In partnership with General Electric (GE) , researchers at Sandia National Laboratories (Sandia) and the National Renewable Energy Laboratory (NREL) successfully installed and deployed a device called a spinner lidar on the hub—the structure that connects blades to the main shaft—of a 2.8-megawatt GE wind turbine in Lubbock, Texas. The spinner lidar, which uses a rotating laser to provide highly accurate wind speed data, was deployed as part of the Rotor Aerodynamics, Aeroelastics, and Wake (RAAW) experiment. The researchers obtained the spinner lidar instrument from the Technical University of Denmark and designed and fabricated the custom mounting frame and accompanying hardware. https://t.cn/A6HqtP3i
