SummaryThe Power Systems part of the course introduces students to the analysis of power systems in per-unit and absolute values using single-line diagram representations of balanced and unbalanced power supply systems. Students will perform load-flow and short-circuit studies, and will be exposed to the analysis of the fundamental techno-economic issues in the design of large power systems, involving long term planning, mixed fuel resource/energy scheduling and power system plant investment appraisal.

The Power Electronics part of the course introduces students to the basic power electronic devices and converter circuits used to process electrical power. Students are introduced to some of the wide range of applications where power electronic systems are currently used.

The Electrical Machines part of the course provides students with a good understanding of the construction and steady state performance of induction motors and generators. Students will study and apply single-phase quivalent circuit to analyse induction machines.

The Power System Group Design Project brings all aspects covered by the Power System part, and the laboratory brings together both the machines and power electronics aspects of this course.

1. Power Laboratory: Two sessions, 3 hours/session.
2. Power System Group Design Project:
Groups of 4, 5 or 6 students design, cost and evaluate the expansion of a power supply system.
The exercise starts in Week 6 of the second semester, and continues for the rest of the semester. Students submit a group report which is assessed. Student performance within the group is assessed by their peers.
