Summary of Content

This module examines topics relating to electric power generation, transmission, distribution and utilisation. This will include examination ofindividual power system components such as generators, transformers, overhead lines, underground cables, switchgears and protection systems etc., as well as analysis of load flow and system fault conditions which are required for power system design and operation. It will also investigate the integration of distributed generations into an existing power system and the issues in relation to power system tariff and power quality.

Syllabus

The taught syllabus will cover the following areas: Power system components: Power generators, transformers, overhead lines, underground cables, switchgears, relays, load, voltage control, frequency control. Electrical Power Generation: Generation methodologies, including nuclear, coal, oil, gas, water, solar and wind. Advantages/disadvantages of different methodologies from both economic and technical viewpoints. Electrical Power Distribution: Factors affecting the distribution of electrical power to industrial, commercial and domestic consumers. Load cycles on a daily and an annual basis. Economic factors. Plant within the distribution system, including overhead lines, cables, transformers, rotating machines and switchgear. 3-Phase ac circuits: Balance 3-phase systems, phasor representation. 3-wire and 4-wire connections, star and delta. Applications to 3-phase LV distribution schemes. Analysis of 3-phase systems (current, voltage, complex power and power factor). Power System Analysis: Per-Unit system, load flow analysis, fault calculations, integration of distributed generation to an existing power system, and power system protection. Economics of Electrical Power: Electricity Market operation, Pool pricing. Tariff structures. Real time pricing. Power Quality: Definition, categorisation, syptoms, causes, national/international standards, and measures for problem mitigation.

Learning Outcomes

On completion of this module the student should be able to:Understand different types of electricity generation such as conventional generation and renewable generation and their associated characteristics.Understand the features, characteristics and application of a range of electrical system components.Analyse the technical and economic constraints imposed by the system on the choice of individual components and subsystems.Analyse an electrical system comprising of a supply, distribution and load through manual calculation and using a range of appropriate tools and techniques.Specify critical parameters for distributed generation integration, accounting for both technical and economic factors.Analyse the quality of electrical power supply through analysis of the categorisation of power quality problems, and identification of their causes and suitable solutions.

Teaching / Learning Strategy

Students will be encouraged to learn independently through problem solving a given system. However, this will be underpinned through a study pack, demonstrations, practical exercises, directed studies, lectures and tutorials, computer-based support analysis, web-based resources and communication tools, guest lectures from industry.
