In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

Course specific prerequisites

ENM050 Power system analysis, or equivalent.


The overall aim of this course is to further equip students with knowledge in power system operation. The main topics treated in this course include fundamental of frequency control, simplified models of synchronous generators for stability studies, transient angle stability, voltage stability, principles of protection of power system components, state estimation function within SCADA/EMS system. Throughout the course, students will have an opportunity to be exposed to the power system laboratory to learn more about the stability issue. Students will also be trained and introduced with the use of the commercial software for power system simulation through the project work and demonstration.

Learning outcomes (after completion of the course the student should be able to)

- Understand basic frequency control actions in power systems being subject to contingency conditions.
- Understand simplified models of synchronous generators for stability studies
- Demonstrate the understanding of transient angle stability problem and methods to improve stability.
- Simulate and analyze power voltage stability problem and analyze the problem under different scenarios.
- Demonstrate the basic understanding of basic protection schemes for various power system components.
- Understand the main functions of Supervisory Control and Data Acquisition (SCADA) and Energy Management System (EMS) and Power System State Estimation.
- Understand issues related to emergency control and the restoration process after the system blackout.
- Collaborate to work in team to manage project, lab assignments.


The course will cover the following topics:
- Frequency control: Overview of frequency control, turbines and governing system, primary control, control of active power generation, automatic generation control.
- Overview of power system stability; Angle stability, voltage stability, frequency stability; Simplified models of synchronous generators for stability studies;
- Transient (angle) stability: The swing equation; the equal-area criterion; critical fault clearing time, design methods for improving transient stability.
- Voltage stability: Reactive power capability of the synchronous generators, armature and field current limiters, P-V, Q-V curves for stability analysis, scenarios of voltage collapse; effects of load characteristics on voltage stability; methods to improve voltage stability.
- Power system protections: Overview of protection, transmission system protection (distance), distribution system protection;
- Introduction to SCADA/EMS; State Estimation function.
- Power system blackouts: review of recent large power system blackouts in the world; Emergency controls and restorations.


This course consists of scheduled lectures (17x2 hours) tutorials (12x2 hours), laboratory experiment (1x2 hours), project consultations (5x2 hours), and ARISTO demonstration (1x1 hour).


Lecture handouts. Lectures are mainly based on a number of text books:

[1] P. Kundur, "Power System Stability and Control", EPRI Power System Engineering Series, MacGraw-Hill Inc., 1994. Very extensive book. Highly recommended.
[2] H. Saadat, "Power System Analysis", Second Edition, Mc Graw Hill, 2002.
[3] T.V. Cutsem and C. Vournas, "Voltage Stability of Electric Power Systems", Springer, 2008.
[4] J.D. Glover and M.S. Sarma, "Power System Analysis and Design", Third Edition, Brooks/Cole, 2002.

The examination is based on a traditional closed-book written exam and submitted laboratory and project reports. You must have the reports of lab and project approved in order to pass the course. The final grade will however be based on only the final examination and with the normal grades of 5, 4, 3 and U (fail). Only Chalmers approved calculators will be used in the exam.
