hany5757, As for familiarizing oneself with the Historian (<H>), have a look around on the <H> hard drive for some .pdf files about how to use it. Personally, I have worked very hard at avoiding them since my first experience with them, and even more so after my fourth and fifth...

hany5757, <b>ANY</b> threaded cover is going to eventually get corroded and/or galled if some kind of thread lubricant isn't used when the covers are removed and replaced. For older covers which didn't have the thread lubricant applied, one has to carefully remove the covers, and using...

hany5757, On most newer GE HMIs there is a folder for 'Documentation' and in that folder they are putting a LOT of documents--GEHs and GEIs and I've seen some GETs, as well. Unfortunately, all of the document filenames are just the GEx-nnnn designation, so one has to open every one of the...

methzzz, When IGV Temp Control is enabled an active, it will keep the IGVs closed to try to maximize exhaust temperature (TTXM) without exceeding TTRX (Exhaust Temp Control Reference--which is ALSO the maximum allowable exhaust temperature for any given operation condition). CSRGV, the IGV...

Hi, If I remember correctly, CIMPLICITY is "linked" to a microprocessor when it is licensed. And, generally, most PCs have only a single microprocessor. I believe you need to call GE Intelligent Platforms in North America to get a new license number to be able to transfer the license from...

hany5757, You need to find GEH-6721, the Mark VIe System Guide, on the HMI and review that document (it's usually two volumes). It's a good place to start understanding. For the ETR and PTR business you need to go to Vol. II, and look at the PPRO section; you will find there is a TRPG card...

The grid will supply whatever is not supplied by the generator in the configuration you describe. Your generator needs to operate in Droop speed control mode--because it will be paralleled with the grid, and as such you will need synchronization circuits and protection, as well as other...

rajkumarkrishna, Have you consulted the L.O. P&ID to see if there are any orifices in the line to the T&T valve? Perhaps the L.O. Bearing Header Pressure Regulator failed, causing the L.O. bearing header pressure and flow to be less than required, but the pump discharge pressure was okay...

Is the generator connected to the Customer's MAIN bus? Or is the generator connected separately to the grid, and the Customer's MAIN bus is also connected separately to the grid?

dontknowman, The subject of suddenly high wheelspace temperature readings after a maintenance outage has been covered many, many times on control.com. Use the search term: "improper insertion" as one of your search criteria (WITH the double quotes), and you should find many threads...

MAz, Good information, and good questions! Do the compartment vent fans draw their air from after the turbine inlet air filters? How old are the vent fans? Could they be worn and/or dirty and not flowing as much air as in the past? Even if you're moving the same or slightly less air, if...

Amr1589, Another victim of the OEM Sales group.... This particular OEM, when selling gas turbine control upgrades, believes they are both entitled, and required (by safety regulations and standards--many their own), to provide every turbine they retrofit with the same control and protection...

suryapower, What about the water washing question? How many starts since the last maintenance outage? What is the inlet filter differential? What is the exhaust duct back pressure? Are you using the DWATT transducer or counting watt hour meter revolutions/increments? How many...

SKS, Take any combination of watches--they can even be the same model from the same manufacturer, set them all to exactly the same time, and carry/wear them around for a few days and then compare the time shown on each watch. You don't even have to carry/wear them around--just leave them in...

Amr1589, Can't comment on the NEW control code without being able to see it. I suspect what the field service person meant to say was that a new algorithm was included to protect the axial compressor against surge/stall conditions which can occur under certain ambient conditions (which should...

Dear Sir, So, just to be clear--it seems your problem is not how to download, but the fact that you (mistakenly) believe that a download is required to solve the problem which you are attempting to solve. "Just downloading" to any Speedtronic turbine control panel as an attempt to solve a...

Amr1589, What are the Process Alarms being annunciated when this "problem" is occurring? What are the values of CSGV and CSRGV when this "problem" is occurring? Also, what are the values of TTRXP, TTRXS and TTXM when this problem is occurring? If the IGV reference, CSRGV, and the IGV...

macker, To add to what glenmorangie is asking--when did this problem start? It's presumed all was working fine for some time, until.?.?.? What changed? Is there some kind of PMS (Power Management System) for the generator-sets that controls the power of the droop units and lets the Isoch...

jhurt, Large DC solenoids can cause the Mark V to have problems; many generator breaker closing solenoids draw a pretty hefty amount of current and then exhibit a pretty large inductive kick when the circuit opens. GE worked around this issue by putting "snubbers" on many of those large...

Maythem, Thank you for the feedback!!! Thanks, also, to glenmorangie for his assistance and input!
