Power Transmission and Distribution Networks (ENG323)

Organisational Unit Engineering and Energy
Credit Points 3
Availability MURDOCH: S2-internal
Teaching Timetables Murdoch S2
Description This unit studies the key concepts behind the transmission and distribution of electrical energy. It covers topics such as transmission line modelling, distribution transformers, overhead lines, power flows, symmetric fault analysis, three-phase symmetrical components and non-symmetric fault analysis. This unit is supported by software simulators for performing load flows and fault analyses of three-phase electrical power networks.
Unit Learning Outcomes On completing this unit, students should be able to:
1. Apply appropriate models for transformers, transmission lines and generators
2. Formulate and solve non-linear load-flow equations and verify results using a power systems simulator
3. Demonstrate interconnected power system operation through modelling and analysis
4. Develop and analyse system models for unbalanced faults and selection of protective devices
5. Apply problem-solving and research methods as part of an advanced design and development of power transmission and distribution networks
6. Demonstrate innovative and advanced solutions as part of the unit tasks
7. Communicate with engineering teams and apply advanced technical knowledge
Timetabled Learning Activities Lectures: 1 x 2 hours per week; Workshops: 1 x 2 hours per week; Laboratories: 1 x 2 hours per week.
Unit Learning Experiences Lecture materials present an introduction to the purposes and functions of electrical power networks. The concepts introduced in lectures are reinforced using problem sets that help explain terminology and enable students to apply a range of mathematical tools to analyse and design power networks. Power flow simulators are used to test ideas and to run a number of 'what if' scenarios that encourage curiosity into the subject matter and that highlight the consequences of using untested assumptions.
Other Learning Experiences Students may need some outside of class time to undertake aspects of the lecture contents, projects design and analyses.
Assessment The assessment for this unit is comprised of the following :
Laboratories (5%): The laboratories provide practical application of the knowledge gained in the lectures through simulation studies and reporting of findings.

Project Work (30%): There will be two projects and students will work in groups to analyse and design power systems where power flow simulators are used to test designs. Design objectives, procedures, testing and conclusions are presented in a final report.

Topic Test (15%): There will be two topic tests based on the contents covered throughout the semester.

Final Exam (50%): The final exam is a standard closed book exam based on all the contents covered during the semester, tests the understanding, knowledge and analytical skills developed in the unit.
Prerequisites ENG297/ENG243 Circuits and Systems II; MAS220/MAS261 Mathematical Methods or MAS221/MAS208 Mathematical Modelling.

Internet Access RequirementsMurdoch units normally include an online component comprising materials, discussions, lecture recordings and assessment activities. All students, regardless of their location or mode of study, need to have access to and be able to use computing devices with browsing capability and a connection to the Internet via Broadband (Cable, ADSL or Mobile) or Wireless. The Internet connection should be readily available and allow large amounts of data to be streamed or downloaded (approximately 100MB per lecture recording). Students also need to be able to enter into online discussions and submit assignments online.
