Aims & Learning Objectives:
Aims: To provide a fundamental understanding of the structure, operation and analysis of a modern power system.
Objectives:
After successfully completing this unit students will be able to: identify factors affecting the pricing of electricity, describe the advantages of interconnected networks, describe and analyse transformers, explain the principles of switching, explain and analyse the operation of a generator and its control systems, predict the stability of a generator under varying system conditions, explain and apply methods of load flow analysis, perform balanced and unbalanced fault calculations, analyse and apply transmission line models, make simple settings calculations for overcurrent, distance and differential protection.
