Regional Division Based on Smart Terminals and Localization Method of Power Distribution Network

Modern distribution networks are large-scale, structurally complex and interconnected, a comprehensive distribution automation system is required to monitor, manage and protect the distribution network. This paper focuses on the centralized fault interval localization based on topological structure classification. Based on traditional matrix operations, the improved algorithm divides different blocks according to the different connection relationships of the distribution network, the problems of large computational complexity and fault location blind zones in traditional fault localization is solved. The accuracy and efficiency of fault location are both improved in the regional division process. The corresponding diagrams of the distribution network are presented to verify the effectiveness of the algorithm and clarify the scope of application.
