三维送电线路GIS系统在电力线路勘测路径选择中的应用

Application of GIS in Selection of Line Path During Electric Power Line Surveys in Three-Dimensional Transmission Line

GIS系统可提供在高精度的三维真实地形地貌虚拟环境下漫游、查询设备台帐、沿线路飞行、选择线路路径、优化塔型及塔位和输出设计结果等功能。借助于该系统,可以将部分路径优化工作提前到规划可研阶段进行,能够使路径走向更加合理。由于GIS系统采用高分辨率的卫星影像图,在设计线路时可以很好地避开房屋以及其它特殊地物,择优出一个比较经济合理的方案来,从而减少后续勘测设计返工,加快设计进度,为线路顺利施工、投产运营奠定良好的基础。

Geographic Information System can provide, in the true high-precision three-dimensional virtual environment, topography roaming, equipment account inquiries, flying along the road, choose the path lines, and optimize the tower and tower-based and output the digital design. With the system, you can optimize part of work of the path planning in advance to the feasibility study stage, and make the path toward more reasonable. Baesd on the high-resolution satellite image maps, Geographic Information System can as far as possible to avoid the housings and other special features in the selections of design circuit, and choose a more economical and reasonable solution and then reducing rework the design of the follow-up investigation, and speed up the design progress.
