Gent's,
I hope this message finds you all well.
We have GE Frame 5 gas turbines with Mark V control system. After major overhaul of one unit and during baseload test, the generator output reached:
- 26.1 MW
- 9.3 MVAR
- 0.942 pf
the turbine variables reached:
- TTXM = 474.6
- CTIM = 18.4
- FSR = 85%
- CPD = 9.3 bar
The generator nameplate mentions that generator rating is 25MVA, 20MW at 0.8pf.
We checked the Mark V constants and found that LK90MAX is 43.40 MW. Normally we do not put turbines on baseload. Every few months we put each turbine on baseload for few minutes to take a record of turbine capability.
Is LK90MAX responsible for limiting MW during baseload ? Why it is set too far from the generator rating (25MW at 1.0 pf) ?
What is the philosophy of limiting generator output ?
Thank you
