Abstract:
Based on the data from 27 meteorological observing towers over South China for one year, it is found that the average wind power density index is less than the threefold wind speed index. The variation law between annual mean wind and shape parameter with height and a new method for estimating the average wind energy density at different heights are discussed. The results show that the average relative error of this method is 96%, which provides references for computing the wind power density so to estimate the variation of wind energy with height for the stations without gradient wind observation.
