摘要
针对垂直轴风力发电机自启动能力差和风能利用效率低的问题,提出了自动变桨控制策略,并搭建了H型垂直轴风力发电机实验平台。基于叶素理论对叶片进行分析,得出了叶尖速比λ<1情况下的变桨规律。将定桨距模型和自动变桨距模型进行对比,结果表明:采用自动变桨距方案可以有效的提高垂直轴风力机的自启动能力和风能利用效率。
The poor self-starting performance and the low efficiency of electricity generation have restricted the development of H-type vertical axis of wind turbine all the time. The automatic variable pitch scheme has been investigated to solve the above problems. In addition, experiments have been done on the H-type vertical axis of wind turbine. First, according to the theoretical analysis of blade element, the variable pitch laws when λ〉1 have been obtained. Second, the performances of variable pitch model and fixed pitch model are compared. The improved self-starting performance and system efficiency by using variable-pitch laws were validated by experimental results.
