Aims

This course unit detail provides the framework for delivery in 2020/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.

The course unit aims to:

  • Prepare students for a career in electrical power engineering. It covers a spectrum of important aspects of electrical power systems analysis and operation
  • Produce graduates with a systematic knowledge and understanding of the mathematics and engineering science required for the analysis of electrical power systems
  • Develop the analytical and practical skills appropriate for a career in electrical power engineering
  • Equip students with the knowledge and skills needed to design and analyse electrical power systems that are fit for purpose, cost effective, compliant with relevant legislation, safety criteria and environmentally sustainable

Learning outcomes

On the successful completion of the course, students will be able to:
