Hi!
I 'am very please if anyone could share same experience or advice related to the problem in Mark IV gas turbine generator control. We have Frame5 P for generator drive control by Mark IV speedtronic. Recently we face generator breaker open after few hours/day of unit running by reverse power. Our investigation to the problem found that this reverse power due to 2 co incident of problem related FSR.
1. Computer "T" problem, indicated by Red Activity LED was Off after reaching FSNL & FSRACC freeze at 16%
2. FSRACC in Computer "S" (Computer "R" was OK) ramp down to 17-19% /below Full speed no load FSR (FSR FSNL 20%)& recover above FSNL FSR
Related to the item #1 finding we already change HMPF card in Computer T, HCMA card in comp "C", try to disconnect card except HMPF, HXPD & HAIC & even replaced all card in comp T, but problem still remain
Related to the item #2 finding, we suspect this is related to the HMPF card due to some time FSR ACC in computer "S" only that drop below FSNL FSR. but problem still remain after replacing this card.
many thanks for any feedback.
