摘　　要：近年来,三维数字化设计技术已经逐步应用于配电网线路工程的设计,在路径选择和优化中体现了技术优势,提升了设计水平和效率。工程设计需要逼真的空间仿真场景,设计场景的地理信息需要加载大量的地形图数据,但是由于不同数据的格式和精度存在差异而加载困难,导致场景失真,影响设计效果。文章提出了工测数据和矢量地形图与基础地理数据融合的方法,提高了设计场景地理信息的精度,同时通过三维虚拟实现了配电网工程场景的高精度仿真,为配电网三维数字化设计的实现提供了满足工程精度要求的仿真设计条件。In recent years, 3D digital design technology has been gradually applied in the engineering design of distribution network line. It has technological advantages in path selection and optimization, improving the design level and efficiency. Engineering design requires realistic space simulation scenarios, the design of geographic information needs to load a large number of topographic map data. However, due to the differences in the format and accuracy of the different dat, the load is difficult, leading to scene distortion and poor design effect. A method that combines test data, vector topographic map and basic geographic data is proposed to improve the accuracy of the design scene geographic information. The high-accuracy simulation of distribution network project scene is realized by 3D virtual, providing simulation design conditions to meet the accuracy requirements for the realization of 3D digital design of distribution network.
