Fault Detection Techniques of Distribution Net Based on Conditional Probability

摘要: 配电线路故障时 ,故障点必然位于两个相邻近的负荷开关之间。通过SCADA系统采集到负荷开关的故障信号序列进行故障定位寻址 ,建立基于条件概率下的故障寻址模型 ,在最大故障概率条件下进行故障定位 ,并通过算例验证了其正确性 更多还原Abstract: As the distribution lines get fault, the fault point must be located between two adjacent load switch. This paper analysed the single sequence of load switch, which gets by SCADA system, to detect the fault place. Based on fault probability, a method of fault detection was proposed, according to the maximum fault probability to decide the fault location. Examples were given to verify its correctness.
