5.6.1.2 VOLTAGE AND REACTIVE (KVAR) POWER CONTROL
Constant Reactive Power Mode (Default)
This is the default mode of exporting power to the mains (utility); where the DSE load share controller
holds the amount of reactive power produced at a constant level. The amount of reactive power
produced by the generator is irrespective of the load level or any other parameter.
The amount of reactive power produced is defined as Maximum kVAr Level and is set using either the
DSE Configuration Suite PC Software, Front Panel Running Editor, in PLC Functions, or via Modbus
messages.
The user has the option to limit the amount of reactive power the generator produces to within their
power factor depending on the amount of active power produced. Regardless of this option, the
generator does not produce more than its rated reactive power.
Constant Power Factor Mode
In this mode of exporting power to the mains (utility); the DSE load share controller varies the amount
of reactive power produced with regards to maintaining the required power factor.
This mode allows the generator to maintain a constant export power factor if so required.
The required power factor is set using either the DSE Configuration Suite PC Software, Front Panel
Running Editor, in PLC Functions, or via Modbus messages.
Voltage - Reactive Power Mode
In this mode of exporting power to the mains (utility); the DSE load share controller varies the amount
of reactive power produced with regards to the Control Curve depending on the measured voltage.
This mode allows the generator to support the mains (utility) voltage stability by monitoring the voltage
and changing the amount of reactive power produced.
Power - Power Factor Mode
In this mode of exporting power to the mains (utility); the DSE load share controller varies the amount
of reactive power produced with regards to maintaining the required power factor. This power factor is
derived from the averaged power using the Control Curve.
This mode allows the generator to support the mains (utility) stability by varying the power factor
depending on the produced active power.
