摘要

超导故障限流器由于其理想的电性能，已成为电力系统中限流器的重要发展方向之一。本文综述了SFCL的主要电学行为，包括SFCL的工作电流与超导线圈(SC)的熄灭电流的关系，以及SFCL的等效基频阻抗与超导线圈的正常状态电阻的关系，并讨论了SFCL的工作损耗和响应时间。分析了猝灭型和非猝灭型SFCL对线路电流和节点测量阻抗波形和总谐波失真(THD)的不同影响。采用电磁仿真的方法分析了SFCL的特性。

Comparison of superconducting fault current limiter in power system

Due to its ideal electrical behavior, the superconducting fault current limiter (SFCL) has become one of the most important development trends of limiters in power systems. This paper summarizes the main electrical behaviors of SFCL, including the relationship between SFCL's working current and the quench current of the superconducting coil (SC), and the relationship between equivalent fundamental frequency impedance of SFCL and normal state resistance of SC. Operation losses and response time of SFCL are also discussed. The paper analyzes different influences of quench type SFCL and nonquench type SFCL on waveforms and total harmonic distortion (THD) of line current and node measurement impedance. Electromagnetic simulation is adopted to analyze the characteristics of the SFCL.
