ESKAY, You're welcome, and thanks for the feedback. 'Feedback is the most important contribution!'(c) at control.com.

One more thing about diesels: The color of exhaust smoke can be very telling about the condition and/or the load of the diesel. White smoke means incomplete combustion, as in poor injector condition, or bad rings, or low compression. Heavy dark smoke indicates excessive load. This quite...

If you're having specific issues it would be best to list them to get help. This is an extremely generic question and we can't provide much help without more specific information. In theory, the A-B should have been programmed to make the turbine and its auxiliaries operate exactly the same...

We don't know the age of the diesel, how recently it was refurbished (if ever), or the age of the torque converter or how recently it was refurbished, if ever. Most older diesels used a hydraulic solenoid/cylinder arrangement to set diesel speed. The control was entirely open loop (meaning...

ESKAY, When you find the file using DIR in the F:\UNIT1 directory, what is the date/time and size shown for the file? A typical TC2KREPT.TXT is usually approximately 100-200 KB in size. Unless someone manually edited TC2KREPT.TXT to add the contact input you mentioned, it will most likely...

The "short" answer to this question is that the internal hot gas path components will not, and cannot be expected to, last as long as if the unit were being operated with the normal control parameters. How much degradation while the hot gas path parts experience? That's anyone's guess...

ESKAY, You've written about this particular "problem" here before. You write about a LOT of problems here. And you provide virtually <b>ZERO</b> feedback when asked for more information, and even less feedback as to whether or not you find the information provided useful or not. I...

This is a great question for the GE Controls Connect site. Here is a link to a thread with the site's URL: http://www.control.com/thread/1326644263#1326725980 [Remove any spaces inserted by the forum software.]

I have a cent's-worth of advice here, having been through some HMI- and control system development projects over many years. An HMI is not a control system. It is a window into what the control system is doing, and it can be used to program the control system that is controlling the prime...

This is somewhat unusual. There could be several reasons for an increased card failure rate, but since that doesn't seem to be of concern there are at least two sources of Mark IV Speedtronic cards: GE, and Gas Turbine Controls Corporation (GTC). Yes; GE appears to be still selling...

Please help us help you by providing exact information about which input needs to be changed (terminal board; terminals; signal name; etc.); its current configuration, and what its new configuration needs to be. And in the future, please provide as much information in your original post as...

Sunil, >... I have written it should be higher before synchronisation, not after. That may have been what you meant, but that's not what you wrote. "<i>You have to keep the new generator frequency slightly higher than the running generator to share some load.</i>" Share is not the...

>... you can raise/lower "Speed" by changing TNRI set point in > the band of 97 % to 101 %. TNRI is the Isochronous Turbine Speed Control Reference, and it's changed using the same RAISE- and LOWER SPD/LOAD buttons/switches as when operating in Droop Governor Mode. But, if one changes the...

> You have to keep the new generator frequency slightly higher than the running generator to share some load. Wrong. Wrong. Wrong. The magnetic forces at work in synchronous generators keep them <b>synchronized</b>. Induction machines require slip (speed differential) in order to...

First of all, it should not be possible to operate a machine and a load independent of other machines (in "island" mode) in Pre-Select Load Mode. The Speedtronic should be in Isochronous Governor Mode and that will adjust the fuel to maintain frequency regardless of the load. You can't tell a...

The governor of the prime mover driving the load should be in isochronous mode, meaning it will adjust the energy input to the prime mover to maintain a frequency setpoint regardless of the load--up to the rated power output of the prime mover. If the load increases, from say 64% of rated to say...

I'd say this falls under the 'Loss Prevention Department', for certain! I'm presuming we're talking about Electro-Static Discharge ESD here.?.?.? And, just out of curiosity, is someone (who?) trying to sell this? What does your insurance company say about this?

We haven't heard back from the original poster. And, this isn't technically "Trip Oil" pressure we're talking about here; it's just part of the Trip Oil pressure circuit and it only applies to the IGVs in this case and the IGV Dump Valve. It <b>IS</b> necessary to have 20TV-1 energized (and...

otised, Methinks he wanted to know how to change the turbine speed while in Pre-Selected Load.... Otherwise, the answer was completely correct.

When posting a question like this, please post more of the "context" of the question. For example, what is the frequency differential, what is the need for connecting two generators in parallel with each other and operating at different frequencies? Have you tried this successfully or...
