Disminución del THD con la implementación de un control para un filtro de potencia activa con derivación monofásica en sistemas de distribución con alta penetración de cargas no lineales

Abstract

This document details the characteristics of the non-linear loads that are connected within the electrical distribution systems and they are defined according to the type of load to which they belong, these being the main elements of generation of harmonics (THD) towards the net. In the document, a control for an active power filter with single-phase shunt (SPAFs) is proposed as an effective solution to lower THD. It should be taken into account that SPAFs are single-phase passive filters that are connected in series and due to their components it is shown in the system as an additional component, for this reason it is proposed to implement three-phase capacitor banks that are capable of maintaining the profiles of voltage in acceptable values, improving the quality of power due to the electrical phenomenon that occurs due to harmonics. It is also detailed that in this document four case studies are shown where the serial implementation of the SPAFs is carried out together with the bank of three-phase capacitors on the IEEE 14-bar AC / DC hybrid system. bars with a greater harmonic problem, finally a comparison will be made regarding the percentage of THD as the main variable, all the work will be simulated in MATLAB / SIMULINK, this being a program to validate results using graphs and tables.
