Good day all

I am looking for some documentation support (Installation & Commissioning ) for HDGT GE frame 7E.

Thank you for your attention and reply,

Regards,
James

 

James,

As recently as a couple of years ago EVERY HMI shipped with a GE-design heavy duty gas turbine controlled and protected by a Mark* VIe had multiple folders (directories) of documentation for Mark* VIe AND a whole bunch of other GE control systems and applications (think wind turbines, exciters, static starters, etc.). All one had to do is go "rummaging" through the hard drive to find the folders which have hundreds of .pdf files--all of which have only the GE publication number as the filename. There were even documents called "GE How-Tos" (GEHTs!) about some of the individual processes and activities--a LOT of them. They were pretty brief, and a little lacking, but someone felt they were necessary and almost NO ONE knows about them.

If it's just documents about the various components and functions of the Mark* VIe, you will find LOTS of them. I suggest two things as you go through the various folders and open each .pdf file to see what it's purpose is. First, create a folder somewhere (desktop; flash drive; hard drive) and copy relevant document files to that folder. THEN, rename the individual document files to include the title of the publication--making it easier to find them later. I also suggest making a table/list of all of the documents you copied, with the GE publication number, and the document titles, so that you can refer to it later as well.

If you're looking for something to tell you how to commission a Frame 7E, there was an attempt to do something like that many years ago, but it was never completed--because it's a huge undertaking and it really is specific to each machine and it's fuel and options and combustion systems and auxiliaries. And, trying to make a generic document--even for just one Frame size machine--is a huge undertaking.

And, say, by some miracle, such a document was made for one machine and its fuels, options and auxiliaries. As auxiliaries change and fuels change and components change who will update the document for each successive machine with different fuels, options and auxiliaries, combustion system, sensors, even ARES (Adaptive Realtime Engine Simulation--also know as Model-Based Control, and its changes and enhancements and improvements)?

That's right--no one. One division of GE makes the Mark* turbine control systems and HMIs, and another system programs them, and another division packages the Mark* with the turbine, generator and auxiliaries--and none of them believe it's their responsibility to document how the turbine operates and is controlled and protected using the Mark*. Or, how to commission the machine/package properly and document it properly.

It's a real conundrum.

I hope that things have changed since I left the field of commissioning, maintaining, upgrading and training. I hope I'm wrong and there is some kind of effort underway to document commissioning, operation and maintenance.

And if wishes were nickels, I'd be a very, Very, VERY wealthy man. I am rich--I have my health, a lovely life partner and a dog, and I want for nothing. So, monetary wealth is secondary to me at this point in my life. I just hope I can keep what I have, protect the ones I love (without having to use guns), and die a peaceful death in my sleep. And that's a very dubious thing at this time in the world today.

We now return to our regularly scheduled programming.

@WTF?

I thank you for these valuables informations

I will follow these instructions and come back here if i have questions .

Stay safe & blessed

James,

Best of luck! There might be some people reading this thread who can offer some procedures for some loop-checks or LVDT feedback calibrations.

If you find something more, please share it with the forum!

 

@WTF?

Thank you for this kind message.

I will update here on what i will find when i will be in the field for commissioning these 3*Frame7E.

Best regards,
James
