Wind Turbine Design - NREL
Technische Universit t M nchen Wind Energy Institute Wind Turbine Design Origins of Systems Engineering and MDAO for Wind Energy Applications Carlo L. Bottasso Technische Universit t M nchen, Germany WESE Workshop, Pamplona, Spain, 2-3 October 2019 Design Optimization of Wind Turbines Outline Some technical reasons behind the falling prices of energy from wind Multidisciplinarity and the need for MDAO MDAO tools: architectures, methods, limits and gaps Conclusions and outlook Design Optimization of Wind Turbines Design Trends Higher tower higher wind speed because of vertical shear Larger swept area larger power capture Improved capacity factor lower CoE Reducing specific power, size grows more than power rating (Source: IEA Wind TCP Task 26) Data for onshore turbines 1MW
Aero Optimum ≠ Structural Optimum Example: INNWIND.EU 10 MW (class 1A, D=178.3, H=119m) ... Blade and tower beam models Structural design parameters Aeroservoelastic multibody model Aerodynamic design parameters Constraints: ... • Cooling • Pitch • Brake ...
