Fuzzy Logic Control Based Grid Integration of Doubly Fed Induction Generator Using Matrix Converter

摘要

This paper deals with the modelling and control of a grid integration of wind energy conversion system (WECS) based on a Doubly Fed Induction Generator (DFIG) served by a matrix converter. Instead of back to back converter, the matrix converter can be more suitable for connecting theDFIG rotor into grid. The proposed system has been developed and simulated in Matlab environment and analysis of the system performance without rotor current controller. The DFIG and converter model has been used to calculate the performance of rotor current based on the simulation results.Fuzzy logic controller helps to reduce the errors between rotor current and reference current for each of the valid states of the converter. The proposed controller has been developed by simulation in Matlab and implemented to the rotor current control for DFIG. The simulation results areanalysed and compared to with and without fuzzy controller. Finally the simulation results are evaluated with IEEE 1547 standard for proving the effectiveness of the proposed system.
