摘要

摘要:本文提出了一种高精度、低计算成本的架空输电线路导线几何优化方法。该方法基于伴随法对输电线路电荷的灵敏度分析。该信息与梯度法和黄金分割算法一起使用，以使每相两根电缆的三相TL在地面上的电场最小。采用中心有限差分近似获得灵敏度，进行验证和比较。经过优化处理，得到了具有高浪涌阻抗负载的TL。

Methodology for Minimizing Electric Field at Ground Level from Transmission Lines Using Sensitivity Analysis

Abstract In this paper, a new methodology is applied to optimize the geometry of conductors of overhead transmission lines (TL) with high precision and low computational cost. This methodology is based on the sensitivity analysis of the electrical charge of the transmission lines using the adjoint method. This information is used with the gradient method and the golden section algorithm to minimize the electric field at the ground level of three-phase TL with two cables per phase. The approximation using central finite differences to obtain sensitivity is adopted for validation and comparisons. The TL's with high surge impedance loading is obtained after the optimization process.
