摘要:

本文對高溫超導限流器(HSFCL)的國內外發展及研究現狀進行了評述。高溫超導限流器作為一種理想的故障限流器，它的研制涉及物理、材料學、電子工程、制冷技術等多領域學科的知識與技術，是一項多學科技術的綜合。目前在世界范圍內有18個國家參與了高溫超導限流器的研制，已完成掛網試運行和正在運行的高溫超導限流器有20臺，分布在6個國家。在中國現有3臺處于試運行中，其中一臺運行于世界上第一個超導變電站-甘肅白銀超導變電站內。從各國的研究投入和競爭現狀分析顯示，高溫超導限流器的技術趨于成熟，然而大規模的商業化應用還面臨著幾個制約因素：超導線材的高昂價格，維持低溫運行的成本，市場是否對高品質電力的需求等。如果降低超導材料的成本和高溫超導限流器的運營成本，就會出現超導限流器的大規模應用，使之成為保障電力網絡穩定安全運行的一個理想選擇。

Abstract:

The progress and development of high-Tc superconducting fault current limiter (HSFCL) in the world has been reviewed. As an ideal fault current limiter, the development of high temperature superconducting fault current limiter has been a multidisciplinary technology, which related to physics, material science, electronic engineering and cryogenic technology. The study and fabrication of HTSFCL have been improved in 18 countries, and 21 types of HTSFCL have been installed in different substations in the world, which had been operated or has been operating in six countries at present. In China, three types of HTSFCL are operating in Yunnan, Tianjin and Baiyin. One of them is installed in the first superconducting substation in the world – Baiyin Superconducting Substation in Gansu province. Analyzing to the research works, investment and competition on SFCL in different countries, it is concluded that the HTSFCL technologies have been improved mature, but large scale commercial application is still facing several factors, such as high price of superconducting wires, the operation cost of maintaining low temperature and the market demand for high-quality electric power, etc,. If the superconducting materials price and the HTSFCL operating cost is reduced, the large-scale application of the superconducting fault current limiter will be realized, so as to protect the power grid operating stably and to make HTSFCL as an ideal limiter in the future.
