Fuzzy logic control strategy of wind generator based on the dual-stator induction generator

摘要

The work presented in this paper is the evaluation of the variable speed wind turbine based on dual star induction generator (DSIG) connected for power optimization in the conversion chain connected to the electrical grid. This optimization is concretized by two methods, namely, the Maximum Power Point Tracking 'MPPT algorithm in the case where the characteristic of the turbine is known and the nonlinear method based on the theory of fuzzy logic controlled torque which is most appropriate when there is a lack of information on the characteristic (C_p(λ)) of the turbine. However, the limitation of power is performed by action on the generator control only. Simulation results are presented and discussed.
