Subject Description

On completion students should; be familiar with the concepts and terminology of electrical power engineering; be able to describe the construction of common electrical and mechanical power sources; understand the operating characteristics of common electrical and mechanical devices used for motive power; be able to construct time and frequency - domain models of simple electrical, mechanical, pneumatic and hydraulic engineering components and systems; be able to compute time-and frequency-domain responses of linear dynamical systems.

Topics covered include; Electric power systems: d. c. and a. c. power supplies and distribution systems; inverters, transformers and rectifiers; principles and operation of single and multi-phase a. c. machines, induction motors, and d. c. machines; solid-state control of machines, Mechanical power systems: Principles and operation of electro-hydraulic and electro-pneumatic servo valves and actuators, System modelling: Unified approach to modelling electrical, mechanical and thermal systems: 'across' and 'through' variables; equilibrium, constraint and constitutive equations; block diagrams, transfer function and state-space representations, System responses: Computation of transient and steady-state time responses and harmonic frequency responses; Bode plots. Relationship between response characteristics and pole-zero locations. Use of Matlab for system response calculations.
