| 摘 要： | 本文介绍了单相基本桥型高温超导限流器的基本工作原理,及其参数变化对限流特性的影响.在此基础上研究应用于电力系统中的改进桥路型高温超导故障限流器实验室样机,正常工作情况,在电桥上引入直流偏置电流,不出现限流现象;短路故障情况,整流桥中的直流偏流影响限流效果,在桥路上引入限流电阻,使故障电流限制到预定的范围.研究了该限流器的工作原理,分析限流参数的变化对其限流特性的影响.实验表明,该限流器有很好的限流和重合闸能力,能显著减少暂态及稳态的故障电流。

| Abstract: | In this paper,the basic theory of the single phase rectifier type high temperature superconducting fault current limiters is introduced and the effect of parameters variety of HTSCFCL is analyzed on limiting fault current.A improved rectifier type high temperature superconducting fault current limiter is developed.When normal operating,no current limiting mode occurs through the application of DC bias current to the bridge,and at the time of fault,the fault current limiting capability decrease due to the bi... |
