# 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.

See course description in Danish
