The module extends knowledge and skills for electrical power system analysis. It introduces modelling and simulation techniques used in electrical power systems to ensure safe design and reliable operation. Simulation of electrical power flows and short circuit calculations in networks is investigated using numerical modelling, power system analysis software and a power system simulator. 

1. Describe the equivalent circuits models of key power system components
2. Perform steady state power flow calculations.  
3. Use power system analysis software to conduct steady state power flow analysis. 
4. Perform unbalanced fault calculations 
5. Describe security and transient stability considerations of electrical power systems. 

The module will be delivered in the Autumn semester through a blend of on-campus face-to-face classes (tutorials, feedback sessions), online learning material, and guided study. Each week, there will be a face-face 2-hour session with short lectures and examples and a lab session to develop skills on the use power system analysis software. 

Visits to a local electricity distribution and transmission substation will take place between weeks 6-8 and students will get experience in using a power system simulator between weeks 7-9. 

In addition to developing your problem solving, critical thinking, reflection and communication skills that link with the graduate attributes of ‘Collaboration and communication’ and ‘Independent and critical thinking’, the module will support you in developing skills in:  

• Modelling and analysis of electrical power systems. 
• Conduct steady state power flow studies. 
• Conduct unbalanced fault calculations. 
• Use of commercial software for power system analysis and validate with manual calculations.

There are two assessments on the module:

One summative assessment will be an individual Exam (50%) (LO 1(p),3,4,5(p) and 6(p)). 

Graduate attributes of Problem solving, Critical Thinking and Communication are developed here  

Feedback on the summative exam will be provided in the form of generic cohort feedback and your individual grade.  

Formative opportunities will be provided through tutorials.   

Feedback on formative work will be verbal in class.  

The second summative assessment will be a lab assignment (50%) on Use of Power Flow Analysis software and a Power System Simulator for load flow analysis (LO 1(p) and 2).  

Graduate attributes of Problem-solving, Critical thinking, Digital Literacy, Reflection, and Communication are developed here. 

Written feedback on the marked lab assignment will be provided individually through Ultra alongside generic cohort feedback and your individual mark.   

Formative opportunities will be provided through computer lab assignments and Ultra discussion boards. 

Feedback on formative work will be verbal in class. 

Note (p) denotes partial coverage of LO.

THE OPPORTUNITY FOR REASSESSMENT IN THIS MODULE:

The opportunity for reassessment in this module will be set at component level. The remit of the reassessment will be set by the module leader mapped against the module learning outcomes.    

Opportunities for re-assessment is only permitted provided you have not failed more credit than in the resit rule adopted by your programme. If the amount of credit you have failed is more than permitted by the relevant resit rule, you may be permitted to repeat study if you are within the threshold set for the Repeat rule adopted by your programme.  You will be notified of your eligibility to resit/repeat any modules after the Examining Board in the Summer period.

All resit assessments will be held in the Resit Examination period, prior to the start of the following academic session.

• Modelling electrical power systems for steady state analysis  
• Bus admittance matrix formulation 
• Gauss-Seidel and Newton-Raphson methods for solving power flow equations 
• Calculation of unsymmetrical faults: single line to ground fault, double line to ground fault, line to line fault. 
• Power system security and stability concepts 
• Power system analysis software for load flow analysis
