Present status of research and development and technical bottlenecks of resistive superconducting fault current limiter

我国短路电流超标问题日益严重,对新型限流技术的需求迫切。电阻型超导限流器因其结构简单、自动触发、限流效果明显、技术上相对容易实现等独特的优势,在高电压等级的输电网具有广阔的应用前景,成为目前国内外新型限流技术研究的热点。主要介绍了电阻型超导限流器的发展背景、基本原理及国内外研究现状,并总结了电阻型限流器所面临的技术瓶颈与难题。

In China, the problem of short - circuit current level exceeding the standard has been more and more serious, so new type of limiting current technology is in demand urgently. Resistive type superconducting fault current limiter （RSFCL） has great application prospects in the high voltage transmission network and become a hot research at home and abroad, because of its unique advantages such as simple structure, automatically triggering feature, obvious current limiting effect and relatively easy to be realized in technology, etc. This paper mainly introduced the development background, basic operation principle and current research situation of the resistance type superconducting fault current limiter, and summarized the technical bottlenecks and orob-lems.
