Abstract:

Distribution network line fault is complex. It is difficult to automatically locate the fault of distribution network quickly and accurately. The fault location technology is mainly focused on two core technologies: fault line selection and fault location. This paper presents an expert system for fault location in distribution network based on transient characteristics, which firstly introduces the method of line selection based on transient zero sequence current comparison method, and gives the specific steps of selecting the line. Then, it designs the communication structure and the expert system of distribution network line fault location based on the transient characteristics of the distribution network line fault detection and information management system.

Key words: Distribution network line, fault location, transient zero sequence current algorithm, expert system
