Course overview
This course provides a general introduction to power engineering. It focuses mainly on the principles, modelling and analysis of DC and AC electrical machines and transformers. The principles of electric drives and power systems are also discussed.
Course learning outcomes
- Analyse single and three-phase AC power circuits using phasors, to determine real and reactive power flow and demonstrate power-factor correction
- Analyse the performance of transformers and explain concepts of the back-EMF equation, saturation and iron losses
- Analyse the performance of a DC motor or generator using its equivalent circuit and explain its construction and operating principles, including back-EMF and efficiency
- Describe the basic principles of DC and AC electric machines and variable-speed drives
- Analyse the performance of an induction machine using its equivalent circuit
- Explain the operating principles, construction and the concept of slip
- Explain the operating principles, construction and performance of synchronous machines
- Describe the major components of an electric power system
- Develop practical skills through performing tests on AC circuits, transformers and electrical machines in the laboratory to determine their parameters and performance Analyse and discuss the experimental results in reports
