Delivery of a "Scanning long range Doppler wind lidar" Text automatically translated in your browsing language Automatically translated

ForWind – Centre for Wind Energy Research at the Institute of Physics of the University of Oldenburg intends to investigate, among other things, large-scale wind farm effects and lidar-based wind field reconstructions in the efzn research project ‘Reallabor 70 GW Offshore Wind’. A measurement campaign in the Trident offshore wind farm cluster with the ‘Amrumbank West’, ‘Kaskasi’ and ‘Nordsee Ost’ wind farms north of Helgoland serves as a data basis. Wind speeds are measured in particular with the remote sensing method Doppler Lidar. For the investigation of flow effects on the scale of the wind farm, high measuring ranges of clearly > 10 km of the lidar systems used are required. The scanner of the system must support the half space above the device as well as slightly negative elevation angles. The scanner must also allow fast scans of at least 5°/s. Furthermore, a small spatial resolution with short laser pulse lengths at a lower measuring range is desired. Since several lidar systems are used in the campaign, uniform software and data interfaces to existing lidar devices are necessary. The data interfaces are to be used to control the device as well as for fast data transmission. For logistical reasons, only compact WindLidar can be used at the planned locations on wind turbines.
