Further information on descriptions 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.

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.

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.
