The method of wind facing and speed control for duct-type wind generator
摘要
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 expression of structure parameters was deduced, the rules for various parameters determination was also proposed. This method could effectively limit the speed in strong wind condition, and could improve the stability of wind generator. The speed regulating device has the advantages of simple structure, low cost and easily installation and maintenance.关键词
