Abstract: 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%.
