摘　　要：提出了直叶片垂直轴风力机风轮的优化设计模型,该模型以双向多流管理论为基础,考虑了风场风速的概率分布,以风力机年能量输出最大为设计目标,使用遗传算法进行搜索寻优。利用开发的优化设计程序,针对特定风场优化设计直叶片垂直轴风力机风轮,并与已有风力机相比,优化设计结果有明显的优越性,说明该优化设计模型的有效性和实用性。An optimization model for straight-bladed Darrieus-type vertical-axis wind turbine is presented in this paper. The model is based on multiple stream tubes theory and refers to the wind speed distribution function on the specific wind site with the objective to satisfy the maximum annual energy output, and genetic algorithm is used to carry on the search process. The wind turbine is designed by using the program developed with the optimization approach. Compared with the conventional method, the new design exhibits obvious advantages , which verifies the effectiveness and practicability of the optimization model.
