Hi, We too experienced such problem in the past. It might be a servo valve problem or line filter choke. In our case it solved after replaced servo valve. You can try to clean the servo valve filter and see the improvement. best of luck G.Rajesh

CSA, Thank you very much for detailed answer. Well, you have mentioned clearly it can be run on low load. For example, if 100 MW designed machine is running with 1% load (1MW) for continuous one week. Assume grid is disconnected and ISO mode operation supplying only auxiliaries load (it...

CSA, > Do you mean ISOchronous Speed Control mode? Yes > And what condition or event is prompting the question? just to know the effect on the machines, and to know it is good to run or not. Thank you & take care G.Rajesh

Thank you CSA for you valuable feedback as usual. We'll discuss with our team and let you know the outcome. Take care G.Rajesh

Hi, It won't be big task for you to learn GE control system since you had GT experience. Basically once you through about operations it'll be very easy to understand the rung display. You can view the rungs from HMI while unit is running to know the logic status or you can read a...

Thank you CSA & Anon for the feedbacks. We are discussing about 9E machine. We think the answer may applicable for 6B continuous ratchet operation too. Take care G.Rajesh

Thank you all for your useful information.

waiting for the feedback. Thank you G.Rajesh

Very well explained by CSA, thank you take care G.Rajesh

Ayman, Thank you for the feedback. This is what CSA is expecting from all. take care G.Rajesh

CSA /Aymen, Thank you for the DETAILED reply. Yes, we too experienced may problems during the liquid fuel change over test time. We have decided to place a automatic vent valves in the liquid fuel lines. Probably two will be placed, where to install automatic vent valve is being discussed...

CSA, We are not yet purchase the servo valve test kit. It is waiting for budget approval. We'll let you know once it concluded. Thank you G.Rajesh

Very well explanations by all. Thank you for your information. take care G.Rajesh

Hi Raza, Do you have any problem in the GCV operation? OR Are you checking the servo current for experiment? If yes, then CSA already explained lot, please follow it and get it done. Good luck. Take care G.Rajesh

Hi Sd, If you are using old EEPROM's then no need to download the configuration. We had replaced two SDCC cards in past with old EEPROM's after verified jumpers. It's working well. CSA may clarify more. Take care G.Rajesh

Hi, yes ambient temperature will play vital role along with other parameters like 1. compressor washing 2. fuel (gas / liquid) flow 3. exhaust temperature 4. hummudity 5. Atom. pressure many formulas used for calculation, correction factor will be taken based on the performace curve...

Hi, Well said by Mr. Bob Fuel by pass valve (VC3) is full open and caused excessive fuel and over temperature trip. As Johnston said try one false start fire and observe all parameters. If VC3 not closing then change the servo valve and try. Check for the startup permissive and...

Thanks Mesi for your kind feedback. All we are learning form each other. keep it up and keep post your future issues. Take care G.Rajesh
