【 摘 要 】

Abstract: In this paper, we present a grid-connected wind turbine equipped with double-fed induction generator directly connected to the grid in the stator side and interconnected via a power converter in the rotor side. Then we present a fault tolerant control (FTC) based on sliding mode observer for stator winding fault of DFIG. We develop an algorithm that allows the passage from nominal controllers designed for healthy condition, to robust controllers designed for faulty condition. Simulation results have shown good performances of the system under these proposed approach strategies.
