PO074: Performance and Value of a Zx LiDAR in predominantly stable atmospheric desert site conditions with a comparison against co-located met mast and Fulcrum3D SoDAR
Sasikumar Duraisamy, Wind Resource Manager, Intercontinental Energy
Abstract
As wind energy development accelerates worldwide, more campaigns are using SoDARs and LiDARs in addition to met masts. Lidar backscatter quality depends on the presence of aerosols, whereas SoDAR's functionality relies on the presence of thermal turbulence; however, local atmospheric conditions impact remote sensing devices, particularly in coastal desert conditions. The WGEH site in Australia has clean air (low aerosols), high temperature, shear and temperature inversion, low turbulence, and some isolated dusty conditions. Currently, there are 4 met masts (160m height), 10 SoDARs (Fulcrum3D), and 1 LiDAR (Zx LiDAR with continuous wave technology) at the site measuring at different locations. The LiDAR and One SoDAR units have been co-located with one of the met masts for study purposes. The following outcomes are expected from the comparative study with concurrent SoDAR and LiDAR data compared against the met mast. • Wind Speed validation of remote sensing devices against the met mast • Data availability review of Zx LiDAR at heights above met mast (>160m considering the WGEH site) • Turbulence profile comparison between Zx LiDAR and met mast • Shear profile comparison at rotor tip height (~250m to 280m), hub height (~150m), and rotor bottom height (~40m to 50m) to better understand the atmospheric stability based on the LiDAR measurement • Stable atmospheric conditions classification based on Vortex mesoscale supported with met mast temperature measurement • Influence of atmospheric stability on wind shear, wind veer, and turbulence above hub height measurement • Relationship between hub height wind speed and rotor equivalent wind speed This study helps understand LiDAR and SoDAR's performance at the site, in comparison with the concurrent mast measurement period and guides decisions on selecting the most accurate remote sensing devices for further expansion in the project. The study also helps to understand better various atmospheric problems that we currently experience above the met mast measurement height.
