| 摘 要： | 从降低风力机成本及提高风力机运行可靠性的角度，建立以最小的叶片质量获得最大的年发电量两个目标函数，以叶片体型参数及运行参数等关键参数为设计变量，以叶片的强度为主要约束条件的多目标优化设计数学模型，采用Pareto遗传算法对某1.5MW风力机叶片进行最优体型设计研究。与原设计叶片相比，最优体型设计方案提高了风力机的年发电量、减轻了叶片质量，说明优化设计模型合理有效。

| Abstract: | A mathematical model for the multi-objective optimization design is established for the purpose of reducing the cost and improving the operation reliability of a wind turbine. The model has two objectives?: the minimum blade mass and the maximum annual energy production. The key design parameters involve the geometric dimensions, structural and operation parameters while the demand of strength of the blade is employed as the main constraint condition. The optimization-shape design is carried out for a 1.5MW wind turbine blade by combing above objectives and constraint conditions with Pareto Genetic Algorithm. Compared with the original blade, the best shape design achieves an increase of annual energy production accompanied with a decrease of blade mass, therefore its effectiveness is verified. |
