| Course description | Electrical Machines: This module provides students with a good understanding of the steady state and dynamic performance of synchronous motors and generators, derived from the starting point of airgap MMF vectors. Power Electronics: This module aims to introduce students to the basic power electronic devices and circuits used to process electrical power.
The laboratory brings together both aspects of the above modules. |

Summary of Intended Learning Outcomes
By the end of the course, the student should be able to: Electrical Machines: Determine the behaviour of three phase machines and power systems in per-unit or absolute terms and convert freely between either medium. Describe, analyse, and solve graphically the steady state operation of synchronous motors and generators.
Power Electronics: Be aware of the main power electronic devices currently available, and their basic operating characteristics from a user¿s viewpoint. Be able to perform calculations on ideal DC chopper circuits. Have a good understanding of single and three phase thyristor controlled rectifier circuits, and be able to draw their output waveforms and perform simple calculations on them. Understand the reasons for using HVDC power transmission, and be able to perform power flow calculations. Be able to explain the operation of single and three phase inverter circuits, and draw their output waveforms.
Power laboratory: Work safely and competently with mains voltage power equipment and rotating electrical machines. Design a system consisting of rotating electrical machines and power electronic equipment to produce electricity at the correct voltage and frequency. |
