Metrological Competence Center for Windenergy

The Competence Center for Windenergy of the Physikalisch-Technische Bundesanstalt provides a worldwide unique metrological infrastructure for high level calibrations of mechanical components for wind energy and wind lidar systems. The focus is on three measuring devices. First, a large coordinate measuring machine with a measuring volume of 5 m x 4 m x 2 m for drive train components, second, a wind tunnel for the calibration of mobile wind lidar systems, and third, a torque standard measuring machine for the calibration of torque transducers with a maximum load of 5MN m, which can be expanded to 20 MNm. The first part was completed with the inauguration of the Euler I building in February 2018. It functions as both, a large coordinate measuring machine and a wind tunnel. The standard torque measuring device is expected to be implemented in 2020 after finishing the Euler II building. The five-year project started in 2016. The cost of new buildings, measuring machines and developments is about 15 million €. The project is funded by the German Federal Ministry for Economic Affairs and Energy via the project's executing organization in Julich.
