Abstract

the wind generator is gradually increased recently according to new status, so the dynamic and kinematic equation is needed to use to them as well. This paper will express the all kinds of these respect to adopt curve to explain the relation of them. It is observed that the speed is 30r/m and 16m/s under the wind speed of 15.8 m/s at 0° that becomes cosine distribution. The decreasing α and β is the way from 0 to 83° to increase them. When α increases from 83° to 180° the power and force increase too. With the increasing time to 1.4s the angle of attack increases steeply to 145° then the line becomes sluggish until more than 4s. It expresses that the first several time is significant to turbine blades’ turning rotation. There is a certain power changes in power with 200KW and force with 10KN with β changing from 0 to 20°. The acceleration at 15r/m is tow times larger than that at 7.5r/m. The power consumption and efficiency will be low. Only rotating speed reaching a certain value can the maximum effect be. The tip speed ratio Cp will be smaller below 10 when the v increases into 4m/s an then it shows a slow decreasing regardless of changing their radius.
