The traditional way to carry out wind resource measurements is to install a met mast at the site of wind farms and at the height of the planned wind turbines. The met mast is equipped with calibrated anemometers and wind vanes at each specific measuring heights. Nowadays, the remote sensing lidars act as the alternative wind measurement mast. Especially for offshore use, they offer cheaper alternatives which require low-maintenance and require little space. LEICE’s experience ranges from ground-based systems to scanning lidars. Both systems can measure at high altitudes and do not require planning permission.

(1) Small size, low consumption, high accuracy, IEC 61400- 12- 1:2017 compliant;
(2) Continuous measurement of wind profile at 30 height gates from 20m to 350m;
(3) Suitable for wind resource survey and assessment, turbine power curve test, wind power prediction, wind shear analysis of complex terrain, atmospheric boundary layer dynamics research and other fields.
(4) Typical Data: Sec and time average wind speed/direction, vertical speed, max. and min. horizontal wind speed, turbulence intensity, turbulence dissipation rate, wind shear index.

Is Lidar an Alternative to Traditional Wind Measurement Mast?

LIDAR technology is a promising alternative for the measurement of winds, requiring less maintenance and lower costs than meteorological towers. They are capable of remotely profiling winds by means of an infrared laser, which is backscattered by aerosols and particles carried by the air. With more and more verification campaigns have been done, the industry is getting to accept profiling LiDARs to replace wind measurement mast for wind energy applications.
