研究目的
Investigating the characteristics of wind turbine wakes under different atmospheric stability conditions using Doppler LiDAR measurements.
研究成果
The study demonstrates that Windcube v1 DBS measurements can qualitatively represent turbulence spectra of the atmospheric boundary layer, with wake peak frequencies consistent under stable conditions. The findings suggest the potential for developing stability-dependent wind farm control strategies to optimize performance and reduce loads.
研究不足
The study acknowledges the limitations of DBS measurements, including the assumption of homogeneous flow and the probe volume averaging effect, which may affect turbulence retrievals. The vertical wind component is not accurately represented due to the Windcube v1 measurement setup.
1:Experimental Design and Method Selection:
The study utilized Doppler Beam Swing (DBS) measurements from three Windcube v1 LiDARs and sonic anemometers to analyze wind turbine wakes. The methodology focused on spectral analysis of wake measurements to understand turbulence and wake dynamics.
2:Sample Selection and Data Sources:
Data were collected during the Wind Turbine Wake Experiment–Wieringermeer (WINTWEX-W) at ECN’s Wind Turbine Test Site Wieringermeer, involving measurements from three Windcube v1 LiDARs and sonic anemometers.
3:List of Experimental Equipment and Materials:
Equipment included three Leosphere Windcube v1 LiDARs, sonic anemometers, and a Nordex N80 wind turbine.
4:Experimental Procedures and Operational Workflow:
The LiDARs performed standard DBS measurements at various altitudes, with data processed to filter for independent wind vectors and to avoid cross-contamination effects. Spectral energy densities were calculated for analysis.
5:Data Analysis Methods:
Spectral energy densities were analyzed to understand wake characteristics under different stability conditions, with comparisons made between LiDAR and sonic anemometer measurements.
