摘　　要：本文主要致力于改进升力型垂直轴风力机的自启动问题,同时保持较高的风能利用率。常见的升力型垂直轴风力机启动方法主要是用阻力型叶片带动升力型叶片转动,但是升力型的叶轮启动后高速转动时,阻力型叶轮对升力型叶轮的旋转会产生干扰,降低整体风力机对风能的利用效率。本文研究了一种压气喷气式升阻组合型垂直轴风力机启动装置,同时对风力机的叶轮进行了优化,在改进垂直轴风力发电机叶轮自启动方式的同时提高了风能利用率。This paper mainly focuses on improving the self-starting performance of lift-type vertical axis wind turbine while maintaining a high wind energy utilization rate.The common starting method of a lift-type vertical axis wind turbine is mainly to drive the lift-type blades to rotate with drag-type blades.However,when the lift-type blade rotates at a high speed after starting,the drag-type blade will interfere with the rotation of the lift-type blade,which will reduce the overall wind turbine’s utilization efficiency of wind energy.In this paper,a kind of pneumatic jet lift-drag combined vertical axis wind turbine starting device is studied,and the blade of the wind turbine is optimized,which improves both the self-starting performance of lift-type vertical axis wind turbine and the utilization rate of wind energy.
