LiDAR Measurement

CUBE Engineering LiDAR Measurement

Measurement methods using LiDAR devices for conducting wind speed measurements have made enormous progress in recent years. Today, this technology represents a real alternative to performing wind measurements with measurement masts and anemometers.
The LiDAR measurement technology is based on the Doppler effect. Its operating principle is similar to that used in the speed measurements made with radar guns.

An overview of the advantages of LiDAR measurement

  • Usually no official authorizations (e.g. a building permit) are required. This saves time and money and makes it possible to start the measurement activities in a short time frame.
  • Making clearings in forested areas is not necessary. That means there is no restriction based on designated seasonal clearing periods. A minimal light radius of approximately 30 meters is required.
  • Measurements to a height of 200 meters are possible. Measurements can be made directly for various hub heights thus reducing uncertainties in the vertical wind profile.
  • Mobility - If a large wind farm is planned, LiDAR measurements may be taken at various points in the planned area. This does require a second reference measurement in the planned area.


CUBE's LiDAR services

We offer measurement strategies customized for your specific area in accordance with all applicable standards and guidelines (TR6 revision 9).
To take seasonal fluctuations into account, the measurement period should encompass a complete year if possible. For short-term measurements, we recommend a combined approach making use of a smaller measurement mast at 2/3 or less of the hub height or the inclusion of data from reference wind turbines in the site vicinity.
This will keep the level of uncertainty in the wind energy yield assessment to a minimum.
