Abstract

High-temperature superconducting (HTS) power cable has significant merits of compactness and large power transmission capacity. To evaluate its performance, safety and reliability, HTS cable system was constructed at Tokyo Electric Power Company's Asahi substation in Yokohama, and the HTS cable had been connected to a real grid from October 29, 2012 to December 25, 2013 for the first time in Japan. The in-grid operation had continued for more than one year without any accidental interruption of the operation or troubles of the system. It is concluded that the HTS cable system has good performance and stability for long term in-grid operation. This paper describes the result of the HTS cable demonstration and their characteristics.
