Abstract: With the large-scale integration of intelligent devices, the structure of the distribution network is complex and the topology is constantly changing. In order to meet the increasing demand for data collection and analysis in the intelligent distribution station area. This article proposes an intelligent circuit breaker topology recognition technology based on the multi branch tree algorithm. By activating the adaptive recognition function of circuit breakers in the control panel area, the multi branch tree algorithm is applied to analyze the feature recognition results, realizing the self recognition function of circuit breaker topology in the intelligent distribution station area. The topology recognition results are uploaded to the distribution cloud master station, solving the contradiction between untimely topology updates in low-voltage distribution networks and the inability of the cloud master station to display visualized station area information.
