GEH-5980, Speedtronic Mark V Maintenance Manual, Sect. 4.4, 4.5, and 4.6 has some very good clues as to what many of the files do. TC2KREPT.TXT is just an ASCII text file that was produced when the unit-specific software was written to list what inputs and outputs were connected to which I/O...

ITS - Integrated Temperature Sensor It was a digital, microprocessor-based control system module that was added to the Mark II product line late in the manufacturing period. It replaced a lot of potentiometers and some analog circuit cards in the Mark II. It was primarily an exhaust...

It seems you are asking what happens when a generator and some load (the "island") are isolated from a larger grid. For example, let's say a generator and it's prime mover (a turbine or a reciprocating engine, for example) are rated at 20 MW, and the load of this small "island" that can be...

It's presumed since you posted in a Mark V-related thread that you are looking for Mark V Speedtronic OEM parts. We recommend patronizing advertisers here on control.com, and Gas Turbine Controls (www.gasturbinecontrols.com) advertises they have Speedtronic parts and are now offering control...

You need to jumper a good pick-up to <S>'s input after you disconnect the wires of the bad pick-up from <S>'s input. Be aware that while doing this if <R> or <T> loose their feedback while you are trying to jumper the signal over to <S>, the unit will likely trip anyway, probably because of...

Again, I'm not familiar with steam turbine control schemes, and I don't have any steam turbine software to try to look at. I am guessing (!) but I would imagine that there's some kind of Speed/Load Raise and -Lower function that's involved here, and possibly some external load signal that's...

Welcome to the industry! And welcome to control.com. Any plant should have its own written operating procedures for the plant so that all personnel operate the plant in the same way. And those procedures define how the equipment in that plant is to be operated safely and efficiently. The...

What has the packager said you need to to do perform an off-line water wash? Or does their procedure presume the unit is cool to start with? This sounds reasonable to me; it seems you've taken the steam turbine into consideration by enabling the steam seals and bringing up vacuum and making...

In reply to M. Griffin, Whenever there is any kind of fuel or starting or Inlet Guide Vane (IGV) problem on a GE-design heavy duty gas turbine, real or perceived, one of the first things that most sites do is "calibrate" the LVDT feedback. To one of your points, "calibration" can cover up a...

There's precious little difference between a motor and a generator, which what you're asking about, I think. The major differences are that a generator converts torque into amperes, and a motor converts amps into torque. Amps are considered to flow "out" of a generator, and amps are considered...

I was being facetious. A Mark IV+ is an Intel 80286-based Mark IV (the original Mark IVs had i8086-based processors). What you are describing is the Mark IV-to-Mark VIe Migration, also known as the Mark IV Migration, or Mark IV M, or Mk4M. It is sometimes mistakenly called the Mark IVe...

You can run your generator any way you like, or any way you are required to run it by the grid operator of the grid you are synchronized to, as long as you keep the operation of the generator within the limits defined by the generator reactive capability curve. The generator reactive...

I'm not very familiar with steam turbine Mark V applications, but it would seem from your posts that something is causing TPWR to increase or decrease when the unit is starting or stopped. So, you should look at your CSP and find out all the things than can cause TPWR to increase or decrease...

In reply to Bob Johnston, The accuracy of LVDT calibration using AutoCalibrate is dependent on how well the actual measured positions are calculated using the Control Specification values and then those calculations must be entered into ACALIB.DAT. So, if an SRV is supposed to be at 100%...

Great question for Woodward Governor Co.! They are usually very helpful. You may even find a local office in your country you could contact for support; they have offices in many countries around the world. Get the Part Numbers and Serial Numbers from the valves (not the actuators!) and...

When did this problem start? After the servo was replaced? After some card was replaced? After some maintenance outage? We don't know what kind of control system is being used on the machine. Is the control SIMPLEX or TMR? If the control system is a Speedtronic Mark IV, Mark V, Mark VI or...

Good to hear you've located a source for the problem. If the seals are not maintained close to the shaft all around the shaft, then the amount of oil required to maintain the seal will increase, which will increase the amount of air liberated from the oil in the seal drain enlargement tank...

Lina T., Is this problem you are experiencing something that has developed over time or has it been ongoing since commissioning? How high is your L.O. header temperature? It would seem that you have some kind of water-to-air heat exchanger that you have tried spraying water on. Is this...
