ESKAY, I'm not going to go into the issues with transferring fuels; they have been covered ad nauseum in many threads on control.com. There is a lot of information that was not supplied that would be required to say for certain exactly what happened, but there is some information below...

Okay, so it looks like the Booster AA Compressor motor is only drawing about half of rated current so that tells us it's not working very hard which tells us the Booster AA Compressor isn't working very hard. Now if that's because you have put a blind downstream of the compressor is not...

Namatimangan08, It is irresponsible to suggest changing droop settings (droop characteristics) and <b>then</b> checking to see if it's legal or permitted by the grid regulator. Changing droop settings (droop characteristics) is not to be done lightly, and the cavalier manner in which you are...

A Main AA Compressor Inlet temperature setpoint of 107 deg C (225 deg F) is still above boiling, which would prevent condensation. I would suggest the water you are seeing in the piping is condensation, not necessarily from water washing. (The only reason water washing was suggested was because...

Just a word of caution. Changing the droop characteristic can have many unintended knock-on effects, including instability and sanctions from grid regulators. Droop is not something to be messed with lightly or if you don't understand all of the ramifications and consequences. Please...

Everyone has their preferences, and in the absence of any documentation from GE everyone can do whatever they please--and they do. I was just curious; that's all. I noted that you didn't include forcing 20TV-1 and didn't mention the "manual command" screen. Is that a User Defined (Demand)...

This is a perfect example of people operating machines and equipment without a clue as to what normal operating conditions are. Just push the button or click on the target, while sitting down, and sit and wait to push the next button or click on the next target. Oh, and acknowledge those pesky...

Your I/M dept is correct; <R> processor decided that the turbine should have been tripped. The best way to determine what caused that would have been to use the Auxiliary Display to view the Process Alarm drop numbers in <R> to find the condition that caused <R> to want to trip the turbine...

> 1. when plant islanding we will re-Synch to grid 5 minutes That's a relatively short period to drop load to less than 50% while trying to use Preselect Load to maintain frequency, <b>and</b> maintain steam production. > 2. HRSG (NEM)capacity 140 t/h and duct burner I presume that's...

I really shouldn't be allowed to proof-read my own writing. There's a mistake in the sentence paragraph below; it was originally written: ><b>You</b> choose to use (insist on >using, rather) a formula with values >that relate RPM and P2 pressure, with >values 0.08 <b>PSI/RPM</b> and -25...

Oh, the plot thickens. (Well, a few minor, important details were left out--like just about all the most important details. But, that's par for the course these days, it seems. Unfortunately.) No worries about the language; we're understanding what you're telling us, when you provide the...

sardar9, From a previous post you said that the Mark IV Control Constants FPKGNG and FPKGNO were 2.88 <b>PSI/%</b> and -25.4 <b>PSI</b>. If the data from the first column of your most recent post is converted to % TNH, and the data from the third column are used, then FPKGNG are FPKGNO are...

I always find it interesting that no one questions how current is converted to torque in a motor, but they have great difficulty in understanding how torque is converted to current in a generator. I always love to ask the question: Why do we generate electricity? The responses range from "the...

In order for there to be combustion the mixture of air and fuel has to be within certain limits. Generally, in GE-design heavy duty gas turbine DLN combustors operating in premix mode the amount of air is very, very high in relation to the amount of fuel. You can think of it like the hydrogen...

pascal, I have a couple of questions. First, I would ask why you aren't using AutoCalibrate. AutoCalibrate will do this "extrapolation" for you. (There won't be any maths errors when AutoCalibrate is used.) Second, why didn't you explain how to measure the IGV angles at the minimum- and...

Okay; I've made a pretty big mistake here, getting my island load and export numbers mixed up. The three paragraphs listed here should have read as below: >If the load suddenly drops from 80 MW >to 36 MW, the Isoch machine has to cut >it's power output very sharply from 38 >MW to 2 MW, and...

The facts are that the <C> mA outputs are driven by <Q> via F:\UNIT1\MAOUT_Q.SRC. The fact is that the I/O Report, file F:\UNIT1\TC2KREPT.TXT, lists the output terminals on the CTBA card for the output which was assigned the signal in MAOUT_Q.SRC. The fact is that the Mark V Application...

<b>When did this problem start?</b> How old is this machine? The more likely cause for the problem is that the backup exhaust temperature control curve Control Constants are causing an intersection with the primary exhaust temperature control curve.
