Phil Corso, You keep saying there's no such thing as reactive power, but you acknowledge that VArs are required for the ind-gen to work, and that they must come from the grid. So, VArs are 'consumed' and 'produced', just like watts. And, you're not the first person to accuse me of not...

This happens when new bearings are installed in the machine. Cooldown, sometimes called "slowroll," through the Voith torque converter is VERY dependent on oil temperature. It must be above approximately 27 deg C (approx. 80 deg F) to maintain slowroll. It is also dependent on bearing...

Phil Corso, I was counting the number of exclamation points until I choked on this tidbit: >The "grid" to which it is connected >must be able to supply the Ind-Gen's >magnetic kVAr! <bSupply</b> VArs!?!?!?!?!!!!!???!!??!?! That means VArs must be produced!!!!!!!!!!!! HAH...

Have you searched control.com for any information about water injection? Try this post, and then write back with any further questions (questions--not doubts!): http://www.control.com/thread/1258022399

Ramanath, From my somewhat limited experience with F-class machines, the use of heated fuels is not that common but is becoming more common. The installations I have worked on or visited with heated fuel (usually only a single gas fuel, natural gas), there has not been a need for independent...

Do you believe everything you hear? GE has used the Mark VI as DCS, and is continuing and even expanding that usage with the Mark VIe. The Mark VIe has a smaller "footprint" for many applications and so lends itself to easier implementation in distributed applications (meaning that some of...

Sometimes different divisions of the same company have competing products. And this is one of those situations. The OC6000 and OC6000e were never designed as turbine control systems, more as "enhanced" PLCs to be used as DCSs (Distributed Control Systems). The hardware is very different, in...

Iqbal, I have one very important question to begin with: Did you ever have any indication of flame intensity with the previous turbine control systems used on the turbines? Or, was it simply a logic signal indicating the presence or the absence of flame, not a logic signal derived from flame...

ali, This is a very broad question. It would help if you could narrow the question by telling us what industry you are working in. You say "...the book contain a lot of them including unnecessary instruments...." Which "book" are you referring to? In my experience, I have found catalogs...

Susan, I may be dating myself here, but a reference to a 501F GT means a Westinghouse-design heavy duty gas turbine. Now, Westinghouse doesn't make gas turbines any longer, and I'm not even sure who owns that technology now, but a 501F is not a GE-design heavy duty gas turbine. Please...

GE makes a distinct difference between <b>turbine tripping</b> and generator breaker opening (sometimes called breaker tripping). A turbine trip (which is the title of this thread) means an immediate shut-off of fuel, followed by a breaker opening. As you have described the situation, the...

sardar9, Sometimes, just a simple Internet search using your preferred Internet search engine will yield quicker results than a search of control.com. This was the first result on a Google search for 'Anhydrous versus Hydrous Ammonia': http://www.wahlco.com/ammonia-systems.php

The first topic you requested has been covered many times before on control.com. There is a 'Search' field at the far right of the menu bar at the top of every control.com page. (It's strongly suggested to use the Search Help to understand the syntax of search terms.) As for your second...

prakash, The module you are referring to was, for a while, an option. People could purchase the ability to monitor the dynamic pressure pulsations (acoustic monitoring) for a fee. I believe that some of GE's turbine packagers, and even GE's remote monitoring & diagnostic center(s) now...

It's 13 June 2011, and this thread was originally posted on 11 May 2011. The originator has never responded to any questions or with any additional information. Any further questions of the original poster, or any speculation on this thread, is probably not a good use of anyone's time since...

Technically, the Mark VI is no longer currently in production, though some of GE's companies seem to still be shipping turbines with Mark VI control systems probably using the last of their store of Mark VI components. The digital control system known as the Mark VI Speedtronic (though I'm...

pichet, Thanks for the feedback!

If Base Load is enabled and active, then you shouldn't be able to increase load at all. So, the real question, because you have the answer<b>--you just want it to be something other than what it is</b>--is how are you increasing load when Base Load is enabled and active? The answer you...

VR-21 and -22 are <b>NOT</b> to be used to set the Hydraulic system pressure. They are <b>relief</b> valves to protect the hydraulic system against overpressure. If they are used to set the system pressure the flow through the respective hydraulic pump will be excessive and is a cause of...

Iqbal, Your post is a little confusing. You say you have two machines, but you don't say if the flame detector problem affects only one unit or both units. Further, you didn't tell us what fuel the unit is running on when it has the flame detector mismatch. <b>Most importantly</b>, you...
