Doesn't sound like the local shop that did the refurbishment(s) is much help; hopefully, they haven't been fully paid yet for the work(s). I'm greatly becoming a huge fan of holding back 10% minimum, sometimes more, and not paying the money if the work is not satisfactory. How about getting...

Similar messages also occur when one tries to run MK5MAKE.BAT in the wrong directory. You must be in the unit-specific directory (i.e., F:\UNIT12for example from your original post) when executing the batch file. Is this a multi-unit HMI? It's been a very long time, but if the HMI is a...

This popped up during a related search: http://www.ashdenawards.org/ I haven't looked at it very closely, but it seems to have some interesting projects of all kinds.

Mark IV cards are no longer available from GE, but there are several sources, including one who supports this forum, Gas Turbine Controls (www.gasturbinecontrols.com). An HMI is the operator interface for a control system. GE no longer produces the Mark VI, and are currently selling Mark VIe...

Thanks for the feedback! It really is the most important contribution here at control.com. Again, it just goes to show how important it is that the files in the PROM subdirectory match the PROMset revisions that are installed in the Mark V turbine control panel. That was a good catch on...

In my opinion, in an emergency situation if you have to shut off the hydraulic pumps because of a massive leak, then you have to shut off the hydraulic pump. I would imagine it's not desirable for the bearings, but consider the condition where the plant loses AC and the unit comes down on the...

So, this isn't a new torque converter, it's rebuilt; it wasn't rebuilt by the OEM; and the problems started after this torque converter was installed after a hot gas path inspection, which shouldn't have affected the bearing conditions (presuming it was a typical hot gas path inspection). You...

otised, Depending on the age of this installation, the originator should have received written documentation of any problems GE has identified via TIL or PSB or ETC (including those with solder joint problems). Many Customers choose, for whatever reason, not to have GE come and fix the...

This is an excellent illustration of two very important aspects of maintenance & operation. The first is the need for regular rounds by operators looking for, among other things, oil leaks that can be spotted before they become a trip and potentially damaging to the unit. The second is the...

otised, If you have knowledge of some PSB or ETC or TIL related specifically to this problem, can you please provide the number(s)? The original poster did not provide much in the way of information. I have seen this problem occur when there are serious grounds on the 125 VDC supply, or...

Bruce, I have no aversion to maths; rather, I just think that in general it doesn't have much of a place in most of the discussions we have here on this forum which are more of a general theoretical nature. Perhaps we need more maths, but that remains to be seen. When I think of speed in...

sd, You're not the original poster, are you? You've just added your problem to this thread, haven't you? You say this is only happening on one unit at your site. You say you've increased the torque adjuster setting to "maximum". You say you can get the shaft to break away from zero speed...

First, what is prp (PRP)? Second, I don't see where you've tried directly connecting your current injection to the Mark V PTBA terminal board. Have you done that? Or only from the "prp" through the interconnecting wiring? Third, when you say you swapped A and C, did you do that by...

Bruce, You've used this description several times before, of a machine increasing speed when it's loaded while being operated in parallel with other machines on a grid. To me, at least, this is somewhat confusing. So, I would like to ask you if my understanding of your interpretation is...

This question has been covered many times before in many ways on control.com. Use the 'Search' feature to search for Pre-Select Load or Preselect Load or Droop Speed Control for more detailed descriptions (you'll find a lot of references). You have not provided us with enough information to...

See this thread for the most important consideration in making this decision: http://control.com/thread/1255317497 Security is paramount to any other factor. You could use any SCADA software if you're just looking for load information. If you're looking for more than that, you'll need...

Have you tried searching the hard drive for the missing file? It sounds like something is a little haywire in the Windows Registry or some configuration setting, or some virus has caused settings to change or files to be deleted or re-named. Is the anti-virus protection signature file in use...

If you have a GE-packaged and -provided machine, you will have a document called the Control Specification. That document will usually have some explanation of Temperature Matching. There may also be something in the GE-provided Instruction Manuals on Temperature Matching. Remember, when...

Unfortunately, I don't have any experience on any other manufacturer's machines, but I'm working on trying to remedy that. The issue with injecting any kind of diluent (water or steam) for emissions control directly into the combustor is that over-injecting can cause high dynamic pressure...

First, and most importantly, hopefully nobody was hurt. Second, as the owner/operator of a unit which is no longer under warranty, you are free to make any changes to the protective logic, or any other logic, that you see fit to take responsibility for. If you and your company as owners...
