BEng Electrical and Electronic Engineering

This unit will cover the following:

Part 1: Fundamentals of Electrical Energy & Power System Equipment

1. Review of fundamental background for electrical energy systems:

• Introduction to electrical power systems and materials (capturing also their risk of failure, recovery, and sustainability properties).
• Basic design and equivalent circuits for Switchgear, Transformers, Lines and Cables.
• Vectors in Power Systems, impedance, real and reactive power.
• Example class on equivalent circuit models of components and relevant numerical calculations, including phasors.

Part 2: Introduction to Power System Analysis & Symmetrical Fault Calculations

1. Introduction to Power System Analysis (PSA):

• Per-Unit system (definition, choice of base quantities, equivalent circuits). 
• Formulation of power flow problem and power transfer capability (bus quantities, direction of power flow, transmission of real and reactive power).
• Basic techniques to solve power flow problem (analytical and iterative methods).
• Example class on per unit 2-bus power flow calculation.

2. Introduction to short-circuit faults and fault current calculations:

• Symmetrical faults.
• Example class: Symmetrical fault and short circuit level calculations.

Lab: Performing a Power Flow Network Analysis. A simplified case of real-world network analysis based on IPSA+ software.

The unit aims to provide students with a comprehensive understanding of electrical power systems, focusing on their structure, components, and operating principles.

Students will:

• Explore the design and modelling of key components such as switchgear, transformers, lines, and cables.
• Learn to create equivalent circuit models and perform power flow calculations using the per-unit system. 
• Cover power flow problem-solving techniques and introduces fault analysis and short-circuit calculations. 
• Gain practical skills, including the use of industrial software for power flow calculations, will be developed alongside intellectual skills in abstract reasoning and system analysis.

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

ILO 1: Apply abstract reasoning in power system analysis.

ILO 2: Perform symmetric fault current calculations to determine short-circuit levels and explain their significance for power network operation

ILO 3: Use per-unit system and phase diagrams to analyse power networks’ performance and implement them in real-word problems.

ILO 4: Analyse power flow using industrial software.

ILO 5: Describe the fundamentals of power systems, high-voltage equipment, and explain their operation, failure mechanisms and risks, and their sustainability.

ILO 6: Formulate steady-state models of overhead lines, cables and transformers and use their single line diagrams to describe and study their operation within the power system.

ILO 7: Assess simple power system design and its sustainability role.

10 credit Course Units should normally consist of 100 hours of teaching activities. This includes the time spent undertaking assessments, and the time spent revising or preparing for them.
