#HAPTER CGCM Unit Configuration
•
Redundant Tracking Delay - This setting adjusts the delay in the
redundant tracking function. This sets the value of the
RedndtTrackDelay tag in the Configuration table, expressed in seconds.
Its purpose is to reduce the likelihood that the short-term response of the
active CGCM unit’s Regulating mode to an upset will be transferred to the
back-up CGCM unit when it becomes primary.
The redundant tracking function performs in a similar fashion to the internal
tracking example above. Increasing the redundant tracking rate makes the
tracking function less responsive to changes in the regulator output by reducing
the slope of the tracking function. Increasing the tracking delay offsets the
tracking response to the right in the figure.
Traverse Rates
These parameters adjust how fast the regulator changes its operating point from
one setpoint, the tracking value, to another when changing regulator operating
modes. In general, the lower the rate, the faster the regulator operating point
changes. A value of 200 puts the regulator in Hold mode and prevents the field
current from changing when the Regulator Operating mode is changed.
Please refer to Chapter 3 for more information.
•
AVR Control Traverse Rate – Sets tag AVR_Traverse_Rate in the
Configuration table. This parameter determines the time measured in
seconds for the setpoint to move from zero to the rated generator voltage.
It determines how fast the regulator changes the voltage setpoint from the
tracking value to the operating setpoint when the Regulator Operating
mode changes to AVR.
•
Power Factor Traverse Rate - Sets tag PF_Traverse_Rate in the
Configuration table. This parameter determines the time measured in
seconds for the PF setpoint to move from 0.50 lagging to 0.50 leading or
vice versa. It determines how fast the regulator changes the power factor
setpoint from the tracking value to the operating setpoint when the
Regulator Operating mode changes to PF.
•
VAR Control Traverse Rate - Sets tag VAR_Traverse_Rate in the
Configuration table. This parameter determines the time measured in
seconds for the setpoint to move from zero to the rated generator KVA. It
determines how fast the regulator changes the VAR setpoint from the
tracking value to the operating setpoint when the Regulator Operating
mode changes to VAR.
•
Manual Control (FCR) Traverse Rate - Sets tag FCR_Traverse_Rate in
the Configuration table. 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.
