Summary of validation test done by The Centre for Renewable Energy Sources (C.R.E.S) in complex terrain test site

The present mast-lidar comparison campaign proved that SpiDAR’s technology is suited for complex terrain measurements, by providing very good results for the average wind speed and wind direction.

Period May 24th and June 30th, 2012

Within the framework of ECN project "Comparative Measurements SpiDAR™ wind LiDAR system" (project number 6.00492) ECN reviewed data from the SpiDAR wind LiDAR system and compared it to the data from meteorological masts (MM5) at the ECN Wind Turbine Test Site Wier-ingermeer (EWTW) in the Netherlands.

The use of elastic Lidars to measure wind velocity in the planetary boundary layer is one of the most advanced and investigated applications of elastic Lidars. Roughly speaking, the various methods to measure wind can be divided into two categories: Coherent detection and Direct detection.

GL Garrad Hassan reviewed wind speed and wind direction data correlated by mechanical anemometry mounted on 100m lattice tower and a beta-version SpiDAR within the framework of a validation test.

Experimental Alaiz Wind Farm - Cener

The measurements have been performed at Experimental Alaiz Wind Farm - Cener, near Pamplona, Spain. Based on the results of this report, the SpiDAR has shown excellent results in complex terrain up to 118m height.

The wind measurements were taken with a meteorological balloon mounted with 6 anemometers in the range of 50 to 300m and the SpiDAR wind LIDAR. The measurements have been performed at a flat terrain area in a period of 3 days. The results exhibit excellent comparison for all covered heights with 100% data availability
