I saw the currents going into the Aconis-2000 on sheet G35 but isn’t that the governor control? The AVR (Capture.PNG) appear to me to be a different stand alone device as I looked up the Hyundai 6GA2–491-1A . Or is there some interconnection that I am not seeing?
Thanks
To be perfectly honest, I'm confused as hell what with another similar thread here and PhilCorso's comments and the info from the original poster. I still think the problem is with either the AVR or some input(s) to the AVR. I haven't really understood if there's some kind of load control/power management system (one which would control frequency of the bus AND possibly reactive currents (I don't know if the AVRs have reactive current compensation or not).
I would really like to know if there was any work done to the equipment (governor; AVR; generator control panel; switchgear (with CTs and PTs). To my way of thinking if there are three governors all operating in Droop Speed Control mode (and with--presumably equal droop characteristics) then this doesn't look like a governor thing. Now, it could be a hydraulic problem (presuming the fuel rack is hydraulically operated--but I don't know enough about this diesel and how it's controlled to really say that, in all honesty).
Based on the information provided, it's very odd what's happening. Swapping controllers and AVRs is just strange. I haven't seen anything which tells me it's the diesel that's acting up, even though PhilCorso is alluding to it but won't provide details about why that's his hypothesis.
Anyway, this without actionable data I'm not going to venture any more ideas or suggestions. I just hope the original poster provides a believable explanation--because oftentimes when we get problems like this on Control.com some of the "explanations" are out there, as in from deep space, in a galaxy far, far away.
I'm backing out of commenting on this for a while. And, actionable data is what's really required here. (That and I gotta sort the issues between this and the other similar (in my mind's eye) thread that's currently being worked on Control.com.)
Apologies for any confusion I may have caused or contributed to.
A while back I was accused of being "very angry". That term is silly! But, I am disappointed that several men supposedly educated and/or trained in trouble-shooting Gen-set operation don't use the basic terms like, RMS VALUES, PHASORS, POWER properly.
Many have used the terms Volts, Amperes, kW, and Power-Factor. No-one, I repeat no-one has, expressed the term, "power-factor" correctly! It should be expressed in 3 words, Power Factor, "Lag or Lead". Those that have used it, "assume" it's lag!
I'm also disappointed that no-one, I repeat, no-one looked at the Diesel, to confirm or reject my theory of "underloading"! The point is that effects are VISABLE!
Well, in closing, I wish you all a successful, bright life!
Goodby, Phil Corso
Blake James...
It's been a while since you brought your paralleled Genset problem to this forum. Hopefully, you have solved it. If not I can still help!
I have produced an Excel program that simulates the situation, and can provide it to this Forum. If are interested contact me at [email protected]!
