Fuzzy Logic Control Based Matrix Converter for Improvement Output Current Waveforms of Wind Turbine System

Abstract

The evolution of the efficiency of wind farms is very recognized in the production and use of renewable energy in the countries concerned by this new trend. The converters currently are an essential means in the performance of DFIG (Doubly-fed induction generators) in wind turbines Doubly-fed induction generators. In this paper an associated passive RL load – matrix converter under supply voltage connected system is studied. The influence of disturbed input supply voltage on output current waveforms has been discussed. We aim to extract sinusoidal output current waveforms, the conventional PWM methods and the optimum Venturini method with fuzzy logic control approach can be applied for controlling the matrix converter. Finally, Simulations results will be presented and interpreted, and a special attention is given to suppressing harmonic pollutions using total harmonic distortion evaluation.
