Tóm tắt

This study proposes a novel approach to explore the solution space of a wind turbine rotor design process. The goal is to offer to blade designers the possibility to select an optimal rotor for given market conditions, assessing trade-offs and alternatives in a matter of minutes. The design process consists of sequential aerodynamic-structural optimizations, where the two loops are linked via a blade-loading parameter that can be varied by the user. A design study is performed starting from the IEA Wind Task 37 land-based reference wind turbine. The solution space is characterized for rotor diameters in the range of 130?160 m, rated generator power values in the range of 3.0?6.0 MW, and tip-speed ratios in the range of 7.5?12.5. Results are discussed highlighting optimal design decisions and trade-offs.
