Wind Measurement

Independent wind measurement is indispensable for a bankable revenue forecast. The secure database of WindGuard as a DAkkS-accredited testing laboratory facilitates the wind resource assessment and protects against long-term losses.

The anemometer calibration in WindGuard’s internationally recognised calibration wind tunnels ensures accurate measuring devices. Calibration of remote sensing systems, such as LIDAR or SODAR is also DakkS-accredited. Optimised wind measuring concepts, redundant design, and the experience of hundreds of projects from around the world support clean data collection.

WindGuard provides the optimal foundation for a successful wind farm project.

Remote Sensing Systems: LIDAR and SODAR

 

The remote sensing systems LIDAR and SODAR provide alternatives to the collection of data with wind measurement masts.

LIDAR stands for "LIght Detection And Ranging“, and refers to an optical wind measurement method. Laser beams are emitted, and wind speed and direction are calculated based on the scattering of the beams. The LIDAR system can measure at high altitudes and does not require planning permission.

SODAR stands for "SOnic Detecting And Ranging" and refers to a sound-based wind measurement method. These sound waves are emitted and wind speed and direction are calculated based on the backscattered signals.

WindGuard is a DAkkS-accredited calibration laboratory as per DIN EN ISO/IEC17025: 2005 for LIDAR and SODAR systems. The calibration is traceable to national standards. A WindGuard test field is also used for the classification of LIDAR and SODAR.

Our independent experts will advise you as to in which cases LIDAR and SODAR can provide accurate data for a reliable wind resource assessment.

 

Measurement and System Sales

 

Choose optimum solutions instead of conventional standards, with individually tailored measurement systems and cabinets from WindGuard. Our experts determine the necessary equipment and software, and ensure that all components work seamlessly together.

The system can, for example:

  • handle various measurement heights
  • optional charge 10-minute statistics apart of time series
  • work with all types of sensors, which can also record ice or precepitation
  • work with other and/or different interfaces (Apple, MS, etc.)
  • be programmed for operation in different languages
  • be linked to Web 2.0 for data presentation
  • combine several data acquisition systems due to modular design

Benefit from professional technology, in which practical knowledge of power curve measurement, prototype or resurvey measurements, and wind measurement continually contributes to WindGuard quality.
