摘　　要：在高漏抗式消弧线圈的基础上提出一种识别系统接地状态的方法,研究接地故障消失后,高漏抗式消弧线圈在不同的晶闸管导通角度对系统电压的相应影响,利用跟踪电压的方式来判断接地故障状态,并分析了频率跟踪算法在接地故障诊断中的实际应用情况。This paper proposes a method to identify the system grounding state on the basis of the high leakage reactance arc suppression coil.After the ground fault disappears,the corresponding influence of the high leakage reactance arc suppression coil on the system voltage at different thyristor conduction angles is studied,and the ground fault state is judged by tracking the voltage,The practical application of frequency tracking algorithm in grounding fault is analyzed.
