The module extends knowledge and skills for electrical power system analysis and introduce students to high voltage laboratory environment and test techniques. It introduces modelling, simulation and testing methods used in electrical power systems to ensure safe and reliable operation. Simulation of electrical power flows in networks is investigated using numerical modelling and power system analysis software. High voltage lab testing methods are introduced and demonstrated in a lab environment.  

1. Perform steady state power flow calculations.  
2. Use power system analysis software to conduct steady state power flow analysis. 
3. Perform unbalanced fault calculations 
4. Describe security and transient stability considerations of electrical power systems. 
5. Describe high voltage testing techniques 
6. Design, construct and analyse high voltage test and measurement 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. 

Computer lab sessions will be held from week 5-10 to practice use of software for numerical modelling and power system analysis.  

High voltage lab demonstration will be conducted between weeks 4-8.  

Visits to a local distribution and transmission substation and to the lightning lab will take place between weeks 6-8 

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. 

• Analysis and design of high voltage power supplies. 

• Perform and analyse high voltage tests and measurements to international standards. 

There are three assessments on the module: 

One summative assessment will be an individual Exam (70%) (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 coursework assignment (15%) on Electrical Power 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 coursework 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. 

The third summative assessment will be a High Voltage Lab demonstration assignment (15%) (LO 5(p) and 6(p)). 

Graduate attributes of Problem-solving, Critical thinking, Reflection, designs and application of national/international standards, and Communication are developed here 

Written feedback on the marked coursework assignment will be provided individually and your individual mark. 

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 

• High voltage testing and measurements: Introduction to International standard for High Voltage Testing 

• Generation and measurement techniques for direct, alternating and impulse voltages (cascade d.c. multipliers, cascade transformers, Marx generators; resistive, capacitive and mixed dividers); generation of and measurement techniques for high magnitude impulse currents (capacitive generator, Rogowski coil, tubular current shunt).
