Problem 1: A = 250kV high-voltage de transmission system connects to a 230kV (line-line RMS voltage), 60Hz, three-phase ac system. Complete the following (25 points]: 7 - a) Assuming a delay angle of 18°, draw the three phase current waveforms for the rated dc current Ide = 1kA. [10 points). b) With a constant-input ac voltage and a constant de current, plot the locus in the P-Q plane as the delay angle is varied. [10 points). Repeat this when Idc is half of the rated value. [5 points). a
