摘　　要：针对低风速地区风资源评估及风力机功率预测问题,采用ZephIR Lidar测风塔测风系统实时监测风资源的方法,对呼和浩特市某地区进行风资源评估。利用MATLAB对测风数据进行拟合,验证ZephIR Lidar实时监测数据的有效性与准确性。在此基础上,计算某S翼型1.5 kW水平轴风力机的功率特性曲线,模拟其在16个风向的平均功率,并对该风力机进行功率测试。结果表明,ZephIR Lidar所测数据与测风塔测风系统监测数据的相关因子为0.92,表明ZephIR Lidar采集的数据是真实可靠的。ZephIR Lidar测风系统可有效地进行风资源实时评估与风力机功率预测,对风力机安装位置的选择具有指导意义。In view of wind resources assessment and power prediction of wind turbines in low wind speed area, the wind resource assessment is carried out in a certain area of Hohhot by means of real time measurement system of Zeph IR Lidar-Anemometer tower. The validity and accuracy of Zeph IR Lidar real-time monitoring data are verified by fitting the wind measurement data with MATLAB. On this basis, the power characteristic curve of a S airfoil 1.5 kW horizontal axis wind turbine is calculated, and simulated its average power in all directions, and carried out the power test of wind turbine. The results show that the correlation factor between Zeph IR Lidar and wind tower monitoring system is 0.92, verify the reliability of the collected data; the Zeph IR Lidar wind measurement system can effectively evaluate the wind resource and predict the power of the wind turbine, which is of guiding significance to the selection of the installation location of the wind turbine.
