Objectives

1. To transmit knowledge and develop students’ skills in the domain of High-Voltage Systems (CDIO Syllabus 1.3);
2. To prepare students to correctly use High-Voltage Systems and carry out studies and tests at High-Voltage Laboratories (CDIO Syllabus 2.1, 2.2, 2.3, 3.1, 4.1);
3. To develop projects of insulation coordination on SEE (CDIO Syllabus 3.3; 4.2; 4.5);
4. To inform students about the importance of numerical simulation and laboratory tests (CDIO Syllabus 3.3, 4.2 and 4.5).

Teaching methods and learning activities

Theoretical classes will be based on the presentation of the themes of the course unit. Students will be asked to participate in class.
Theoretical-practical classes will be based on problem solving. Exercises will be beforehand provided. Students will also be asked to participate in class.
Computer simulation of some transient phenomena will also be covered.
Students will participate in laboratory activities and they will be asked to write a critical report.

Software

Eligibility for exams

According to General Evaluation Rules of FEUP, students are admitted to exams, if they write their reports and do not miss more theoretical-practical classes than allowed by the rules (25% of the classes).
A visit to a laboratory of industrial dimension will take place, which is important in students’ training. Students will also be asked to write a critical report about it.

Calculation formula of final grade

Final Grade will be based on the average grade of the continuous assessment (8 values) and the final exam (12 values). Students have to reach a minimum grade of 40% in each of the components.

Continuous assessment comprises three components: 4 values (assignment using PSCAD/EMTDC), 2 values (laboratory assignment) and 2 values (a monograph about the state of the art about a theme of the course unit.

Examinations or Special Assignments

Students have to do 3 mandatory assignments (simulation, laboratory and monograph about the state of the art). Students may have to do extra assignments which can improve their marks.

Special assessment (TE, DA, ...)

According to General Evaluation Rules of FEUP. Continuous assessment component is mandatory to be admitted to exams.

Classification improvement

A final exam as above mentioned. However, it may be an oral exam.

Observations

Any other situations not mentioned here will follow General Evaluation Rules of FEUP and, if necessary, this course director can be contacted.
