@@@@本文利用全站仪进行输电线悬挂点坐标非接触测量，根据测量得到的三维坐标，采用Visual C++6.0计算输电线应力、弧垂与长度以实现，由OpenGL完成输电线三维空间形态布局模拟。利用OpenGL的坐标变换、深度缓存、双缓冲等技术，可从多视角全方位观察输电线布局模拟效果，画面流畅，能够真实地显示输电线设计效果，避免设计错误的现场出现、降低了工程造价；同时替代人工快速计算相应档距的弧垂及线长，提高了工作效率、克服了人为误差。

In this paper, Total Station is used to measure the suspension point’s coordinate of transmission line in a non-contact way. Visual C++ 6.0 work out the stress, sag and wire length of transmission line based on three-dimensional coordinate, and then OpenGL completes the three-dimensional shape layout simulation of transmission line. The technology of coordinate transformation, depth buffer and double buffering provided by OpenGL makes it available to observe simulation effect from omni direction and multi-vision in smooth pictures. It can truly show the transmission line’ design effect , avoid the design errors committed on the actual site and reduce the construction cost;the system also replace the human to work out the sag and wire length of corresponding span promptly, thus improve the working efficiency and overcome artificial error.
