Overview:

This module provides students with detailed knowledge of the design, performance and analysis of electrical power systems. The module aims to achieve competency in using analytical methods for understanding the design and operational behaviour of electrical power systems under steady-state and transient conditions. It provides technical knowledge in electrical power system technologies such as generators, cables, distribution and protection, and end-use equipment so as to appreciate the design features for different electrical power distribution and electrical propulsion systems.

Through computer based software and with understanding of their algorithms, students become proficient at calculating performance parameters in small and large scale electrical power systems used in electric vehicle, electric ship or grid systems.
