Undervoltage
•
Setpoint - Establishes the undervoltage setpoint. 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
undervoltage setpoint before the unit annunciates an undervoltage 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 that is expressed in
percent of rated voltage. A setting of 5, for example, results in the voltage
setpoint changing by 5% of rated voltage for a change in kVAR 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.
