First, variable speed constant frequency wind energy convertion theory is described in this paper, then presents a review on the development of wind turbines control and the main types of generator and static converters used to interface variable speed wind turbines to the electric grid. then discuss main circuit constructure and advantage of direct drive wind energy conversion system and introduce pitch - control method for wind power traction and electric power stability. simply aerodynamic characteristic of the turbine is analysised and permanent magnet synchnonous generator math model is established. to convert the variable frequency electricity into utility grid, back to back four - quadrant pwm - vsi is used and three typies of control strategy is presented to capture the maximum wind energy and transmit energy. then simulation is implemented to test the control strategy. in the following chapter a simple ac - dc - ac converter with a dc - dc boosting chopper is proposed to transmit the wind energy into electricity energy and two control strategy is presented
建立了永磁電機和變流器的數學模型，針對雙pwm變頻器的特點提出了三種控制策略對變流器進行控制，通過變流器交-直-交的變換，將發電機發出的變頻變幅值交流電轉化為可用的恆定頻率的交流電，通過pwm調治能使其輸出功率因數為一，並且該控制系統功率因數為可調，能在特殊情況下同電網交換一定的無功功率，並通過對變流器的控制實現了最大風能俘獲的功能。最後採用matlab / simulink進行了模擬，取得了良好的模擬效果。在風力發電系統中，採用先進的最大功率俘獲演算法，能有效的從風中獲得最大的能量。
