Long range off-shore wind assessment by high power scanning Lidars

摘要

A specific and world-premiere set-up for evaluating the potential of long-range scanning Doppler Lidar to serve wind energy applications has been organized by the CarbonTrust (UK) in the Dublin bay, Ireland. In this experiment the scanning Lidars are located on the Dublin bay shore and measure over the sea. Leosphere has deployed 2 scanning Lidars: the standard WINDCUBE 400S product and a prototype that is designed to considerably increase the measurement range. Additionally 3 vertical profiler WINDCUBE Lidars are located at ranges from 6 to 14km from the scanning Lidars, offering the possibility to wind speed measurement accuracy comparison. In this paper we propose to show the different Lidars performances in term of measurement ranges and wind speed accuracy, and analyze the specific atmospheric conditions that contributes to the different performances between the standard product and the prototype scanning Lidar.
