摘要
垂直轴风力机中升力型风机效率高但一般不能自启动,阻力型风机效率低但易启动。根据两种不同类型的垂直轴风力机各自的特点,采用超越离合器作为连接件,设计制作了一种由Darrieus风力机和Savonius风力机组成的组合式风机模型。在对有无加装S型风机进行了启动风速、输出功率的性能对比后发现,加装S型后的启动风速更低,而输出功率则差别不大。
In vertical axis wind turbine （VAWT）, lift type has high efficiency but starts difficultly at low wind speed; resistance type has low efficiency but starts easily at low wind speed. Based on the advantages of two types, a new-type self-starting vertical axis wind turbine was designed by using overrunning clutch as the connection unit. It contained a Darrieus wind turbine and a Savonius wind turbine. By comparing the output power and starting velocity with or without S-type wind turbine, it indicates that with S-type wind turbine the starting velocity is lower and the output power is almost equal.
