briq, If I recall correctly it was possible with some version of IDOS and/or TCI to compile the Table files with a Scale Set other than English. If you check the Help for the Table Compiler at a command prompt by typing: TABLE_C /? and pressing ENTER, if that is possible it will be a...

grajesh, Thank you for the kind words. As for Mark VIe training, well, to the best of my knowledge about the only company that can provide that is GE. You might contact www.hpcnet.com, or www.gasturbinecontrols.com (the latter is an advertiser here on control.com). To give training on...

> how do you increase the reactive output of a synchronous steam turbine generator? The same way you increase the reactive output of any synchronous generator: By varying the excitation. If the excitation is equal to the amount required to make the generator terminal voltage equal to the...

Bronx9669, The below presumes you are working on a new plant.... You didn't say exactly what kind of work is being done with the Mark VIe (new unit installation; retrofit/upgrade). What you need to know--and this can be mostly gleaned from the Mark VIe System Guide, GEK-6721, is about...

Phil Corso, Very good! You're getting the hang of this. When an electric machine is not being driven by a prime mover and it's connected to a grid--it's a motor. And, when it's being driven by a prime mover and the torque being provided by the prime mover exceeds that required to maintain...

Has100, The suffix "A" on the signal names is for analog feedback of the output current--which I've never seen used on any application. The following is from an IO.ASG I have from an old job:<pre> Q_R_MAO01 ASROUT PCT ; TCQA_PREF_1 POSITION REF [ASROUT] Q_R_MAO02 Q_R_MAO02...

has100, There are several versions of GEH-6195, with varying numbers of pages. The information you seek is shown on the Signal Flow Diagram page for the TCQB Milliamp outputs--it looks exactly like the TCQA milliamp outputs, but different terminals on a different terminal board (the TBQD...

Hi, Phil Corso, From POOM's second post to this thread: > 1. GAS TURBINE TRIP, excitation off BUT Gen. breaker not > open. What will happen to turbine & generator? Phil, what would you call a synchronous generator operating without excitation and no prime mover while still connected...

POOM, There is an error in my previous post in the following sentence in the response to Question 3: > Synchronous motor becomes induction generator--BAD for > generator. No damage to turbine. It should read: Synchronous <b>generator</b> becomes induction generator--BAD for...

Bronx9669, ToolboxST requires a GE-provided UPD--a USB Protective Device--to install or to open any site-specific project (site-specific files are called projects). So, you would need to obtain a CD/DVD with the application and supporting files, and a UPD to be able to install it on a PC, and...

POOM, > 1. GAS TURBINE TRIP, excitation off BUT Gen. breaker not > open. What will happen to turbine & generator? The synchronous generator becomes an induction motor--NOT GOOD for the generator. No damage to the turbine. > 2.GAS TURBINE TRIP, excitation on BUT Gen. breaker not open...

Wajid29, Thank you for the progress update. By the way, the last sentence of my second reply should have read: "I would <b>NOT</b> recommend checking valve positions with the unit running...." If one opens the bleed valve too fast while the block valve is open, hydraulic pressure will...

POOM, Hmmm.... The Subject of this thread is: "Generator Breaker Cannot Open" and the Summary refers to the generator breaker--which is presumed to be the three-phase, high-voltage circuit breaker that connects the generator output to a grid/load. And yet your two questions below refer to...

JJss, Thanks for the kindly feedback. It might be clear, but the presumption is that T/Cs connected to the TBQA on <R> will be "redundant"--that is, that when a parameter is being measured (like Fuel Temperature-Gas (FTG)) there will be three T/Cs in the piping measuring the temperature of...

grajesh, I may not be the best person to comment on this, but in my opinion they are not that different from a technical perspective. By that I mean that they both require a good deal of "digging" and reading and familiarization--they are both difficult from a technical perspective. Yes...

John Look, Hmmm.... Doesn't sound logical does it? It would seem if there was a requirement for Minimum Load to be 18 MW, that would mean that during starting and loading the load would have to increase at a pretty fast rate to get to and maintain 18 MW. Breaker closure usually occurs...

Jerryy/MIKEVI, What about enabling the SOE change-of-state on the three switches--it logs to the Alarm Window changes of state of discrete (contact) inputs with a 1 ms degree of accuracy. Or is the already enabled for these three switches?

Wajid29, Also, what is the Hydraulic System pressure doing during the instability? Is it stable, or fluctuating? Does it seem like the Hydraulic Accumulator is working correctly? How long since the charge on the Hydraulic Accumulator was checked? Are the valves on the Hydraulic...

Wajid29, What Process- and Diagnostic Alarms are being annunciated during starting? Please be as concise as possible with your list of alarms (both Process- and Diagnostic). Use Toolbox to check the Diagnostic Alarms of the cards which have the orange Status LED lit on the card edge. When...

Sardar99, Things have really changed at your site, haven't they? From your post it seems the unit was tripped (L4 @ "0") and yet it was still running.... When did this occur? After a maintenance outage when the "gas valves" were calibrated? Which fuel was the unit running on when it...
