• Redundant Tracking Delay - This setting adjusts the delay in the
redundant tracking function. The value of the RedndtTrackDelay tag in
the Configuration table, expressed in seconds, is set. Its purpose is to
reduce the likelihood that the short-term response of the active
CGCM-DLR unit Regulating mode to an upset is transferred to the
back-up CGCM-DLR unit when it becomes primary.
The redundant tracking function performs in a similar fashion to the internal
tracking example in
makes the tracking function less responsive to changes in the regulator output by
reducing the slope of the tracking function. An increasing in 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 regulator operating modes
change. 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.

• AVR Control Traverse Rate – Sets tag AVR_Traverse_Rate in the
Configuration table. This parameter determines the time that is 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 that is 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 that is 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 that is
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.
