Module overview:

Secondary Systems Module 1

This module begins by defining secondary systems and looking generally at the environmental, operation and maintenance, economic and ergonomic requirements and electromagnetic compatibility. The first systems considered are the LVAC and DC auxiliary supply systems. The source and performance requirements for the LVAC and the battery type and performance requirements for the DC system are presented. Next, the role of the protection system and the methods of detecting faults are explained. The different types of protection used for overhead lines, transformers, busbars etc and the use of circuit breaker fail protection are explained. The module concludes with metering and monitoring including tariff metering, fault recorders, fault locators and sequence of event recorders.

Secondary Systems Module 2

This module covers manual control of the substation including interlocking, synchronising, conventional and computer control systems and point on wave control. Then various automatic control systems are looked at including auto reclose, auto close, operational tripping, automatic tap change control, automatic reactive control, frequency control and load control. The next topic is communications both within the substation and outside of it including the media used, multiplexing and digital hierarchies. Virtually all protection, control and communications equipment are digital these days so there is a brief explanation of IEC61850. The module concludes by looking at the physical and cyber security systems employed in substations.

John FinnPresenter: John Finn

John Finn worked initially in the Electricity Supply industry in the UK in protection, operation and maintenance and system studies. He then joined private industry working with contractors on power station and substation projects in the UK and overseas at voltages up to 500kV and as diverse as the initial 400kV supergrid for China Light and Power to project managing the power supplies for the Channel Tunnel between England and France. In his role as an in-house engineering consultant with Siemens in the UK he was involved in developing the onshore and offshore substation designs associated with offshore wind farms. He has been involved in CIGRE as Area Advisor on Substation concepts from 2002 to 2006 and convenor of working groups on “standardisation and innovation” and “guidelines for offshore substations”. He received the Technical Committee award for contributions to Study Committee B3 in 2006 and the Distinguished Member award in 2008. He was the coordinating author for the CIGRE Green Book on Substations and is currently the Secretary for the CIGRE UK National Committee
