Examination methods

Written and oral exam.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. analyse topology and operating conditions on transmission and distribution network lines

2. apply equivalent schemes of power system components, methods and principles of power system protection

3. categorise grounding systems of transmission and distribution networks

4. make a calculation of radial and double fed networks and more complex meshed networks

5. interpret load flow and short-circuit calculation in transmission and distribution networks

6. interpret system losses, reactive power compensation, transient states during short-circuit
