We have suggested a method for controlling the AC transmission by an intermediate DC link, which is based on current converters with turn-off semiconductor valves. We have investigated normal modes of operation and shown the possibility of DC link (power transmission) work performed according to the suggested method in the modes with reactive power generation into the AC system. References 4, figures 3.
Key words: flexible transmission system, current converter, DC link.
