摘要
分布式电能质量监测系统中,为实现电能质量扰动源的准确定位,提出电能质量扰动源定位的矩阵算法。首先,建立电能质量监测点与线路关联关系的监测关联矩阵;当检测到扰动事件发生时,由各个监测点的扰动方向判别结果建立扰动方向矩阵;最后将监测关联矩阵与扰动方向矩阵对应元素相乘获得扰动判断矩阵,从而准确判断扰动源的位置。该算法原理简单、定位准确,适用于对各种类型电能质量扰动源进行定位。
In a distributed power quality monitoring system,for the realization of the power quality disturbance source exact location, thematrix algorithmof the power quality disturbance positioning is proposed.First,the monitoring incidence matrix is established by the corresponding relationship between the power quality monitoring points and lines;When the disturbance event is detected, the disturbance directions matrix is established by discrimination results of the disturbance directions from each monitoring points; Finally,the corresponding elements from the monitoring incidence matrix and the disturbance directions matrix are multiplied to establish the disturbance judgingmatrix,and thus accurately determine the position of the disturbance source.The proposed method is simple and accurate,suitable for all types of power quality disturbance source position.
