Abstract

Wind power generator based on Doubly Fed Induction Generator (DFIG) incorporates a back-to-back PWM converter. Filters are used to eliminate the harmonics produced by the PWM converter. However, very few papers have detailed the design procedure of the filters for a DFIG based wind power generator. A systematic procedure to design the LCL filters for DFIG back-to-back converter is proposed in this paper. Both filters for the grid side converter and the rotor side converter are designed. Simulations in PSCAD/EMTDC verify the effectiveness of the design procedure.
