I'd have to dig through some of my documentation (and it's a lot of stuff not really organized), but I seem to remember that LM6000's where primarily controlled by compressor discharge temp (T3 they call it if I remember correctly). Also, LM6000 is a twin shaft unit and the HP section changes...

Glad we could help you out. Another industry standard book that is very in depth and specific on boilers is "Steam, Its generation and use" by Babcock and Wilcox. However, it only discusses boilers (design, construction, compromises, etc).

I think the original poster would benefit from doing a plant heat balance for the intended system. If you have your steam flow and conditions, you can theoretically calculate how much power you will get from a steam turbine. The depth that you are trying to dive into this project is not...

Constant pressure keeps the same working pressure in the boiler and controls power output by using control valves on the turbine and adjusting firing rate. Sliding pressure essentially keeps the control valves on the steam turbine wide open and adjusts output with pressure/firing rate. I...

Much more data is needed AND an experienced vibration professional is needed to help you pinpoint your problem. You may have enough equipment on site to gather the data, but you need the proper type of data and details. Then this needs to be presented to somebody that can interpret the data...

That story of going to a major vendor (perhaps an OEM????) sounds very familiar for many components. In my experience it appears that independent repair shops that specialize in repair/overhaul of components are usually able to provided excellent value by keeping a usable component in service...

This thread is amazingly stereotypical "enginerd" talk (and I mean that as a joke, not insult). As an analogy: if we take a nice flat and smooth piece of metal, I can say, "that is a nice smooth surface on that solid object". But if you bring out a microscope and look at the surface, you...

GE Package Power (Aeroderivs) mostly uses Woodward Micronet. GE Energy Speedtronic works so "great" on heavy duty stuff mostly because of convention and tradition. I agree, Speedtronic control system is designed for running GE "heavy duty" gas turbines. But if you talk to people who work on...

I will piggy back CSA's post to help illustrate a point. Hopefully my ASCII diagram is correct and understandable. Power Factor (PF) never goes above 1.0, but it changes from lagging to leading. This can be confusing in words so look at the diagram below. The voltage examples are just...

>Can anybody give me an explanation for >giving DC supply only to alternator >field? I'm not an electrical whiz, so I try to keep it simple. DC current is used in the field (rotor) to make an electromagnet instead of using a permanent magnet. The desire is to have a rotating magnetic...

why would somebody need a megwatt reserve function when any unit (GE or not) could be run in speed (aka droop) mode?

You need to give more information. What type of controller? Has the unit ever been stable? Is this unit synching to a grid or sharing load with other units or is it a stand-alone unit? If synching to some type of grid, how is it "speed hunting"? Does your controller have online...

JPE, In the past I've registered with the GE portal you list but it didn't get me anywhere useful. GE seemed so concerned about protecting information that many hoops and verifications were needed to gain access. I'm sure the community appreciates you reaching out, but unless GE...

The P-core settings are physically changed by moving the jumpers on the P-core card. The IO configurator has a screen where you input the desired over speed trip point and then it tells what position to put the jumpers in. After changing the settings in the IO configurator you must do an...

My memory may be off a little bit, but on the MkV steam turbine I worked with there were multiple overspeed protections. I want to say one is controlled via the sequencing (usually with a constant) and is called primary overspeed trip (set at 110% usually). The next protection is called...

In the first post, you stated: T - Receives 96SR-1 (4A) & 96SR-2 (4B) outputs (HIGH SELECT) [through the terminals noted above] I'm just tossing out simple ideas (sometime it's the simple thing that is the problem)...but if I read correctly, it appears that <T> may agree with <S> for a...

View2T is pretty self explanatory in the documentation. I understand that. I was looking more for information regarding setting up a logic point to trigger the view2t. Regardless, I got some input from the GE TA that visited our site. He said I will probably have to add a comparator in the...

or your generator could be blown up...yup I've seen it. "couldn't excite the unit" The stud on the rotor that connects the field windings broke and bounced around and also shorted out stator bars.
