        CGCM-DLR Unit Operation

Over-excitation Limit

The Over-excitation limit (OEL) operates in all modes except FCR. The 
CGCM-DLR unit senses and limits the field current to prevent field 
overheating. When the limit is reached, the limiter function overrides AVR, 
VAR, or Power Factor modes to limit field current to the preset level. OEL 
operates in the area above the Field Winding Heating Limitation curve in the 
generator capability curve.

The generator operates in one of two different states, offline or online. The 
generator is offline when it is operating in a constant-voltage mode. The 
CGCM-DLR unit is considered online if any of these modes are enabled:

•

Droop (reactive power) compensation

•

Cross current compensation

•

Line drop compensation 

Two OEL current levels, high and low, are defined for offline operation as shown 
in 

Figure 32

. The generator can operate continuously at or below the low OEL 

current level and for a time at the high OEL current level that you configure.
