This unit aims to develop the foundation for exploring tools and methods to analyse electric power systems. It provides an introduction to main elements such as generators, transformers, transmission lines, and loads and their mathematical models. Then using these models, the unit presents analytical tools to analyse the power system in steady state and under fault conditions. In particular, tools and techniques for power flow, symmetrical and unsymmetrical faults, voltage control, frequency control, and system stability will be studied in detail. Finally, electromagnetic transients in power systems will be introduced.
The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.
