I just entered 'GEI-100517.pdf' (without the quotation marks) into my preferred World Wide Web search engine (which is NOT Google, by the way), and was taken to several links to be able to download GEI-100517.pdf. (I also don't typically use scribd, because they want to charge for the privilege...

Hello, GE used several methods to communicate via MODBUS over the product life of Mark VI. One used TCI and another used CIMPLICITY. The HMI communicates with the Mark VI using EGD (Ethernet Global Database), and any signal that is communicated to the DCS must first be available via...

I have never worked on a GE-design heavy duty gas turbine with ANY type of inlet air cooling that the operations department hadn't coerced the I&C (Instrumentation & Controls) to lower the minimum temperature. NEVER.

It is <b>very common practice</b> for generator set packagers to program the control system to annunciate an alarm for <b>ANY </b> condition that results in a trip of either the prime mover or the generator breaker. WHAT alarms are being annunciated when the breskers are tripping??? If there...

guyyi, It's not a linear degradation over time. There are a LOT of variables which can affect the degradation, some of which can be mitigated, such as with on-line and off-line compressor water washing and changing turbine inlet air filters. The packager of your GE-design Frame 6B heavy...

Nickey, I see you're a student; that's good. And you want to test a gas turbine; that's good, too. What is the purpose of your test? Are you testing the thrust developed by the turbine? Are you testing the efficiency of the turbine (fuel per unit thrust)? Are you testing the mass flow...

MetoMeto, If steam was still flowing into the turbine through the stop & control valves then what was happening was that the amount of torque being produced by the steam flow through the turbine was exactly equal to what was required to keep the generator spinning at synchronous speed, which...

bonera12, If the FSR went to 100% about the only thing that would cause that to happen without an Exhaust Temp High Alarm and -Trip would be a problem with the gas fuel supply pressure and/or flow-rate (I'm presuming the unit was running on gas fuel, but a problem with liquid fuel supply...

Chemsouhd, I did have one more thought after looking through GEH-6721, Vol. II (Rev. F). There have been reported problems with UCCC cards related to dead batteries on the cards. Have you tried replacing the battery on the UCCC, then re-installing the original CF card, and re-installing...

viniviru, We don't know anything about the governor used on the steam turbine at your site, or how it's configured during parallel operation or when islanded. There are generally two types of governor modes: Droop and Isochronous. Isochronous is usually used on a prime mover and generator...

Chemsouhd, >I took off the CF of the older Controller I inserted >it on a new one. it worked fine, without any setup of IP or >whatever (through downloading as well as boot routine, >software...etc). I'm pretty sure none of us understand the "problem" you are trying to describe. Do you...

joe45678, Hmmm.... That's interesting that swapping the U9 EEPROM chip is mentioned in any GE documentation. I'll have to try to obtain a copy of the GEI you mentioned. I suspect the problem you were experiencing was that you hadn't used the LCC/SLCC keypad to tell the new card (with the...

thsaji, At the risk of sounding like a broken record, it seems there is something atypical about the arrangement of the gas control valves and the gas fuel system on the unit(s) at your site. I have seen some GE-deisgn F-class heavy duty gas turbines that had the gas fuel module placed next...

RJSolo, First, thanks very much for the feedback! And most importantly, for the excellent detail about what you've done and what the results were. The LVDT feedbacks for the gas control valves are typically connected to the TBQC card on <R>, and then are "fanned out" to the three TCQA...

RJsolo, Actually I don't have any frustration with AutoCalibrate--it works just fine (usually!). It's just how people use it--and their unreasoned expectations--that cause my frustration. I suspect if the site hasn't been using the dielectric grease on ribbon cable connectors that could be...

If only ... we always received such detailed descriptions of precisely what troubleshooting was done AND what the results were. (And if wishes were nickels I'd be a very wealthy man.) But, alas, I digress. It's always been my understanding that the AuotCalibrate function was contained in...

Hmmm.... Several things come to mind, the first of which is: Are you using the proper LVDTs rated for the temperature of the environment? Typically, GE uses LVDTs which are rated for high temperature applications, and I have never seen or heard of splitter valves being placed in a turbine...

mohsin, - Motors convert amperes into torque. - Motors get their amperes from generators. - Generators convert torque into amperes. - Generators get their torque from the prime mover coupled to them (in your case, a reciprocating engine). - Prime movers produce torque from the...

As I wrote, I was working on very little sleep yesterday (it's that time of year again--outage season!). And something seemed a little off, and it still seems a little off. The last two alpha characters are throwing me off. Where did you get these part numbers? Are the last two characters...

>Is there a difference between these two type of cards: >DS200TCCAG1BAA and DS200TCCAG1AJB? The DS200TCCAG1BAA is newer than the DS200TCCAG1AJB (the G1Bxx is newer than the G1Axx) card. The last two alpha characters are production revision numbers which don't apply when considering whether...
