主 讲 人
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.
