C2171.17 PCMS FUNCTIONAL DESCRIPTION

In addition to monitoring load centres and specific pieces of equipment, the PCMS will
also control limited load shedding and generator operation under certain conditions.

.1 Normal Operation

Generally the building will operate on on PLN supply. The PCMS will monitor the status of
various devices and record various parameters.

.2 Generator failure

In the event that one of the generators fails, the PCMS will compare the available
generator capacity to the connected load and send appropriate load shedding signals to
mechanical plant via the MCS. In the event the other sets trip due to overload, the
operator will manually restart and synchronise the gensets.

.3 Auto Mains Failure

During normal operation the PCMS will give a maintained signal to GCS and MCS. In the
event of failure of PLN supply the PCMS will remove these signals. The GCS will either
start generators which are not running or start all generators. The PCMS will shed non-
essential load. The incoming circuit breakers within the LVMSB on PLN supply will drop
out automatically. The load shed contactors within a distribution board on PLN supply will
drop out automatically. The PCMS will open motorised MCCBs and load shed contactors
in the system operating on genset supply.

PCMS will signal the MCS that mains has failed. PCMS will wait till load shedding is
complete (including that by MCS).

As soon as the first or next genset (if some gensets are already running) is available, the
PCMS will connect the part of the network on PLN supply to genset supply by
closing/opening appropriate 20kV breakers. Then the PCMS will restore the supply to
LVMSBs in a sequential manner as the gensets come on line (i.e. synchronise). The

EL-SPEC PT Hantaran Prima Mandiri 30 Nov’ 2018

Loggia Apartment Project – Jakarta
C2171 – POWER CONTROL AND MONITORING SYSTEM Page 87

contactor shall prepare a detailed load shedding and essential load sequence and submit
for review to Engineer.

After the genset supply is restored to the LVMSBs the PCMS will signal the MCS that
genset supply is available. At each step the PCMS will monitor the load vs available
genset capacity and proceed to the next step only if sufficient capacity is available.

On return of PLN supply the generators will automatically synchronise with the PLN
supply. After a time delay PCMS will restore the network to pre-PLN supply failure status
by opening and closing appropriate 20kV breakers. PCMS will finally restore the non-
essential load and signal MCS that PLN supply has returned.
