I've implemented DPC for DFIG in matlab/simulink. In that, active power (Pref=0.9pu) be well controlled but the reactive power (Qref=0) instead of remain at zero, it is fixed at -1?!!
Please let me know your suggestions ?
Best Regards
can you give more explanations for your question. I think that the generator's reactive power does not follow its setpoint (reference). If it is the case contact me buck to give you some explanation. if not give me please more explanation.
best regards.
Hello, dear Messini
I also think that the generator's reactive power does not follow its reference.
More explanation about my simulation:
For my simulation I've used the detail model of Matlab's demo, and my implemented DPC should controls the rotor side converter(RSC).
In my DPC : The system works in D_Q reference frame(Stationary reference frame on the rotor).
sector is the position of the rotor flux(sai_r_DQ), dP={-1,0,1} and dQ={-1,1}
For dP it is assumed that: if deltaP>0.04; dP=1; elseif -0.04pu
Dear Aria,
I don't see the whole model so i have to know how you represent your power flow.
If the power is positive when it flows from the machine to the network, or the inverse. so you must define the direction of flow for me. and if it flow from the machine to the network the active power must be positive and the reactive power is negative (since the IM always consumes the reactive power even if it works as a generator. please give me the whole model explanation or contact me by mail.
best regards

Dear Aria,
I think studying the following manuscripts and analyzing their MATLAB codes can be helpful for your research.

Dear Messini,
I have the same problem with Mr. Younesi when I implement DPC for the rotor side converter of DFIG in Matlab. I have used the same algorithm as Mr Younesi.

Please let me knows my problem

Hello, dear Messini
i have the same problem with Ms.Younesi and Mr .Binh Quang
there is no change of the actual power (active and reactive power) compared with the references......
Please let me knows my problem
all the best
