Variable Structure Control Applied in Wind Turbine Based on Induction Generator

Abstract- In this paper, the wind electrical conversion system (WECS) is described; the structure of WECS is based on the Induction generator. The global model of the WECS is presented. A study of the electrical parts (Induction machine and static converter) is developed. The goal of this paper is to control the power generated by the WECS to the grid. A strategy of control is developed signed based on the vector control applied to Induction Machine. A new controllers are designed using sliding mode techniques to control active and reactive power. Simulation study was done to prove the validation of the strategy and the method of control used in power control. Conclusions are summarized in the last section
