In allusion to the defects of traditional method for the formation of topology inside substation and its updating efficiency, based on topological basis and radius search method a new method for the analysis on topology inside substation is proposed. Firstly, the node numbering is performed by basic concept of the graph theory and the circuit breakers are represented by nodes; on this basis, combining with the features of main electrical connection and the information of closed circuit breakers and utilizing the theorem of topological base the analysis on topology inside substation is performed. When circuit breaker status changes, based on radius search method the varied topology is modified to avoid the low updating velocity due to topology reformation, thus the efficiency of substation topology to trace the varied circuit breaker states can be evidently improved and the calculated amount of the proposed method is less than traditional methods. The validity of the proposed method is validated by experimental results.
