Abstract: A variable speed wind energy conversion system, with fuzzy control for efficiency optimization and performance enhancement, is discussed in this paper. A squirrel cage induction generator driven by a vertical axis wind turbine feeds the power to a utility grid through two double side pulse width modulated converter system. The generation control system uses three fuzzy controllers. The first fuzzy controller tracks the generator speed with the wind velocity to extract maximum power. The second fuzzy controller programs machine flux for light load efficiency improvement. The third fuzzy controller provides robust speed control against wind vortex and turbine oscillatory torque. The performance of the fuzzy controlled variable speed wind energy conversion system is evaluated through simulation study in MATLAB. Closed loop speed response of the generator with fuzzy controller show fast speed response can be obtained with well designed fuzzy controller.
