High-voltage direct current (HVDC) transmission systems are widely used in many projects all over the world. In Japan, several HVDC systems are in operation, and a new system, the Kii-Channel HVDC, was put into operation in June, 2000. The HVDC is a bulk transmission system and its transmission capacity is to be built up to 2,800 MW. Hitachi supplied the main equipment for this system, such as thyristor valves, converter transformers, and control & protection panels. These products are based on state-of-the-art technologies described below.
