摘要：
In order to fully make sure of fault location in distribution network, two necessities should be realized. The first is distance between head end of transmission line and fault location; the second is precise determination of the branch where fault occurs. These two points motive an identifying algorithm requirement that not only fault distance but also fault branch should be considered. This paper presents a fault branch identification method using single-ended injecting and multi-terminal detecting technique. This method is based on single-phase earth fault location scheme for distribution network, and further considers that incident wave of zero-mode voltage leads zero-mode and line-mode reflected voltage wave arriving at fault point simultaneously. Considering both zero-mode and line-mode enables the method to calculate fault distance and identify fault branch. Simulation based on PSCAD for different fault branches shows that the presented method is able to identify fault branch with high accuracy. © 2016, Power System Technology Press. All right reserved.
