摘　　要：对三维偏航全尾流模型进行了改进,考虑偏航风力机尾流的动态时延特性并进一步考虑其对尾流场空间分布的影响,提出一种风力机偏航三维动态全尾流模型,即Y-3DJGF-T模型。在某陆上风电场使用2台垂直式激光雷达进行现场实验,并结合数据采集与监视控制(SCADA)系统数据分析了偏航状态下尾流延迟时间及速度变化,以验证Y-3DJGF-T模型在尾流中心线和垂直剖面风速的预测准确性。结果表明:Y-3DJGF-T模型计算值与实测值的平均相对误差为2.51%。The three-dimensional yaw entire wake model was improved,and a three-dimensional dynamic entire wake model of wind turbine yaw,namely the Y-3DJGF-T model,was proposed,considering the dynamic delay characteristics of the yaw wind turbine wake and further considering its influence on the spatial distribution of the wake field.To verify the accuracy of the Y-3DJGF-T model in wake centerline and vertical profile,two vertical lidars were used to conduct field experiments,and the data acquisition and supervisory control(SCADA)system data were used to analyze the wake delay time and velocity changes under yaw conditions.Results show that the average relative error between the calculated and measured values of the Y-3DJGF-T model is 2.51%.
