Simulation of Low Frequency Electromagnetic Fields in 132kV Overhead Transmission Lines Using 2D Finite Element Analysis

Abstract

In order to improve the compatibility of high voltage transmission lines with the environment, it is necessary to consider the effects originated by the visual impact, the corona effect that causes radio interference and audible noise, noise and low frequency electromagnetic fields, among others. The objective of this work is to study, model and verify that transmission lines comply with the current Argentinian standards that set the limits of low frequency electromagnetic fields exposure, in order to reduce environmental impact and ensure the safety of people, animals and/or facilities. FEMM software will be used to carry out the proposed verification. This software is able to perform 2D modeling and simulation of electromagnetic and electrostatic circuits using finite elements method. Several case studies are considered, where simulations are proposed under different load conditions with nominal voltage of 132 kV according to typical tower construction arrangements in Argentina. The results obtained will be evaluated according to the current Argentinian Standards.
