风力机桨叶总体优化设计的复合形法

WINDTURBINE BLADE GLOBAL OPTIMUM DESIGN USING COMPLEX METHOD

提出了以年能量输出最大为优化目标 ,使用复合形法搜索最优点的风力机桨叶总体优化设计模型。根据南澳风电场风速分布函数 ,使用该模型设计了 6 0 0kW风力机。对比总体优化设计结果和引进的NM6 0 0kW风力机的实际数据 ,分析了设计结果的合理性 ;对比Wilson方法的设计结果 。

This paper presents a global optimum design method for Horizontal Axis Wind Turbines (HAWT). The method refers to the wind speed distribution function on the specific wind site,with the objective to satisfy the maximum annual energy output,using complex method to carry on the global optimum searching.Using this method,a 600kW HAWT is de signed with the wind speed distribution function on the Nan'ao wind site.The design results are compared with the origi nal data of NM600kW HAWT to show the rationality.The comparison between the results of the Wilson method and the global optimum design method shows the advantage of the latter.
