摘　　要：在主导风向下,考虑尾流效应,采用不同的风力机布置形式,比较风力机总产能,进而得出风力机沿主导风向单列布置的优化模型。在有限的长度范围内,随着沿主导风向布置的风力机间隔的减小,风力机总产能增大。文章研究了采用不同的威布尔参数k和c对风力机总产能的影响,在风力机间隔不变的情况下,形状参数k增加会导致风力机总产能的减少,尺度参数c增加会导致风力机总产能的增加。Considering wind turbine wake effects,a model for optimal placement oi wlna mrnmes m single-line along prevailing wind direction has been developed. Through the example analysis of the wind power output with different placement schemes of wind turbines, it is concluded that the wind power output will increase with wind turbine spacing in the direction of prevailing wind within the lim- ited boundary of wind farm. The impact of the Weibull distribution parameters k and c on wind power output is also discussed and studied. The power output is presented a decrease trend with increasing value of k, which is quite opposite to the value of c.
