Single-Course English 10 ECTS

Wind Turbine Technology and Aerodynamics

Overall Course Objectives

To give a general introduction to the aerodynamics and elastic behaviour of a modern wind turbine. Further, the placement of wind turbines is addressed. Also, the elastic blade response with the aerodynamic loads is addressed.
In addition, students will learn basics of Electrical Power Engineering including circuit theory, introduction to relevant components (generators, transformers, cables…) and wind electric energy system. Economical as well as political issues related to wind energy will be introduced.

Learning Objectives

  • Define airfoil data
  • Compute induced velocities
  • Develop a computer code to calculate aerodynamic loads
  • Calculate internal loads and the static deformation of a loaded wind turbine blade
  • Compute the eigenmodes and associated eigenfrequencies for a wind turbine blade
  • Draw velocity triangle incl. induced velocities
  • Determine annual energy production for a wind turbine
  • Understand and be able to solve electric DC and AC circuits using Ohm’s and Kirchhoff’s laws
  • Understand and be able to quantify the relevant component’s operation with equivalent circuits
  • Understand and be able to quantify the components interaction as a part of the system in modern wind energy
  • Calculate active and reactive power in AC circuits
  • Calculate loads and energy production for a vertical axis wind turbine
