An Investigation of Single Wind Turbine Wakes with Static LiDAR Wind Profilers

  title={An Investigation of Single Wind Turbine Wakes with Static LiDAR Wind Profilers},
  author={Rannveig Oftedal Eikill},
Three static LiDAR wind profilers were deployed during the seven month field experiment WINTWEX-W at ECN’s test site in Wieringermeer. The campaign was focused on capturing the structure and dynamics of the wake of a NORDEX N80 research wind turbine. The campaign has created a unique dataset for corresponding investigations. For this study also sonic anemometer and temperature difference measurement from a 108 m meteorological mast and SCADA data from the wind turbine have been used, in… 

Characterization of Turbulence in Wind Turbine Wakes under Different Stability Conditions from Static Doppler LiDAR Measurements

Results from LiDAR Doppler Beam Swing (DBS) measurements show wake peak frequencies consistent with sonic anemometer measurements, and Investigations on the effect of blade pitch on downstream wind speed and turbulence intensity profiles indicate the potential for the development of stability-dependent wind farm control strategies.



Field Measurements of Wind Turbine Wakes with Lidars

AbstractField measurements of the wake flow produced from a 2-MW Enercon E-70 wind turbine were performed using three scanning Doppler wind lidars. A GPS-based technique was used to determine the

Performance of a Wind-Profiling Lidar in the Region of Wind Turbine Rotor Disks

AbstractAs the wind energy sector continues to grow, so does the need for reliable vertical wind profiles in the assessment of wind resources and turbine performance. In situ instrumentation mounted

Volumetric scans of wind turbine wakes performed with three simultaneous wind LiDARs under different atmospheric stability regimes

Aerodynamic optimization of wind farm layout is a crucial task to reduce wake effects on downstream wind turbines, thus to maximize wind power harvesting. However, downstream evolution and recovery

Quantifying Wind Turbine Wake Characteristics from Scanning Remote Sensor Data

AbstractBecause of the dense arrays at most wind farms, the region of disturbed flow downstream of an individual turbine leads to reduced power production and increased structural loading for its

3D Volumetric Analysis of Wind Turbine Wake Properties in the Atmosphere Using High-Resolution Doppler Lidar

AbstractWind turbine wakes in the atmosphere are three-dimensional (3D) and time dependent. An important question is how best to measure atmospheric wake properties, both for characterizing these

Wind Flow Conditions in Offshore Wind Farms: Validation and Application of a CFD Wake Model

Abstract Since August 2009, the first German offshore wind farm ‘alpha ventus’ is operating close to the wind measurement platform FINO1. Within the research project RAVE-OWEA the wind flow

Characterization of the coastal marine atmospheric boundary layer (MABL) for wind energy applications

The main problem for the characterization of marine atmospheric boundary layer is the lack of available offshore measurements in relevant altitude range up to 200 m. Remote sensing meteorological

Wind-Turbine Wakes in a Convective Boundary Layer: A Wind-Tunnel Study

Thermal stability changes the properties of the turbulent atmospheric boundary layer, and in turn affects the behaviour of wind-turbine wakes. To better understand the effects of thermal stability on

Analysis of wake measurements from the ECN Wind Turbine Test Site Wieringermeer, EWTW

This paper describes an analysis of wake measurements from the research farm at the ECN Wind Turbine Test Site Wieringermeer. This research farm is owned and operated by the Energy Research Centre of
