Adaptive rotor concepts for demand-based power supply (B02)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: from 2021 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 434502799

For OWTs with a rated power of > 20 MW, a less fluctuating and more demand-oriented feed-in of wind energy is gaining in importance. The extremely large rotors required for this purpose should deliver more power relatively speaking in low winds and switch to a power and load-reduced operating mode at higher wind speeds. This requires predictive operation management concepts to limit extreme and fatigue loads. In the subproject B02, wind tunnel experiments under turbulent inhomogeneous inflow will be used to aerodynamically characterize a rotor concept with a novel adaptive operating characteristic and to validate the model-predictive approach.
