Diseño y simulación del control de un filtro activo monofásico paralelo

Abstract

The present project the design and modeling of a single-phase shunt active filter, which is intended to compensate harmonic currents in a distribution network with different nonlinear loading conditions through simulations using Matlab/Simulink. It is mentioned briefly the loads that are a source of harmonic currents, the problems that involve this type of load and the regulations established to control the energy quality concerning to the harmonic distortion of current as well as the theoretical foundations for the development of this project. Then there is the topology chosen to the model of active filter and the rating calculation of the basic elements. Subsequently, the technique of hysteresis current control is used for the active filter to follow the reference of compensating harmonic currents with a constant ripple, and the design of a voltage regulation control to maintain a constant voltage of the DC-bus for a half-bridge inverter that is responsible of providing current compensation to the network. Finally simulations are being performed to observe the behavior of the filter under different loading conditions.
