Wind power gradually becomes new important energy source. With the development of the wind power, it is well known that the vertical axis wind turbine has many advantages;for examples, it does not need to adjust the turbine with the direction of wind changing; so there need no the yaw device and pitch controlled device. As compared with the wind turbine, H-type vertical axis wind turbine has the advantages of more wind swept area, light weight, small inertia and simple structure. We test the torque of 1.5 kW H-type vertical axis wind turbines with different solidity and different structure under the condition of no wind by motor drive. We un derstand the effect of the different structure on vertical axis wind turbine by comparison with the test data. This paper gives a refer ence to the optimum design of the MW vertical axis wind turbine.%风能这种可再生能源正在成为新能源的重要力量.随着风电技术的快速发展,垂直轴风机无需对风,无变浆偏航装置,结构简单的优点逐渐被人们所认知.H型垂直轴风机具有扫风面积更大、质量轻、惯量小、结构简单等特点.实验对不同实度和支撑结构的1.5kWH型垂直轴风轮进行了无风条件下的电动拖动试验.通过对不同试验风轮空气阻力扭矩的测量和比较,初步了解了不同结构对H型垂直轴风机性能的影响,为今后兆瓦级垂直轴风机的设计提供了优化方向和参考依据.
