Description
"Generator rated voltage" is
transmitted if the result of AM
Volt. SP PID-source [%]" is 50 %.
E.g. if 105.0 % is configured here
and the result of "AM Volt. SP PID-
source [%]" is 0 - 100, the
transmitted voltage setpoint is
scaled to 95 to 105 % of
"Generator rated voltage".
The value of the transmittted
voltage setpoint is indicated by
the analog variables "14.54 Volt.
SP SPN 3386 [V]" and "14.04 Volt.
SP SPN 3386 [%]".

source [%] 2 Determined by AnalogManager
81.35
[A1 = 11.02 Voltage bias [%]]
The voltage setpoint source for
AVR via CAN J1939 may be
selected from the available data
sources.
Usually the output of the voltage
PID (0-100 %) "11.02 Voltage bias
[%]" or "14.01 Excitation AVR [%]"
is to assigned here.
4.4.4.2 Power Factor Control
The easYgen cover a wide range of power factor control tasks:
• Controller type can be selected for an analog PID or a three-step controller (see •
chapter ╚═▷ “4.4.4.2.2 Configure Power Factor / kvar Control” )
• PF(P) characteristic is available (see chapter ╚═▷ “4.4.4.2 Power Factor Control” ) •
• Beside PF(P) characteristic, Q(V) characteristic is available too (see chapter ╚═▷ •
“4.4.4.2 Power Factor Control” ).
• Reactive power control at the interchange point offers another opportunity of power •
factor control (see chapter ╚═▷ “4.4.4.2.1 Control The Power Factor / Reactive Power
At The Mains Interchange Point” ).
4.4.4.2.1 Control The Power Factor / Reactive Power At The Mains Interchange Point
General notes
Being parallel to the utility, it is desired in some application to control either the power
factor or the amount of imported/exported inductive reactive power in kvar at the mains
interchange point. Similar to an import/export active power setpoint, all easYgens can be
programmed to the same setpoint and will share between each other the reactive power
to reach this setpoint.
The easYgen can work as reactive power control at the interchange point. In this mode
the gensets are monitored and restricted in reactive power flow (outcome and income;
respectively leading and lagging).
