| Abstract |
This article proposes the study and the simulation of a variable speed wind energy conversion system based on a doubly fed induction generator (DFIG). The DFIG is directly connected to the grid at the stator side and via a bidirectional converter at the rotor side. This configuration authorizes speed variations of ± 30 % around the synchronous speed and the converter is then dimensioned for a third of the nominal power of the machine. The wind variations are established using a spectral decomposition of the wind speeds and are applied to the model of the wind turbine. The model of this turbine is made using the traditional equations describing the mechanical operation of a classical horizontal wind turbine. The resulting torque reference is then applied to the DFIG which is controlled in order to obtain a maximum output power at each wind speed. |
