Research on inherent characteristics of the wind turbine tower based on field testing
The tested wind turbines in wind-power station of the Inner Mongolia Wulanyiligeng are situated in the average altitude for 1380mwith the southwest prevailing wind direction. There are 200 sets wind turbines installed there in the type of 1500KW/77. the hub height is 65m, diameter of the rotor is 77m, and rotating speed is 17.3 rmp. However, we choose model N53,N65 and N73, three of them as the tested wind turbines.
