Question

Figure B2 shows an HVDC system connecting the 400 kV electricity
networks of two countries (System A and System B) through a 400 km
submarine link, capable of transferring up to 600 MW. Each cable has
a dc voltage rating of 300 kV, and a resistance of 0.01 Ω/km.
(i) The primaries of the transformers at each end of the link are
connected to the 400 kV ac network. Calculate the highest
value for the transformer secondary line voltages.
(ii) Is it the best option to select this highest value for the
transformer secondary line voltage, and why?
