Abstract

This paper presents a computational tool intended to calculate and minimize the electric 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 utiliza-tion of multiple conductors per phase. In the present work, a Differential Evolution Method is applied to find an optimized transmission lines with non conventional configuration for the phase conductors with reduced electric field profiles at ground level. The surge impedance loading of the transmission lines before and after the optimization process are calculated.
