direct vector control of a dfig supplied by an intelligent svm inverter for wind turbine system

This article presents an improved direct vector command (dvc) based on intelligent space vector modulation (svm) for a doubly fed induction generator (dfig) integrated in a wind turbine system (wts). the major disadvantages that is usually associated with dvc scheme is the power ripples and harmonic current. to overcome this disadvantages an advanced svm technique based on fuzzy regulator (fsvm) is proposed. the proposed regulator is shown to be able to reduce the active and reactive powers ripples and to improve the performances of the dvc method. simulation results are shown by using matlab/simulink.
