Lidar Measurement

LiDAR measurement is an established method for determining wind potential.

LiDAR uses the so-called Doppler effect. Light pulses emitted by a laser beam are reflected by the smallest particles (aerosols) and recaptured by the measuring device. From the transit time of the light pulse and the frequency change, the so-called Doppler shift, wind speed and direction can be calculated.

LiDAR devices are compact and reliable. This makes it possible to measure wind speed, wind direction, turbulence and vertical wind profile even in terrain that is difficult to access. Compared to mast measurements, they offer many advantages, especially at today’s hub heights:

• Building permit not required
• Fast installation
• For forest sites, only small clearing required for installation
• High-quality measurement results even over 200 m height

LiDAR measurements are a recognized method according to FGW guideline TR 6 as well as IEC 61400-12-1 and can be used for many purposes:

• Stand-alone wind measurements
• Supplementary measurements
• Height profile determination
• Short-term measurements for assessment
• Additional measurement for power curve characteristics
• Performance optimization of individual plants and parks

Our LiDAR measurements are accredited according to DIN EN ISO/IEC 17025:2018.
