Objectives

This course aims to develop students’ skills on:
1. the acquisition and demonstration of advanced knowledge on the constitution and performance of protection and electrical energy systems (CDIO Syllabus: 1.2, 1.3, 1.4, 2.1, 2.3);
2. the treatment, validation and interpretation of results obtained in practical assignments, namely in the parameterization and programming of digital relays (CDIO Syllabus: 1.2, 1.3, 2.1, 2.3);
3. autonomous work and bibliography research (CDIO Syllabus: 2.4 and 3.3);
4. planning and developing a team work (CDIO Syllabus: 2.4 and 3.1);
5. report writing;
6. the understanding of external, enterprise and commercial contexts in which this sector is incorporated (CDIO Syllabus: 4.1 and 4.2);
7. setting objectives and project management (CDIO Syllabus: 4.3 and 4.6)

Eligibility for exams

Assessment components:
- class preparation;
- report about testing and relay programming;
- final exam

If there are not many students enrolled in the course, the final exam can be replaced by a highly demanding assignment, which will cover all the themes of the course. This assignment is to be done during the semester.

Students will be admitted to exams if they:
- do not exceed more classes than allowed;
- achieve a minimum mark of 50% in the preparation of classes;
- achieve a minimum mark of 50% in testing and relay programming assignment.

All these components assess CDIO Syllabus.

Calculation formula of final grade

Class preparation- 2 values
Theoretical-practical assignments, reports, practical tests and relay programming- 5 values
Final Exam- 13 values; Students have to reach a minimum mark of 8

Examinations or Special Assignments

Final exam, written report about testing and relay programming and class preparation

Special assessment (TE, DA, ...)

Exam.

Classification improvement

Students can meet professors between 8 am and 4 pm in their offices, as long as they are not giving a class.
Students can schedule a meeting by sending an e-mail.
