This unit of study covers applied and creative knowledge and skills in the areas of electric energy systems protection and communication. The unit is delivered in two parts:
Part A - Protection: Part A investigates the planning, design and operation of protection systems in electrical generation, transmission and distribution systems. Design standards and performance requirements are critically reviewed and different principles and types of protection systems (over-current, impedance, differential, backup, fuses) are hypothesised. Application of protection systems to generators, motors, transmission lines, transformers, busbars, and distribution networks will be diagnosed. Sources of overvoltages and lightning impact on transmission and distribution networks will be debated. Surge propagation theory, circuit interruption theory and operation of instrument transformers will be assessed.
Part B - Communication: Part B deconstructs the relationships between power system automation, control, and communication concepts and technologies, as integral elements of a state of the art power system network, i.e. a smart grid informed by the IEC 61850 protocol. Power system automation, protection and control concepts will be explored with examples from real world applications such as SCADA technologies. Part B will also revise the communication technologies, network topologies, and standardization efforts in the power systems communication arena, and analyse the effectiveness of the relevant standards, communication architectures, and protocols developed for use in these networks. Security concerns in power system communication networks will be outlined and the importance of developing and maintaining a secure network against cyber-attacks will be further substantiated.
