    for the first time in the web; Here is the MARK 6 turbine control system simulation.

    Hi @godslave42, Thank you for sharing.

    Mark V, C-cores stays at A6

    @WTF? & @White, Problem solved, As per your instructions, I checked "EEPROM DIR T3 C IOCFG" in "R, S, T, C & D" and found recent modifications in C & D IOCFG. I inspected TC2Krept.txt and confirmed that there are "CD-DTBA/DTBB-INV MSK" settings (CIM & CIM_I) that do not match the current IO...

    Mark V, C-cores stays at A6

    Hi, I will check the VR-13 and diesel engine governor areas for any possible cable damage. (No damages found) I will jog (43HR) ratchet and update the results by tomorrow.( L43HRJOG staus changes from 1 to 0) Compared to other units' CD-DTBA/DTBB IO configurator, I found that in this unit...

    Mark V, C-cores stays at A6

    Hi, I have attached some more photos for your reference and will update by tomorrow. (I will try to send clearer photos by tomorrow.) DS200DTBA/DTBB is part of the CD core (so I removed the power supply of DTBA and DTBB to verify the operation). Out of the 3 cores (DTBA, DTBB, and DTBC), only...

    Mark V, C-cores stays at A6

    @WTF? It was noticed that the CD-TCDA card flashing did not match with the other cards. Consequently, it was replaced with a new card, and C successfully transitioned to A7. However, after the C core reached A7, numerous alarms were received and abnormal activity in the Ratchet operation...

    Mark V, C-cores stays at A6

    @WTF? ,@White , The SDCC card from D core was transferred to C and configured (with Voter ID and stage link ID). Initially able to reach A4 state, upon reaching A4 state again, 'EEPROM down T3 C ALL' was performed, enabling it to reach A7. However, upon reaching A7, output control remained not...

    Mark V, C-cores stays at A6

    Recently in our GT (FR6B), the maintenance team replaced the starting diesel engine VR-13 and adjusted the governor. After restarting the unit, during startup, it tripped on an overspeed alarm(the unit did not even reach 2% speed), and the HMI behaved strangely. Consequently, the maintenance...

    Frame 6B Overspeed at FSNL

    @WTF? , @ControlsGuy25 , Problem solved As per your advice, I made a clearness between the GCV valve stem and the GCV actuator rod GCV- LVDTs replaced and calibration and polarity checks were carried out The unit started and it was able to hold speed at FSNL(100.15%) and all other...

    Frame 6B Overspeed at FSNL

    Mark v TMR Vibration sensitivity changed by Control TA, as he wants to use a 200mv vibration sensor in place of 150mv Not sure why they downloaded R core only ( later we performed a download for all (R, S, T) Initially, there was a leak at the GCV -1 stem gland pack and it was rectified by...

    Frame 6B Overspeed at FSNL

    Summary: The unit was shut down due to a Gas Valve Leak (GGV leak), and recently, we reinstalled our gas valve in the turbine and realigned it due to high vibration. Upon starting the unit, it was observed that the speed of the Gas Turbine (GT) did not hold at 100% during the Full Speed No Load...

    GT tripped on FSNL with combustion trouble, exhaust temperature high spread" alarm.

    If FSNL spread reaches more that could be due to one or more liner does not have flame. if possible increase the load, the machine may crossfire after the little loading before going to touch the hardware kindly make sure all instruments(TTXD, GCV, GCV2(IF), and SRV) are okay. what about the...

    GE Mark V <R> reaches A7 although it displays at reset IO CFG failed

    Hi @ AHNIN, I faced a similar problem with one of my frame 6B units (Mark v controller). every time the unit trips, can start the unit normally, and then the unit will trip after some time (5 to 12 hours time delay) with a "LCC No arcnet communication with (R) &Loss of flame trip" alarm...

    Real Power and Reactive Power Load Sharing During Disturbance

    Exactly, (Kindly correct me if I am wrong) Even if GT Droop control (4% droop setting) is active due to GRID frequency disturbance and 25 % of its active load will drop or increase and once the frequency stable is sensed by the TNRL then the governor will take reference from the Pre-selected...

    GE Frame-5 Gas turbine Ratcheting system Hydraulic pressure low Problem

    I guess no need to replace pump with immediately if pressure is low If pressure is low first try to replace FH-1(HR supply filter) Test the integrity of VR-5 verify the limit switches operation ( pump pressure relief valve) If still pressure low then replace FH-5( HR hydraulic supply filter)...

    IGV does not open during acceleration and trips

    what is the hydraulic oil pressure? after forcing relevant logic for calibration did trip oil pressure establish? check Servo coil resistance and check Servo voltage (if servo resistance and voltage are ok then the problem might be from the oil circuit side) did IGV respond while calibration...

    GE gas turbine

    Try to ping (command prompt) between the controllers and HMI and verify the communication stability During ping verify the IP addresses of (R, S, T) Try memory flashing to the controllers
