摘要 研究了变桨型风力机叶片的气动性能计算、叶片设计载荷评估、叶片结构设计、风力机组成本评估及风电场运营模型,并将这些模块进行了整合,得到了度电成本的计算方法,同时提出了风场运营收益最大这一叶片设计目标。基于有针对性的叶片参数化描述,采用自适应模拟退火算法,分别以不同的目标优化设计了1.5MW变桨型的叶片。分析比较了度电成本及风场收益两个指标在平衡发电量和成本上的区别,认为在可以确定上网电价的情况下,以风场收益最大为目标设计叶片能为风电运营商带来更多的收益。 Blade aerodynamic performance calculation,blade design load evaluation,blade structure design,system cost evaluation and wind farm operation model for variable-pitch wind turbines are investigated and then integrated.As a result,the analysis method for the cost of energy(COE) is derived,and a new target of wind farm profit(WFP) for wind turbine blade design is developed.Based on the shape parameterization,a 1.5 MW blade for pitch regulated wind turbine is designed with different objectives using the adaptive simulated annealing algorithm(ASAA).The difference between the COE and WFP is analyzed.Results show that with grid rate,blade design with the target of the maximum WFP it is more reasonable than that with COE.
