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, associated per unit systems
- 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: definitions, static aspects and dynamic analysis, stability improvement
- transient angle stability (large disturbances): analysis and improvement
- voltage stability: introduction
- short-term voltage stability: instability mechanisms and countermeasures
- long-term voltage stability: fundamentals dealing with transmission, generation and load, instability caused by smooth parameter changes, mechanisms of instability caused by large disturbances and countermeasures.

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 relatively complex nonlinear systems. In particular, its improves the ability to interpret results coming from the simulation of differential-algebraic systems. It is also an opportunity to outline the controllers used traditionally by industry.
The tools used to this purpose (such as SIMULINK under MATLAB) prove useful in other disciplines than power system engineering.
Finally, the course also 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 (Analysis and operation of electric energy networks) must be known before dealing with the more specialized material of this course. Obviously, a course whose table of contents is similar to that of ELEC0029 may be suitable. |
|
Planned learning activities and teaching methods :
|
| Small case studies are presented in each module of the theoretical course. They rely on simulation and analysis tools of the type that the student will have to use by him/herself.
The student is asked to perform a personal work using a SIMULINK-based model. The student has to understand this model in detail and is requested to add one or several components.The questions deal with a wide range of chapters in the theoretical course. Eventually, the student produces a report (on which questions can be asked orally).
The whole course is taught in English. |
|
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 professor (see below).
For the first part of the course, lecture notes (in French) are also available and downloadable from the same place. |
|
Assessment methods and criteria :
|
| The grade relates to the above mentioned personal work.There is no written or oral exam. |
|
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. |
