摘要
馈电线路发生故障时,故障区段必然位于两个相邻负荷开关之间的线路上,通过馈线终端单元采集故障信息上报SCADA系统,得到负荷开关上馈线终端的有关故障信息序列,利用故障信息进行故障区段定位。建立基于概率条件下的故障区段定位模型,利用发生故障时的最大故障概率这一条件进行故障区段定位,简单可靠。
As the distribution lines are found faulty, the fault section must be located between two breakers. This paper analyzes the information of breakers, coming from SCADA system, to detect the fault section. Based on fault probability, a method of fault detection is proposed, according to the maximum fault probability to find the fault location. This method is simple and reliable,
