Woodward GCP-30 Series Configuration

Manual 37278B GCP-30 Series - Genset Control

Isolated operation in parallel with other generators
The load-dependent start/stop function is activated for every control when the following criteria has been met:
• the operation mode AUTOMATIC has been selected
• all parameters, such as start power (Parameter 110), stop power (Parameter 113), start delay (Parameter 111),
st
op delay (Parameter 112) and the frequency set point values (Parameter 10) are identical for all controls in-
vol
ved
• one or both parameters "Load-dependent stop/start on terminal 3/5" (Parameter 108 or Parameter 109)
has/
have been configured to "ON"
• the parameters "Load sharing" (Parameter 103) or "var sharing" (Parameter 105) have been configured as
"ON"
• All generators are configured to the same rated power (Parameter 32)
NOTE
The reserve power (Parameter 116) should be selected in such a manner that expected load swings will
not overload the generator.
Parameter 116
Reserve power
isol.op. 0000kW
Load dependent start/stop: reserve power (isolated operation) 0 to 9,999 kW
Starting of an additional engine is determined via the reserve power. The reserve
power results from the currently available total generator rated real power (genera-
tor rated real power × number of closed GCB's) and the currently available total
generator actual real power. If the currently available total generator actual real
power is subtracted from the currently available total generator rated real power,
this results in the system's reserve power. If negative deviation from this reserve
power occurs, the next engine is started.

Parameter 117
Add-on delay
isol.op. 000s
Load dependent start/stop: start delay (isolated operation) 0 to 999 s
Starting may be delayed even if the engine's start power (Parameter 110) has been
reached. In order to avoid starting the engine in the event of short-term load
swings, a start delay may be entered in seconds. The start power (Parameter 110)
m
ust therefore be present without interruption during this period of time, in order
to ensure that the engine is started. If the load drops below the set start power limit
before the time configured here expires, the counter is reset to 0.
Parameter 118
Shed-off delay
isol.op. 000s
Load dependent start/stop: stop delay (isolated operation) 0 to 999 s
Stopping can be delayed even if the engine's stop power (Parameter 113) has been
reached. In order to avoid shutting the engine down in the event of short-term load
swings, a stop delay may be entered in seconds. The stop power (Parameter 113)
m
ust therefore be present without interruption during this period of time, in order
to ensure that the engine is stopped. If the load rises above the set stop power limit
before the time configured here expires, the counter is reset to 0.
