摘　　要：对XDJ1-550/35消弧线圈接入后某局35 kV配电网的运行数据进行了测量。根据XDJ1-550/35消弧线圈的参数及测量数据,计算了中性点位移电压百分比、三相电压最大不平衡度和脱谐度。对计算结果进行了分析,发现XDJ1-550/35消弧线圈存在档位选择困难以及容量不足的问题。利用ATP-EMTP软件仿真了该局现役的ACHC自动跟踪补偿装置的工作过程。仿真结果显示ACHC自动跟踪补偿装置的接入降低了电弧重燃的概率以及系统的弧光接地过电压水平,起到了较好的保护作用。Operation data of a 35 kV distribution network were measured after XDJ1-550/35 arc-suppression coil was connected to power system. According to the parameters of the arc-suppression coil and the measurement, the percentage of displacement voltage of neutral point, the maximum unbalance degree of three-phase voltage, and the out-of-resonance degree were calculated. The analysis of the calculation results reveals the problems of difficult gear selection and insufficient capacity of the arc＇suppression coil. The working process of an ACHC automatic tracking compensation device was simulated with the software ATP-EMTP, and the results show that the ACHC automatic tracking compensation device reduces the ＇probability of arc reignition and the overvohage level due to arc grounding, resulting in better protection to power system.
