Unit Description and General Aims
This unit of study presents a study of electrical power systems, their analysis and operation. The students will be introduced to fundamental concepts in the unit will cover topics of generation, transmission, distribution, analysis, and operation at introductory levels. Concepts of power, frequency, and voltage control will be examined and different types of transmission/distribution systems and their associated systems will be presented. Models of long, medium and short transmission lines will be introduced to assist in calculation of power, voltage, current and power factor in an electrical system. Fault analysis in three-phase balanced systems will be studied together with fault Calculations in Power Systems. An outline of the electricity distribution in the deregulated Australian power industry will be given, and network calculations and the bus-admittance matrix will be covered. The Gauss-Siedel, Newton-Raphson, and Fast Decoupled load flow analysis methods and their application to the solution of complex networks will be introduced.
The unit aims to cover important international standards (IEC 61850) for substation automation, which will contribute to students' understanding of the significant impact on how electric power systems are designed and built for the future. The model driven approach of IEC 61850 is an innovative approach and requires a new way of thinking about substation automation. This will result in significant improvements in the costs and performance of electric power systems.
Substation Automation (or Data Communications for Substation Automation), including the protocols such as DNP3, IEC 61850, and IEC 60870-5-101/103 as well as the use of LANs/WANs for real-time communication in power distribution systems (both inside substations and between them) will be discussed. IEC 61850 alone is very complex and is a ‘hot topic’ in the Power Industry today.
Lectures will be used to introduce the key concepts and knowledge complemented by laboratories, and to extend and apply this knowledge. The tutorials focus on applying knowledge in solving engineering-related problems. Assignments are given to students to help them reinforce the knowledge gained during lectures/tutorials and to improve their information seeking abilities.
On successful completion of this Unit, students are expected to be able to:
- Demonstrate knowledge of the basic principles of electric power systems, the components thereof, and the respective configuration and operation.
- Apply techniques of power flow solutions including calculations of voltage, angles, losses, generated reactive power, slack power, etc.
- Critically analyse transmission systems, and identify solutions to power system problems.
- Define the details and functions of Substation Automation
- Understand the various Substation Automation Architectures
- Understand, identify and apply IEC 61850

Web & Video conferencing software
Students will be provided with Blackboard Collaborate (or similar) for video and web conferencing. This will allow them to attend lectures, interact with lecturers and fellow students, and use the Remote Lab facility. Students will be required to download the latest version of Java and .NET in order to use these packages.
For ease of communicating with peers and lecturers, installation of this package is recommended.
Word, PowerPoint and Excel
It is recommended that students install at least a 2007 version of the Microsoft Office. Older versions will work, but sometimes create issues with file compatibility. If individuals are reluctant to use these, they can also use Open Office (www.openoffice.org).
As students are co-operating with people from throughout the world with a multitude of different PCs, it is recommended that they have good quality up-to-date virus detection software installed. The free version of AVG is sufficient. A thorough automated scan of computers at least once a week is recommended.
Learning Management System
EIT uses a state-of-the-art learning management system (Moodle) for lecturing and interacting with lecturers and fellow students. Students can chat, socialize, and collaborate on projects with similarly motivated and enthusiastic course participants.
Computing resource requirements
Students’ computers should have an Intel Core Duo CPU and 2 Gigabytes of RAM. Hard disk space available should be at least 2 Gigabytes free. If necessary the built-in hard drive can be augmented with an inexpensive USB drive. No particular special graphics card is required. The operating system should be Windows with Windows 7 Service Pack 1 as a minimum.
An ADSL Internet connection with a minimum speed of 128 kbps down and 64 kbps up is recommended.
Good quality headset and low cost web cam
Students will require a good quality stereo headset with analogue or USB connectors. In addition, a low-cost USB webcam is recommended. Students should budget in the order of $30 for a headset and $20 for a webcam. This will vary from country to country.
For difficulties with other online materials the lecturer should be contacted. Technical material will be accessible 24/7 through the online portal.
