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.

1. Electricity and Society
2. Per Unit System
3. Power-flow Analysis:
4. Fault Analysis
5. Power Systems Stability
6. Renewable Energy
7. Power Quality
8. Substation Layout
9. Transformers
10. Protection
11. Rotating machines
12. Power Electronic Control

Laboratories: All laboratories are compulsory.

Power-flow Lab. will be run first week in March in the CAE Laboratory.
You will have been automatically allocated to one of these two sessions.

Two other labs. (Synchronous machine, Harmonics & Loads and High Voltage) will be run by Dr Jeremy Watson.

Learning Outcomes

  • At the conclusion of this course you should be able to:

  • LO1: Demonstrate a comprehensive, theory-based understanding of power system structure, components, and behaviour when interconnected (WA1)

  • LO2: Recognise and explain power system components, including power generation technologies, power storage technologies, including their advantages and disadvantages, as well as design of different substation layouts, and merit (WA3, WA5)

  • LO3: Perform calculations associated with electrical machines, and typical power
    systems analysis under both steady-state and transient/dynamic conditions (WA1, WA2, WA4)

  • LO4 Understand and design an appropriate protection system (WA3)

  • LO5: Appreciate the social and technical history and present state of electrical power system, including electricity markets and pricing mechanisms (WA6, WA8, WA11)
    • University Graduate Attributes

      This course will provide students with an opportunity to develop the Graduate Attributes specified below:

      Critically competent in a core academic discipline of their award

      Students know and can critically evaluate and, where applicable, apply this knowledge to topics/issues within their majoring subject.

      Employable, innovative and enterprising

      Students will develop key skills and attributes sought by employers that can be used in a range of applications.

      Biculturally competent and confident

      Students will be aware of and understand the nature of biculturalism in Aotearoa New Zealand, and its relevance to their area of study and/or their degree.

      Engaged with the community

      Students will have observed and understood a culture within a community by reflecting on their own performance and experiences within that community.

      Globally aware

      Students will comprehend the influence of global conditions on their discipline and will be competent in engaging with global and multi-cultural contexts.
