Abstract:
At the Zhangjiakou Zhangbei National Fengguang Storage Test Site, by means of the Windcube laser radar system and a wind tower to observe the test data simultaneously and calculate a variety of statistic data, a comparative analysis is made of wind speed, wind direction, standard deviation, and turbulence intensity. The results show that: the data efficiency of Windcube reached 97% under 140 m, and the results are basically unaffected by rainfall; the correlation coefficients of wind speed and wind direction tested by Windcube and wind tower data are up to more than 99%. The average deviation of wind speed at 100 m is -0197 m/s; the relative deviation is -23%; the average deviation of wind direction is -62°; and the average deviation of turbulence intensity is 0009, which are consistent with results of other literature, meets the requirements of wind energy resource assessment.
