故障限流装置的发展和应用

The Development and Application of Fault Current Limiting Device

在综合大量文献的基础上综述了国内外各种故障限流装置的研究现状、发展应用,特别对广泛应用的电力电子类故障限流器 FCL(Fault Current Limiter)和前景广阔的超导类故障限流器 SFCL(Superconducting Fault Current Limiter)进行了比较深入的分析,对各类限流装置的技术水平做了比较,提出了实用化过程中存在的应用问题,并对限流装置的发展趋势做出了预测。

With the rapid increase of power system capacity, more and more fault current limiting devices are using for meeting electrical power demands nowadays. In this paper the research situation and applications of fault current limiting devices are discussed and summarized. Considering developing trends, we put our emphases on the power electronics fault current limiter(FCL)and the superconducting FCL. The characteristics and technological levels of various kinds of fault current limiting devices are analysed, including their advantage and shortcomings of every sort of FCL. Finally,some application problems in practice are put forward.
