Análisis armónico en la red de distribución eléctrica para determinar los efectos de la inclusión de vehículos eléctricos usando transformada de Wavelet y Hilbert Huang

Abstract

Electric vehicles are an alternative to replace conventional combustion vehicles, contributing to the reduction of emissions harmful to the environment. The replacement of conventional vehicles with electric ones implies a greater electrical demand. It is necessary that the electrical grid is robust enough to withstand the increased load that electric vehicles would imply. In addition, the nature of the load is non-linear, which can cause harmonic problems in the electrical network. Therefore, “it is necessary to carry out a study to analyze the impact of harmonics on the electric network”, as well as the quality of energy with the electric vehicle included in the network. To achieve the harmonic analysis of the network, the electric vehicle owned by the Salesian Polytechnic University is used, with the help of a Fluke meter, measurements of the network are made, which will serve as data to perform the analysis using the Wavelet transform Hilbert Huang to quantify them in order to determine which analysis is more accurate. To do this, the network is broken down in order to visualize the harmonics present in it, to compare with the levels allowed in the IEC standard and determine if they are at acceptable levels for normal operation.
