Objectives The student is expected to gain an understanding of the modelling and analysis of polyphase transformers, synchronous and asynchronous machines. The student is also expected to become familiar with the practices employed in the electrical power industry and with the requirements for the application and control of industrial drives.
Synopsis Transformers: modelling for two and three windings, polyphase, Scott and Le Blanc connections, voltage regulation, parallel operation and load sharing, harmonics, sequence networks. Induction machine: analysis of machine performance based on equivalent circuits and circle diagram. Speed control, starting and protection. Synchronous machine: two-axis models, torque and power characteristics, performance diagrams, transient behaviour, stability under dynamic and steady state conditions.
Assessment Examination: 80% + Assignments: 10% + Laboratory: 10%
