Learning outcomes
The aim of the course is to give a general overview about wind energy systems. The working principle of such systems will be introduced as well as the theoretical knowledged required to design the plant. Norms and regulations will be also presented. Finally, the economy of building and running the plants is studied.
Course contents
• Introduction: history of wind energy, modern wind turbines, anatomy of a wind turbine, HAWT and VAHW, power coefficient
• Airfoils and general concept of aerodynamic: general overview, aerodynamic forces and coefficients, Buckingham's theorem, Reynolds and Mach numbers, airfoils, lift and drag.
• Aerodynamic of wind turbines: one-dimensional momentum theory, Betz limit, wake rotation, blade element momentum theory, blade shape for ideal rotor, aerodynamic of VAWT.
• Wind characteristics and resources.
• Wind turbine control: introduction and motivation, overview of wind turbine control systems, active and passive control system, yaw control.
• Wind turbine design and testing: sources of loading, ultimate and fatigue loads, design loads, international standards, modern wind turbine design procedure.
