Diseño de un filtro activo para control de armónicos a la salida de un aerogenerador de inducción de doble alimentación

Abstract

The main objective of this article is the control of harmonics and reduction of THD, generated by the implementation of a non-linear load and a double-feed induction wind turbine, with the help of the simulation and analysis of an active filter designed purely for the reduction of harmonics at the output of a double-fed induction wind turbine connected in a system IEEE 37 bar electric power. The analysis was carried out by comparing articles that aim to reduce harmonics by implementing hybrid filters, which was analyzed, and it was possible conclude that the filter presented below better complies with the reduction of harmonics and therefore corrects the total distortion harmonic without having the robustness of a hybrid filter. The advantages of the implementation of active filters are to eliminate heavy and expensive inductances. In the same way, they allow the design of complex stages using simple steps for their operation, and they can be coupled to impedances without the need for other elements for their tuning. In the implementation of the filter, two specific scenarios are presented, which are the following: a study in a stable state and a in a transient state. This article contributes to the study of distribution problems with the implementation of wind generation, giving a more viable and straightforward contribution.
