Hi everyone,

In my study, I am going to carry out simulation in IEEE39 system with integration of three DFIG wind farms, but every time I initialize my case the printer output many INITIAL CONDITIONS SUSPECTs :

I have tried many times of modifying the parameters of excitation, DFIGs and generators, but that not really worked.

Actually, if I just integrate one or two DFIGs, the initial conditions are ok. But I don't know what goes wrong when I integrate the three or more.

My raw and dyr files are attached on https://drive.google.com/file/d/1S8aawbNKoH7fSPdjN6Qu5IMQR2_ad0Ch/view?usp=sharing

Thank you in advance, any help will be appreciated
