Hi all,
I'm hoping someone here can help me with an issue we here at my plant have recently encountered. We operate 7FA turbines. While shutting down a unit the P2 pressure started to hunt from 350-450 PSI (typical P2 pressure is 400 PSI) while the unit was at ~10 MW's. Unit MW output started to hunt from 5-20 MW's, and the GCV's appeared to be cycling. After a few minutes of this, the unit eventually did shut down normally.
Is anyone able to help me at least begin to troubleshoot this issue? I would greatly appreciate it, and I thank you in advance.
