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

The course unit unit aims to: Develop an understanding of the structure and operating principles of an electrical power system and its components.

ILO 1 - Develop an understanding of Power Systems and High Voltage equipment and materials, capturing their risk of failure, recovery, and sustainability properties.

ILO 2 - Formulate steady-state models of overhead lines, cables and transformers and use their single-line diagrams to understand and study their behaviour (and failure mechanisms) within the system as a whole.

ILO 3 - Use per-unit system and phase diagrams to represent power system networks and understand their performance and real-life applications.

ILO 4 - Conduct fault current calculations under symmetric fault situations and identify short circuit levels within a power system.

ILO 5 - Reason using abstract rather than physical quantities.

ILO 6 - Evaluate power flow calculations analytically using an industrial standards software package (IPSA+).

ILO 7 - Critically assess the operation and design of a simple power system and its role in sustainability.
