Abstract

The invention provides a three-dimensional overhead cable hierarchical power grid optimization method and device and computer equipment. According to the three-dimensional overhead cable hierarchicalpower grid optimization method, multiple algorithms and technologies are fused to optimize a three-dimensional overhead cable hierarchical power grid; simulation construction of a three-dimensional overhead cable hierarchical power grid model is ensured; the multi-source geographic information data is managed through a tile partitioning technology; data access is facilitated, spatial indexing algorithm is used, and then an efficient index mechanism can be established; geographic space objects irrelevant to space operation in the three-dimensional scene are filtered; the space operation speed and efficiency are improved; a Bezier curve interpolation algorithm is used; and the rendering effect of the three-dimensional overhead cable hierarchical power grid can be improved, through the LOD algorithm technology, the original patch geometric model can be optimized according to different schedules according to different long-range close-range scenes, the number of topological edges and structural surfaces in the patch structure is reduced, and access and rendering efficiency of the model is improved.

Description

technical field [0001] The present application relates to the technical field of electric power grids, in particular to a three-dimensional overhead cable hierarchical power grid optimization method, device, computer equipment and storage medium. Background technique [0002] Due to the large number of grid equipment and facilities and the complex organizational structure, the two-dimensional plan cannot express the spatial relationship between the grid equipment and facilities intuitively and efficiently. Therefore, the technology of converting two-dimensional data into three-dimensional model data is becoming more and more important to the power industry more important. [0003] In recent years, 3D technology has developed vigorously, and has made breakthroughs in spatial position display, spatial data management, and spatial data analysis. It has been widely used in power systems and has played an important role in power production and management. played an important rol...
