摘要
根据内蒙古四子王旗某地2007年逐月平均风速表选取设计风速为6 m/s,根据某型号300 W交流永磁发电机的输出功率特性,利用Matlab编写的叶片优化设计程序,设计了300 W水平轴风力发电机叶片。通过风轮与发电机的匹配,调整叶片参数,使之在小风时具有较高的风能利用系数,提高风力机的效率,在大风时具有较低的风能利用系数,从而达到大风时限速保护的目的。
According to monthly average wind speed of 2007of Siziwangqi in Inner Mongolia, design wind speed was selected as 6 m/s . 300W horizontal axis wind turbine blades were designed using the blade design program written by MATLAB,based on power output characteristic of a 300W permanent magnet generator. According to the matching characteristic of turbine and generator, refining blade parameters, the power coefficient is higher when wind speed is lower than rated vahle_ and the nower coefficient is lower in high winds.
