Study on power control of doubly fed wind turbine

This paper firstly introduces the system model of wind turbine. According to the input mechanical energy and the power curve of wind turbine, we study the Steady-state Characteristics, relationship of the power and turque. Then the power output characteristic of the wind turbine is simulated by MATLAB.The simulation result shows that the Double-Fed Induction Generator(DFIG) system can realize optimal power output-functions by adjust the power factor especially under the rated speed, then it can obtain maximum power output, this is a effective way to improve the efficiency of the wind turbine. This paper provide a reference of control strategy design of the wind turbine.
