 the hvdc volgogradâdonbass is a  long bipolar Â±400&nbsp;kv high voltage direct current powerline used for transmitting electric power from volga hydroelectric station at volgograd in russia to donbass in eastern ukraine and vice versa.cory, b.j., adamson, c., ainsworth, j.d., freris, l.l., funke, b., harris, l.a., sykes, j.h.m., high voltage direct current converters and systems, macdonald & co. (publishers) ltd, 1965, p242. the volgogradâdonbass system was the second hvdc scheme built in the former soviet union, following the moscow&ndash;kashira hvdc scheme which has already been shut down. the volgogradâdonbass system can transfer a maximum power of 750&nbsp;mw. when completed in 1965,compendium of hvdc schemes, cigrÃ technical brochure no. 003, 1987, pp 24&ndash;27. its operating voltage of Â±400&nbsp;kv was the highest in the world, and remained so until the completion of the Â±450&nbsp;kv nelson river scheme in 1977. the scheme is today in a bad state and only operated with a voltage of 100&nbsp;kv. nevertheless, it is still being modernized, as a google map picture of its crossing with m-4 motorway at  shows, where one can see that new pylons for the crossing of the motorway are under construction. == volzhskaya converter station == the terminal at volga hydroelectric station, volzhskaya converter station, is situated on the dam of the power plant at . each of the poles consist of four series connected three-phase valve bridges, which form two series connected twelve pulse bridges. or
