摘　　要：本发明公开了一种在满足输电线路绝缘要求和线下空间电磁环境限值要求的前提下，使超/特高压输电线路下方空间的工频电磁环境最佳的线路结构寻优方法，主要内容包括：输电线路下方空间工频电场和工频磁场的计算；基于粒子群寻优算法的线路结构寻优。本发明方法适用于所有高压输电线路结构类型，具有计算速度快、精度高等特点，对于优化超/特高压输电线路结构设计将是一个有用的工具。

主权项：1.一种优化超/特高压输电线路电磁环境的结构设计方法，其特征在于，包括以下步骤：101、获取超/特高压输电线分裂导线数n1、分裂子导线半径r及分裂圆半径R，并根据公式(1)计算得出每相导线的等效半径R_i；102、预设第n相、第m相导线的坐标位置分别为(x_n,y_n)、(x_m,y_m)，分别求得第n相导线与第m相导线间的距离以及第n相导线的镜像导线与第m相导线间的距离并代入步骤101中求得的每n相导线的等效半径R_n，根据公式 $\begin{matrix} p_{nn} = \frac{1}{2 π ϵ_{0}} \ln 2关键词：法律状态：公开IPC专利分类号： G06F17/50(2006.01)Ivar ShareData = new Array();
