Comparative Study Between PWM and SVPWM Technique For a DFIG-Based Wind Turbine System Controlled By Fuzzy Sliding Mode

In this paper, we present a comparative study between pulse width modulation (PWM) and new space vector pulse width modulation (SVPWM) technique in fuzzy sliding mode control (FSMC) of reactive and active power command of a doubly fed induction generator (DFIG) for wind turbines. Two commands approches using FSMC-SVPWM and FSMC-PWM are proposed and compared. The validity of the proposed commands schemes is verified by simulation tests of a DFIG. The reactive power, stator current and active power is determined and compared in the above techniques. The obtained results showed that, the proposed FSMC with SVPWM technique have reactive and active power with low powers ripples and low stator current harmonic distortion than PWM technique.
