Characteristics of fault detection system for smart grid distribution network/Sumaniojo elektros paskirstymo tinklo gedimo vietos nustatymo sistemos charakteristikos

The smart grid is the vision of the electric power network which integrates the electrotechnical, communication and informatics technologies. This integration allows developing new fault location technologies which are based on methods of fast transients analysis. The usage of these methods allows to locate the fault faster and more reliably or to prevent possible faults. The topic explains the structure of the fault location system for the smart electric power distribution network, discusses the challenges of smart grid fault location system and describes the method for one phase to ground fault location which is based on fast transient analysis. Ill. 2, bibl. 13 (in English; abstracts in English and Lithuanian). Sumanusis elektros tinklas--tai elektros tinklas, jungiantis elektrotechnines, rysiu ir informacines technologijas. Siu technologiju integravimas leidzia sukurti naujas elektros tinklo gedimo vietos nustatymo technologijas, pagristas greitu pereinamju vyksmu analizes metodais. Taikant siuos metodus galima greitai ir patikimai nustatyti elektros tinklo gedimo vieta ar isvengti galimu gedimu. Straipsnyje apibudinama sumaniojo elektros paskirstymo tinklo gedimo vietos nustatymo sistemos struktura, aptariami reikalavimai sumaniojo elektros tinklo gedimu nustatymo sistemai, aprasomas vienfazio izemejimo vietos nustatymo metodas, pagrastas greitu pereinamuju vyksmu analize. Il. 2, bibl. 13 (anglu kalba; santraukos anglu ir lietuviu k.).
