    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...

    Geneartor not sychronizing Mark-V control system

    @shimat2, check if the unit reaches FSNL. if not refer to @CSA commands(L.O auxiliaries running feedback etc.l52qa) if the unit reaches FSNL check the exciter operation and make sure it is producing 11KV(some units Excitation will start at 14HM) in sync display, check its meet all the required...

    Mark vie -logic names

    I am using GE Markvie . sometimes I used the search option(ctrl+F) to find logic and i noticed some logic search results not found if I enter a name in the search engine with caps lock and others not found if I enter a logic name without caps lock. can anyone tell me what's behind this all?
