Chapter 4 CGCM Unit Configuration
Under-voltage
• Setpoint - Establishes the under-voltage setpoint used by the CGCM unit.
This setpoint is stored in tag Undr_V_Setpt in the configuration table
and scaled in per cent rated generator volts.
• Delay - Establishes the time the generator voltage must be below the
under-voltage setpoint before the CGCM unit annunciates an
under-voltage fault. This setpoint is stored in tag Undr_V_TimeDly in
the configuration table and scaled in seconds.
Compensation Settings
• Droop Percentage - Establishes the voltage droop level at rated load when
operating in Voltage Droop (reactive current compensation) mode. This
setting determines the change in voltage setpoint expressed in percent of
rated voltage. A setting of 5, for example, results in the voltage setpoint
being changed by 5% of rated voltage for a change in kVARs equal to the
rated kVA. The tag V_DroopSetpt in the Configuration table stores this
parameter.
• Line Drop Voltage Compensation - Establishes the output voltage increase
at rated current. Tag LineDropComp in the Configuration table stores
this parameter.
