Objective  The existing power grid GIS platform based on the geographical layout and the internal wiring diagram of the station building carries out the maintenance and business application support of the low-voltage station area data, which can not fully meet the application needs of the business department for further mining, refining and lean management of the low-voltage station area data information. In order to better support the relevant business applications of the low-voltage station area, it is urgent to carry out the low-voltage station area based on the low-voltage station area research on the application management mode of graph.

  Methods  Through the detailed analysis of the business requirements of the low-voltage platform area map, targeted research on the automatic mapping algorithm of the low-voltage platform area map was carried out to realize the automatic generation of the low-voltage platform area map; research on the automatic layout and automatic routing algorithm was carried out to realize the initial layout adjustment of the low-voltage platform area map through the intelligent layout and routing algorithm; research on the layout and routing adjustment tools to support the personalized users based on the electronic handover process, the incremental update of the low voltage table area map was realized.

  Results  Through the test and verification of the pilot power supply bureau, the automatic mapping technology of the low-voltage station area map realizes the automatic generation and initial layout and wiring of the low-voltage station area map, supports the manual layout and wiring adjustment of the low-voltage station area map, and realizes the flow-based incremental update and version management of the low-voltage station area map combined with the electronic transfer process.

  Conclusion  The automatic mapping technology of the low-pressure table area map greatly reduces the maintenance workload of the low-pressure table area map, ensures the timely and accurate update of the low-pressure table area map data, and lays a foundation for the lean management of the low-pressure table area.
