Abstract

U radu je opisan osnovni princip djelovanja elektromehaničkog distantnog releja te primjena modernih izvedbi numeričkih distantnih releja u komunikacijskim shemama zaštite prijenosnog voda. Nabrojani su glavni uvjeti u kojima će relej pravilno raditi te njegove radne karakteristike, koje se podešavaju s obzirom na konfiguraciju mreže. Detaljno su prikazane zone štićenja distantne zaštite te relativne vrijednosti koje se u praksi najčešće koriste. Na kraju je opisan tijek izvođenja za oba oblika zaštite, s komunikacijom i bez nje, te ukratko opisana logika djelovanja nekoliko distantnih zaštitnih shema.

Abstract (english)

This paper describes the basic physical operation principle of the electromechanical relay and his application in modern performance of numerical distance relays in communication schemes for transmission line protection. This includes the main conditions, in which the relay is working properly, and operating characteristic which is set according to the network configuration. Also, are given details about distance protecting areas and relative values that are commonly used in practice. At the end is described time flow for both forms of protection, with communication and without it, and briefly presented the working logic for several distance protection scheme.
