Aims of Module
To provide the student with the ability to analyse the performance and operation of ac machines and drive systems, and to apply simulation techniques to aid this analysis.

Learning Outcomes for Module
On completion of this module, students are expected to be able to:
1 Apply 2-axis analysis to the performance of 3-phase synchronous and induction motors.
2 Understand and analyse the operation of AC drive systems as applied to 3-phase induction motors.
3 Utilise simulation tools to analyse the transient performance of AC machines.

Indicative Module Content
Salient pole synchronous machines. Principles of operation, application and analysis. Two-axis analysis. Generalised machine theory. Application to the transient analysis of both synchronous and induction machines. AC drives: induction motor operation on variable-voltage variable frequency supplies, principles of self-commutated, variable-frequency inverter operation, control of output voltage, frequency and harmonics. Principles of braking and regeneration, slip energy recovery, stator voltage control, cycloconverters. Introduction to flux-vector control of ac machines Matlab and Simulink analysis of ac machines and drive systems in steady-state and transient operation.

Module Delivery
This is a lecture-based course supplemented with tutorial sessions, laboratory work and student-centred learning.
