快速实现输电线路杆塔排位优化的方法

Method of Fast Pole and Tower Arranging Optimization for Transmission Lines

在输电线路设计过程中利用计算机进行杆塔排位优化时,对大规模集成的软件还是显得速度不够。在采用计算机进行输电线路排位过程中,通常是假设塔位、塔高来计算电线的弧垂以确定电线在档内各点的位置,从而校验电线各点对地面及地面设施的距离。在此计算方法中,公式含有双曲线函数,计算复杂,计算机运行时间较长。对此计算方法进行优化,可以大大缩短软件的运行时间,提高工作效率。误差分析结果表明满足工程设计要求,该方法在杆塔排位优化及送电线路决策软件中应用效果比较满意。

In transmission line design, when large comprehensive software is used in pole and tower arranging optimization, extra fast computers are needed. In arranging calculation, normally, tower locations and heights are assumed to calculate line sag so that the location of the cable within every span can be determined to check the clearance between the cable and ground or ground facilities. In this method, formulae contain complicated hyperbolic curves, resulting long CPU time. The calculation time can be significantly reduced by optimizing this method. Error analysis show that results meet engineering design requirement. The method has satisfactory results in pole and tower arranging optimization and line decision making software.
