A Study on Capacity and Voltage Class to supply HTS Power Transmission Cable to Metropolitan Area

고온초전도 케이블의 대도시 계통 적용을 위한 송전용량과 전압계급의 검토

It becomes difficult and high in cost to construct new ducts and/or tunnels for power cable in Metropolitan area. This paper presents the possible application of a HTS superconducting power cable for transmitting electric power in metropolitan areas, reflecting its important distinction such as compactness for installation in underground ducts and considerably economical efficiency comparable to present underground cables. In this paper, review of transmission capacity and voltage class of compact HTS cable which should be applied to existing ducts was performed.
