Two gas turbines running at 80 percent load 300 MW each then steam turbine output is 310 MW. But at base load when both gas turbines are at 400 MW, more fuel is burning and more exhaust is coming then steam turbine is producing 380 MW while condenser vacuum is according to design value. Why steam turbine is producing 20 MW less than rated output 400MW?
Please remember our boiler feed pumps are VFD drives. Is there any issue at base load or Internal exhust is missing inside boilers? going somewhere? or issue with control valves? It’s triple pressure turbine and running at once through system. Vacuum of condenser is according to design limit.
