HVDC Hokkaido-Honshu

From Wikipedia, the free encyclopedia

The HVDC Hokkaidō-Honshū or Hokkaidō-Honshū HVDC Link , Kitahon HVDC Link (ja: 北海道・本州間電力連系設備, abbrev. 北本電力連系設備) is a 193 kilometers long high voltage direct current transmission line for the interconnection of the power grids of Hokkaidō (Hakodate static inverter station in Nanae) and Honshū (Kamikita static inverter station in Tohoku, Aomori Prefecture), Japan. The project went into service in 1979 by Electric Power Development Company (J-POWER). A 149 kilometer long overhead line and a 44 kilometer long submarine cable connects the terminals. The HVDC Hokkaidō Honshū is a monopolar HVDC line with an operating voltage of 250 kV and rated power of 300 megawatts. This HVDC system uses thyristor static inverters.
