## 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 gears 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.

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.
