<b>If</b> there is no automatic governor on the prime mover driving the synchronous generator providing some kind of speed/load control for the prime mover and the generator rotor, <b>and if</b> there is no automatic control of the generator terminal voltage, <b>and if</b> the generator and...

This appears to be an excellent example of mechanical problems being attributed to the control system. Maybe. I don't believe we have all the information, <b>however</b> if the HP turbine blades aren't all there, that's definitely a problem. The HP turbine can't reach rated speed, extracting...

To clear up some acronyms, GCI appears to be a typographical error, missing the "carats" for the product of Global Controls (www.global-controls.com): <GCI>. It does use CIMPLICITY as the main graphical interface, similar to the GE Mark V HMI. I don't know if <GCI> requires TCI or CIMBRIDGE (see...

Turbine efficiency is not just a function of filter type, size, media, configuration. It's a function of both filtration and axial compressor cleanliness, and filters can only remove certain types of contaminants (primarily particulates). Increasing the length would increase the filter...

Many F-class turbine installations have a gas fuel compressor. If the pressure output of the gas fuel compressor is variable, then you might be able to reduce the gas fuel pressure as you reduce load to try to keep the SRV above the sticking point. Once you get down to the point where the...

In addition to otised's fine advice, if you have no spread on gas fuel (or relatively low spread) and you have a high spread on liquid fuel it is likely easily found. Since the spread is only present during liq fuel operation, you can likely rule out any problem with combustion liners...

You still haven't told us what speed the HP shaft is at when it is experiencing 18 bar P2 pressure, which is clearly in excess of the 0.0133 psi/rpm (which would produce approx. 148 psi at 11140 RPM). There MUST be a way to measure the P2 pressure reference (a voltage) and compare it to the...

specifically, what do you want to do with the Laserjet printer? Do you want to print alarms? Or screen/image captures? Or print CSP?

This is an interesting re-start of a thread from more than 6 years ago. I thought I had read that GE and Fanuc had "split the sheets" and they have. http://www.automationworld.com/news-5878 I understood the agreement to disagree meant that GE kept the software and Fanuc took the...

I like to always refer to the reactive capability curve provided with a synchronous generator. This curve represents the limits of operation of a particular generator, and in my estimation, is useful in describing how the energy input to the generator can be "split" or divided. As we all...

"In the beginning..." there was only seismic vibration sensors. And, also, in the beginning GE gas turbines and GE steam turbines were produced by two different divisions of GE, though the engineering and philosophies of the gas turbine division were originally derived from those of the steam...

A P2 pressure of 18 bar seems excessive. The P2 pressure reference is directly proportional to HP speed, and you should be able to find the relationship in the 'Control Specification - System Settings' document provided with the Mark II, and necessary for any calibration procedure. You listed...

sud, The clarity you seek can be found in the term 'isochronous control.' There should be no droop control on an isolated system. If you are reading texts and manuals, skepticism is a good thing, unfortunately. A lot of these things seem to be produced by people who don't have any...

There's too much that could go wrong to try to list all the possibilities. I don't understand your explanation, at all. You say the GSM worked well, but yet you say that only four or six thermocouples operated properly. That doesn't seem to make much sense. To me, anyway. The Trip History...

Yeah; I've seen this before when critical data is sent to the BOP from the HMI. So, when the HMI can't get data for some reason, the BOP doesn't get any data, and if it then shuts off fuel the unit will "shut down". Did someone recently try changing something in the CIMPLICITY program or the...

ESKAY, If the alarm indicating a problem with the <Y> speed pick-up was annunciated (TCE1 HP reading,Hardware trouble for "S"{1680}) that means there was a problem with the speed feedback. That problem may be intermittent and that's why when you look at it now it doesn't appear to be a...

Thanks for the feedback! There should be a button on the LCC/SLCC keypad called 'NORM' (for NORMal) or something like that. Try pressing that button to return to the normal display.

My apologies if any of my posts were harsh; it was not my intent to offend anyone. My cynicism has been in overdrive recently. Any similarity to the attributes, faults, failings or disposition of any individual is purely coincidental, and unintentional. Did you have something positive or...

>>Have you tried resetting the System Errors on the <C> core using the LCC Display keypad? (Press the LCC key in the upper left-most corner of the keypad; the display should indicate "--i86 MONITOR--". Press the INC button at the bottom of the display keypad three times until the display shows...

Excellent post. Just a couple of questions, please. What would be remedy for electrostatic pitting? Most of these gear boxes do not have drive belts connected to them; the Main Hydraulic Pump and the High-pressure Liquid Fuel Pump and the Atomizing Air Compressor are all directly connected to...
