| Description:
| Aims: To introduce and analyse electrical machines and power electronic systems for high-power applications; such as, industrial and traction drives, small-scale power generation, and power system control. To examine the operation, characteristics, and capabilities of commonly used systems and their control methods. Learning Outcomes: After taking this unit the student should be able to: (i) Appreciate the steady state and dynamic characteristics of induction machines when used for medium- and high-power motoring and generating duties. Understand the development of synchronous machine models using reference-frame theory, and the use of such models in performance prediction and for control. (ii) Appreciate the characteristics and capabilities of high-power power-semiconductor devices, power conversion circuits, and converter control methods; understand selection criteria for matching power converter types and control methods with applications; and be able to undertake provisional performance assessments using specimen applications. Skills: Application of the information, techniques and methods discussed in the lectures, to the proposal of, and the carrying through of, appropriate so-lutions to engineering problems in high-power power-electronics and machines. Taught, facilitated and tested. Content: Induction machines: operation as motors and generators; space harmonic effects, and dynamic model. Large synchronous machines; operating characteristics, dynamic model, and introduction to vector control. AC-DC power conversion: thyristor converters, rectification, inversion, HVDC and drive applications, harmonic analysis. DC-AC power conversion: inverter types, managing output waveform distortion; and applications in drives, reactive-power compensation and power-flow control. High-power power-semiconductor devices: characteristics, performance and application requirements. |
