We don't know if you have a Mark V or a Mark VI or a Mark VIe. But, if you need a step-by-step procedure for these processes, I suggest what you really need is training.

I am completely at a loss for the relation of a problem with IGV control to turbine compartment temperature. I have seen some turbine compartment ventilation fans that take their suction (inlet) from the filtered, and sometimes cooled, turbine (axial compressor) inlet air--upstream of the...

I don't know if the originator will get this email, but there are tens of threads on control.com with the exact calculation of exhaust temperature control <b>REFERENCE</b>--which is what TTRXB is, the reference, not the exhaust temperature. Using the 'Search' feature of control.com will yield...

If you have a GE Mark V HMI running MSWindows & CIMPLICITY then you should have a copy of GEH-6421 somewhere on the hard drive of the HMI. All you need to know next is that the the displays are made using a CIMPLICITY application called CIMEDIT and all the displays are files which end in...

Phil Corso, I really <b>don't</b> want to start any kind of exchange On the subject, but I believe that you are the <b>only</b> person I'm aware of that thinks that torque and amps are not related. My texts and references all relate torque and amps directly. The formula I remember from...

ProcessValue, The title of this thread indicates this is for a GE Mark V HMI, not for a Mark VI or Mark VIe HMI which most of your experience seems to be related to. There is a "folder" that appears in the Start | Programs list sometimes called 'Toolbox' of some GE Mark V HMIs. It includes...

Adam, I don't understand the need to control torque by some means other than the prime mover governor. I will be curious to see how you will control the emf which will be generated in the "open" windings, and how you will "close" them again. I will also be interested to know how much...

The GE manual for GE Mark V HMIs is GEH-6126. You may find the information you are looking for there. Unfortunately, GE's password protection schemes for most of MSWindows-based HMIs they provided is pretty poor, and documented even more poorly. Later versions of HMIs seem to be a little...

A start-up after a maintenance outage, or after a forced outage (emergency trip)? Some Diagnostic Alarms reset when the condition is resolved. Most require a Diagnostic Alarm RESET to be manually initiated. Some application code ties a MASTER RESET to the Diagnostic Alarm Reset, and some...

Have you RTFM (Read the Manual)? The Mark VI System Guide, GEH-6421, lists the Diagnostic Alarms for each of the VME-style cards in Vol. II. While the information may seem cryptic, it's all there is if one can't determine what the alarm message is trying to say from the context of the...

The 7F Users Group is probably one of the better users groups; it is (or at least it was; I haven't been to the site in about two years) very well used with some very knowledgeable users who are very quick to share their experiences and opinions. There are MANY 7F users (including FA, FA+ and...

I'm guessing you're looking for something free, and you should know that many companies are in the business of selling these simulations. They are not simple or easy to develop, and the problem is that many people buy inexpensive simulations and then want to use them for plant modeling and...

You would do well to review the documentation for the microcontroller you are considering connecting the speed pick-up to. If it's capable of using a passive, magnetic speed pick-up it will likely have programming and configuration information in the manual (or Help file) that is specific to the...

This problem seems to occur most frequently on turbines retrofitted with Mark VI and Mark VIe control systems. The sensitivity of the passive, magnetic speed pick-up inputs has been increased so much that they can be subject to erroneous, intermittent indications. There are essentially two...

Wow. You haven't provided any context for the alarms, nor if there are any Process- Alarms that were also annunciated at the time. Did this occur prior to an emergency trip? After some grid frequency excursion or driven compressor surge/stall event? Did they occur after replacing some card...

You should work with the packager/manufacturer of the gas turbine to analyze the hot gas path components and axial compressor configuration, first, to determine if this is feasible from a hardware standpoint. Second, they will also likely calculate a new CPR-biased exhaust temperature control...

Go ahead! Try On-line Washing at Base Load. Tell us what happens.

You might have mentioned it before, but it wasn't clear (at least to me). And, UFS is not a term I'm familiar with, and is one of the points of information that I maintain we aren't fully aware of and don't know enough about. Look, every installation of GE-design heavy duty gas turbines is...

<b>Note to our friendly, local moderator: "lbyrith" is likely text-speak for labyrinth, or labyrinthe.</b> Now to the original poster's query. People love to use acronyms and mnemonics all the time, many times in the wrong context. You are essentially correct in saying that foreign object...

RY, As has been said before, you are probably battling more than one issue here as liquid fuel systems are very complicated. From the data provided, it would appear the LFBV is going fully closed in an effort to try to get the actual flow-rate to be equal to the flow-rate reference...
