Appendix E Detailed CGCM Unit Tag Descriptions
AVR Mode Outputs from the CGCM Unit
The AVR mode has one output.
• AVR_FCR_Selection – This tag reports the selection of AVR or FCR
control (see AVR_FCR_Select).
FCR Mode This section describes the FCR mode inputs and outputs for the CGCM unit.
FCR Mode Inputs to the CGCM Unit
The FCR mode has these inputs:
• AVR_FCR_Select – This tag lets you select AVR or FCR control.
• FCRSetpt - This tag sets the desired field current setpoint for operation in
the FCR control mode.
• AVR_FCR_Kp - This tag sets the Proportional Gain parameter for AVR
and FCR control modes
• AVR_FCR_Ki - This tag sets the Integral Gain parameter for AVR and
FCR control modes.
• AVR_FCR_Kd - This tag sets the Derivative Gain parameter for AVR and
FCR control modes.
• AVR_FCR_Td – This tag sets the filtering Time Constant for AVR and
FCR control modes.
• FCR_Kg - This tag lets you adjust coarse loop gain and overall gain of the
FCR operating mode. It also determines the characteristic of the dynamic
response to a change in the CGCM unit’s output current.
• FCR_Traverse_Rate - This parameter determines the time measured in
seconds for the setpoint to move from zero to the rated exciter current. It
determines how fast the regulator changes the field current setpoint from
the tracking value to the operating setpoint when the Regulator Operating
mode changes to FCR.
• AVR_FCRAuxGain - This tag lets you adjust the overall gain of the
auxiliary input’s control on the AVR/FCR operating mode. The units for
this are percent of nominal per volt. A setting of one results in the
controlled parameter being changed by one percent of the nominal value
for each volt applied to the auxiliary input.
FCR Mode Outputs from the CGCM Unit
The FCR mode has one output.
• AVR_FCR_Selection – This tag reports the selection of AVR or FCR
control (see AVR_FCR_Select).
