I would add that www.wikipedia.org and www.howstuffworks.com and canteach.candu.org are all fine places for some very basic information about prime movers and controls. If you are working at a power plant or an industrial plant, you might find one of the more mature engineers probably has...

I'm concerned that you might think that when you are opening a CSP segment with the Master Sequence Editor (CSP Editor) that you are opening the segment which resides in the Mark V turbine control panel. You are not. You are opening the segment on the <I> which you are working at. And, when...

It's very difficult for me to understand how ambient temperature could affect the amount of air which is accumulating in the cooling water piping. You haven't indicated if there are throttling valves at the cooling coils for the flame detectors and if they have been properly adjusted. You...

Whether or not the <I>s are on the same StageLink or different StageLinks makes no difference at all. IDOS was written for specific BIOSes, and different BIOSes use RAM in different ways. And, as was said before, when a segment is "too large" the CSP Editor, also known as the Master Sequence...

Further to the clarification issue, the generator rating is a "static" number, usually given at a typical operating temperature and usually given at a rating so that one generator can be compared to another, such as 0.85, or 0.8. But that doesn't mean the generator can't be operated at other...

We don't really know enough about the alternator at your site. Is it a synchronous machine or an induction machine? If it's a synchronous machine, how is the DC field produced? Electrical power generation is about "relative motion" between conductors and magnetic fields. This is a question...

Use your preferred Internet search engine and search for 'generator capability curve' and/or 'generator reactive capability curve'. As for why it's "always" 0.8; it's not. It depends on how the purchaser orders the generator and how it's built. (Why are some bicycles more suited for mountain...

There are so many bells and alarms going off with this post, but, the originator has indicated he would provide information, so, let's see just how much he's willing to participate in understanding and possibly solving the issue(s). I need to start off by saying that while low-BTU gas fuel...

That's probably a very good decision. I still question the P2 pressure calibration, but I don't believe that's the entire problem. Certainly, missing turbine buckets could account for the problem being described here.

You say the same segment can be edited on another <I>. Are the two <I>s using the same CPU (Central Processing Unit) with the same amount of RAM? Sometimes, when a segment is very large (nebulous term, but this is Mark V) it can't be opened when IDOS is running, and sometimes when older <I>s...

There are several vendors with "specialized" turbine controls. Most, like Siemens, are PLC-based with some special components that make them more applicable to turbine control applications. Siemens does seem to have a more "unified" approach than some. As I recall when I had a brief look at an...

jojo, I have done some shipboard generator control work and troubleshooting, and the "islands" don't get much smaller than that. (Though some naval vessels are bigger than some countries I've worked in!) And, in all cases, even when dockside and loading and unloading with large shipboard...

Trust me on this: If a program could be written to perform DLN tuning, it would have been written. DLN tuning is part fuzzy logic, part fixed process, part intuition, part seat-of-the-pants, part anticipation, part mechanical engineer, part instrumentation and control technician, part...

If there is a leak in the atomizing air pre-cooler then CPD, which is at a higher pressure than the cooling water system will leak into the cooling water system (when the unit is running) and it will find it's way to high points in the system and collect there, until it is vented. Same for...

Try this link: http://www.avtron.com/pdf/wp-NGR.pdf As for why only one NGR was used for multiple generators, only the system designer can likely answer that with any degree if certainty. Different systems have different requirements, along with economic constraints and physical space...

When did this problem start? Was the motor running without this problem for some time and then it started? Did it start after some maintenance or cleaning was performed on the motor? How long has this motor been in service? When was the last time the motor was "serviced"? A 1000kw...

jojo, Frankly, I didn't really know how to respond to Muhammad Salman's post, but made an effort anyway. His summary asked about decreasing speed with increasing speed, and his post talked about decreasing speed with increasing load, and increasing load by increasing speed. Would you agree...

Every synchronous generator is provided with a chart or graph commonly referred to as a reactive capability curve, or generator capability curve. It's actually three curves that define the limits of operation of the generator. For a quick look at a reactive capability curve see the following...

Air will collect in high spots of piping if not periodically vented. The cooling water jackets of most turbine support legs have 'vents' which can be opened to relieve most of the air which will accumulate in the jackets. As for flame detectors, well, most of the installations were not...
