As one of the important drawings, the electrical wiring diagram of the power grid is of great significance for power grid companies to plan new lines and solve line load problems. Due to the implementation of projects such as the optimization of grid lines and new construction, the electrical wiring diagram of the grid needs to be updated regularly, and as the scale of the grid expands, its content becomes more complicated and the workload of manual drawing will be greater. According to the drawing requirements of the electrical wiring diagram of the distribution network planning, an automatic drawing method of the electrical main wiring diagram of the distribution network based on DXF file content recognition and line identification is proposed, and the drawing system is modularized and parameterized in the AutoCAD VBA plug-in. Based on a project of China Southern Power Grid, this paper verifies the practicability and accuracy of the system.
