Application of Transmission Line Scene Model Construction Method in Electric Power System

In view of the increasing demand of 3D model construction in digital twin application scenarios, there are already reverse manual modeling of laser point cloud of equipment department and GIM modeling of infrastructure department. Refined 3D modeling techniques such as transmission channels are relatively mature, but there are still many problems in the application. For the increasing construction requirements of 3D models for digital twin application scenarios, through the accumulation of laser point cloud reverse modeling, infrastructure GIM model and other transmission and transformation model libraries, data drive, CAD drawing image recognition, laser point cloud registration and other technologies, the technical breakthrough of parameterized model of digital twin 3D scene of power transmission and transformation is realized. This scheme meets the application requirements of differentiated 3D model accuracy, greatly saves the modeling labor cost, and improves the modeling efficiency.
