摘　　要：为提高风力机的风能利用系数,并为垂直轴风力机优化设计提供方法,提出一种针对垂直轴风力发电机气动性能提升的结构改进方案,即在2台转向相反的H型垂直轴风力发电机的上游区域放置一块挡流板,研究挡流板各参数对2台垂直轴风力发电机能量获取的影响,结果表明：挡流板宽度对风能的获取影响最敏感,而挡流板到两台风力机轴之间的距离以及大于风轮高度的挡流板高度对垂直轴风力发电机风能的获取始终为正面影响,选择合适导流板参数下的最大风能利用系数为0.45,与无挡流板时相比提升了36%。In order to improve the utilization rate of wind power,and to optimize the design of vertical axis wind turbines,puts forward a structure improvement scheme of vertical axis wind turbine about aerodynamic performance,namelyplacing and eflector on upstream area of two counter-rotating straight-bladed vertical-axis wind turbines（VAWTs）.Theparameters of deflector is studied in two vertical axis wind turbine energy obtained,the results showed that the width ofdeflector is most sensitive to obtaining wind energy,the distance between the two turbine shaft and the deflector on windpower obtained is always positive,and so is deflector height which is greater than blade height.Choosing appropriateparameters of the deflector,the maximum wind energy utilization ratio is 0.45,which is increased by 36%.
