对高温超导限流器(HTSFCL)的国内外发展及研究现状进行了评述.高温超导限流器作为一种理想的故障限流器,它的研制涉及物理、材料学、电力电子、低温工程等多领域学科的知识与技术,是一项多学科技术的综合.目前在世界范围内有18个国家参与了高温超导限流器的研制,已完成挂网试运行和正在运行的高温超导限流器有19台,分布在7个国家.在中国现有3台处于试运行中,其中1台运行于世界上第一个超导变电站——甘肃白银超导变电站内.世界各国的研究现状显示,高温超导限流器的技术趋于成熟,然而大规模的商业化应用还面临着几个制约因素:超导线材的高昂价格,维持低温运行的成本,技术标准的制定,市场对高品质电力的需求等.只有降低超导材料的成本和高温超导限流器的运营成本,才会出现超导限流器的大规模应用,使之成为保障电力网络稳定安全运行的一个理想选择.

The progress and development of high-Tc superconducting fault current limiter (HTSFCL) in the world have 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 19 HTSFCLs have been installed in different substations in the world,which had been operated or has been operating in seven countries at present.In China,three HTSFCLs 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 on SFCL in different countries,it is concluded that the HTSFCL technologies have been improved,but large scale commercial application is still facing several challenges,such as high price of superconducting wires,the operation cost of mnaintaining low temperature,building product standardization and the market demand for high-quality electric power,etc.If the superconducting materials price and the HTSFCL operating cost are 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 SFCL in the future.
