The simulation study for Brushless doubly-fed generator wind power system based on fuzzy control

The approaching to achieve maximum wind-energy tracking control in terms of characteristic of wind turbine is studied in this paper. The mathematic model of Brushless doubly-fed generator (BDFG) is established in d-q synchronous reference frame. And decoupling control between active and reactive power BDFG generated is achieved. The fuzzy controller outputs the variation of active power in terms of the output speed turbulence until wind turbine operates at maximum wind-energy point. The simulation results are discussed to ensure the validity and feasibility of the proposal control strategy and to provide theoretical foundation for the application of BDFG-wind power.
