Goal:The goal of the course is to educate students about relay protective devices as well as the concepts of power system protection. Students learn about protective devices and protection systems of overhead and cable lines, transformers, generators, motors, and buses. The goal is to learn operating principles of relay protection and to design and maintenance protective systems.
Outcome:After exam passed, students should be able to select and sett relay protective devices. Also, they should be familiar with the design and concepts of substation protection.
Contents of the course
Introductory part: the role of the relay protection. Protective relay devices. Basic requirements.
Protective relays: vercurrent, overvoltage, and directional protection.
Protective relays: distance protection, over- and underfrequency protection.
Numerical examples which alleveate understanding of practical setting of relays are realized in the lecture room. Several computer simulation exercises which demonstrate selection and setting of the relay protection are realized in the laboratory using Alternative Transients Program (ATP) software tool.
