摘　　要：设计了适用于广西北部湾海域的4MW风力机的气动参数。建立了风力机数值模型,分析了风力机的气动性能;计算了风力机风能利用系数与叶尖速比和桨距角的关系,得到了最优风能利用系数和最佳叶尖速比;基于广西北部湾海域实测风速数据计算得到该地区的威布尔分布参数,采用威布尔方法确定风力机额定风速;利用FAST计算得到额定风速下的额定功率为4MW,基于变速变桨的控制策略进而得到了额定转速等气动参数;基于实测风速,计算了所设计4MW风力机2021年和2022年发电量。结果表明,该4MW风力机具有良好的发电性能。The aerodynamic parameters of a 4MW wind turbine applicable to the sea area of Beibu Gulf of Guangxi were designed.A numerical model of the wind turbine is established,and the aerodynamic performance of the wind turbine is analyzed;the relationship between the wind energy utilization coefficient of the wind turbine and the tip speed ratio and pitch angle is calculated,and the optimal wind energy utilization coefficient and the optimal tip speed ratio are obtained;based on the measured wind speed data of the Beibu Gulf sea area of Guangxi,the parameters of the Weibull distribution of the area are obtained,and the Weibull method is adopted to determine the rated wind speed of the wind turbine;the rated power of 4MW is obtained at the rated wind speed by using FAST,and the rated rotation speed is obtained based on the control strategy of variable speed pitch;based on the measured wind speed,the power generation of the designed 4MW wind turbine in 2021and 2022is calculated.The results show that the 4MW wind turbine has good power generation performance.
