Shin Shinano
Shin Shinano (新信濃変電所 Shin Shinano Hendensho) is the designation of a back-to-back high-voltage direct current (HVDC) facility in Japan and the location of the Shin Shinano Frequency Converter Station.
Shin Shinano is located at 36°8′14″N 137°52′58″E / 36.13722°N 137.88278°ECoordinates: 36°8′14″N 137°52′58″E / 36.13722°N 137.88278°E

[edit] HVDC plant
The HVDC back-to-back facility Shin Shinano uses line-commutated thyristor converters and went into service in 1977. The station houses two converters, one of which opened in 1977, the other in 1992. The original 1977 converter used oil-insulated, oil-cooled outdoor thyristor valves supplied by Hitachi and Toshiba. The 1992 converter uses more conventional air-insulated, water-cooled thyristor valves using Light-Triggered Thyristors. In 2008 the original converter was decommissioned and replaced by a third converter, similar in design to the 1992 converter.
The Shin-Shinano link operates with a dc link voltage of 125 kV for each converter. The station was initially rated 300 megawatts. In 1992, with the addition of the second converter, the maximum transferable power was uprated to 600 megawatts.
[edit] Frequency Converter Station
The Shin Shinano Frequency Converter Station is one of three frequency converter stations that link Japan's western and eastern power grids. The other two stations are at Higashi-Shimizu and Sakuma Dam.
