A fuzzy logic controlled power electronic system for variable speed wind energy conversion systems

摘要

An intelligent power electronic system based on a fuzzy logic controller is presented for variable speed wind power conversion systems. The proposed scheme uses a fuzzy logic approach to control the electromagnetic torque for maximum power capture and dynamic performance improvement of the turbine-generator system. The system does not require the information on the wind velocity and can effectively limit electrical power fluctuations. Simulation results have demonstrated the effectiveness of the proposed method.
