•
OEL_En – Setting this tag enables the Over-excitation Limiting function.
•
OEL_Kg - This tag lets you adjust the proportional gain of the
Over-excitation limiter. It also determines the response of the limiter to an
Over-excitation event.
•
OEL_Ki - This tag lets you adjust coarse loop gain and overall gain of the
Over-excitation limiter. This tag determines the characteristic of the
dynamic response to an Over-excitation event.
•
OEL_OnLineHiSetpt – This tag sets the high current level for the online
over-excitation limiting function. The CGCM unit’s over-excitation
limiter limits excitation current at this level. Operation at this level is
allowed for a time no longer than programmed in the
OEL_OnLineHiTimeDly tag.
•
OEL_OnLineHiTimeDly – This tag sets the amount of time the online
over-excitation limiting function lets the unit operate at the excitation
current level programmed in the OEL_OnLineHiSetpt tag.
•
OEL_OnLineMedSetpt - This tag sets the medium current level for the
online over-excitation limiting function. Operation at this level is allowed
for a time no longer than programmed in the OEL_OnLineMedTimeDly
tag.
•
OEL_OnLineMedTimeDly – This tag sets the amount of time the online
over-excitation limiting function lets the unit operate at the excitation
current level programmed in the OEL_OnLineMedSetpt tag.
•
OEL_OnLineLoSetpt - This tag sets the low current level for the online
over-excitation limiting function. Operation at this level is allowed
continuously.
•
OEL_Off LineHiSetpt – This tag sets the high current level for the
offline over-excitation limiting function. The CGCM unit’s
over-excitation limiter limits excitation current at this level. Operation at
this level is allowed for a time no longer than programmed in the
OEL_OffLineHiTimeDly tag.
•
OEL_Off LineHiTimeDly - This tag sets the amount of time the offline
over-excitation limiting function lets the unit operate at the excitation
current level programmed in the OEL_OffLineHiSetpt tag.
•
OEL_Off LineLoSetpt - This tag sets the low current level for the offline
over-excitation limiting function. Operation at this level is allowed
continuously.

•
OEL_Active – This tag is set to 1 when the exciter is operating in the
Over-excitation Limiting mode.
