| 摘 要： | 为降低风道式风力发电机的成本,提出了一种风力发电机迎风及调速方法。在风道装置始终正对风向的条件下,由于偏心机构和凸轮机构的共同作用,在风速低时,风轮正对着风向,在风速超限时,风轮相应侧偏,以限制风轮转速。基于空气动力学基本理论,推导出其结构参数的表达式,并叙述了各结构参数的选取原则。该方法可有效地起到大风限速的作用,提高风力发电机工作的稳定性。该调速机构结构简单、成本低,安装维护方便。

| Abstract: | In order to reduce the cost of duct-type wind generator,a method of wind facing and speed control was proposed.Under the condition that the duct device always faces the wind direction,through the joint function of eccentric device and cam gear,the wind turbine will face the wind direction in case the wind speed is lower,and the wind turbine should be deflected correspondingly in order to limit the rotary speed of the turbine in case the wind speed is over the limit.Based on aerodynamic principle,the express... |
