Lidar-based wake tracking for closed-loop wind farm control [PDF]
, 2017 This work presents two advancements towards closed-loop wake redirection of a wind turbine. First, a model-based wake-tracking approach is presented, which uses a nacelle-based lidar system facing downwind to obtain information about the wake. The method

A Comparison of Edge Detectors in the Framework of Wake Pattern Modeling for Wind Turbines
International Journal of Prognostics and Health Management, 2015 To monitor wind turbine health, wind farm operators can take advantage of the historical SCADA (supervisory control and data acquisition) data to generate the wake pattern beforehand for each wind turbine, and then decide in real time whether observed ...
