This course is designed to build on Electric Power and Machines (ENEL382) by giving a more in-depth treatment of some areas (power-flow, fault analysis and protection) while covering in detail new areas such as reliability assessment, power quality, electromagnetic transients, harmonic analysis and substation earthing. New developments in electrical power systems are covered. In the process of teaching this course and by using a design assignment as a problem-based learning tool, students will learn how a large real power system will perform and how to engineer solutions to identified problems.

This course builds on the knowledge gained from ENEL382 by developing further an understanding and the analytical tools for assessing the power systems' performance under steady-state and transient conditions. These tools are related to practical problems and the wider issues associated with power system planning. Hands on experience with practical tools for the field engineer will be obtained through the assignment as well as teaching the use of lateral thinking.

Topics include:
1. Power-Flow: AC/DC Power-Flow, Motor Starting studies
2. Fault: Balanced & Unbalanced, Sequence (Symmetrical) Components, Sparsity techniques
3. Reliability
4. Protection
5. Power Quality
6. Power Electronics in Power Systems
7. Substation Earthing design

Learning Outcomes

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

  • LO1: Demonstrate an advanced application-focused understanding of power system behaviour, accounting for power quality, reliability (WA1)

  • LO2: Perform calculations and modelling for the design of power systems, including for protection systems and substation earth grids (WA1, WA3, WA5)

  • LO2: Apply analysis techniques for steady-state and transient power systems, power system fault analysis, and power system protection (WA2, WA4)

  • LO4: Identify and critically evaluate the latest technical advancements for electrical power systems, accounting for technical, social, fiscal, and environmental factors (WA2, WA3, WA4 WA5, WA6, WA7, WA11, WA12)

  • LO5: Communicate the design of electrical power systems in written and schematic form (WA10)
    • 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.

Tutorial/Design Laboratory:
This Tutorial runs every Tuesday 2 pm – 5 pm in Elec 209 CAE Lab. for term 1. Although there is no mark assigned for the tutorial itself the purpose of it is for you to work on your major design assignment and obtain assistance when needed. The CAE lab is booked for you to work on your design assignment so you have priority for the computers during this period. Please use it for this and work on your assignment consistently throughout term 1. Do not leave it to the last few weeks.

Please note the following regulation (UC Calendar/Maramataka 2022, page 38):
‘3. General Conditions
(a) A student seeking course credit must engage satisfactorily in all required course-related activity, work and assessment specified in the course outlines.
