Mitigación de armónicos basado en el control predictivo de corriente mediante un filtro de potencia activo conectado al sistema de distribución

Abstract

The following document presents the investigation and analysis of the harmonic content that an electrical power system of 37 bars standardized by the IEEE can present, the simulation and analysis is carried out using the MATLAB/Simulink software, in which two scenarios will be analyzed in which the first point of study is the analysis of the influence of the non-linear load and the mitigation of the harmonic distortion in a node near the transformer, in this scenario the system will be analyzed in normal operating conditions, the node connected to a non-linear load and finally the application of the active power filter in the system with the non-linear load. The second scenario represents the influence of the non-linear load in a node far from the transformer, in this point of study the system connected to the non-linear load in a node far from the transformer will be analyzed and also the application of the power filter to the system with a non-linear load, for this scenario the analysis will be carried out in a node distant from the transformer, the study of a predictive control of current can also be carried out, which will reflect a signal in a quadratic way, trying to minimize the future error of the stream. The analyzes of the harmonic distortion that will be carried out in the test system will be analyzed and through the harmonic spectrum graphs it will be possible to observe the percentage of THD that they present throughout the simulation.
