摘　　要：文章分析了串联补偿电容对高压输电线路故障暂态电流的影响以及串联补偿电容保护电路对单端暂态保护的影响,并对串联补偿电容装置位于线路首端的高压输电线路进行了仿真。仿真结果表明串联补偿电容对单端暂态保护的影响比较小。因而在考虑串联补偿情况下,单端暂态保护仍可正确区别故障线路和非故障线路。The influence of series-wound compensatory capaci- tance on transient current of high-voltage transmission lines is analyzed. The influence of the protective circuit of series-wound compensatory capacitance on the non-unit transient protection is discussed. The high -voltage transmission line with series-wound compensatory capacitance is simulated. The result of the simula- tion indicates that when series-wound compensatory capacitance is considered, the criterion of non-unit transient protection can also distinguish between the fault line and the non-fault line correctly.
