Major milestones in the development of high voltage direct current (HVDC) technologies and concepts were achieved in 1950s. Thanks to the high power thyristor switches (1960-70s), the HVDC technologies reached a significant degree of maturity in 1980s. The classical HVDC uses thyristor-based current-sourced line-commutated converter (LCC)

The ultra-high voltage direct current (UHVDC) system is widely applied in long-distance transmission lines because of its advantages of large capacity, low power loss, and good economy [1-4]. Generally, since the power generation of an energy base is very large, it is necessary to transmit the power to multiple load centre [ 5 ].

An HVDC transmission line has lower losses than AC lines for the same power capacity. The losses in the converter stations have of course to be added, but above a certain break-even distance, the total HVDC transmission losses become lower than the AC losses. HVDC cables also have lower losses than AC cables.
