Composite Fault Location Method of Single-Phase-to-Earth about Rural Distribution Networks

摘要：

On the basis of introducing the rural distribution networks of single-phase-to-earth fault location method, a composite of fault location method of single-phase earth fault about rural distribution network is presented which integrate C-type of traveling wave location method with DC signal injection method. There are two steps in this method, in which firstly the fault distance is accurately located by C-type of traveling wave location method; then the fault branch is located by DC signal injection method. The proposed composite location method gives full play to the advantage of high location speed of traveling wave location method and that of low location error of DC signal injection method and has a good application prospect.
