Available protective functions for synchronous generators. Other available protections for transmission lines and transformers. Busbar protection. Breaker-failure protection. Other protective functions for electric power systems and wide area protection systems.

Learning activities and methodology

-Lectures, sessions for solving doubts in reduced groups, individual tutorials and personal work of the student, oriented to the learning of theoretical knowledge (3 ECTS credits). -Analysis and solving of practical exercises in reduced groups, laboratory sessions, individual tutorials and personal work of the student, oriented to the obtaining of practical skills related to the contents of the subject (3 ECTS credits).

Assessment System

% end-of-term-examination 60
% of continuous assessment (assigments, laboratory, practicals...) 40

Calendar of Continuous assessment

Continuous assessment, based on 3 exams, with the same weighting factor for each exam. The result of this continuous assessment can be taken as the 100% of the final grade for this course.

-Final exam in regular call:
The final exam is optional for students. Students can take the final exam, if they want; in such case, the weighting factor of the final exam is 60% and the weighting factor of continuous assessment is 40%.

-Extraordinary call:
If the student followed the continuous assessment, the weighting factor of the final exam is 60% and the weighting factor of continuous assessment is 40%. If the student didn't follow the continuous assessment, the exam of extraordinary call has a 100% of value in the final mark.
