Abstract:

Studying wind turbine wakes is essential for optimizing wind turbine arrangement within wind farms. Pulsed coherent Doppler lidars (PCDLs) are the most effective tools for such studies. This paper suggests a new method for three-dimensional visualization of wind speed within a wake based on PCDL measurements. Numerical simulation shows that this method enables wind speed deficit estimates with a relative error of no more than 4%. An atmospheric experiment with the use of this three-dimensional visualization method reveals that the wake cross section exhibits a wind speed deficit structure close to an annular distribution, consistent with numerical simulation with the use of LES and RANS methods.
