Learning outcomes:
After successfully completing this module, students will have acquired a basic understanding of the physical and engineering operating principles of the equipment used in power supply networks. They will understand the structure of equivalent networks, know how to derive equivalent network models from the physical behaviour of real networks, and understand their significance when analysing power supply networks. They will understand the importance of and be able to apply mathematical techniques relevant in the power supply sector (e.g. modal transformation). Students will also have learned about the steady-state behaviour of symmetric and asymmetric electric power networks and will have acquired the methods to compute the steady-state status of the network particularly when line faults arise. This will involve, in particular, a deeper understanding of how to apply the method of symmetric components.
