Somewhat off topic, but, it's not so much inductive losses (inductors are lossless afterall) but the improvement in system stability from using a DC link. A 1000 km power line is a transmission line, and changes in power flow "ring" back and forth for hours. Traditionally, this was done with variable capacitors and inductors at the link ends to shift the phase, but with modern thyristor stacks, you can either synthesize it at the end (a short "DC link") or use DC for the whole link. The latter has some other useful benefits, as well.
