Research and Engineering Application of Automatic Single-line Diagram Generation for Distribution Network Feeder Areas

The distribution network substation area serves as the terminal unit for power distribution and supply services, with the single-line diagram being a core drawing document for operation, maintenance, and repair tasks. Traditional manual drawing methods suffer from low efficiency, significant errors, and delayed updates, making them inadequate for the demands of intelligent distribution network construction. This paper focuses on the research of automatic single-line diagram generation technology for distribution network substation areas, outlining its core components and key technical points. By integrating practical engineering scenarios, it analyzes the specific applications and implementation outcomes in areas such as distribution network operation, ledger management, and fault handling. The aim is to promote the adoption and implementation of automatic diagram generation technology, enhance the digital and intelligent management of distribution network substation areas, and strengthen foundation for secure and stable operation of distribution network.
