Teaching Methods

The course requires 120 hours of lessons.
1) Power Systems: 42 hours of lectures and 18 hours for classwork and exercises with the aid of power system software
2) Power electronics: 40 hours of lectures and 20 hours of laboratory work.

Both modules are in Italian.

Verification of learning

Power Systems
One or more assessment tests with theoretical and practical questions are done during the course. The participation to the test is allowed only to all students. Tests will be used by students for self-assessment; not sufficient results can be recovered at the final examination. Minimum grade (18/30) is given when the level reached is basic, maximum grade (30/30) when the results are outstanding and all abilities achieved. Final examination is in the form of oral examination for the assessment of the communication skills and technical knowledge on topics not covered during the previous tests. For students that decided not to participate to tests the final examination aims also at assessing the applying knowledge and understanding skills with specific written tests and exercises

Power Electronics
The assessment method includes:
a) Practical test with a final report on the laboratory activities.
b) An oral examination about all the topics covered during which we will evaluate all the specified learning objectives.
The pass both tests shall be sufficient. The final exam grade is determined as follows:
1) 20% from the evaluation of the practical test.
2) 80% from the evaluation of the oral test.
The rating is 18/30 granted when knowledge / skills of matter are at least elementary, the 30/30 rating with possible praise, because knowledge is excellent.

More Information

Power systems Lecture notes and slides are provided, as well as exercises and tests given in past years. Lectures are presented with the aid of PowerPoint slides and tablet visual projection. If a tablet is used, the lecture is delivered to students as pdf at the end. Free or educational software programs for power systems studies are also provided.
Workers can ask for on-line tests and exercises on specific topics with the aid of a tutor or the teacher; in this case, TEAMS will be the platform for communication.

Due to the pandemic, lectures will be on streaming with Adobe Acrobat and TEAMS, and faculty classrooms. Students must declare their choices before the beginning of the academic year. The choice of streaming lectures cannot be overridden.
