在张家口市张北县国家风光储输试验场,采用Windcube激光雷达测风系统与测风塔测风设备同步观测试验数据,计算了各种统计量,对风速、风向、标准偏差和湍流强度进行了对比分析.结果表明:Windcube测量数据有效率在140 m以下达到97％以上,测量结果基本不受降水影响；Windcube与测风塔测得的风速、风向相关系数均达到了0.99以上,100 m高度风速偏差为-0.197 m/s,相对偏差为-2.3％,平均风向偏差为-6.2°,平均湍流强度偏差0.0093,与其他文献的对比分析结果一致,能够满足风能资源评估的要求.%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 -0. 197 m/s; the relative deviation is -2. 3% ; the average deviation of wind direction is - 6.2°; and the average deviation of turbulence intensity is 0.009, which are consistent with results of other literature, meets the requirements of wind energy resource assessment.
