On the use of Radar Wind Profiler Data for Wind Farm Site Selection: Hands-On with Degreane Horizon PCL-1300
Résumé
The first step in managing a wind energy project is wind assessment. Despite of ever more precise
meteorological models at macro- and mesoscales, precise on-sites measurements have to be realized
to ensure the economic viability of the farm. This mesoscale study shall be completed by a
microscale validation campaign to choose each turbine’s position (‘micrositing’) and yet maximize
energy output.
On-site assessment consists in measurements that lead to validate wind atlases data and, above all,
to take into account of small-scale variabilities. Generally, classical weather instruments are used:
anemometers, thermometers and barometers mounted on masts or tall towers. Lidar are becoming
popular.
Even though wind radar profilers are widely used for meteorological purposes, wind energy
applications are in their early stages, In this paper, we demonstrate the use of a L-band wind radar
profiler system to evaluate the wind energy potential at mesoscale. After introducing this system,
generic methodology is presented. Pros and cons between classical instruments are evaluated.
Further improvements are discussed.
