摘要
二维GIS无法实现地形地貌展示、河流跨越分析、低洼区淹没分析等,因此电力线路三维可视化已成为国家电网工程信息化与智能化的热点和关键问题之一。然而,目前设计的三维单体模型缺少三维空间关系,不能直接表达三维电力线路。鉴于此,以某特高压输电电力线路为研究对象,首先对三维模型描述文件进行解析和地理编码,生成该电力线路的地理实体;然后通过地理实体与电力模型的挂接,实现电力线路的三维重建与可视化。结果表明,三维重建的输电电力线路中杆塔位置与实际相匹配,杆塔结构部分和导线连接位置正确,生成的导线与实际情景一致,整体输电电力线路三维重建效果良好。
2D GIS can not realize the terrain display, river crossing analysis, low-lying area submerges analysis, so the power line 3D visualization has become one of the hot spots and key issues of state grid engineering information and intelligence. However, the current 3D model lacks3D spatial relationship and cannot directly express 3D power lines. On the basis of this, taking an UHV transmission line as the research object,we analyzed and geocoded the 3D model description files, and generated the geographical entity of power line at first. Then, we connected the geographical entity to the power model to realize the 3D reconstruction and visualization of power lines. The results show that in the 3D reconstruction of transmission power lines, the positions of poles and towers are matched with the actual situation, the connection positions of poles and towers and wires are correct, and the generated wires are consistent with the actual situation. The overall 3D reconstruction of transmission power line has a good effect.
