Abstract :
In this paper a system to evaluate a variable speed and pitch angle wind turbine by fuzzy logic techniques is described. A fuzzy logic control has been proposed based on the wind speed estimation in order to get maximum power and stability of the system. An 11 kW prototype system using two inverters connected by a DC-link capacitor has been used: the first one works as a controlled rectifier implementing vector control and the second one handles the power injected into the utility grid. Experimental result of an 11 kW generator are shown
