DFIG-Based Wind Turbine System using Four-Level FSVM Strategy
Abstract—Traditional direct vector command (DVC) structures which include proportional-integral (PI) regulators of a doubly fed induction generator (DFIG) driven have some disadvantages such as parameter tuning complications, mediocre dynamic performances and reduced robustness. Thus, based on analysis of the DFIG model supplied by new modulation technique, this article addresses a four-level space vector modulation (SVM) based on fuzzy logic algorithm (FSVM). The classical DVC command with SVM technique has large ripples on the stator active and stator reactive developed by the DFIG. In order to solve this disadvantage, the DVC command with FSVM technique is proposed. Simulation results show the effectiveness of the proposed command scheme especially in power ripples behavior, reference tracking test and robustness against generator parameters variations.
