DFIG-Based WT System Using FPWM Inverter

Abstract

In this work, we present a comparative study between fuzzy pulse width modulation (FPWM) and classical PWM technique in indirect vector command (IVC) of stator reactive power and stator active energy command of a doubly fed induction generator (DFIG) based wind turbine system (WTS). The obtained results showed that, the IVC using FPWM technique have current with low total harmonic distortion (THD) and more minimum electromagnetic torque ripple, stator reactive and stator active powers ripples then conventional PWM strategy.
