Turbine Wake Deflection Measurement in a Wind Tunnel with a Lidar WindScanner

Journal of Physics: Conference Series, 2020
Abstract Wind turbines are typically closely spaced in wind farms, and thus operate in the wake of upstream turbines and experience power losses. Currently, one of the techniques to reduce the wake interaction between turbines within a wind farm is to yaw the upstream turbine with regards to the incident wind direction.

Improving the wake steering engineering models with wake deflection coupling effects

, 2019
In the presentation, we propose engineering model extensions to take into account the coupling between yaw offset and deflection of the wake for the downstream and the neighbouring wind turbines.

Offshore Wind Farm Wake Deflection Control Based on Adaptive Wind Condition Prediction Error

Zhongguo dianli
Wind farm wake deflection control is an important tool to reduce the wake effect and improve the total power generation. The wind prediction is an important input to the wind farm wake deflection control, and its error has a huge impact on the actual ...

Wind tunnel experiments on wind turbine wakes in yaw: effects of inflow turbulence and shear [PDF]

Wind Energy Science, 2018
The wake characteristics behind a yawed model wind turbine exposed to different customized inflow conditions are investigated. Laser Doppler anemometry is used to measure the wake flow in two planes at x∕D  =  3 and x∕D  =  6, while the turbine yaw ...
