Evolution of Power System   Protections - Issues to Solve and Challenges





Prof.   Désiré D. Rasolomampionona




Désiré D.   Rasolomampionona  received the Graduate degree from Warsaw   University of Technology, Warsaw, Poland, in 1988, the Ph.D. degree in 1994,   and the Habilitation in 2008. Since 1994, he has been as an Associate Professor   with Warsaw University of Technology. He is currently the Head of the   Division of Electrical Power Apparatus, Protection and Control. He is also   the current IEEE/IA Poland Joint Chapter Chair. His research interests   include the issues of electrical power control and protection, control of the   power system operation, and the use of telecommunications and modern   information technologies in electrical power engineering. Since 2017, prof.   Rasolomampionona is involved in a few scinetific anc technical projects   related to Microgrid implementation and Microgrid Protections.


This lecture is devoted to   the general evolution of power system protections during the last few   decades. A short history of protective relaying is presented at the   beginning. Then a systematic review of the improvements made into the protection   technology is presented in the next part of the lecture. A particular   emphasis was placed in the passage from mechanical, to solid state and modern   protective technologies based on telecommunication applications protective   relaying, the beginning of which is the very old differential relay systems   and pilot relays. Then the conception of adaptive relaying and its   possibility of implementation is presented by showing the different solutions   proposed by different authors. The next part of the lecture is devoted to the   implementation of Wide-Area Monitoring, Protection, and Control, which was   made possible thanks to the introduction of phasor technology in protection   technology. Finally a general presentation of microgrids and the impact of   their implementation on the protection philosophy is presented step by step.   An extensive presentation of this technology is given in the first subsection   of this part, and then the changes to be made to the protective relaying   technology are given in the next subsection. An extensive conclusion of the   whole subjects presented is given at the end of the presentation.
