Research on digital transfer and correction technology for 3D model of power grid

The design drawings in power grid engineering construction usually need to be transferred to the equipment operation and maintenance stage. However, due to the differences between the actual construction process and the design drawings, manual adjustment has the problems of large workload and low efficiency. This article proposes the intelligent registration and reconstruction of power grid engineering data twins, which solves the problem of the lack of grid-based 3D point cloud data for modifying and adjusting the design drawings of substations in related technologies and improves the accuracy of operation and maintenance control after transferring the 3D design drawings to the operation and maintenance stage. This article studies the application of transfer model data in unmanned aerial vehicle inspection business for power transmission and transformation, improving the safety of unmanned aerial vehicle autonomous inspection and enhancing the reusability of transfer models by operation and inspection departments.
