Introduction of IEC61850 standard has provided many new opportunities for improving protection and automation functions with a substation. This new standard and related communication infrastructure has the capability to facilitate a smart substation with a new paradigm for providing protection functions. One of the possible improvements in the protection functionality can be implementation of a multi-type IED within a substation. The multi-type protection IED indicates a new concept that allows remote changes to protection IEDs. This method presents an effective measure for enhancing protection reliability in the event of a merging unit and IED faults. At the same time, it also has the potential to decrease protection costs by consolidating backup protection functions. This talk will start with an overview of the IEC61850 standard for substation automation and protection. This will be followed by a description of possible improvements that can be achieved within the new environment using IEC61850. Laboratory implementation and test results for the multi-type IED will be presented. Testing showed that a multi-type IED can take over the functioning of a failed primary IED without much delay.
Biography Tarlochan S. Sidhu received the B.E (Hons.) degree from Thapar Institute of Engineering and Technology, Patiala, India, in 1979 and the M.Sc. and Ph.D degrees from the University of Saskatchewan, Saskatoon, SK, Canada in 1985 and 1989, respectively. He worked for the Regional Computer Center, Chandigarh, India, Punjab State Electricity Board, India, and Bell-Northern Research Ltd., Ottawa, Canada. From July 1990 to June 2002, he was with the Department of Electrical Engineering, University of Saskatchewan, where he served as Professor and Graduate Chairman of the Department. He is currently Professor and Chair of the Electrical and Computer Engineering Department at the University of Western Ontario, London, Ontario, Canada. He is also the NSERC/Hydro One Networks Senior Industrial Research Chair in Power Systems Engineering. He regularly contributes to the activities of IEEE Power Systems Relaying Committee and served as Chair of its Relaying Practices Subcommittee from 2007-9. He has published more than 200 papers in various journals and conferences, and some of these papers have won major awards. He is regularly invited to give lectures/tutorials around the world on the subject of power system protection, automation and monitoring. He has served regularly as a consultant to power system industries both nationally and internationally. More than 50 graduate students have completed their thesis work under his supervision/co-supervision. He serves as the Editor-in-Chief of the International Journal of Emerging Electric Power Systems, an Editor of the IEEE Trans. On Power Delivery and that of IEEE Power Engineering Letters. He is on the editorial boards of Electric Power Systems Research, Electric Power Machines and Components, and Relay (China). Tarlochan is a Fellow of the Institution of Engineers (India), a Fellow of the Institution of Engineering and Technology (U.K), a Fellow of the Engineering Institution of Canada, a Fellow of the Canadian Academy of Engineering and a Fellow of the Institute of Electrical and Electronics Engineers (USA).
