Describe the effect of resistive load on sending and receiving end voltages, Power transferred and Power factor.
A bipolar HVDC link is delivering 1000 MW at ±400 kV at the receiving end. Calculate the losses in
the line, assuming the resistance per conductor as 1 2.
Also estimate the sending end power, sending end voltage, power in the middle of the line, and line
losses.
