In our plant there are four frame 5 turbocompressor unit , sometimes during starting the gt we face a problem on antisurge . Anti surge goes to saftey protection and hp rotor speed stays on 4700 and does not accelerate to reach 5100 rpm , igv status is full open , there is no alarm on alarm screen .
I attached some some screenshots while igv is full open and speed is 4700 or 93%.
I cant understand why speed does not increase and what is the reason so cant find any solution for it.
Any help would be greatly appreciat.
