Unit Information

The aim of this unit is to understand the requirements of modern power networks in terms of energy conversion through power electronics and machines and demonstrate the benefit of full system integration.

This unit covers the requirements of modern power networks in terms of energy conversion through power electronics and machines. It discusses the basics of power semiconductor devices, converter topologies ranging from the switched-mode power supplies to MW-rated power converters in transmission systems, analysis of power systems and the synchronous machines that connect to these systems.

The unit will use a range of end-to-end case studies to allow students to experience first-hand and explore the design considerations and trade-offs that engineers must balance when prototyping innovative, efficient and integrated solutions to real-world problems.

The unit provides the core taught element of the programme specific content for the year for the Mechanical and Electrical Engineering programme and is deliberate designed for these students with this in mind. This is supplemented with the individual research project in TB2

An overview of content

This unit covers the requirements of modern power networks in terms of energy conversion through power electronics and machines. It discusses the basics of power semiconductor devices, converter topologies ranging from the switched-mode power supplies to MW-rated power converters in transmission systems, analysis of power systems and the synchronous machines that connect to these systems.

How will students, personally, be different as a result of the unit

Students will be able to select and use modelling techniques at an appropriate level to explore various operating scenarios and device a range of outcomes related to the design and operation of power electric systems and drives. They will be able to use these tool to explore previous unseen power networks and a creative, enquiring and independent manner.

Learning Outcomes

  1. Describe the fundamental elements (and their roles) of an electric drive system
  2. Explain the basic operation of power semiconductor devices as a switch and the role of diodes in providing current flow and commutation paths
  3. Implement and appraise, using appropriate modelling techniques over a range of applications and scale
  4. Calculate how power flow is managed in a multi-phase energy system, including stability under transient conditions and fault and unbalanced conditions
  5. Design and evaluate a full end-to-end electric drive using appropriate topologies for the various elements of the system
  6. Explore the impact of electro-mechanical drive integration at the system (application) level

How you will learn

Teaching will be delivered through a combination of synchronous sessions (including simulation laboratories) and asynchronous activities, including video lectures, activities supported by self-directed exercises and by problem sheets.

How you will be assessed

Tasks which help you learn and prepare you for summative tasks (formative):

You will be given a range of activity sheets (with solutions provided after a week) that help you develop your understanding of the taught concepts and use these to test your ability to use the software tools to consolidate this understanding and explore these further where appropriate.

Tasks which count towards your unit mark (summative):

There will be two summative assessments that will be used to measure the degree to which you have

  1. used the simulation tools to allow exploration and implementation of the design techniques for a power electronic converter and machine as a drive (30% Coursework, issued mid TB, deadline end TB) - ILO 3,5 and 6
  2. developed an ability to use the taught content to specify/design/analyse electric power supply and drive systems either in their entirety or as subsystems (70% exam, TB1) - ILO 1,2, 4, 5

When assessment does not go to plan

For students engaging in a capped re-assessment, a single summative exam based assessment will be set that tests all ILOs for a threshold pass but be capped of offering a graded outcome for non-simulation ILOs.

For students engaging in a first attempt (or uncapped assessment) either or both of the original individual assessment elements (coursework or exam) that was failed/missed originally will be required to be re-assessed. The re-assessment exam paper will be the same one used to test students for capped re-assessment.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENG30013).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the University Workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. For appropriate assessments, if you have self-certificated your absence, you will normally be required to complete it the next time it runs (for assessments at the end of TB1 and TB2 this is usually in the next re-assessment period).
The Board of Examiners will take into account any exceptional circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
