Research and development of superconducting cable in Super-ACE project

摘要

Research and development of fundamental technologies for superconducting AC power equipments (called Super-ACE) project started as a national project in 2000 fiscal year by Ministry of Economy, Trade and Industry and New Energy and Industrial Technology Development Organization. This project is to research and develop the basic technology of high temperature superconducting cable (HTS cable), fault current limiter, and transformer. Main subjects of the cable in this project are to study the 3 kA superconducting cable conductor, cooling technology of 500 m HTS cable, and power system analysis of cable and AC equipments. The present 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.
