Answer Question
Bipolar HVDC Transmission System
Hello Sir,
I am woking on 'Distance Protection for HVDC transmission Lines'. For dat i am using CIGRE HVDC benchmark system. It is modified to bipolar.
Here i am attaching my model. for normal condition without any fault its not giving voltage and current magnitude as 1pu.. rather i am getting very less magnitude less than 0.5 pu.
Sir can u please rectify my problem and tell me my mistakes.
