| 摘 要： | 基于风速分布服从Weibull双参数分布,分析变速恒频风力机的特点和运行特性,以1.5 MW变速恒频风电机为研究对象,构建风电机在特定风资源下年能量输出的优化模型,以尽可能实现年能量输出最大化为优化目标,将改进型粒子群算法用于模型进行求解,并与原设计的风电机参数相比,求解结果显示其优越性,从而说明该方法的可行性和实用性.同时,探讨了分别改变Weibull分布尺度参数和形状参数时,叶尖速比与能量输出的关系；仿真结果表明风能大小更多的由Weibull分布的尺度参数决定,说明了与风速分布相比风能大小更多的取决于平均风速.

| Abstract: | Based on the fact that wind speed follows a Weibull two-parameter distribution,the features and operating characteristics of the VSCF wind turbine were analyzed.Uses 1.5 MW VSCF wind turbine as the research object,the annual energy output optimization model for wind turbine in the specific wind resource was formulated.The optimization goal was to maximize the annual energy output as much as possible,to solve this model a modified particle swarm optimization algorithm was proposed.In comparison with the orig... |
