Frequency Match Proportional Gain
The Frequency Match Proportional Gain adjusts the
Speed Bias by an amount that is directly related to the
difference between the generator frequency and the bus
frequency. The speed bias is adjusted in the direction
that should decrease the difference between the
generator and the paralleling bus.
Range: 0.01 – 100.00
Default: 1.00
Frequency Match Integral Gain
The Frequency Match Integral Gain adjusts the Speed
Bias at a rate that is related to the difference between the
generator frequency and the bus frequency. The speed
bias is adjusted in the direction that should decrease the
difference between the generator and the paralleling
bus.
Range: 0.01 – 100.00
Default: 1.00
Frequency Match Derivative Gain
The Frequency Match Derivative Gain adjusts the
Speed Bias by an amount that is related to the rate of
change of the difference between the generator
frequency and the bus frequency. The speed bias is
adjusted in the direction that should decrease the rate of
change of the difference between the generator and the
paralleling bus.
Note: This gain is set very low from the factory, but may
be needed to track the bus if the load on the bus is
changing often.
Range: 0.01 – 100.00
Default: 1.00
Phase Match Proportional Gain
The Phase Match Proportional Gain adjusts the Speed
Bias by an amount that is directly related to the phase
difference between the generator L1-L2 voltage and the
bus L1-L2 voltage. The speed bias is adjusted in the
direction that should decrease phase angle between the
generator and the paralleling bus.
Range: 0.01 – 100.00
Default: 1.00
TP-6953 7/19
Phase Match Integral Gain
The Phase Match Integral Gain adjusts the Speed Bias
at a rate that is related to the phase difference between
the generator L1-L2 voltage and the bus L1-L2 voltage.
The speed bias is adjusted in the direction that should
decrease the phase angle between the generator and
the paralleling bus.
Range: 0.01 – 100.00
Default: 1.00
Phase Match Derivative Gain
The Phase Match Derivative Gain adjusts the Speed
Bias by an amount that is related to the rate of change of
the phase difference between the generator L1-L2
voltage and the bus L1-L2 voltage. The speed bias is
adjusted in the direction that should decrease the rate of
change of the phase difference between the generator
and the paralleling bus.
Range: 0.01 – 100.00
Default: 1.00
Fail to Sync Delay
The Failure to Synchronize merely indicates that a
generator was not able to synchronize within the
expected synchronizing time. This warning on a
generator in Generator Management will cause another
generator to start if it is available, but will not cause the
first generator to stop synchronizing.
Range: 10 – 600 sec
Default: 300 sec
Dwell Time Remaining
This parameter displays the remaining time for the dwell
timer in seconds. The generator is considered to be in
Sync when the dwell timer expires. If this value is
resetting to the Dwell Time (directly above it in
SiteTecht), the generator is not holding synchronism.
This value is only updated when the controller is
synchronizing (Synch Mode = Active, Passive or Check,
breaker is open, generator is running).
Note: Early firmware versions for the Decision-Makerr
3500 controller do not support this parameter
(there is no value populated for it).
