Desarrollo de una Herramienta Computacional para Mitigación de Armónicos de Corriente en un Sistema Industrial Monofásico de Baja Tensión Mediante la Eliminación Selectiva de Armónicos

Abstract

This document contains a proposed method for current harmonic attenuation in single-phase industrial systems, up to 16 Amperes, of low tension by means of the strategy of selective harmonics elimination. It is developed starting from a process of classification of single-phase typical loads to the model of load rectifier, condenser and resistance; there proceeds to carry out a model of Matlab who allows to validate the measurements obtained in the process of classification with the model of rectifier to different values of load; where in addition there is realized the implementation of the different commutation signals for the investor of active filter and the different algorithms of the function fsolve for the solution of the matrix model of the system of nonlinear loads. Simulations are realized to establish the best commutation signal and the algorithm that presents the best results, finding as better sign of commutation the SLN2 that has voltages (170, 0 and +170 V) and the algorithm Trust Region Dog Leg. They are evaluated near 4.500 loads(charges) by the resultant system, evaluating the results obtained with regard to the norm IEC 61000 3-2 for systems of low power in elements of A class.
