Course contents :
|
| This elective course is devoted to power system dynamics, control and stability. It is made up of the following two parts:
1. Modelling of the main components and their regulations
- dynamics of the synchronous machine
- dynamics of the induction machine
- power system modelling under the quasi-sinusoidal approximation, numerical methods for time-domain simulation
- turbines and speed governors
- excitation systems and voltage regulators
- fixed and variable series compensation (FACTS devices).
2. Stability analysis and improvement
- Small-signal angle stability
- transient (large disturbances) angle stability :
- short-term voltage stability
- long-term voltage stability.

|
Learning outcomes of the course :
|
| At the end of the course, the student will have acquired a deeper understanding of how power systems operate, more particularly the dynamic phenomena that can restrict their range of admissible operation. The presented material will obviously strengthen his/her perception of electrical networks as "large-scale systems".
The course gives an opportunity to study in some more detail the dynamics of a practical, relatively complex nonlinear system. It improves the ability to interpret results coming from the simulation of differential-algebraic models. It is also an opportunity to outline some of the controllers commonly used by industry. Hence, the course may prove useful in other disciplines than power system engineering.
Finally, the course offers an opportunity to present results of research works in the area of concern. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| Prerequisite.
The material covered by course ELEC0029 (Electric Power Systems Analysis and Operation) MUST be known before dealing with the more specialized material of this course.
Non-ULg students should have attended a course with contents similar to that of ELEC0029. |
|
Planned learning activities and teaching methods :
|
| Besides theoretical presentations by the lecturer, the student has to practice the material on small case studies.
For a large part, they involve time simulations, performed with RAMSES, a software developed at ULg. An educational version of RAMSES is distributed to the students. MATLAB is also used for some analyses.
Practical sessions are included in the lectures, during which the students are asked to answer some questions with the assistance of the lecturer. After the course, the students are asked to solve other, similar questions and provide a report with their answers. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| face-to-face |
|
Recommended or required readings :
|
| The slides used in the theoretical course can be downloaded from the Web page of the lecturer (see below). |
|
Assessment methods and criteria :
|
| The grade relates to the above mentioned personal work. There is no written or oral exam. |
|
Work placement(s) :
|
| |
|
Organizational remarks :
|
| The course may also include seminars given by external speakers, as well as presentations of research works.
It is usually taught during the first quadrimester, according to a schedule to be agreed with the students. |
