Thank you for the feedback!

glenmorangie, I wholeheartedly agree it's not a problem with P2 pressure. SRV control and SRV LVDT calibration aren't likely to be the cause--it's most likely a problem with the fuel supply--plugged strainers, low fuel supply pressure, something like these are most likely the cause. And that...

saurabhstalone, This sounds like some field modification to the basic automatic synchronization logic--and a bad field mod, at that. If the breaker is being closed/synchronized automatically, what's supposed to happen if the AutoSynch logic is in the Speedtronic turbine control is that the...

Mully, The best place to look for information about a block used in Mark VI application code would be to right-click on the block in Toolbox and then click on 'Block Help.' That would pull up a Help file for the block which will describe all of the inputs and outputs and the function of the...

ThirstyMonkey, You're very welcome, and I'm glad to have been of help. Base Load refers to rated load of the prime mover (the steam turbine or gas turbine) which drives/provides torque to a generator. A machine (generator set--prime mover and generator) is rated based on the power output...

I don't have any experience with PFR on steam turbines--it sure seems like it would be applicable to a steam turbine, and it wouldn't have to be used only in power (load) mode. It's important for all prime mover governors to respond appropriately to grid frequency disturbances no matter the mode...

rak11226, Ah, the infamous "load throw-off" test. Always loved performing those (NOT!!!). There's just too much about the circumstances of the testing that we just don't know. Did you open a breaker supplying the grid from the plant? Did you open one of the turbine-generator circuit...

ThirstyMonkey, You didn't say if the steam turbine has controlled or uncontrolled extractions. This can have a very large effect on how the steam turbine is to be operated. >What would be the scenario(s) when a steam turbine is >manipulated to operate in a pressure control mode, and in a...

Terence Sundgren, First of all, let me say that most utilities would have a conniption fit if anyone did this at their home without any electrical protections on the generator-set. Second, I presume the theoretical generator is directly coupled to the petrol engine--meaning that when the...

Safety Instrumented Systems (SIS) and SIL (Safety Instrumented/Instrumentation Level) are some very expensive guidelines. The control system used in a SIS may be SIS-capable (at various levels, SILs) but a true implementation of SIS involves a deeply detailed investigation of all aspects of the...

Maaz Naseer, Over-frequency occurs when there is too much generation for the existing load. So, the best cure for a problem like this is a power management system which will very quickly reduce the load of the droop machines while keeping the Isoch machine above the reverse power setting...

andstennett, My condolences on the upgrade. Go to Settings in MarkV Studio, and make sure TCI is selected (has a check-mark to the left). Then click on configuration (under Settings) and click on the TCI tab. It should show "Global System v13.1" and "DataDictionary v9.0". You may...

When did this problem start? Had the in-house machine been working properly and then it started tripping? Was new in-house load added to the facility, perhaps with a different power factor? Was the reverse reactive power relay recently "calibrated"? Reactive power is a function of the load...

Dear Sir, The Belfort (France) division of GE has responsibility for GE-design Frame 9E heavy duty gas turbine and they have demonstrated a tendency to change and modify long-standing control philosophies and practices. Your use of the signal name TMGV indicates they have begun to use torque...

grajesh, Did the articles you read not provide part numbers? If I recall correctly, Microswitch is a brand name (manufacturer based in the USA). And I just used my preferred World Wide Web search engine and Crouzet (a French-based manufacturer) also manufactures/sells "microswitches." So...

Thank you for the thank you. Were you successful?

samson16, Have you tried using the 'Help' feature of Toolbox? There should also be a Documentation folder somewhere on the VM (Virtual Machine) that holds all of the GE documentation. It's kind of cryptic because only the publication numbers are listed in the Folder contents, BUT only can...

niazbibiyana, Thanks very much for the feedback. You haven't said which temperature increased, or if the two increased but that one increased more, or if one decreased more than the other and both decreased slightly.... There are very many different scenarios (read below) and information like...

khairulsulaiman, Not a crack along the edge of the welded-on cooling water jacket? Most of the aft support legs I've encountered on GE-design heavy duty gas turbine have all been "cut" from a single piece of metal, with a jacket welded on the outside face to which cooling water is piped...
