WINSENTvalid

Interventionsstudie mit in situ Turbulenzdaten aus UAS Messungen im Bereich des Testfeldes

01/02/2023 to 31/07/2025

With the operation of the research test site WINSENT including its extensive measurement equipment, an important contribution is made to cover the existing research and development demand for wind energy sites in mountainous complex terrain. The test site is unique due to its location directly behind a steep, forested terrain edge (Albtrauf) and its extensive equipment including the research wind turbines (FWEA). In the project 'WINSENTvalid' the numerical models, which were developed in the previous project WINSENT, will be validated with the help of measurement data. The site offers an excellent opportunity to investigate the turbulent overflow of the seasonally variable slope and the installations adjoining it to the east on the Alb, and thus an almost ideal environment for researching the dynamic behavior of WT (wind turbines) in complex terrain, in particular the interaction with the lower troposphere or the atmospheric boundary layer (ABL). In WINSENTvalid, three additional IOP (intensive operation periods) will now be conducted after the FWEA have been erected in order to quantify the influence of the FWEA on the flow conditions in the complex terrain and to reduce uncertainties in the model chain. In the IOP, all available measurement systems will be used synchronously to generate a comprehensive database for flow physical analyses and validations of the numerical models. Certain flow situations are simulated with the numerical model chain and compared with the collected measurement data. The subproject of the University of Tübingen (EKUT) contributes in situ measurements at the test site, which are obtained with small, uncrewed operating research aircraft (UAS). The UAS can be deployed in the incoming flow, on the slope, above and also behind the test site and resolve turbulent fluctuations down to the sub-meter range.
