Real Power Controller
Parameter 74
Power controller
ON
Power controller: enable ON/OFF
ON ................ Real power control is enabled. The generator will automatically load
with real power to the level configured in Pset1 (Parameter 35) or
Pset2 (Parameter 36) when the corresponding inputs (terminal 3 or 5)
are energized and the system
is in parallel with the mains. The subse-
quent screens of this function are displayed.
OFF .............. Real power control is not performed, and the subsequent screens of
this function are not displayed.
Parameter 75
power controller
ramp 000.0%/s
Power controller: set point ramp %/s 0.1 to 100.0 %/s
The GCP-30 controller has the ability to softly load and unload when paralleled.
The load reference point is changed by the control at the rate of a configured per-
cent per second. This percentage refers to the generator rated power (Para-
m
eter 21). A smaller configured percentage for the ramp rate will result in a slower
ramp rate. Conversely a larger configured percentage will result in a faster ramp
rate.
Power Limitation
Parameter 76
Power limit
P max. 000%
Power controller: maximum power limitation 10 to 120 %
If the maximum generator real load is to be limited, a percentage based on the ge-
nerator rated power (Parameter 21) is entered here. The GCP-30 will not permit the
load to exceed the configured power lim
itation value. This parameter is only func-
tional when the generator is in a mains parallel operation.
Parameter 77
Power limit
P min. 00%
Power controller: minimum power limitation 0 to 50 %
If the generator minimum real load is to be limited, a percentage based on the gene-
rator rated power (Parameter 21) is entered here. The GCP-30 will not permit the
l
oad to drop below the configured power limitation value. This parameter is only
functional when the generator is in a mains parallel operation.
