Course purpose

The main aim of this course is that students should develop and demonstrate their knowledge and capability to model major power system components in order to analyze and control the voltage, frequency and power flow of a simple power system under steady-state and dynamic conditions using theoretical methods, simulation tools and laboratory setups.

Course literature

The following book is the main textbook used throughout the course.

  • Hadi Saadat, Power System Analysis, 3rd Edition, PSA Publishing, 2010

 The textbook is available at Cremona (www.chalmersstore.se) at the Student Union. The textbook contains essential materials for the course. It should, however, not be viewed as the only source of information needed to prepare for the examination. Additional materials will be provided during lectures and/or be made available on the course homepage.

Course design

This course consists of scheduled lectures (19x2 hours), tutorials (13x2 hours), project consultation (7x2 hours), and laboratory work (3x1 hour) during 8 study-weeks.

 

Lectures: Lectures usually take place on Tuesdays (13:15-15:00), Thursdays (13:15-15:00), Fridays (13:15-15:00). There will however be some changes due to teachers’ unavailability. Check the schedule in Time-Edit for updated information in both time schedule and location: https://se.timeedit.net/web/chalmers/db1/public/#. Topics treated in lectures are given in the table above. Numerical examples will be given in the lectures to help clarify the theory wherever necessary.

Tutorials: Numerical exercises will be given during tutorial sessions and in your home-work. Tutorials normally take place on Tuesdays (15:15-17:00) and Thursdays (15:15-17:00). There will however be some changes due to teachers’ unavailability. Check the schedule in Time-Edit for updated information.

Project Work: In addition to tutorial exercises, students are expected to work on a computer-based project during 8 weeks starting from the first week of the course. The project will be carried out in a group of 3-4 students. In the project, students will analyze a practical power system using the power system software PSS/E and MATLAB/SIMULINK. The software is available in Windows based PC and its student version (PSS/E Xplore v34.3.2) can be downloaded for free from Siemens at https://w3.usa.siemens.com/smartgrid/us/en/transmission-grid/products/grid-analysis-tools/transmission-system-planning/transmission-system-planning-tab/Pages/university.aspx . Download using Internet Explorer and install it in your computer during the 1st study week. You are free to choose to work at your own time. Seven occasions for project consultation will be given in the computer labs (room ES61 or ES62, check Timeedit for updated information) in the E-building, in two separate sessions. Session 1 usually takes place on Mondays from 10:00 to 11:45, Session 2 usually on Mondays from 13:15 to 15:00. Book your session at the course homepage. The detailed description of the project will be provided at the start of the project. The project report is compulsory and is marked for your final grade.

  • Long transmission line laboratory demonstration: There will be a 45 min laboratory demonstration on long AC transmission line operations. The demonstration aims at showing some typical loading conditions of long transmission lines. The demonstration will take place during study week 4. Each group will need to go for one time only. Book your time on the course homepage. The participation is compulsory.
  • Voltage control laboratory: This lab focuses on the excitation control of the synchronous generator. The participation is compulsory.
  • Frequency control laboratory: This lab focuses on the speed and active power control of the synchronous generator. The participation is compulsory.

Changes made since the last occasion

  • The project work in PSS/E will start on Monday from study week 1 before the first lecture,
  • One new project assistant Shoaib Salim Inamdar,

Learning objectives and syllabus

Learning objectives:

1. Perform basic state evaluation of a small network using phasor-diagram, loss summation and two-port equations methods, and explain basic voltage control principles. 


2. Model major components of power systems: three-phase power transformers, short-, medium- and long-transmission lines, loads, generators, and reactive power compensation elements. Analyze the impact of different loading conditions on a transmission line. 

3. Describe and use per unit system to perform studies in power systems.

4. Explain and implement different means for voltage control and reactive power compensation in a power system.

5. Explain and implement different stages of frequency control and corresponding active reserves in a power system.

6. Model and analyze the power systems under a balanced fault condition and explain the meaning of grid short circuit capacity

7. Apply the above knowledge to analyze a small practical transmission network under normal and faulted operating conditions using offline power system simulation software. Document and present the results with appropriate analysis.

8. Collaborate and work in a team with different backgrounds for the computer and lab project as well as for other occasions throughout the course. 

9. Argue different ethical aspects that need to be considered in the design and operation of electric power systems.

Study plan

Examination form

Trial exam: A trial exam will be held in the 4th week of the study period. The trial exam will give maximum 10% to be added to the final score and a minimum of 0. The trial exam is NOT compulsory but highly recommended.

Examination: Closed-book examinations. The examination is based on the project work and the “closed-book” written exam. The distribution of the final grade will be: i) project (20%), and ii) exam (80%). You will have to pass both in order to pass the course. The participation in all the laboratory demonstration and exercises is compulsory in order to pass the course.  The final grade will be 5, 4, 3 and U (fail). For a total of 30 points, to get a 5, you need 24 points or above (80%), and to get a 4, you need 18 points or above (60%), and to get a 3, you need 12 points or above (40%).

For example, if you get 4% in the trial exam, 80 points (out of 100 points) in the project, and 18 points (out of 30 points) in the final exam, you final point will be P= 30 * 4% + (80 * 0.3) *20% + 17 * 80% = 19.6, and this gives you a grade of 4. The maximum point one can get is Pmax = 30 * 10% + (100 * 0.3) * 20% + 30 * 80% = 33.

Calculator: only Chalmers approved calculators can be used in examination: Casio FX82…, Texas TI30…, Sharp ELW531…
