Adjoint Method Applied in Optimization of the Overhead Transmission Lines Configuration

Abstract

In this paper, a new methodology is applied for the optimization process of the geometry of the bundle of conductors of the overhead transmission lines. This methodology is based on the application of the Adjoint Method to calculate the sensitivity of the parameters related to the charge electric of the transmission lines. This information is used with a Gradient Method and a Gold Section algorithm for the minimize the electric field at ground level. The Surge Impedance Loading is calculated after the optimization process for check improvements in energy capacity transportation.
