Gas Turbine PT Speed Fluctuating
Gas turbine PT speed fluctuating and synchronization problem

Hello,

I have a problem with MAN THM 1304-10AP gas turbine, so that when gas turbine-generator is idle and self sustained power turbine speed fluctuates and can't be synchronized. So that winner shifts from PT controller to GG controller because of low limit speed of GG. IGV and bleed valves are adjusted and operating correctly. This problem occurs in %80 of start ups.

Please tell me if you have any ideas about this problem.

Hello,

Is the unit mechanical governed, or electronically?
