| 摘 要： | 分析了三相五柱式消弧线圈的工作原理和单相接地故障时各线路零序测量导纳的特征;结合该消弧线圈的补偿控制特点,提出了针对稳态接地故障的零序导纳增量最大值的接地选线方法;对于电弧性接地故障,利用故障时各线路零序暂态电流的特征,提出了暂态电流互积求和选线法;针对由电弧发展为稳态接地的故障,则综合利用上述两种方法进行综合选线。6kV电网模拟试验和挂网运行验证了该方法的准确性和可行性。

| Abstract: | The working mechanism of XBSG and the characteristic of the feeder measurement admittance in single-phase-to-ground fault are analyzed. The method of the maximum value of zero sequence admittance increment is proposed for steady fault based on the compensation characteristic of XBSG.According to arcing fault,the detecting fault feeder method using summation of mutual integral of transient current is presented by analyzing the characteristic of transient current.Compositive criteria is presented based on above-mentioned method for the steady fault which is developed by arcing fault. Through simulative single-phase ground fault experiment of 6kV and field running, this way had high precision. |
