Course purpose

The aim of this course is to introduce and investigate the use of power electronics in power systems, both at transmission and distribution level. In particular, the configuration, design and control strategy for the different devices will be treated during the course. At the end of the course the student should have a proper understanding of the different problems that can be encountered at the different voltage levels in the power systems and how to approach and solve them.

Course literature

The course literature is mainly based on handouts that are handed throughout the course. In addition, for the first part of the course the following book will be used as main textbook:

• N.G. Hingorani and L. Gyugyi, "Understanding FACTS: concepts and technology of flexible AC transmission systems"

 The textbook is available at Cremona, at the Student Union. The textbook contains essential materials for the part of the course related to the application of power electronics at transmission level. 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

The course consists of scheduled lectures, tutorials and computer exercises as follows:

Lectures: Lectures typically take place on Tuesdays (8-10), Wednesdays (8-10) and Fridays (8-10, 10-11:30). This scheme might be affected by changes, which will be communicated to the students in due time.  Check the schedule in Time-Edit for updated information in both time schedule and location. 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: Tutorials will be given during lecture hours, according to the course plan below

Computer assignments: computer assignments are based on the simulation software PSCAD and are scheduled every Tuesday 10-12. 

 

Changes made since the last occasion

No major changes have been implemented. Updated guest lecture from Hitachi Energy on FACTS and HVDC systems. Minor updates in PSCAD exercises

Learning objectives and syllabus

Learning objectives:

1. Describe the technical characteristics and performance of the electric power system with and without power electronics support.
2. Identify, formulate and analyze complex problems in electric power engineering, such as power system stability, power system bottlenecks and power quality phenomena.
3. Make choices of solutions and justifications due to relevant criteria's of the problems and opportunities associated with the use of different electric power components and systems.
4. Identify, select and use different power electronic based solutions for improving both the steady state and the transient performance of the power system.
5. Carry out electric circuit modeling and analysis using the simulation tool PSCAD/EMTDC.

Study plan

If the course is a joint course (Chalmers and Göteborgs Universitet) you should link to both syllabus (Chalmers and Göteborgs Universitet).

Examination form

A written exam at the end of the course will decide the final grade. In addition, PSCAD/EMTDC exercises must be completed and approved in order to pass the course.

Calculator: Chalmers approved calculators are allowed and recommended at the examination: Casio FX82…, Texas TI30…, Sharp ELW531. Other calculators will be inspected and the flash memory will be reset
