Gener protect

Hint:
Generator protections are ignored when Process control: ProtectionMode = NOT ACTIVE. This is important
in the case the GCB and engine is not controlled from controller.
The content depends on programmable protections (Universal states) settings. This list contains pre-set
protections from default archives + fixed protections, which are always present.
Electric protection are evaluated when LBI:ReadyToLoad=1 and max stab time was finished.
OverldStrtEval
Specifies the overload level, where the protection evaluation starts (see figure at 2PovrldStEvDel). Under
this level the protection is not active.
Step: 1 % of Nomin power
100 – 200 %
Range:
Force value: Yes
2POvrldStEvDel
IDMT curve shape selection. 2PovrldStEvDel is the Reaction time of IDMT protection for 200% overload
Pgen = 2* OverldStrtEval.
Step: 0,1 s
Range: 0,0 - 600,0 s
Protection: BreakerOpen & Cool-down.
IDMT is inverse proportional to the generator overload. The higher the overload gets the less time will elapse
before the protection activates.
When the IDMT protection is activated the GCB is opened, the event is recorded in the Alarmlist and History,
and the engine will cool down and stop.
