Hi dear Control specialist
this is my 1st message and i'm glad to find this useful forum.
In our power plant we have 6 seimens SGT200 gas turbine. one of them has a strange problem. after starting turbine and running for a while ,between an Hour or Days, suddenly turbine trip with flame fail message: "flame fail, temp. falling throttle opening" or "flame fail, temp. falling throttle opening".
in data log we found that gas pressure after regulator drop Approx. 3Barg in 0.2 second.
we checked all fuel parameters and element for example gas regulator, Press. Transmitters, I/P converters, fuel valve actuator, VGV ,gas Block valves, speed sensors and ... but nothing found!
Do u have any suggestion or same problem?
Control system is mark II.
thank u for your cooperation
Have nice time
