ELEC3105 - Electrical Energy

Last modified by Leon Luo on 2023/01/06 13:50


This course on electrical energy is designed for third-year students who are pursuing a degree in electrical engineering. It is a core course that aims to give students an understanding of the principles and performance of devices and components related to the generation, transmission, distribution, and utilization of electrical energy. However, this course is not core for students studying quantum engineering and telecommunication engineering. The course also aims to provide in-depth knowledge on the analysis and design of these circuits and devices. To be eligible for the course, students must have completed two prerequisite courses, ELEC2134 - Circuits and Signals and ELEC3115 - Electromagnetic Engineering. It is essential that students have a basic understanding of circuit theory, electromagnetics, and concepts such as AC sinusoids, phasors, and impedance.

The syllabus for the course includes a wide range of topics related to electrical energy, including energy supply systems, transmission and distribution systems, energy conversion, and the utilization of electrical energy. It also covers renewable energy sources such as wind and solar energy, as well as energy efficiency and the environmental aspects of energy. The course will introduce students to three-phase theory and balanced three-phase AC circuits, and will cover the analysis of power transformers and energy conversion in different types of machines, such as DC machines, induction machines, and synchronous machines. The current shift towards greener generation and more efficient electricity consumption presents a challenge in decoupling economic growth from energy demand and fundamentally changing the way we think about energy. The goal of the course is to establish the foundation of all aspects of electrical energy and introduce students to key components of the electrical network.


These concepts are studied through course content, mainly lecture notes and course recommended textbooks. Please note, unless referenced from another source, please assume the following information presented is interpreted, studied, and re-expressed from the course content. Furthermore, please refer to the course content directly, e.g. ask the lecturer or read the textbook, for the most relevant knowledge required for the course.
