Design and implementation of a 3D digital platform for transmission lines in power transmission and transformation engineering

摘要

随着特高压输电工程规模的不断扩大,输电线路途经区域的地理环境日趋复杂,传统二维设计手段在应对地形地貌、生态环境及施工成本等多重约束时,逐渐暴露出路径规划不直观、数据整合困难、设计效率低下等问题。针对上述挑战,设计并实现了一套输变电工程输电线路三维数字化平台。该平台结合三维地理信息系统、卫星遥感技术和众多的3D设计软件,可以进行输电线路的可视化设计。研究利用该平台对复杂的地理信息进行采集,然后利用加权栅格矩阵对建设的三维地理信息进行建模,接着以最低建设成本和最高收益为目标,使用Q值算法对输电线路的最优路径进行规划。最后将其应用到华东-华北特高压直流输电工程中取得了显著效果。以A1-1路线为例,结果显示,平台设计的路线比原计划路线节约成本约102.6 万元,缩短工期16 天,可以极大减少输电线路的设计成本,缩短设计时间。

Abstract

With the continuous expansion of the scale of ultra-high voltage transmission projects, the geographical environment of the areas where transmission lines pass through is becoming increasingly complex. Traditional two-dimensional design methods gradually expose problems such as lack of intuitive path planning, difficulty in data integration, and low design efficiency when dealing with multiple constraints such as terrain, ecological environment, and construction costs. In response to the above challenges, a three-dimensional digital platform for transmission lines in power transmission and transformation engineering is designed and implemented. This platform combines 3D geographic information systems, satellite remote sensing technology, and numerous 3D design software to enable visual design of transmission lines. The research utilizes this platform to collect complex geographic information, and then models the three-dimensional geographic information constructed using a weighted grid matrix. Then, with the goal of minimizing construction costs and maximizing profits, the Q-value algorithm is used to plan the optimal path of transmission lines. Finally, it was applied to the East China North China ultra-high voltage direct current transmission project and achieved significant results. Taking the A1-1 route as an example, the results show that the platform designed route saves about 1.026 million yuan in cost and shortens the construction period by 16 days compared to the original plan route. The research and design platform can greatly save the cost and shorten time.
