Dear Experts..
I work in a CCPP which have two F9E and MS9001 GTs. We have a problem related to operation SRV valve in our GT. GTs work under Mark V control. Can you please help us?
During few days We had a problem in GT. There was fluctuation in P2 gas pressure. It had changed from 19 to 20.8 bar. But We were still in the work. We haven't stopped GT.However last night while load decreased from the GT, Load and gas pressure suddenly started too much fluctuation in GT (from 17 to 24 bar. We stopped load decreased and then We increased to BASE LOAD. We saw that SRV full opened and P2 pressure 24.4 bar (this pressure is gas station output pressure). It still works GT and P2 pressure stable but 24.4 bar. After from GCV, gas pressure is 15.8 bar.
SRV current value is;<pre>
FPRGOUT : 20.15 bar FPRG_INT : -100.00 %
FSGR : 104.9 % FPRG_CNV : -100.00 %
FAGR : 88.42 %
FPG2 : 24.41 bar</pre>
What may be problem in SRV? How to can be repaired? Thank you for your help..
