Abstract

Super-conducting AC power equipment project started as a national project in 2000 fiscal year by METI and NEDO. This project is to research and develop the basic technology of super-conductive cable (high temperature super-conductive cable, HTS-cable), fault current limiter (FCL) and transformer. Main subjects are to study the 3 kA Super-conducive conductor, cooling technology of 500 m HTS-cable, manufacturing technology of 66 kV/1 kA class SN type of FCL, high voltage technology of AC magnet and pulse magnet, and power system analysis of super-conductive cable and AC equipments. The paper describes the background of this project, target of each research subject, schedule of research and development, and major results of research activity in 2001.
