Contenus de l'unité d'enseignement

This course is the continuation of ELEC0014. It is devoted to computational methods for the analysis of electric power systems of any size in steady-state conditions, in the presence of faults, in balanced and unbalanced operating conditions, respectively. Emphasis is on "system" approaches initiated in the course ELEC0014. 
The covered material includes :

• synchronous machine: detailed Park model
• electromagnetic transients in the synchronous machine
• the power flow computation, numerical aspects, sensitivity analyses
• static security analysis: determination of post-disturbance operating points
• linear analysis based on nodal admittance matrix
• analysis of balanced faults, short-circuit currents
• analysis of unbalanced conditions: direct, negative and zero sequence components, three-phase analysis, case studies
• introduction to power system protections (by Cedric Moors from ELIA)

Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

At the end of the course, the student will understand and will be able to use computational methods pertaining to steady state operation and in the presence of faults. Those methods are typically implemented in power system analysis software used by industry, that the student will be able to use with discernment.
He/she will be familiar also with fundamentals of power system protections.

Savoirs et compétences prérequis

The material taught in course ELEC0014 must be known to start this course.
Basic knowledge and practice of MATLAB is also required.

Activités d'apprentissage prévues et méthodes d'enseignement

The theory is taught and exercises are solved without devoting separate time slots to these two activities. On the contrary, exercises are inserted in the theoretical course in order to illustrate or extend the latter. When solving the exercises, interaction with the students is solicited.
A substantial homework (project) has to be performed by groups of two students. It involves various questions relative to a power system with enough complexity, whose data are provided. Those questions cover a large part of the material of courses ELEC0014 and ELEC0029 . The ARTERE software is distributed to the students. Some questions require to develop scripts in MATLAB language.

Mode d'enseignement (présentiel ; enseignement à distance)

face-to-face.

Lectures recommandées ou obligatoires et notes de cours

For some sections, detailed lecture notes are available in French and can be downloaded from the Web page of the lecturer (see below). The student who does not understand French should contact the lecturer as soon as possible; he/she will be recommended specific chapters in one or two textbooks in English.
For the whole course, the slides presented during the lectures are available from the same Web page.

Modalités d'évaluation et critères

A few small homeworks during the course, to be shortly presented in front of the class.
A project by group of two students (outlined above).
Oral examination : some parts of the project report are presented shortly by the students. This is followed by discussions on the whole report.
For the second-chance examination, the project has to be performed by each student individually.

Stage(s)

Remarques organisationnelles

The course is taught during the second quadrimester, one half-day per week. Time will be left to perform the homework (project) in the last part of the quadrimester.
