Phase Match Error Upper and Lower Acceptance Limits
These entries are used to specify the upper and lower acceptance limits
for matching Synchronizing Bus phasing to the Reference Bus phasing.
The value is specified in degrees and must be between 0 and
45.
Acceptance Window Delay
This entry is used for the delayed acceptance window method of
synchronization. The value is specified in steps of 0.05 seconds and must
be between 0.00 and 10.00.
Maximum Synchronizing Bus Output Power
This entry is used to specify the power level at which the load sharing
output voltage will be at its maximum value. The ratio of the actual power
output to the value of this parameter is used to adjust the load sharing
output voltage. This value will be specified in kW and must be between 0
and 999,999.
Load Share Full–scale Voltage
This entry is used to specify the load share circuit’s full scale output
voltage. The value is specified in steps of 0.01 volts and must be between
2.00 and 4.00.
Load Share Excess
This entry is used to specify the threshold for initiating action to decrease
the Synchronizing Bus output power to the appropriate portion of the total
system load. The value is a scalar quantity between 0.000 and –0.500.
Load Share Deficit
This entry is used to specify the threshold for initiating action to increase
the Synchronizing Bus output power to the appropriate percentage of the
total system load. The value is a scalar quantity between 0.000 and
+0.500.
