CGCM-DLR Unit Startup
Verify and Adjust FCR Operation
Follow these steps to verify and adjust the FCR operation.
1.
Select the FCR mode of operation.
2.
Set the FCR setpoint to the generator manufacturer specified no-load
exciter field current.
3.
Enable the CGCM-DLR unit excitation.
4.
Monitor the generator exciter field current, exciter field voltage, and
generator voltage.
5.
Verify that the configured soft start occurs and the generator voltage
increases to near the specified rated output voltage.
6.
Adjust the FCR setpoint and verify that the metered field current responds
as desired.
7.
Adjust gains as required to achieve the desired result.
Verify Metered Voltages and Phase Rotation
Follow these steps to verify metered voltages and phase rotation.
1.
Observe the reported phase rotation for the generator.
2.
Confirm that the metered rotation matches the configured rotation and
that no phase rotation fault exists.
3.
Measure the VT inputs at the CGCM-DLR unit VT input terminals and
verify that they are correct for the selected wiring configuration.
4.
Verify that the phase, line, and average voltages reported in the controller
tags are as expected for the selected configuration.
