Woodward GCP-30 Series Configuration

Manual 37278B GCP-30 Series - Genset Control
Page 74/174 © Woodward
Overview GCP-31
STOP TEST MANUAL AUTOMATIC
EXTERNAL: Breaker logic "External"
The GCB is never synchronized in this operation mode. Decoupling from the mains when in a mains parallel operation is car-
ried out via the GCB in the event of mains faults. The breaker will not automatically close in emergency power operations.
The GCB is
opened.
The GCB is not operated.
Exception:
The breaker is opened
for decoupling from the mains.
The GCB can be manually
opened and closed without syn-
chronization. The breaker is
opened for decoupling from the
mains.
The GCB is opened for stopping
or for decoupling from the mains,
but is not closed in the event of
an add-on request.
Start/Stop Ramp, Open GCB With F2 Alarm
Parameter 127
Add-on/off ramp
max.time 000s
Start/stop ramp 0 to 999 s
This time can be used to influence two functions:
Stop: The maximum amount of time generator will shed load is set here. If the gene-
rator load does not drop below 3 % of the generator rated power (Parameter 32)
with
in this time, the GCB is opened.
Start with soft loading: If the mains interchange (import/export) real power value
does not reach 0 kW in breaker logic "INTERCHANGE" within the time configured
here; a class F1 alarm and an alarm message are issued. At the same time, the relay
manager relay, which is programmed with relay manager function 78 (Appendix B)
is enabled and the MCB is prevented from opening.
Parameter 128
Open GCB with F2
max.time 000s
Max. perm. time with F2 alarms for starting a further engine 0 to 999 s
Prerequisite: Load sharing (Parameter 103) and automatic start/stop (Parameter 108
or Parameter 109) are configured to "ON". The generat
or is in isolated operation and
at least one additional generator is connected to a busbar.
If a class F2 alarm occurs the engine shutdown may be delayed by the time confi-
gured here. This permits another engine to attempt to start in order to assume the
load. After the configured time expires the engine with the F2 alarm condition will
shutdown regardless if another engine was able to start and assume the load.
PARALLEL: Breaker logic "Mains parallel"
This operation mode may be used both in the case of an isolated system, an isolated parallel system, and a system that is op-
erated in mains parallel.
The GCB is
opened.
The GCB is not operated.
Exception:
Load test by actuating
the "GCB ON" push-button.
Termination of the load test with
the "GCB OFF" push-button.
Emergency power:
The GCB is
opened for decoupling from the
mains.
Mains parallel operation can be
performed via the "GCB ON"
push-button.
The GCB is synchronized via an
add-on request and mains parallel
operation is performed. When a
shed-off request is issued, the ge-
nerator sheds load, the GCB is
opened, and the engine is shut
down following the configured
cool down period.
