Description

The maximization of wind energy extraction can be obtained using variable speed electrical generators in conjunction with non linear control algorithms. This paper presents an incremental speed control method which is independent from both wind speed measurement and specific systems characteristics. The algorithm is based on the dynamic behaviour of the electrical generator and uses fuzzy logic as a non linear reasoning tool. The simulation results obtained with this controller applied to a double feed induction generator show that it is possible to increase the efficiency in the conversion from wind power to variable speed and torque.
