Fault Detection and Identification Based on DFS in Electric Power Network

In this paper, we adopt a novel topological approach to fault detection and identification. In our researches, global information will be introduced into the backup protection system, we are using mainly DFS of graph theory algorithms to resolve fast and exact discrimination of faulty components and faulty sections, and finally accomplish fault detection and identification in electric power networks. Graph theory algorithms can be used to model many different physical and abstract systems such as transportation and communication networks, models for business administration, political science, and psychology and so on. In the study of fault detection and identification, graph theory algorithms must also have a good prospect of application.
