Makarem, Thanks for the kind words. People who know me are having a big laugh right now. I have little patience most of the time. Perhaps because I am near retirement I seem to have a little more. But a read of my reply to another current thread will prove I really haven’t (become any more...

ControlEng999, Sometimes it is the simplest things. At one site the remote operator interface module would experience frequent loss of communications—but only during the summer months and randomly as well. The cable was twin-axial (a bit unusual) but it meggared perfectly fine every time and...

Un_gineer, Let's try this tack. You seem to be saying there's a value on the DCS which comes into the DCS from a 4-20 mA transmitter, you'd like to see that value on the HMI for the Mark VIe/VIeS. IF the Mark* and the DCS share data using MODBUS or GSM or some other protocol/method it might...

Dontknowman, There are GE-design Frame 5 heavy duty gas turbines. And there are GE-design Frame 5 heavy duty gas turbines. Some are single shaft; some are two-shaft. Most ALL HP shafts are rated at 5100 RPM (5094 to be exact, but that's another whole entire thread unto itself). BUT not all...

luissz, Don’t ever apologize for offering your help and experience. EVER. We value it and are grateful for your contributions. I was referring to a command line utility, but my mind (stuck in glorious Mark IV land!!!) is not working properly today.

A shortcut to asking/telling about GT manufacturers could be using the terms “GE” & “SOB” (Some Other Brand). :giggle: What say the group?

ME42, Would it be possible to use one of the "direct" TCP/TP tools (I cannot remember the name of the one GE uses) to check the value directly in the I/O Pack? But, I think the original poster is unclear with his need and is over-simplifying the situation--at least that's my read of the...

Makarem, The minimum operating IGV angle for many GE-design heavy gas turbines is 57 DGA and that is to protect the axial compressor from damage. Unless the unit has DLN-I combustors AND IBH (Inlet Bleed Heat) and IBH is active while the unit is at Part Load (less than Base Load) then the...

Bagi, The Mark* does not control anything to do with the Cooling & Sealing Air system which is what controls the air flow to the bearings which is probably the source of the higher-than-normal pressure in the L.O. tank/reservoir, and it's likely that some orifices in the various lines were not...

Ejector, eh...? My experience with GE-design heavy duty gas turbines began in the days before negative-pressure mist eliminators. Back then a large diameter (6 inches or so) was run to the top of the exhaust stack and the vapours from the L.O. tank/reservoir were just allowed to enter the...

behrad_m, GE, from time to time, and as the design of the machine permits, makes changes to different components to improve performance (which means they can increase the price of the machine). Those changes are mostly as follows, though not all components are always changed at the same time...

Ali Sadikin, The second paragraph of the first reply (after the link to the thread with the instructions for resetting the alarm messages on the LCS/SLCC display) lists the most common causes of these alarms, especially if the numbers of the alarms are increasing with each scan of the display...

ControlEng999, "... at this resource i think there are some people who faced with such problems definetly. " I yield to others who--of course--have definetly faced with such problems as this. The GEH-6721, Vol. II, that I found on the World Wide Web doesn't have any section on PPRA. PPRF...

Welcome back, ControlEng999, Of course you have looked at the Mark VIe System Guide, GEH 6721, in the PPRA section, to see what the various Diagnostic Alarms mean and what troubleshooting steps are recommended (since that's the way to begin to understand Diagnostic Alarm messages which are...

Science20, I neglected to add that Toolbox/ToolboxST can be used to generate a report of all Process Alarms which are configured in the application code of the Mark VI. I don't have access to a .m6b file at this writing, but I believe if you open the project file for a particular turbine with...

The documents you request are only supplied with SOME GE Mark* digital turbine control systems (such as a Mark VI). In other words, they may or may not exist for your turbine and auxiliaries--and for the application code (program) running in the Mark VI. Some of the Mark* digital turbine...

Science20, What control system does the turbine have? What compressor control system is used?

I’ve been to a couple of sites that are using low-sulfur distillate fuel after using regular distillate (#2 diesel) for decades. They were operating fine and they weren’t using any additives at the time. They don’t operate often, and even less often on liquid fuel. This would be a great...

Pre-Selected Load Control is NOT a good way to operate GE-design heavy duty gas turbines. If the unit is being operated at Base Load (the BASE LOAD target/button on the "main" Start-up Display is usually orange to signify BASE LOAD is active), all the operator need do is start clicking on the...

LQ1, Who provided the panels? Did GE provide them, and were they drop-shipped to site from the manufacturer? Or, did the A/E for the power plant provide the exhaust equipment? GE is not as well-known as it should be for cost reduction moves. It's possible their sourcing people picked a new...
