Research on Decision-Making Method of Line Fault Recovery Based on Knowledge Map

This paper presents a decision method for line fault restoration based on knowledge map, and gives a knowledge inference software framework for line trial transmission restoration. The method first constructs the knowledge map of the line fault restoration decision-making. Then monitors the line operation status in real time to collect the real-time information of the faulty line; determines the power loss bus and its connected switching equipment according to the topological relationship. Based on the constructed line failure restoration decision knowledge map, determine whether the line has forced power transmission conditions, and if so, perform forced power transmission, otherwise arrange line power transmission after line inspection. After successful power transmission, first conduct a trial power transmission to the bus of the station close to the fault point, after the bus trial transmission is successful, the bus ring closing process is carried out, and finally the bus on the other side of the faulty line shall be re-powered. In this paper, by constructing the knowledge map of the line fault restoration decision and combining the line fault data, the scientific judgment and analysis of power recovery decision after line faults can deal with line faults timely and effectively.
