What glenmorangie said. I think. I don't really understand the scenario; and I've never seen both an AC and a DC turning gear motor on a GE-design Frame 9E heavy duty gas turbine. (GE Belfort does ... unusual things from time to time (for no other than simply because they can).) As glenmorangie...

I wasn't writing specifically to you, Curious_One; I was kind of just saying this poster is ... unusual. By which I really meant new. And I was really trying to get him to be more specific. Your answer was spot on; nothing wrong with it. And, there is the English language thing to try to...

gubavac111, We don't know exactly what was done during the overhaul of the gen-sets, so it's difficult to say if anything which might have positively affected the operation was done. And, you mentioned that some tech was onboard and made some adjustments to some other piece of equipment...

PUT in situations, or did they take the position thinking they would get some OJT (On-the-Job-Training) and experience and didn't know what they'd gotten themselves into? I would posit that a big part of the problem is that Managers expect too much from automation, because salespeople and other...

jackson has a couple of different sites and scenarios. One with one GT and one with two GTs....

jackson, You neglected to say if the site uses any kind of power management system (sometimes called a PMS) or some kind of "load sharing" control system. The explanation below presumes NO power management system OR "load sharing" system--just a unit operating in Isochronous Speed Control and a...

WOW! The old-timers are coming out of the woodwork! Good to see you're back, MIKEVI and long time no hear, glenmorangie. Unless the original poster can tell us why the unit tripped, we are all just speculating. EVERY condition that causes a GE-design heavy duty gas turbine to trip has an alarm...

Mr. Ray, Pray tell, sir: What unit are you working on, and when was it installed/commissioned? And, has the turbine control system been upgraded since installation/commissioning? What is the current version of turbine control system in use on the turbine-generator? Does the turbine have a...

Curious_One, There is a DLN-1+ system from GE. It uses a continuous emissions monitor system to provide information to the Mark*. I don't have any experience with it, but I hear it provides very low emissions levels (low single digits, I'm hearing). I don't anything more about it...

Curious_One, Many units (particular non F-class units) do not have IBH even if they have DLN-I. Again, it's main purpose is to provide more "turndown" (a larger Premix Steady State operating range of load). A lot of unmanned sites are peakers--meaning they run at or near Base Load when they run...

Dan Raye, The unit must probably operate at or near Base Load most of the time? That seems an odd reason to "deactivate" IBH (because the incoming air is dry and less dense). I presume the ambient air temperature must never get too much below the ISO temperature rating (on the turbine...

User007, An advanced degree will usually offer you more "exposure" because some employers are only (foolishly) looking for people with a certain level of degree as a minimum for the position(s) they are offering. Also, it's likely that in the course of obtaining your advanced degree you will...

Ken Symmons, I didn't answer the questions about format.... For Mark V, when you copy the directories and their contents to removable media they will include a LOT of ASCII text files--which anyone can open and view with any basic text editor (think MS-Notepad, or even MS-Word (just don't make...

Ken Symmons, Er, ..., Um, ..., Why can't the (over-paid) SME tell you how to get the information they need.?.?.? It would seem if they have the information they gave you, for the tidy sum you are paying them they should be able to tell you how to obtain it. But, I digress. Again. We would have...

SaberMPS, To begin with, you wouldn't be just buying third-party software--you would be buying hardware, programming software, configuration and programming by some company (usually called a 'control system integrator'), removal of the existing turbine control system hardware, installation of...

CAPRAEZ, EVERY potential control system supplier is going to say the same thing. They all believe their automation system is better than what's currently installed--or at least they want potential buyers to believe that. Unless they have extensive experience with combustion systems and fuel...

CH Lee, gubavac111 took the vessel to shipyard, and they did nothing about the issue and his contract was over. He's moved on to other endeavours. This thread is "closed." And if you read through the whole thread you will see we had a discussion about terms and usages.

stevesummers, You would do well to remember: This is a technical forum. Being specific is more than just kind of important. AND, I am not James (ControlsGuy25)—and that’s even more important.

Steve summers, Wow. By “Gas engine” are you referring to a reciprocating engine burning natural gas or perhaps even liquid petroleum gas (sometimes referred to as LPG)? Or are you referring to a reciprocating engine burning gasoline?

Does Woodward use MOOG Windrive?
