摘　　要：近年来,随着电网的扩大,特别是电缆出线的增多,使得系统总的电容电流增加较快,包括线路、母线及其他一次设备的对地电容电流。当系统的某一相发生接地故障时,对地电容电流会相当大,接地电弧不能自动熄灭,越来越多的瞬间单相接地故障不能自动消除。为了解决这一问题,目前普遍采用中性点经消弧线圈接地的补偿方式。接地后可有效地减小流过故障点的电容电流,减小了弧光接地过电压的概率及有利于电弧熄灭。该文主要对自动跟踪补偿消弧线圈测控单元进行研究与分析。in recent years, with the expansion of power grid, especially increasing of the cable, which makes the system capacitive current total increase rapidly, including lines, bus and other primary equipment to ground capacitance current. When one phase of the system occurs ground fault, the ground capacitive and current is quite large, ground arc can not automatically extinguish, more and more instantaneous single-phase ground fault can not automatically eliminate. in order to solve this problem, the current widespread use of the neutral point through compensation arc suppression coil grounding. Grounding can effectively decrease the capacitor current through the fault point, reduce the arc grounding overvoltage and is beneficial to arc extinction probability. This paper mainly focuses on the automatic tracking compensation arc suppression coil control unit to carry out research and analysis.
