RWE, one of the world’s leading renewable companies has confirmed the commencement of Power Performance Testing of their turbines at Galloper Offshore Wind Farm utilizing the Nacelle Based Lidar ‘ZX TM’ from ZX Lidars.
ZX TM allows the power curve of wind turbines to be measured and verified as a function of the Hub Height wind speed and replaces the need for using a meteorological mast and anemometry installation as described in the IEC61400-12-1:2017 (ed. 1/ed. 2).
Operational rotor equivalent power curves can also be measured with ZX TM’s unique 50 points around the full rotor swept area, particularly important for turbines with larger rotor diameters offshore and on sites with complex veer or shear profiles onshore.
In October 2020 Siemens Gamesa approved the use of the nacelle based Continuous Wave scanning Lidar ‘ZX TM’ from ZX Lidars for Power Performance Testing.
About ZX Lidars (formerly ZephIR Lidar)
ZX Lidars provides industry-leading wind lidar products, ZX 300, ZX 300M and ZX TM for wind energy and meteorological applications. These Lidars deliver accurate wind measurements in both onshore and offshore applications at measurement heights / ranges across the full swept area of the blades of modern wind turbines, and beyond. With more than 30 million hours of operation in the field and over 7000 deployments (and counting), ZX Lidars has pioneered the use of Lidar in the wind industry. The company is proud of the many world firsts it has achieved with customers including: upwind measurements from a turbine nacelle, turbine wake studies, offshore deployments of both fixed and floating wind lidar, an industry-accepted validation process, re-financing and re-powering of a wind farm, successful demonstration of measurement accuracy in a wind tunnel and total wind project financing from a lidar without need for a met mast.
