Statistical analysis of a field database to study stability effects on wind turbine wake properties

Abstract

Within the frame of the French project ANR SMARTEOLE, a 7-month measurement campaign had been set-up in the north of France to study the wake behaviour of 2 wind turbines, with a set-up using scanning LiDAR scenarii that captured the wakes of 2 wind turbines for different degrees of interactions. An extensive statistical study of the wakes behaviour under neutral atmospheric stability conditions has been already performed. The present study focuses on the effects of other stability conditions on the wake developments and on the meandering process.
