Hello:In my working place we have 3 turbines SGT 300, driven unit is power generator, these turbines sharing the power output, usually 2 turbines are running and the other is standby. There is a problem with these turbines, the problem is power imbalance, meaning that in sometimes a power output imbalance occur, in one turine the generator power output suddenly inceasing and the power of the other generator decreasing and this power imbalance causing trip of the turbine which its power output increased, it trips with alarm COMBUSTION CAN FLAME FAIL , also tempreature deviation occurring.
Please can you advice what possible reasons for this power imbalance?
Thank you
