Objective
It is the general aim of the project to introduce the SODAR technique as a tool in the siting and monitoring process for wind turbines. The characterization of sites for large wind turbines in complex terrain and in coastal areas can be achieved by this remote sensing technique measuring wind profiles in the range 20 m to 150 m simultaneously. Acoustic sounding is based on the effect of sound scattering due to density fluctuations in the air. The measuring principle can be briefly described as follows. A short pulse narrow beam acoustic signal is emitted into the atmosphere. The propagating sound undergoes scattering from small scale inhomogeneities in the acoustic refractive index field, whereas a small fraction of the signal is scatterd back to the earth.
The deliverables of the project will be
- Modification of SODAR systems for site characterization for large wind turbines
- Results from SODAR wind speed measurements at different sites - Results from wake measurements at large wind turbines
SODAR is a remote acoustic sensing technique which can be used for wind speed profile and turbulence measurements. It is a mobile system which is much less cost intensive than high meteorological masts. SODAR is thought to be an appropriate method to yield valuable contributions in the field of wind energy research.
Acoustic sounding is based on the effect of sound scattering due to density fluctuations in the air. The measuring principle can be briefly described as follows. A short pulse narrow beamed acoustic signal is emitted into the atmosphere. The propagating sound undergoes scattering from small scale inhomogeneities in the acoustic refractive index field, whereas a small fraction of the signal is scatterd back to the earth. The wind velocity can be derived from the Doppler-frequency shift of the received signal. Wind speed measurements up to 150 m are of general importance in connection with site identification and characterization as well as to characterize the operating conditions of existing large wind turbines.
