Aims
This module is intended to achieve the following programme aims within the field of Electrical Engineering:
To introduce the three-phase power system and transmission lines.
To enhance knowledge and understanding of the broad scientific and technological principles underpinning operation of rotating electrical machinery and transformers.
To develop understanding of the steady-state operating principles of single-phase, three-phase transformers, DC and AC rotating machines.
To rehearse practical skills in the use of mathematical methods for modelling and analysing electric machines and power systems.
To introduce the use of electric machines in clean energy applications such as Hydro power plants, pumped storage systems and Wind farms.

Outline Syllabus:
Fundamentals of electromagnetism:
Force and torque in magnetic field, induced electromotive force. Inductance and magnetic circuits: self-inductance, mutual and leakage inductance; magnetic circuits and reluctance of the magnetic path, B-H curve of magnetic material, cores with air-gap. Induced electromotive force: induction in stationary systems with time varying fields and in systems with movable parts in time dependent and time independent fields. Losses in ferromagnetic materials.
Electric machines and clean energy:
Electromechanical energy conversion: motoring and generating, time-domain modelling, torque and average torque, types of machines, rotating field. Steady-state analysis of dc machines: types, circuits and equations, speed-torque curve. Steady-state analysis of induction machines: operating principle, equivalent circuit, phasor diagram, torque speed curve, losses and efficiency. Steady-state analysis of synchronous motors/generators: operating principles, active and reactive power, phasor diagrams, equivalent circuits, power and torque versus load angle curves. The use of synchronous generators and induction generators in Hydro and wind energy converters.
Electric power systems:
Impedance drop, voltage drop and voltage regulation. Modelling of power system components: load, transmission lines, cables and transformers. Per unit system. Symmetrical component theory, symmetrical impedance networks. Symmetrical and asymmetrical short circuit analysis.

M1 Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering.
M2 Formulate and analyse complex problems to reach substantiated conclusions. This will involve evaluating available data using first principles of mathematics, statistics, natural science and engineering principles, and using engineering judgment to work with information that may be uncertain or incomplete, discussing the limitations of the techniques employed.
M3 Select and apply appropriate computational and analytical techniques to model complex problems, discussing the limitations of the techniques employed.
M4 Select and critically evaluate technical literature and other sources of information to solve complex problems.
