摘要
雷达测风作为一种新型的测风技术,目前被广泛应用于风电场风能资源测量。中国区域地形地貌复杂,气象条件多变,雷达测风在复杂山地应用,其准确性和可靠性需进一步验证。以重庆市典型低风速复杂山地风电场作为研究对象,开展多款雷达观测对比工作,研究不同类型雷达对风电场风能资源测量的适应性和准确性,结果表明,复杂山地受地形、地貌、多雨、多雾等因素影响,雷达设备有效数据完整率相比传统测风塔较低,因此在复杂山地地形下,雷达设备应与传统测风塔进行配合开展测风工作,声雷达设备在南方山地地形下适应性要优于激光雷达。
As a new type of wind measurement technology,radar wind measurement is widely used in wind energy resource measurement in wind farms.China's regional topography is complex,and the weather is volatile.Therefore,the accuracy and reliability of radar wind measurement in complex mountainous areas need to be further verified.Taking the typical low wind speed complex mountain wind farm in Chongqing as the study object,this paper studies the adaptability and accuracy of different types of radar for wind farm measurement through the comparison of multiple radar observations.The results show that the effective data integrity rate of radar equipment is lower than that of traditional wind tower under the influence of factors such as terrain,landform,rain and fog.Therefore,in complex mountainous terrain,radar equipment shall be combined with traditional wind towers to carry out wind measurement work.In addition,the adaptability of acoustic radar equipment in southern mountainous terrain is better than that of LIDAR.
