rokan_123, The plot thickens even more.... That unit has some very unique features I have NEVER seen before. You are going to have to work with the supplier of the unit (GE; BHEL) to understand what is going on. I suspect that more than one feature is enabled when only one should be, OR...

demigrog2, I'm not being specific enough again; sorry! It's an occupational hazard, made easy by GE's well thought out decision to use Mark VIe after Mark VI. The subject of this thread was (allegedly) about Mark VI, but the description mentions Mark VIe. Personally, I have a need to work...

demigrog2, I have one more, semi-rhetorical question, please. Why does the File Save icon in Toolbox or ToolboxST go red when you create a Trend, and why when you save the Trend does the equality change to Minor Difference? Is there a way around this? It just FREAKS people out--and a...

rokan_123, >(Actually I am not expecting steady load but what I am >expecting is an amount of Load that is consistent in the >same frequency level i.e. if load is 98MW at 50.0HZ >frequency for one time so whenever 50.0HZ frequency appear >the unit would be 98MW(that's my expectation)!!)...

RJ_VR, I'm very disappointed to hear about your doubts. But, your question isn't really related to this thread. Whether the unit is in FGMO or Pre-Selected Load Control it is in Droop Speed Control. Pre-Selected Load Control is an outer control loop to Droop Speed Control. If the unit...

demigrog2, Thanks for the information. The "stand-alone" version I'm talking about was one that could be used to look at Trend Recorder files without having Toolbox or WorkstationST running. (I believe it was developed primarily because the M&D Center needed to be able to look at Trend...

demigrog2, Thanks for all your great responses! I forgot that in some versions of Trend Recorder you had to left-click on the diamond at the top of the cursor lines to drag it.... And, while I rarely use the statistical analysis feature of Trend Recorder, it's great to know they're there and...

>In the trend has a reading Left value and right value. What >its meaning please explain? There are two "cursors" which extend vertically from the top of the window to the bottom of the trend window (or, I guess from the bottom of the trend window to the top). One is on the right side of the...

Esoteric_Stone, Pre-Selected Load Control is just a very bad way to continuously operate a GE-design heavy duty gas turbine (unless the unit has the GE Primary Frequency Response Option and it is also enabled)--a very bad way. AND, if the grid frequency is unstable it's even a WORSE way to...

IconPhaby, This topic (failure to accelerate to FSNL because of high exhaust temperature) has been covered many times before on control.com. (There is a 'Search' field at the far right corner of the Menu bar of every desktop control.com webpage. The search syntax is not like most World Wide...

rokan_123, I don't understand how you can keep saying that you want to get the unit to hold a steady load at 50.0 Hz, when you now say the grid frequency won't be at 50.0 Hz for even one minute. 99 MW is pretty close to 117.9 MW, and if the units are exhausting into HRSGs (boilers) then...

rokan_123, You say your unit has 10% Droop, and is rated at 117.9 MW. That means that for every 1% change in TNR (Turbine Speed Reference) the load will change by 11.79 MW when the frequency of the grid the unit is synchronized to is 50.0 Hz. (90 MW/117.9 MW) = 76.33% of rated MW. Because...

I have never seen ACCUM.DEF, but I would like to. I’™m not exactly sure what you’re asking (though I have a suspicion as to why you’re asking), but accumulator values are stored in EEPROM, a non-volatile memory area (meaning that the values stored in this kind of memory are...

rokan_123, I may not be the nicest person to explain this, and I may not have done it in the nicest manner. And, when I say "you" and "your" below I am referring to ALL the people who want THEIR power plant to remain stable during times of grid frequency disturbances--not just you...

If your Mark IV was commissioned in 1990, it was one of the newer Mark IV panels, and it may have been supplied with some user-configurable parameters. And, even if it wasn't, I believe it was possible to change the USER ID. So, even if you believe the password hasn't changed, it's very possible...

IconPhaby, Actually, there's a LOT of information that's required. Type of Mark V: SIMPLEX or TMR Was the Mark V powered down and then powered-up just before all these alarms became red? Is there more than one HMI, and if so, is the same thing happening on all HMIs? Do the...

SP, Many liquid fueled units have one or more filters in the liquid fuel system--both the supply (low pressure) and the high pressure (after the high pressure liquid fuel pump). Many liquid fuel systems also have a strainer on the suction of the pump(s) that provide the liquid fuel to the...

Hello, apm, The power factor of a system (the sum of all the motors and lights and computers and computer monitors and televisions and tea kettles) is what it is. It's not possible to "control" the power factor by changing "a" generator setting. I think what you'll see is that when you try...

sid100, The I/O Configurator is used for configuring the software regulators of servo-valve outputs (gains; offsets; biases; regulator type; etc.). The software regulator doesn't care what the milliamp range of the servo coil connected to an output is. HOWEVER, the TCQC card DOES care what...

arun, There is a really good World Wide Web Forum particularly suited for this type of question: https://www.generatortechnicalforum.org/ Membership is free, and you have a LOT of forum and sub-forum choices to choose from when posting questions. In my experience, most slip ring...
