摘　　要：针对立轴风力机起动性能差和发电效率低的问题,提出一种自动变桨距立轴风力机方案。根据叶素理论,建立了变桨距叶轮的功率模型,并获得若干种不同尖速比下的最优桨距角控制规律。基于多流管模型,计算得到了不同变桨距规律时的叶轮风能利用系数和转矩,结果表明:该自动变桨距规律可显著提高立轴风力机的启动性能和风能利用系数,为后续变桨距立轴风力机的开发奠定了研究基础。For solving the existing problems of poor starting performance and low efficiency of electricity generation on vertical-axis wind tubine, the automatic varible-pitch wind turbine was presented. According to blade element theory, the power of blade wheel was established and several control rules of blade pitch on different tip-speed ratio were obtained. Calculating power coefficient and Torque of blade wheel on different control rules based on stream- tube modle, the result which build a theoretical foundation for subsequent study and development show that these control rules of blade pitch can improve starting performance and increase power coefficient.
