摘要
提出了一种基于反馈矩阵的馈线故障定位算法。根据馈线发生故障的历史记录,以及通信设备的可靠性,结合运行操作人员的经验生成反馈矩阵。通过反馈矩阵与SCADA系统采集信息的运算得到各个区段的故障概率,按照各个候选故障区段的概率数值大小进行排序,概率较大的区段就是故障发生可能性最大的区段。该算法充分利用了运行人员的经验,无需进行复杂的矩阵运算,同时能屏蔽SCADA采集信息的畸变,以极大的概率定位到准确的故障区段。
An algorithm for fault location of feeder line based on feedback matrix was proposed in this paper.According to the historical record of feeder line faults and reliability of communication equipment,in consideration of the experiences of operators,a feedback matrix was generated.By calculation of the feedback matrix and data acquired by SCADA,the fault probability at each section was obtained and sequenced in order from high to low.The section with high probability represents the high possibility of faults.This algorithm makes full play of the operators＇ experiences without complicated calculation of matrix and prevents data distortion acquired by SCADA,therefore,it has highest probability to determine accurately the fault location.
