ECE3051 · Electrical energy systems

Overview

The unit begins by considering electrical machines, looking at DC machines, induction motors, synchronous motors and other types of motors under fixed and variable speed operation. Then thyristor rectifiers and switched power converters are presented, looking at their use for electrical energy conversion in general and variable speed motor control in particular. Finally, single and three phase AC networks, power factor correction, and electrical power generation, transmission and distribution networks are explored. Particular focus is given here to three phase transformers, transmission line modelling, quality of electrical supply, electrical protection systems, and power system control.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 40% Final assessment: 60% This unit contains threshold hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.
