I am operating 2 PG6581B gas turbines in combined cycle mode. At part load the speed FSR is lowest value, however HMI indicating IGV temperature control. Why?
What curve are we operating on at part load if not the CPD-Temperature curve?
What curve are we on when peak load is selected?
The isothermal constant is set at 615C, should the high exhaust temperature and over temperature trips be above this value?
