摘　　要：本文针对实际运行中存在的串补旁路对测距算法影响提出解决措施。对串补装置的各种旁路情况进行了分析,针对不同旁路情况,利用串补未被旁路或旁路后的双端测距公式对相应的时段进行滑窗测距,提出了考虑串补旁路情况的串补线路双端测距方法。工程案例验证表明,本文的测距方法行之有效,且具有较高的测距精度。Most of the researches on the two-terminal location of series compensated lines are based on the theoretical models of MOV,and there is no research considering the bypass conditions of series compensation.In this paper,various bypass conditions of series compensation are analyzed.According to different bypass conditions,the two-terminal location formulas without bypass or after bypass of series compensation are carried out for corresponding time periods by using sliding window method,and a twoterminal location of series compensation line considering the bypass conditions of series compensation is proposed.The engineering case shows that the location method is effective and is of high accuracy.
