Course description

Basic concepts related to electrical power system (EPS) and its events; faults and failures; basic requirements for protective systems; elements of EPS protective systems; criteria for protection acting; current value, current differential, current direction criteria, active power and reactive power criteria; impedance, voltage and criteria of frequency change; non-electrical criteria for protection acting (temperature, gas, light arch); transmission line protection; LV, MV and HV lines protection; lines protection in a star and radial network; MV lines protection in different neutral point earthling ways; protection and telemetry in MV networks; automatic reactivation; synchro check, transformer protection; transformer characteristics in protection point of view; protection of transformers with small, medium and large power; Bucholz protection; bus-bar protection; bus-bar protection with spare protection of another EPS element; proprietary bus-bar protection (for example differential protection); protection of other EPS elements; chokes protection; electric machines protection; EPS frequency breakdown protection; overvoltage protection; integrated functions of protection and control systems; terminal fields; testing and starting up; necessary activities, testing equipment, procedures; maintenance activities; EPS plant event analyses through protection acting.

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. describe and understand the basic demands and criteria for making protection devices work

2. analyse all types of short circuits in electrical networks

3. evaluate the analysis of fault currents based upon which parameterisation of protection devices is performed

4. create, choose and evaluate appropriate protection for each element of the power system according to current-voltage conditions on these network elements

5. create outage events in the power system through the operation of protective devices
