Var Control
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The var control adjusts the generator voltage to maintain a constant reactive power (kvar) load on the generator
throughout the kW operating range. This assures sufficient excitation of the generator field under all load condi-
tions. A setpoint is provided to set the desired VARs. The var control function may be enabled with VAR PF con-
trol mode selection setpoint (parameter 7558). The setpoint can be configured via ToolKit.
NOTE
Whether var control or power factor control is enabled, internally the var setpoint for the generator is
restricted from +100 % to -10 % rated reactive power. When the DSLC-2 is operating in the base load
mode, process mode or with an active MSLC-2 control, it will not allow the kvar output of the generator
to increase above 100 % or below -10 % of the Generator rated reactive power (parameter 1758).
