Abstract

A wind energy conversion system (WECS) based on doubly fed induction generator (DFIG) and matrix converter is presented. We developed a new robust control law for the active and reactive stator powers with sensorless stator current, contrary to control methods given in the literature where all stator and rotor currents are necessary. The rotor flux and stator powers, required to control the DFIG, are determined through the proposed sliding-mode observer. Three main benefits come out of our law including robustness, low cost and the possibility of supervising the converter through rotor current measurements. Simulations of the considered WECS are carried out, for different operating points, to highlight the performances of the proposed system.
