The Faculty Board of Science and Technology
120 credits within science and/or technology, including Several Variable Calculus, Mechanics, Electromagnetism, Automatic Control and Fluid Mechanics. Solid Mechanics is recommended.
On completion of the course, the student should be able to:
judge qualitatively how the terrain influences the wind resource
calculate and analyse wind resource and energy production for a wind turbine from wind speed distribution, wind shear and power curve
by and large describe and motivate the design of typical wind turbines
explain the main differences between horizontal and vertical axis wind turbines regarding design and properties make some dimensioning calculations for wind turbines
describe typical control methods for wind turbines, as well as control problems
make a simple economical analysis of a wind turbine facility
give examples of rules (grid code) for connecting wind turbines to an electric grid
give an account of how wind turbines influence the environment and are influenced by the environment, as well as make some calculations related to environmental impact.

Lectures, lessons, laboratory work (1 credit), project work (1.5 credits) and study visit(s). The teaching is done in English.
Written exam with theoretical questions and calculation tasks (7.5 credits out of 10 credits). Laboratory course (1 credit out of 10 credits). Grade levels on the laboratory course: U, G (passed) Project work (1.5 credits out of 10 credits) Grade levels on the project work: U, G, VG (passed with distinction) To pass the course, it is also required that the laboratory course and the project work (oral presentation and written report, both in English) have been passed.
If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
