This electric power systems course encompasses the concerns of bulk electrical energy, its generation, the bulk transmission, local area distribution and final consumption (the load) as needed by industry, commerce and households. It is a complex subject, as it involves large scale power system interactions involving power flow, transient stability and system protection, and depends on a multitude of component level characteristics. Renewable generation has added to this complexity. Students in this course will learn analysis techniques for power systems under both steady-state and transient conditions. Basic principles of protection are covered, as are relevant electrical component level concepts, including generators and transformers. The basics of renewable and other energy sources are also covered.

Topics covered include:

• Electricity and Society
• Per Unit System
• Power-flow Analysis
• Fault Analysis
• Transient Stability
• Renewable Energy
• Power Quality
• Substation Layout
• Transformers
• Earthing
• Rotating Machines
• Power Electronic Control

Learning Outcomes

At the end of this course, the student will be able to:

1. Understand the laws and concepts governing the behavior of an interconnected electrical power system.

2. Understand the different types of generation and storage technologies.

3. Perform calculations on the potential of renewable power generation.

4. Understand the past and present structure of the electrical power system and be familiar with the wholesale electricity market (including societal aspects that have influenced the development).

5. Perform power-flow analysis and understand the way different components can affect the power flow.

6. Perform balanced fault calculations.

7. Perform transient stability analysis using equal area criteria.

8. Understand and perform calculations for electrical machines (generators, transformers and motors).

9. Perform calculations for earth grids.

10. Understand Substation layout.
