High temperature superconducting transmission cables the future of power transmission in north america

摘要

Today, in the area of underground transmission cables the need for new installation or replacement of the existing ones with larger capacity cables is greater and greater for various reasons. Development of high temperature superconducting (HTS) transmission cable systems provides an opportunity to bring the transmission systems towards an advnaced generation with largely increased capacity. This paper describes the design concept of a room temperature dielectric HTS cable and summarizes its development progrma. The advantages and applications of HTS cables ar ealso discussed. Taking into account that HTS cable systems will be competitive with conventional ones it is foreseen that a large portion of North American utilities will adopt the new generation of cables in the near future.
