Communication technology used in protection of power systems and in substations



Unit title Unit code Requirement type Description
EEEN60311 Pre-Requisite Compulsory


Aims of the course unit:

This unit aims to introduce the classical and advanced operating principles and main features of various types of relays and protection schemes. It provides the knowledge necessary to understand how these relays and schemes are applied to the protection of plant and systems including transmission, distribution and industrial networks and rotating machines.

It describes the methods and instrumentation used for testing of protective devices and complex protective solutions involving a larger number of protective devices.

Finally, the unit introduces the principles of wide area monitoring, protection and control, which are underpinned by the availability of high speed information and communication technology in protection schemes.


Learning outcomes

Students will be able to:

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

ILO1 Summarise the requirement for fast and reliable power system protection and the main components that are part of a modern protection system.

ILO2 Describe the operating principles of a range of protection schemes including overcurrent, distance, busbar, transformer and motor protection

ILO3 Evaluate the design of protection systems for use on a transmission, distribution or industrial network through the use of hand calculations, using standard software packages such as Excel or through specialist software including PSCAD

ILO4 Describe how modern information and communication systems are transforming the way protection is applied to the power system and responding to the challenges of increased levels of embedded generation / HVDC.
