摘　　要：为了验证国内首批漂浮式雷达测风装置的相关性和可靠性,了解设备测风精度的真实水平,在福清兴化湾样机试验风场区域通过漂浮式雷达测风装置与岛屿固定式测风塔同步测风。利用3个月的实际测风数据,对比分析岛屿固定式测风塔测风数据和漂浮式雷达测风装置在10,70,90和110 m四个高程的风速和风向数据,验证2种设备测风数据的完整性、合理性和相关性,最终论证漂浮式雷达测风装置在风速和风向方面的可靠性。对比结果表明:漂浮式雷达测风装置数据合理,完整率达到90%以上,相关系数超过0.95,漂浮式雷达测风装置各高度风速、风向均满足风资源评估的要求。In order to verify the reliability and correlation of the first Fraunhofer IWES Buoys in China and to know their real level of wind-measuring accuracy,wind data are synchronously measured by using Fraunhofer IWES Buoys and Wind Tower fixed on an nearby island in the wind-testing field in the Fuqing Xinghua Bay.By using the wind data measured in three months,wind speed and direction collected by the Fraunhofer IWES Buoys and the fixed wind tower at an altitude of 10,70,90 and 110 m respectively are compared and analyzed.The completeness,reliability and correlation of the wind data measured by the two types of facilities are thus verified and the reliability of wind speed and direction of the Fraunhofer IWES buoys is finally demonstrated.It can be concluded that the wind data from the Fraunhofer IWES buoys are reasonable,with a data integrity being above 90%and a correlation coefficient being higher than 0.95,indicating that both the wind speed and the wind direction measured with the Fraunhofer IWES Buoys at targeted altitudes can meet the requirements of wind resource assessment.
