摘要
提出了风力机风轮叶片的优化设计模型,该模型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,设计了1.3 MW风力机的叶片.与已有风力机相比,设计结果显示了明显的优越性,从而说明了该优化设计模型的有效性和实用性.
An optimization model for rotor blades of horizontal axis wind turbines is presented in this paper, The model refers to the wind speed distribution function on the specific wind site with the objective to satisfy the maximum annual energy output, using genetic algorithm to carry on the search process. Based on the developed optimization program, the blades of a 1.3 MW wind turbine are designed. Compared with an existing 1.3 MW wind turbine, the design shows obvious advantages, which verifies effectivities and ftmctionalities of the optimization model.
