Objectives

The course aims to develop students’ interest in and knowledge and understanding of tools and methods for system stability, control and power system circuit interruption and switching over-voltages. The course addresses in depth stability and switching over-voltages.
Learning Outcomes:
Students will develop knowledge and understanding of:
- fundamental concepts, principles and mathematical theories used for stability problems
- fundamental concepts for the study of switching overvoltages.
They will acquire intellectual and practical skills to:
- develop appropriate models of scenario to study the stability problem
- develop appropriate models to study switching overvoltages.
(Skills CDIO- Conceiving — Designing — Implementing — Operating-1.2,1.4,2.3,2.5,3.2,3.3,4.2,4.3,4.4 e 4.6)

Teaching methods and learning activities

Lectures, discussion and interaction about concepts and foundations of the methodologies. Tutorial classes dedicated to the development of small group projects that constitute the assignments of the course.

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

Compliance with the rules in force attendance.
Completion of the assignments, with a minimum of 40%.

Calculation formula of final grade

Written exam, 80%
Assignments, 20%
(Minimum of 40% in both components)

Examinations or Special Assignments

During the realization of the practical part of the examination is not allowed to use calculators range of TI-Nspire (Texas Instruments). As a general rule, it is only allowed to use calculators which meet the following requirements:
- Have no ability to read pdf files or image format (including vector formats)
- Does not have the capacity of distance communication.

Special assessment (TE, DA, ...)

All the students must complete the assignments.

Classification improvement

A second opportunity for the exam is available.
Distributed evaluation  by its nature cannot be improved.

Observations

Students with frequency from previous years and that have performed the computational work may apply to the professor that the previous work be considered.
