Module summary

Module code: ELEC1041
Level: 7
Credits: 15
School: Engineering and Science
Department: Engineering
Module Coordinator(s): Yehdego Habtay



To design power systems in terms of plant ratings and short circuit loading to specified values of performance. Understand the impact of power distribution on communities and society.

Learning outcomes

On successful completion of this module a student will be able to:
1 Analyse and critically reflect on short-circuit fault levels, load flow performance and economic operation of the system with the aid of commercially available simulation software.
2 Critically reflect on and analyse the operation of transmission lines and evaluate the characteristics of DC and AC power transmission systems.

Indicative content

An over-view of power system operation, load forecasting, merit-order scheduling and dispatch. Load flow analysis, Gauss-Seidel and Newton-Raphson solution techniques. Fault calculations, steady state and transient stability performance, machine inertia, equal area criterion, effect of automatic voltage regulators and governors.

Use of software packages for analysis and design of power systems. Power system control: power flow theory, frequency and voltage control, flexible AC transmission systems, equipment representation, reactive power compensation and active power flow control, combined active and reactive power control, overhead line parameters.

Power system protection: system protection components, radial system protection, protection of two source-systems, bus protection, transformer protection, pilot relaying, computer relaying. Transmission lines: design considerations, steady state and transient operation, DC transmission technology.

Teaching and learning activity

Formal lectures, tutorials, and laboratory work provide practical experiences of design and testing of power electronic converter systems. The laboratory work will consist of simulation and hands-on design and implementation, coupled with a reflective analysis of the results.
