Verification station runs at full speed: windtest grevenbroich and GWU-Umwelttechnik complete 150th LiDAR verification
Grevenbroich (renewablepress) - Close to the end of the year 2018, windtest grevenbroich gmbh (wtg) and GWU-Umwelttechnik GmbH (GWU) reached a further milestone. At its verification station for remote sensing devices, the companies successfully completed their 150th LiDAR verification.
Since 2014 wtg is operating a verification station for remote sensing devices (RSD) in cooperation with GWU. Now, the 150th LiDAR (Light Detection and Ranging) device was successfully verified, positioning the companies at the forefront of the German market with this service. Over the last five years, wtg has measured LiDAR and SoDAR (Sound Detecting and Ranging) devices for some 40 different customers. This means that the verification station has been running at full speed from the very first moment.
LiDAR measurements are today’s standard
LiDAR devices are increasingly used for measuring wind, as measurement campaigns using a RSD offer a considerably more cost-effective and flexible alternative to a wind measuring tower. Moreover, LiDAR devices can easily measure wind at heights of up to 200 m.
For reliable wind resource assessments in compliance with Technical Guideline TR6, the LiDAR device requires performance verification by an independent measurement service provider before and after every measurement (in accordance with IEC 61400-12-1, Edition 2). “Our independent verification certifies that the devices measure wind conditions as reliably as a wind measuring tower with anemometers and vanes,” confirms Liliana Del Angel Bulos, responsible at wtg for the verification station.
“LiDARs, both ground and nacelle based, are gaining widespread acceptance,” says Del Angel Bulos, who also coordinates the RSD expert group at MEASNET. MEASNET is an international network for harmonized and recognized measurements in wind energy. “LiDAR devices are becoming the standard measurement system both for site evaluations and for power curve measurements on onshore and offshore wind farms,” Del Angel Bulos says, explaining the increasing interest in LiDAR devices.
“Thanks to easy handling and fast field installation, the LiDAR systems, which can also be used in combination with the GWU LiDAR trailer with integrated independent power supply, provide many advantages over other wind profile measurement methods,” adds Christina Schleicher, Master of Science Meteorologist, who is primarily responsible for the verification of LiDAR systems at GWU.
