Real Power Controller, Set Point Values [GCP-21/22]
These screens appear only if the generator real power controller has been configured to "ON".
NOTE
The fixed-value power control does not take into account the mains interchange point. If excess power
is generated, it will be exported to the mains. If there isn’t enough power generated, the deficit in
power will be imported from the mains.
Engine starting depends on whether an automatic start/stop operation has been enabled or disabled. If
it has been disabled, the engine will always start.
Parameter 26
Power controller
Pset1 I0000kW
P controller: set point 1 C/I/E 0 to 6,900 kW
Set point 1 is active when Automatic 1 (voltage applied to terminal 3) is enabled.
The mains interchange (import/export) real power is then controlled to the config-
ured value.
Real generator power is controlled to the entered value.
C...................The letter C stands for fixed set point control (= constant load). The
generator will supply a constant level of power. The engine is always
started on activation of fixed set point power.
Real mains interch. (import/export) real power is controlled to the entered value.
I ....................The letter I stands for import power (power supplied by the mains).
The mains always supply the power set here as long as the minimum
and maximum generator real power are not exceeded (generator
power swings).
E ...................The letter E stands for export power (power supplied to the mains).
The power set here is always supplied to the mains as long as the
minimum and maximum generator real power are not exceeded (gen-
erator power swings).
Parameter 27
Power controller
Pset2 I0000kW
P controller: set point 2 C/I/E 0 to 6,900 kW
Set point 2 is active when Automatic 2 (voltage applied to terminal 5) is enabled
and no external set point value (0/4 to 20 mA or interface) has been enabled. The
mains interchange (import/export) real power is controlled to the configured value.
Real generator power is controlled to the entered value.
C...................The letter C stands for fixed set point control (= constant load). The
generator will supply a constant level of power. The engine is always
started on activation of fixed set point power.
Real mains interch. (import/export) real power is controlled to the entered value.
I ....................The letter I stands for import power (power supplied by the mains).
The mains always supply the power set here as long as the minimum
and maximum generator real power are not exceeded (generator
power swings).
E ...................The letter E stands for export power (power supplied to the mains).
The power set here is always supplied to the mains as long as the
minimum and maximum generator real power are not exceeded (gen-
erator power swings).
