D Reactive Power Sharing Proportional Gain
The Reactive Power Sharing Proportional Gain
determines the contribution of the reactive power
sharing proportional term to the voltage bias. The
proportional term is directly related to the difference
between the average percent reactive loading of all
gens on the bus and the percent reactive loading of
this individual generator. The proportional term
increases the voltage bias when the average bus
reactive load is greater than the generator reactive
load.
Range: 0.01 – 100.00
Default: 1.00
D Reactive Power Sharing Integral Gain
The Reactive Power Sharing Integral Gain
determines the contribution of the reactive power
sharing proportional term to the voltage bias. The
integral term ramps at a rate related to the difference
between the average percent reactive loading of all
gens on the bus and the percent reactive loading of
this individual generator. The integral term increases
the voltage bias when the average bus r eactive load
is greater than the generator reactive load.
Range: 0.01 – 100.00
Default: 1.00
D Reactive Power Sharing Derivative Gain
The Reactive Power Sharing Derivative Gain
determines the contribution of the reactive power
sharing derivative t erm to the voltage bias. The
derivative term is related to the rate of change of the
difference between the average percent reactive
loading of all gens on the bus and the percent reactive
loading of this individual generator. The derivative
term increases the voltage bias when the generator
reactive load decreases relative t o the bus reactive
load.
Range: 0.01 – 100.00
Default: 1.00
D Voltage Trim Proportional Gain
The Voltage Trim Proportional Gain determines the
contribution of the voltage trim proportional term to
the voltage bias. The proportional term is directly
related to the difference between the target voltage
bias (which offsets the reactive droop) and the actual
voltage bias. The proportional term increases the
voltage bias when the voltage bias is lower than the
target.
Range: 0.01 – 100.00
Default: 1.00
D Voltage Trim Integral Gain
The Voltage Trim Integral Gain determines the
contribution of the voltage trim integral term to the
voltage bias. The integral term ramps at a rate related
to the difference between the target voltage bias
(which offsets the reactive droop) and the actual
voltage bias. The integral term increases the voltage
bias when the voltage bias is lower than the target.
Range: 0.01 – 100.00
Default: 1.00
D Voltage Trim Derivative Gain
The Voltage Trim Derivative Gain determines the
contribution of the voltage trim derivative term to the
voltage bias. The derivative term is directly related to
the rate of change of the difference between the
targetvoltagebias(whichoffsetsthereactivedroop)
and the actual voltage bias. The derivative term
increases the voltage bias when the voltage bias
decreases.
Range: 0.01 – 100.00
Default: 1.00
