Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their analytical skills, background understanding of the subject, problem solving skills as well as identify any transferable skills that are relevant to the power industry.


Thus, the summative assessment for this module consists of:

• 
  2 hours exam that accounts for 80% of the assessment. The exam paper will be designed to test students’ theoretical knowledge as well as problem solving skills related to the learning outcomes of this module.
  


• 
  Coursework: MATLAB/Simulink Design Exercise that accounts for 20%. This allows students to apply their knowledge to a practical design problem.
  

Module aims

• introduce the key principles of electrical machines, power generation and transmission
• introduce the power distribution systems and interconnected grid systems.
• To provide practical design experience through MATLAB/Simlink simulation

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to: include regular lectures from Week 1 to 10. These lectures will include the problem solving sessions (30 hours: 3 hours lecture/tutorial per week for 10 weeks). Three hours of revision will take place in Week 11. Lecture notes will be provided and students are expected to do independent learning in addition to attending lectures and tutorials. In addition, a MATLAB/Simulink exercise is included on microgrid power system design.

 

The learning and teaching methods include:

• 3 hours lecture per week x 10 weeks which includes class discussion and problem solving sessions.


• 3 hours in-class revision in Week 11.


• MATLAB/Simulink design exercise.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
