Diseño y comparación mediante simulación de dos técnicas de control PI y SMC para el Filtro Activo Trifásico de tres hilos en Topología Paralelo

Abstract

In recent years the rapid development of power semiconductor technology and the extensive use of electronic equipment have led to a significant increase in electromagnetic disturbances in the electrical distribution system. Thus, distribution companies are increasingly interested in mitigating the growing problems of energy quality as their technical and economic losses are increasingly significant. In the present project, these problems are solved with a three-phase active filter. Two methods of harmonic identification PQ and DQ will be used which will be used to obtain the harmonic components of the electrical distribution network, obtaining the harmonic current reference which will enter the PI and SMC controllers, these will be responsible for sending the optimal signal of switching to a three-phase voltage inverter which will inject inverse signals to the reference harmonic currents, mitigating the total harmonic distortion of the distribution network. The verification of the compensation of the harmonics of current will be made by the parameter THDI complying with the IEE 519-2014 standard.
