摘　　要：使用测风设备采集到的风速风向数据,通过滑动平均的方法,避免复杂多变的风况带来预测功率的剧烈波动;对风速-功率点进行修正拟合,并收集风机真实出力的点位对功率曲线进行迭代修正;以风力发电机相关桨角参数作为分类条件,提出了一种功率预测方法,实现在山地风场复杂多变风况下的精准风功率预测。通过仿真,验证了该预测方法的有效性,可供实际工程参考应用。By using the wind speed and direction data collected by the wind measuring equipment,the sliding average scheme can avoid the violent fluctuation of the predicted power caused by the complex and changeable wind conditions.The wind speed-power point was corrected and fitted,and the real output point of the wind turbine was collected to iteratively correct the power curve.A power prediction method is proposed based on the blade Angle,which realizes accurate wind power prediction for mountainous wind farm under complex and variable wind conditions.Through simulation,the validity of the proposed method is verified,and it can be used as a reference for practical engineering.
