What is/are the limitation of the GE PFR? Presently, our GT baseload is around 235 MW with these kind of ambient temp and humidity. Example my GT at 200 MW PSL and a big power station tripped which cause the grid frequency to fall from 50 hz to 48 hz (just to exaggerate things), does my GT will pickup up to baseload only (temp control) am I right? TTRXB/TTRX are 656.6oC and 648.9oC respectively for maximum limit (Isothermal). TTRXB/TTRX is 610oC during baseload.
Why there is no more Peak load selector in our plant? In my previous experience in a 32 MW GE gas turbine Mark IV, we have PSL, Baseload and Peak load selector. During baseload, exhaust temp was 560oC and if I remembered it right at peak load, exhaust temp setpoint was 580oC. (12 years ago).
Another situation, If my GT is at 70 MW PSL, and suddenly too many feeders tripped (again let's exaggerate things), grid frequency will increase too much. Does my GT will trip on reverse power cause it will try to regulate the frequency? Or it will limit only to minimun load of 25 MW? 25 MW is the minimum load (Spinning reserve as per GE definition) during start up. I can see in RUN status: Spin_Res.
What is the meaning of Secondary Frequency Response (Regulation)? Does all GE gas turbine have this kind of control?
Thanks.
