Please note! Course description is confirmed for two academic years (1.8.2018-31.7.2020), which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


Upon successful completion of the course, the student will:
1. understand the basics of transmission systems, distribution networks, power system components, electrical safety and high voltage engineering,
2. understand the principles of power and voltage control in the power systems,
3. be able to model power system components,
4. understand the technical limitations and rating factors of both the power system and its components,
5. have a basic understanding of protection and electrical safety.
