Unit Description and General Aims
This unit requires mathematical foundations to solve power system operation problems. The unit will provide students with essential knowledge using mathematical techniques to analyse power systems, both under steady state and dynamic conditions. Power systems will be presented as complex networks comprising generators, loads, transmission lines, various apparatus and equipment, e.g., bus bars, switchgears, transformers etc. Concepts such as power, frequency, and voltage control will be examined and different types of transmission/distribution systems and their associated gears will be presented. Models of long, medium and short transmission lines will be introduced to assist in the calculation of power, voltage, current and power factor in an electrical system. Fault analysis in three-phase balanced systems will be studied together with fault calculations in power systems. The unit provides with an understanding to evaluate the response of the complex power system to variation of loads, and to determine how the system can be controlled to supply the loads reliably, while it is economical and safe to the environment.
Lectures will be used to introduce the key concepts and knowledge complemented by laboratories to extend and apply this knowledge. The tutorials focus on applying knowledge in solving engineering-related problems. Assessments are given to students to reinforce their knowledge gained during lectures/tutorials and to improve their information seeking abilities.
On successful completion of this Unit, students are expected to be able to:
- Demonstrate knowledge of the basic principles of electric power systems, the components thereof, and analyze the respective configuration, operation and modelling.
