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. understand all types of protection devices and their tasks in the power system

2. understand the basic principles of operation of electromechanical current, voltage and power relays

3. analyse and simulate by means of simulation software the performance of distance protection relays in high-voltage transmission lines

4. evaluate  features of digital relay protection for generators, transformers and transmission lines

5. create models of overcurrent and directional current relays in distribution networks with distributed generation and evaluate the features of their performance

6. simulate calculations by using state-of-the-art tools for coordination of overcurrent protection
