A Better Control Strategy of Doubly Fed Wind Turbine

摘要：

　　Normally,doubly fed wind turbine use the method of looking up table in power control, it is reliable and can be realized easily,many famous manufacturers use it,such as MITA.Although its stability,it also has disadvantages such as narrow optimum working wind band and big power fluctuation in rated working stage.The article comes up with new control strategy,it broadens the wind band which comply the optimum tip speed ratio,improves the wind power though pitch control in the wind band which cannot comply the optimum tip speed ratio,increases the quality of output power though constant power control in rated working status,and enhance the security in high wind band by the introduction of the concept of optimum bitch angle.
