Dear CSA,
Thanks for your all valuable replies asked by me related to Gas turbine. You are doing best job on global forum which is helping to many peoples. One problem i am facing in our machine.
Gas turbine Frame-V with control system Mark-Vie is running on 4 MW load. Normal speed is 5120 RPM.Inter valve FPG2 pressure: 15 Kg/cm2.
Problem: machine speed is hunting 5100-5120 RPM intermittently (2-3 Times in two days). subsequently inter-valve pressure also hunting 14.1 to 15 Kg/cm2 and inter-valve pressure low alarm L30FPG2L_ALM appeared. Speed/load raise/lower command went as per speed signal.
Load remains constant.
63FG calibrated and found ok.
Kindly guide me.
