Woodward GCP-30 Series Configuration

Manual 37278B GCP-30 Series - Genset Control
Page 54/174 © Woodward
Single generator in mains parallel operation
The load-dependent start/stop function is activated when all of the following conditions have been met:
• the operation mode AUTOMATIC has been selected
• interchange power control (import/export power) has been activated by one of the two discrete inputs ("Au-
tomatic 1" or "Automatic 2") (" I " or " E " power)
• one or both parameters "Load-dependent start/stop on terminal 3/5" (Parameter 108 or Parameter 109) has
been confi
gured to "ON".
Parameter 110
Minimum load
generator 0000kW
Load dependent start/stop: generator minimum set point power 0 to 6,900 kW
For the mains interchange (import/export) real power control to function, a genera-
tor power set point value is required. In many cases, starting of the engine should
only performed once a specific generator power set point value has been reached in
order to operate the generator with a reasonable degree of efficiency. For example:
At least 40 kW of real power has to be supplied by 80 kW generator before the en-
gine is to be started.
Parameter 111
Add-on delay
mains oper. 000s
Load dependent start/stop: start delay 0 to 999 s
Starting may be delayed even if the generator start power limit has been reached. In
order to avoid starting the engine in the event of short-term load swings, a start de-
lay may be entered here in seconds. The start power (Parameter 110) must 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 112
Shed-off delay
mains oper. 000s
Load dependent start/stop: stop delay 0 to 999 s
Stopping can be delayed even if the generator stop power limit 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 here in seconds. The stop power (Parameter 113) must
t
herefore be present without interruption during this period of time, in order to en-
sure that the engine is stopped. If the load rises above the set stop power limit be-
fore the time configured here expires, the counter is reset to 0.
Stopping hysteresis
NOTE
The following Parameter 113 is used to determine stopping hysteresis for single gensets in mains pa-
rallel operation, for generators connected to other generators in mains parallel operation, and in iso-
lated operation in parallel with other gensets. However, the parameter appears only once in this text.
Parameter 113
Hysteresis add-.
on/off op.0000kW
Load dependent start/stop: hysteresis 0 to 9,999 kW
The stop power value of the generator is determined via a hysteresis. The hysteresis
is used to prevent the engine continuously starting and shutting down again.
