Thank Marmite for your input. So, this means I could get a negative bill if I produce energy more than my demand and export the excess to my utility? I would be grateful if you could explain more your sentence "only to frantically backpedal when the money ran out"
Thanks and regards,

Hi All,
This may sounds a basic question, but I would appreciate any feedback.
With distributed generation becoming more viable (especially solar systems on the roof of customers' buildings), customers might produce energy more than their demand. In this case can they sell it to electric...
Thank you very much guys, your contribution was absolutely helpful.
I finally figured out the missed joint in your discussion. The way I should set the machine to operate on the droop mode is based on the difference between a reference power and the actual power. This difference should be...
Once again, thanks guys.
Davidbeach, No, it is not a school project, it is a real project. This is a remote area hybrid power system project. Part of the project is to implement duel fuel engines. Our engines should work on diesel/hydrogen. We are modeling the engines from scratch and we want...
Thank you very much Guys. Your information was absolutely invaluable.
I think I need to make my query more clear to get most of your help. As I said in my first thread, my question was rather a simulation issue.
Currently I'm in a designing stage, so I'm trying simulate the dynamic...
Thanks Catserveng,
I have checked these documents but I still feel there's something missing!
My confusion is about the frequency/load curve, (or droop curve?). To run the generator on the droop mode, after removing the "i" gain from the PI controller, is it just changing the reference point...
Many thanks Davidbeach and Bill, I appreciate your contribution.
Just to make sure I understand what you mean, let me explain what I understood:
Both governors are using PI before and after the connection. So, if the PI is in the form:
PI= kp*e + (ki/s)*e
where kp and ki are the gains, s is...
Hello Everyone,
This is rather a simulation question, but it needs a practical point of view.
We have two Diesel Engines. One is working normally and the other is just a stand-by. Both engines are the same ratings (35kW). We need to test the power sharing if they are operating in parallel...
Thanks Guys for the invaluable feedback.
What happened is when I restarted the engine again, for some reason, the voltage stabilized on 430V. However, when I overloaded it, the voltage dropped to 160V, and started to fluctuate again even when I disconnected the load, the voltage did not reach...
Thank you very guys for your quick prompt.
the set size is 30kW, and it does not have a voltage regulator.
If the governor is not working properly, the speed won't be constant, would it?
Could the exciter cause this problem? It is supplied with a constant dc, though!
any further comments...
Hello All,
This is my first post for me in this wonderful forum.
I have a diesel engine set. I started it with no load. The speed of the rotor was constant, 1500 rpm. However, the output voltage was fluctuating from 160 to 220 volt. Is there any reason for this high fluctuations?
Thanks in...
