|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 10 (Year 4 Undergraduate)
||Availability||Available to all students
|Summary||This course will develop understanding of fundamental building blocks of a modern electrical power system, ranging from high capacity generation to low power point of use power supplies.
The students gain analysis and skills in three core areas, power systems, electrical machines and power electronics.
Power Electronics: The concept of switch mode power conversion will be developed starting with basic circuits and extended to more complex topologies and functions, including the generation of two and three phase ac waveforms.
Electrical Machines: Transient and variable speed control of synchronous and induction machines will be developed, in the context of generation in power networks and variable speed systems in wind energy. The use of power electronic converters to achieve variable speed control will link into the power electronics aspect of the course. Electro-mechanical and thermal analysis of transients and variable speed will be developed.
Power Systems: This part of the course will consider a number of relevant technical and engineering aspects of operation, control and protection of electrical machines and power supply systems with distributed generation.
A range of case studies will be used to illustrate: how power electronics may be applied to real world applications; control and operation of networks with distributed generation; calculation or estimation of short circuit fault currents and overcurrent protection settings.
1. Introduction to switch mode power conversion.
2. DC/DC Converters (Buck analysis to be covered in detail with introduction to other base topologies).
3. Isolated DC/DC converters
4. DC/AC Converters (Topology and Modulation and Harmonics)
5. Introduction to losses and heatsinking.
1. Variable speed control of induction machines & 4-Q operation.
2. Doubly Fed Induction generators for wind energy.
3. Electromechanical analysis of machine transients.
4. Thermal analysis and machine rating.

6. Duty cycle analysis for different applications.
1. Control Systems and Stability of Synchronous Generators.
2. Operation of Distributed Generators in Power Supply Systems.
3. Balanced Per-Unit Short Circuit Fault Analysis.
4. Power System Protection Equipment.
5. Overcurrent Protection: Operate Currents, Device Characteristics, Time and Amplitude Discrimination.
6. Overcurrent Protection Case Study.
