Unit of study_

# ELEC3203: Electricity Networks

### 2025 unit information

This unit of study provides an introduction to electrical power engineering and lays the groundwork for more specialised units. It assumes a competence in first year mathematics (in particular, the ability to work with complex numbers), in elementary circuit theory and in elements of introductory physics. A revision will be carried out of the use of phasors in steady state ac circuit analysis and of power factor and complex power. The unit comprises an overview of modern electric power system with particular emphasis on generation and transmission. The following specific topics are covered. The use of three phase systems and their analysis under balanced conditions. Transmission lines: calculation of parameters, modelling, analysis. Transformers: construction, equivalent circuits. Generators: construction, modelling for steady state operation. The use of per unit system. The analysis of systems with a number of voltage levels. The load flow problem: bus and impedance matrices, solution methods. The control of active and reactive power. Electricity markets, market structures and economic dispatch.

## Unit details and rules

#### Engineering

Study level Undergraduate School of Electrical and Computer Engineering 6
 Prerequisites: ? None None None This unit of study assumes a competence in 1000 level MATH (in particular, the ability to work with complex numbers), in elementary circuit theory and in basic electromagnetics

At the completion of this unit, you should be able to:

• LO1. Understand and describe the operation of electric power systems.
• LO2. Apply circuit and phasor analysis techniques and the per-unit system to model and analyse three-phase electric circuits under balanced conditions.
• LO3. Develop steady-state models of fundamental electric power system components, including transformers, transmission lines and generators and use them to build and analyse a simple power system model,
• LO4. Formulate the power flow problem, solve it using different approaches, and assess their performance.
• LO5. Understand and explain the fundamental principles of economic dispatch and power system control.
• LO6. Communicate scientific information appropriately, both orally and through written work.
• LO7. Engage in team and group work for scientific investigations and the process of learning.
