Abstract
In this paper, the automatic location technology of short circuit fault in urban power system is studied deeply. In the introduction, the research background and significance, the research status and development trends at home and abroad, as well as the expected research results and application prospects are introduced. Then, the relevant concepts and theoretical basis are described, including the structure and operation principle of urban power system, the definition and characteristic analysis of short-circuit fault, as well as the basic principle and classification method of automatic short-circuit fault location technology. Then, the limitations and shortcomings of short-circuit fault location technology are analyzed, including the limitations based on traditional positioning methods, the shortcomings based on perception theory and the problems based on flow direction analysis. Finally, the limited solution of short-circuit fault location technology is proposed, including fault location method based on high precision monitoring node, hybrid location model and algorithm based on probability statistics and intelligent fault location system based on multi-source information fusion. This research is helpful to improve the security and reliability of urban power system and provide strong support for the steady state development of cities.
