Comparison of Measured and Simulated Turbine Response to Cold Pool Events

Kurzfassung

Certain weather conditions, such as cold pool events, lead to rapidly changing wind speeds and directions. In the WiValdi research wind farm, cold pool events were observed. Measured data of multiple physical quantities are available. To predict loads and power output during upcoming cold pool events, aeroelastic simulations will be used at the German Aerospace Center in the future. The input to these simulations should be generated from a meteorological forecast, which is still under development. Therefore, the measured wind conditions are used in place of the forecast in this study.

This study contributes to the preparation of such a forecast of loads and power. For high usability, the forecast must match reality in both the time domain and spectral characteristics. The results depend significantly on the wind input to the simulation, which is the focus of this article. Various wind fields representing cold pool events are generated from measured wind data and used in aeroelastic simulations. The simulated turbine response is compared to measurement data.
