| 摘 要： | 由于零序阻抗的影响,110 kV同杆双回输电线路采用常规线路保护配置时,当一回线路发生接地故障,另一回线路的保护会产生相继动作的情况,对该保护的动作行为进行了分析,并提出了改进措施。

| Abstract: | When adopting the conventional scheme of relay protection configuration for 110 kV double-circuit transmission lines on same tower,if a ground fault occurs on one line,the protection of the other line will act later,due to the influence of zero-sequence impedance.The line protection tripping behavior is analyzed and the improvement measures are proposed. |
