[Default]
2 [PF(P)] A power factor setpoint is determined according to the characteristic curve:
Generator power factor over generator active power.
Q(V) A power factor setpoint is calculated according to the characteristic curve:
Mains reactive power over mains voltage.
2 0.0 to 99999.9 The value entered into "Point 1 power" defines the cos phi (P) characteristic.
kW
[0.0 kW]
2 -0.999 to 1.000 The desired "Point 1 cos phi" may be configured here which defines the cos
phi (P) characteristic.
[-0.950]
The designations "+" and "-" stand for inductive/lagging (generator overex‐
cited) and capacitive/leading (generator underexcited) reactive power.
2 0.0 to 99999.9 The value entered into "Point 2 power" defines the cos phi (P) characteristic.

2 -0.999 to 1.000 The desired "Point 2 cos phi" may be configured here which defines the cos
phi (P) characteristic.

The designations "+" and "-" stand for inductive/lagging (generator overex‐
cited) and capacitive/leading (generator underexcited) reactive power.

001 to 999 s The response with a new reactive power setpoint acting on the analog com‐
mand variable 05.29 PF characteristic can be delayed.
[45 s]
Notes
The delay is realized with a PT-1 filter. Therefore the reaction times are opti‐
mized for the range 10 s until 60 s within a symmetrical characteristic curve.
The easYgen performs proportional load and/or var sharing. This
means each generator will share the load at the same percentage
level of the generator rated power when paralleled against the
mains, in an isolated operation with multiple generators paralleled,
or when re-synchronizing the common bus to the mains.
Proportional load/var sharing will not be performed when the
easYgen has the GCB closed and is in the constant power/base
load mode. A system can consist out of 16 gensets which are con‐
trolled by a single easYgen.
