CGCM-DLR Unit Configuration
Chapter
4
Excitation Page
The Excitation page is used to configure the unit settings that are related to
operation and protection of the exciter.
•
Soft Start Initial Voltage - The generator voltage setpoint that is applied
immediately after enabling the CGCM-DLR unit excitation output. This
parameter is stored in tag
SoftStart_InitLevel
in the Configuration table.
Its value is a percentage of the nominal generator rated voltage. Take care
to set this parameter higher than the generator residual voltage.
•
Soft Start Time - The desired time to ramp up from the Soft Start Initial
Voltage to the nominal generator output voltage. This parameter is stored
in tag
SoftStartTime
in the Configuration table and is expressed in
seconds.
•
Over-excitation Voltage setpoint - Establishes the over-excitation voltage
setpoint that is used by the CGCM-DLR unit. This setpoint is stored in
tag
OvrExcV_Setpt
in the configuration table and scaled in volts.
•
Over-excitation Time Delay - Establishes the time to annunciate a fault
once the over-excitation voltage setpoint has been exceeded. This setpoint
is stored in tag
OvrExcV_TimeDly
in the configuration table and scaled
in seconds.
TIP
Coordinate the Over-excitation voltage setpoint and time delay
settings with the OEL function settings to help protect the exciter
from overheating while avoiding nuisance tripping from normal
field forcing during transient conditions.
