Aleem ALI, You really didn't tell exactly how your turbine is being operated. Is it operating in Simple Cycle mode, exhausting to atmosphere (possibly through a bypass stack if there's an HRSG (Heat Recovery Steam Generator)? Or is exhausting into an HRSG to make steam for a steam turbine...

Sanjay, There are hundreds of threads on Control.com about issues on gas turbines and with gas turbine operations. And many of them have some very good descriptions of issues and also of solutions. Some have very little descriptive information, and even when several possible causes and...

laxmi associates, Maybe on your contracts.but not on most contracts That's the problem with questions like this--we don't, and will likely never, know the details of the contracts.

PungentReindeerKing is correct. The WORST mistake most people make--especially with GE-design heavy duty gas turbines--is to operate in a mode that's always trying to maintain a load setpoint, and adjusting the turbine speed reference in doing so. In GE-speak it's called Pre-Selected Load...

PFC is a dangerous term to use these days when referring to proportional, Droop Speed Control, I am presuming your usage to mean proportional Droop Speed Control. Not Pre-Selected Load Control. Not PFR (Primary Frequency Response). Basic proportional Droop Speed Control. (Proportional meaning...

(Continued) NOW, what should happen in this case is that the grid regulators should notice the decrease in frequency and they likely have the ability to directly send a signal to one or more power plants not operating at rated power to increase their power output to return the grid to rated...

mariselvan, Please be extremely careful--and critical--of on-line documents (and textbooks and reference books) discussing droop speed control and various off-frequency operations. MOST of the time they do not state all of the conditions for their examples. MOST of the time they are presuming...

Ngassaki, Methinks you are possibly confusing fire detectors with flame detectors.?.?.? In GE-speak, a fire detector is a device that senses intense heat (which would be indicative of a fire) where there should be none, such as in the Accessory Compartment, the Load Compartment, and even the...

Ngassaki, The LG1093AA26 is a flame detector--which is used to detect the presence of diffusion flame in a combustor (such as when the turbine is burning fuel in a diffusion flame). Combustors are located only in the turbine compartment of GE-design heavy duty gas turbines. I suggest you...

Merabiko8, This alarm condition is not usually a shutdown or a trip, but, some packagers of GE-design heavy duty gas turbines do sometimes use it to initiate a shutdown, or a trip as well as a start-check permissive. Without being able to the configuration and programming running in the Mark*...

Very little information was provided, and most times when an alarm is described as an "anxiety" it's because it's preventing a START. So, in the absence of any other information, the most common reason for an anxiety-causing alarm was used as one explanation. But, still, no information about...

RTFM. Read The Fine Manual. Because you haven't told what the fire detection system is, we can't be of much help. Usually, GE uses a fire detection/protection system, or a F&G (Fire & Gas detection/protection system) which is independent of the Mark* (which you didn't tell about, either). This...

morefus1, I think it would be most noticeable in the electrical power output. As both the air flow and fuel flow-rate increase the electrical power output would be higher than for the same ambient and machine conditions when the IGVs were actually at 86 DGA and the unit was operating on exhaust...

morfeus81, Increasing the IGV angle while on exhaust temperature control will result in more air flowing through the machine. The effect of that increased air flow is to allow the turbine control system to admit more fuel--which causes the firing temperature (NOT the exhaust temperature) to...

Crasucks, Use your preferred World Wide Web search engine, and you will probably find what you are looking for in papers written by Masters' and Ph.D students (thesis papers). Woodward Governor Company has a lot of "white papers" (theory and principle) they publish about load sharing and...

mariselvan, I do not know of another thread on Control.com for other OEM's turbine control systems. I can say that Droop Speed Control is what allows generators and their prime movers made by ANY manufacturer to all be synchronized together. That means, that whatever the notations and...

chitourh01, What turbine control system does the turbine have? If the turbine control system is a GE Mark*, can you tell us what Diagnostic Alarms are present that are related to the IGV servo output and LVDT feedback? (It might just be easier to send a screen shot of the Diagnostic Alarm...

Impossible.

If you were asking about job openings in the USA you should look at job postings on sites such as LinkedIn, indeed.com, monster.com, careerbuilder.com and many others. If you're asking about opportunities for non-USA residents, that's an entirely different topic, and one that's likely to see...

Don Clark, I re-read your reply and if the spare UCSA also came up with a DRAM error upon power-up I would definitely also be looking at the power supply output voltage to the processor. Remove the power supply connector and after powering up the power supply check the voltage at the...
