DC Power Transmission
For the elementary dc transmission line represented in Fig. 4-24a, the ac voltage to each
of the bridges is 230 kV rms line to line. The total line resistance is 10 , and the inductance
is large enough to consider the dc current to be ripple-free. The objective is to transmit
100 MW to ac system 2 from ac system 1 over the dc line. Design a set of operating
parameters to accomplish this objective. Determine the required current-carrying capacity
of the dc line, and compute the power loss in the line
