| Course contents : | 1st part : Modelling of components and controls
- dynamics of the synchronous machine: time constants, inductances, state equations, per unit systems, rotor motion
- power system modelling under the quasi-sinuosidal approximation
- induction machine: modelling and behaviour after a disturbance
- turbines and speed governors: thermal power plants, hydro power plants
- excitation systems and automatic voltage controllers
- static var compensators
- series compensation : fixed and variable (FACTS devices).
2nd part. Stability
- stability notions in electric power systems : definitions, links with notions from system theory
- small-signal angle stability : analysis of the one-machine infinite-bus system, then of large systems, modal analysis. Stability improvement : design of controllers aimed at damping oscillations, in particular the power system stabiliser
- transient (angle) stability : analysis (equal area criterion) and improvement
- frequency stability
- voltage stability : analysis of short- and long-term voltage collapse scenarios, stability improvement. Demonstration of the ASTRE software.

| Course objective : | Graduate course dealing with Power System Dynamics : modelling, control and stability. |
|
| Prerequisites : | ELEC029 or an equivalent course. |
|
| Workshops : | Examples from a SIMULINK (MATLAB) model library are given during the lectures. A personal assignment is requested, using that tool. |
|
| Organization : | Course taught at the first and/or second term, according to the audience. |
|
| Written notes : | Detailed lecture notes available on paper and in electronic (PDF) format. |
|
| Assessment : | A personal assignment is given to the student, which deals with various parts of the course and requires to use the SIMULINK power system library. A written report is requested with possibly an oral presentation. |
