Fuzzy Controllers for a high performance of the Doubly Fed Induction Generator based on Wind Turbine in variable speed

Abstract

This paper presents a nonlinear control of the doubly fed induction generator based on wind energy in variable speed. The turbine is equipped by two doubly fed induction generators (DFIG). The first one is controlled in order to keep the voltage and the frequency in the rates values. Then a Fuzzy Logic Controller (FLC) is used for power vector control regulation of the DFIG. The second one is connected when the power demand increase. But before the connection with the first generator, synchronization is done by a fuzzy regulator. Simulation results show the efficiency of our strategy.
