Description

Wind speed and wind direction data collected from an actual site were used to investigate the behavior of wind turbine wakes under real wind conditions. In the simulation, a twodimensional Porous-Disk model was used, and one-second data of wind turbines were utilized as boundary conditions for the calculation to replicate the wind turbine wakes in a real wind field. Although the calculated results showed time deviations from the observed results, they agreed very well when the deviations were corrected. In the actual wind field, the wake of the wind turbines changed significantly due to fluctuations in wind speed and direction, resulting in frequent switching of the time period during which the wakes affected the downstream wind turbines.
