Análisis del problema SSR (Resonancia Sub-síncrona) en generadores eólicos de la configuración DFIG en una micro-red

Abstract

This document presents a description of the wind generator DFIG configuration to know the structure, operation and main inconveniences caused in the Micro-grid connection. The implementation is based on a 13 bars model with distributed generation cited from the IEEE publisher in connected mode to the main network, three case studies are proposed to visualize different scenarios and to get better results in the analysis of DFIG behavior in a Micro-grid. In addition, loads with maximum and minimum values will be used to improve the filter of the DFIG model. A comparative analysis is made taking into account two aspects, the voltage levels in all busbars and the presence of harmonics of order 3, 5, 7, 9 by means of graphs, tables and bar diagrams. The graphical model for obtaining the results is made using a discrete block in Simulink. Finally, it is determined that the DFIG model improves conditions in a Micro-grid and is the best option compared to other configurations of wind generators.
