Summary of Content

This module examines electrical systems comprising of generation, transmission, distribution and load. An understanding of electrical power system components and their applications will be developed. Appropriate analytical techniques will be developed and these will be applied to the analysis of systems and components to determine operating performance. Components introduced in the module include power transformers, multiphase transmission systems, electrical motors and smart grids.


Taught Syllabus will cover the following areas: Overview of a typical electrical distribution and utilisation system:- 3-ph/1-ph supply, interconnecting cables, transformers, loads (resistive and reactive including motors), over-current protection. Approaches to system analysis. Fundamental ac circuit theory. 3-Phase ac circuits: Balanced 3-phase systems, phasor representation. 3-wire and 4-wire connections, star and delta. Application to 3-phase LV distribution schemes. Analysis of resonant circuits. Power factor and power factor correction. Analysis of 3-phase systems (current, voltage relationships, complex power and power factor). Transformers. Principle of operation. Voltage, current and turns ratio. Design and analysis of practical transformers (construction, features, characteristics, losses and magnetising current). Equivalent circuit and its application.. DC Motor. Construction and features, torque production, pm and separately excited machines, Characteristics and applications. Analysis using equivalent circuit model. Induction Motor: Principle of operation (rotating field, induction and slip). Construction and features. Losses. Characteristics (starting and running) and applications. Analysis using equivalent circuit model. Electrical system design: Overview of conventional and renewable energy generation systems.

Learning Outcomes

On completion of this module the student should be able to:1. Describe in detail the features, characteristics and application of a range of electrical system components2. Analyse an overall electrical system comprising of a supply, distribution and load.3. Understand the usage of each electrical system architecture and sub-component, with an understanding of factors affecting their efficiency and operation.4. Use analytical techniques to investigate, characterise and modify the behaviour of electrical system components such as distribution transformers and 3-phase networks.5. Use analytical techniques and specialist software simulation tools to model and compute the behaviour of complex electrical circuits, deriving fundamental metrics such as phase relationships, voltage relationships, resonant frequencies, power factor, transformer efficiencies, losses and regulation.6. Perform fundamental calculations and design studies relating to power generation.7. Carry out a structured design project, incorporating all aspects of system design for a small-scale electrical system.

Teaching / Learning Strategy

The module will consist of lectures, tutorials, supported laboratory exercises consisting of computer based simulations, web-based resources and communication tools and guest lectures from industry. These will be underpinned through a study pack, demonstrations, practical exercises and directed studies. Students will be encouraged to learn independently through problem solving, and design exercises.
