摘　　要：提出一种导线间距计算与三维可视化的实现方法。首先,建立合适的坐标系,确定连接输电线两端点的坐标和相关参数;其次,根据悬链线公式计算二维空间中悬链线上的坐标点,并通过旋转、平移变换,将各二维点转化到三维空间;然后,运用输电线路中的相关公式计算导线间的最短距离,基于BBD-Tree数据结构,运用了最近点搜索算法以提高计算效率;最后,应用空间样条插值曲线将悬链线及线间距三维可视化。依据提出的方案所编制的软件,计算快速准确,三维显示直观,并表现出很好的运行稳定性。Proposed a way to compute the phase spacing of translated lines. First,the correct coordinate system is founded. The coordinates of the points which would be joined and the parameters needed are decided. Second,the points of the translated lines are computed using the formula of catenary in the 2-dimensional space,the 3D points of the catenary are decided through transforming these 2D points. Then,using the related formula of transmission line conductor,compute the least phase distance. In order to improve the algorithm efficiency,the approximate nearest neighbor searching algorithm was used in the system based on the BBD-Tree data structure. Last,the 3D visualization of the translated lines is realized using the interpolated spines. The effectiveness of the software using this way to program is proved and showed good stability.
