New Arrangements of Overhead Power Line Phase Conductors Achieved by Multiobjective Non Dominated Sorting Evolutionary Method

Abstract

This paper presents a computational tool intended to calculate and minimize the electric and magnetic fields at ground level of High Surge Impedance Loading Transmission Lines. This type of transmission line achieves higher power transmission rates by utilizing optimized configuration for the phase conductors. This method is advantageous over other actions taken by the utility company such as increasing the maximum operation temperature of the line, increasing the size of the conductors or the utilization of multiple conductor per phase. In the present work, a Multiobjective Non Dominated Sorting Evolutionary Method is applied to find a non conventional optimized configuration for the phase conductors with reduced electric and magnetic field profiles at ground level.
