摘　　要：随着应用数量的增加,作为精确故障定位技术的行波测距已具备区域组网使用条件。文中在分析广域行波过程的基础上,扩展了双端行波测距原理以适应广域行波测距,提出了行波网络扰动有效区域的识别方法,构造了仅使用行波信息的完整的扰动记录数据筛选和校验,扰动线路的判断及扰动点定位的广域行波测距网络算法。现场应用验证了该算法的有效性。As an accurate fault location technology,the travelling wave location method has been widely used in the power system.With an increase of the number of the travelling wave devices,the travelling wave network can now be built.Based on a travelling wave propagation analysis,the double ends method is extended to suit the wide area travelling wave location.A scheme is proposed to obtain the effective disturbance area of the travelling wave network,and an algorithm is constructed simply using the travelling wave information.The algorithm can tell the disturbance line and give the precise location of the disturbance by selecting effective records.A field case shows the effectiveness of the algorithm proposed.
