A new fuzzy logic controller to improve the captured wind energy in a real 800 kW variable speed-variable pitch wind turbine

This paper presents an application of fuzzy controllers for improving the captured wind energy and the performance of variable speed wind turbines using fuzzy controllers. The simulated fuzzy model has been satisfactorily implemented using a programmable logic controller as the designed fuzzy controller. Transition between power optimization and power limitation of the wind turbine is greatly improved especially in the rated wind speed working conditions. Fuzzy controller also permits to increase captured wind energy in low and high wind speed.
