Research and Application of Substation Operation Safety Management and Control System Based on Three-dimensional Modeling and Composite Positioning

This paper presents a substation operation safety management and control system based on three-dimensional modeling and composite positioning technology. Which is based on difficult management and control of operators, vehicles and tools and instruments, low efficiency, narrow dimension and blind spots in the current substation field operation. The system takes three stages before, during and after the on-site operation of the substation as the key points. Firstly, the laser point cloud and BIM are used for 3D modeling. Then use Beidou and UWB composite positioning technology, combined with substation intelligent access control, video monitoring, work ticket and other subsystems. Realize the functions of personnel and vehicle qualification review before substation operation, real-time positioning of personnel and tools and instruments during operation, recovery of safety measures after operation and real-time monitoring of items left behind. The system has been successfully deployed and applied in a 220kV substation in Guizhou, which greatly improves the efficiency of on-site operation safety management and control of the substation.
