Hi Raj, I have downloded your DVR.mdl file. I try to apply it on my system and it dosen't restore the sag voltage. My system is 3-phase 400V source, 500KVA load. I think that the problem is in choosing the parameters of injection seriese transformers. Could you help me choosing the full parameters of injection seriese transformers, or the proper way to apply the DVR model on my system, please?
Regards
