Measurement procedures for characterization of wind turbine wakes with scanning Doppler wind LiDARs [PDF]
Advances in Science and Research, 2013 The wake flow produced from an Enercon E-70 wind turbine is investigated through three scanning Doppler wind LiDARs. One LiDAR is deployed upwind to characterize the incoming wind, while the other two LiDARs are located downstream to carry out wake ...

A Review on the Meandering of Wind Turbine Wakes [PDF]
Energies, 2019 Meandering describes the large-scale, low frequency motions of wind turbine wakes, which could determine wake recovery rates, impact the loads exerted on turbine structures, and play a critical role in the design and optimal control of wind farms. This paper presents a comprehensive review of previous work related to wake meandering. Emphasis is placed

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 ...

Simulation of wind turbine wake interaction using the vorticity transport model
, 2010 The aerodynamic interactions that can occur within a wind farm can result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

Asset Redeployability and Biodiversity Risk
Business Strategy and the Environment, EarlyView.ABSTRACT We examine how asset redeployability influences a firm's exposure to biodiversity risk. Our empirical analysis provides robust evidence that firms possessing greater levels of redeployable assets exhibit significantly lower biodiversity risk.

Determination of wind turbine far wake using actuator disk [PDF]
, 2014 The growth in size of wind turbines over the last years is significant. The rotor diameter becomes somehow comparable to atmospheric boundary layer at the land surface. In this case the assumption of uniform velocity of upcoming wind cannot be valid. The

Large eddy simulations of wind turbine wakes in typical complex topographies
Wind Energy, 2021 There is a need to clarify the coupling characteristics of terrain‐induced wind fields and wind turbine‐induced wake in wind farm micrositing. However, research investigating the effect of hill shape on this interaction is lacking.
