tap difference to master exceeded message.

To set the maximum permissible tap difference, proceed as follows:

1. Go to Settings > Parameters > Parallel operation > Maximum tap
difference.

3. Press the Accept button to save the modified parameter.

7.6.3 Assigning a CAN bus address

You can use this parameter to assign a CAN bus address to the device. So
that all devices can communicate using the CAN bus, each device requires a
unique identifier. Addresses can be set from 1 to 16. If the value is set to 0,
then no communication takes place.

You have to assign an individual CAN bus address to each voltage regula-
tor when activating parallel operation. Up to 16 CAN participants are sup-
ported.

1. Go to Settings > Parameters > Parallel operation > CAN bus ad-
dress.
2. Enter CAN bus address.
3. Press the Accept button to save the modified parameter.

lation normal automatic voltage regulation
Auto blocking Automatic voltage regulation is blocked.
cosφ interpolation Continuation of parallel operation with interpolated
values (only possible with circulating reactive cur-
rent parallel operation method)

ror message so that brief fault messages are not received if the motor-drive
units involved in the parallel operation have different runtimes. Once the set

delay time has elapsed, the event is issued at the output relay. Depending
on the type of parallel operation error, automatic regulation can be blocked
and the on-load tap-changers can only be adjusted in manual mode.

To set the delay time for the parallel operation error message, proceed as
follows:
1. Go to Settings > Parameters > Parallel operation > Delay time for
the parallel operation error message.
2. Enter the delay time.
3. Press the Accept button to save the modified parameter.

er is fitted with an auxiliary contact so that its status can be reported for this
purpose.

Figure 48: Example of a circuit breaker configuration

The TAPCON® uses the assignment to detect which transformers are con-
nected in parallel with one another.

Upon delivery, the device is configured in accordance with your order. Note
the connection diagram provided for the configuration.

Note the following conventions for the circuit breaker configuration:

▪ Nodes 1...16 correspond to the secondary side of transformers 1...16
(node 1 = transformer 1, node 2 = transformer 2 ...).
▪ You can use nodes 17...48 to configure the connection of the circuit
breakers on the secondary side.
▪ Nodes 49...64 correspond to the primary side of transformers 1...16
(node 49 = transformer 1, node 50 = transformer 2 ...)
▪ You can use nodes 65...80 to configure the connection of the circuit
breakers on the primary side.

If you assign the node A = 0 and node B = 0 node pair to a circuit breaker,
the circuit breaker is deactivated for topology recording.

You have to assign a node pair to every circuit breaker. To do so, proceed
as follows:

7.7 Limit values

For various measured values, you can define limit values which are moni-
tored by the device. Depending on the measured value, you can define dif-
ferent numbers of limit values. The following measured values can be moni-
tored:
2nd lower 1st lower 1st upper 2nd up-
limit limit limit per limit
Voltage U<< U< U> U>>

The "lower" limit values are monitored for whether the measured value
reaches or falls below the limit value. The "upper" limit values are monitored
for whether the measured value reaches or exceeds the limit value.

If you are measuring voltage and current in 3 phases, you can also monitor
the following limit values:
▪ Difference in voltage between the 3 phases: ∆U 3ph
▪ Phase symmetry between the 3 phases: ∆φ 3ph

Various parameters for configuring limit value monitoring are provided for
each limit value.

The parameters available and ways in which they can be selected may vary

Relative/absolute limit value

You can use this parameter to set whether the device is to use the "Absolute
limit value" or "Relative limit value".

Absolute limit value

You can use this parameter to set the limit value as a fixed absolute value.
Unlike the relative value, this limit is not dependent on a reference value.

Maschinenfabrik Reinhausen 2015 3587317/06 EN TAPCON® 95

 7 Functions and settings

Relative limit value

You can use this parameter to set the limit value relative to a reference val-
ue.

Hysteresis limit value

You can use this parameter to set the hysteresis. For "Upper limit value", the
hysteresis is deducted from the limit value and for "Lower limit value", it is
added to the limit value. When a limit value is infringed, the set device be-
havior is only reset once the measured value has exceeded the hysteresis.
The purpose of the hysteresis is to allow the device to ignore small fluctua-
tions around the limit value.

Delay time limit value

With this parameter, you can set the delay time. If a limit value is infringed,
the device only undertakes the set behavior once the delay time has
elapsed. The purpose of the delay time is to allow the device to ignore brief
limit value infringements.

Behavior limit value

You can use this parameter to define how the device behaves when a limit
value is infringed. The options available may vary depending on the limit val-
ue. The following options are available:

 1 Introduction

1 Introduction
The document describes how parallel operation is detected via topology.
Note the operating instructions provided.

2 Detecting parallel operation via topology (optional)

2 Detecting parallel operation via topology (optional)

The topology function is used to detect which transformers are in parallel op-
eration on the basis of the position of the circuit breakers. Each circuit break-
er is fitted with an auxiliary contact so that its status can be reported for this
purpose.

Figure 1: Example of a circuit breaker configuration

A TAPCON® records the status of the circuit breakers via digital inputs and
reports this to the connected TAPCON® by CAN bus. On the basis of the
status, the TAPCON® decide whether parallel operation is active or not.

Maschinenfabrik Reinhausen 2014 4113767/00 EN TAPCON® 5

 2 Detecting parallel operation via topology (optional)

Topology master Topology client Topology client Topology client

Figure 3: Operating principle

The TAPCON® are split into two groups for data transmission by CAN bus:
▪ Topology master: TAPCON® which records the status of the circuit
breakers via digital inputs and reports this by CAN bus.
▪ Topology client: TAPCON® which receives the status of the circuit
breakers by CAN bus.

2.1 Setting topology master

To configure the topology master, you need to undertake the following set-
tings:
▪ Prim/sec. topology
▪ Name of transformers 1(2)...16
▪ CAN bus address
▪ Circuit breaker configuration

Prim/sec. topology

You can use this parameter to set the condition for when the transformers
are considered to be connected in parallel. You can select the following op-
tions:
▪ Secondary side: Transformators are considered to be connected in par-
allel when the circuit breakers on the secondary side of the transformer
are closed.
▪ Both sides: Transformers are considered to be connected in parallel
when the circuit breakers on the primary and secondary sides of the cir-
cuit breaker are closed.

6 TAPCON® 4113767/00 EN Maschinenfabrik Reinhausen 2014

2 Detecting parallel operation via topology (optional)

▪ At least one side: Transformers are considered to be connected in par-

allel when the circuit breakers on the primary or secondary side of the
transformer are closed.

To set the condition, proceed as follows:

1. Go to Settings > Parameters > Parallel operation > Prim/sec topolo-
gy.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.

Name of transformers 1(2)...16

You can use these parameters to set the name of the transformers. The de-
vice uses the name in the information display for the topology.

To set the transformer name, proceed as follows:

1. Go to Settings > Parameters > Parallel operation > Name of trans-
formers 1(2)...16.
2. Enter the desired name.
3. Press the Accept button to save the modified parameter.

CAN bus address

Set the CAN bus address of the topology master to 1. Observe the informa-
tion provided in the Assigning CAN bus address section.

Circuit breaker configuration

You can set the assignment of circuit breakers to the individual node points.
The TAPCON® uses the assignment to detect which transformers are con-
nected in parallel with one another.

Upon delivery, the device is configured in accordance with your order. Note
the connection diagram provided for the configuration.

Note the following conventions for the circuit breaker configuration:

▪ Nodes 1...16 correspond to the secondary side of transformers 1...16
(node 1 = transformer 1, node 2 = transformer 2 ...).
▪ You can use nodes 17...48 to configure the connection of the circuit
breakers on the secondary side.
▪ Nodes 49...64 correspond to the primary side of transformers 1...16
(node 49 = transformer 1, node 50 = transformer 2 ...)
▪ You can use nodes 65...80 to configure the connection of the circuit
breakers on the primary side.

If you assign the node A = 0 and node B = 0 node pair to a circuit breaker,
the circuit breaker is deactivated for topology recording.

Maschinenfabrik Reinhausen 2014 4113767/00 EN TAPCON® 7

 2 Detecting parallel operation via topology (optional)

You have to assign a node pair to every circuit breaker. To do so, proceed
as follows:
1. Go to Settings > Topology.

Figure 4: Configuring topology

2. Select the circuit breaker you want.

Figure 5: Configuring topology for circuit breaker 1

3. Enter the desired node numbers in the node A and node B fields.
4. Press the Accept button to save the modified parameter.

2.2 Setting topology client

To use the device as topology client, you need to set the CAN bus address.
