Kp
0 to 60
2.5
The PID gain for the regulator.
Ti
0 s to 1 min 2.5 s
The PID control integral time.
To turn off the integral component, set Ti to 0. This might cause unexpected regulator
behaviour.
Td
0 to 2 s
0 s
The PID control derivative.
Relay AVR output reactive power parameters
The following table contains the parameters for a relay AVR output that are used during reactive power regulation.
The reactive power regulation parameters define relay regulation when the controller regulates the genset reactive power output.
Configure these parameters under

10
This is the gain for the regulator.
Deadband
0 to 10 %
2 %
The deadband for the regulator, as a percentage of the nominal reactive power.
6.3.4 Reactive power load sharing
During reactive power (kvar) load sharing, the controller uses the nominal voltage as a reference to regulate the AVR output to the
genset. The nominal voltage reference can be adjusted by contributing a weighted amount of the reactive power set point to the
reference value.
Reactive power load sharing can be used in a system where more than one genset is connected to the same busbar section. At
least two of these gensets must have reactive power load sharing activated in order to share the load between them.
All gensets on the same busbar section that have reactive power load sharing active, will share an equal percentage of the load.

Analogue AVR output reactive power load sharing parameters
The following table contains the parameters for an analogue AVR output that are used during reactive power load sharing.
The reactive power load sharing parameters define analogue regulation when the controller regulates the AVR to change the genset
reactive power output for load sharing.
Configure these parameters under
Configure > Parameters > Regulators > AVR analogue configuration > Reactive power load
sharing regulation
