Abstract

S obzirom da je generator jedan od najznačajnijih elementa u elektroenergetskom sustavu, od iznimne je važnosti dobro ga zaštiti u pogonu od raznoraznih smetnji i kvarova. U termoelektrani se najčešće spaja u bloku s transformatorom. Upravo zbog toga je potrebno ozbiljno pristupiti analizi sustava zaštite navedenih elemenata.
U ovom je radu kroz primjer Petrokemije Kutina prikazan izbor i podešenje zaštite generatora i blok transformatora. Posebna pozornost je posvećena načinu konfiguriranja zaštitnih funkcija u numeričkom releju, te su predložena konkretna podešenja odabranih zaštitnih funkcija.

Abstract (english)

Since the generator is one of the most significant elements in the power system, it is extremely important to well protect its operation from various disturbances and equipment failures. In thermal power plant it is usually connected in block with a transformer. This is why it is necessary to seriously approach protection system analysis of mentioned elements.
In the paper, through example of Petrokemija Kutina, choice and protection setting of generator and block transformer is shown. Special attention is paid to a protective function configuration in numerical relay, and specific settings of the selected protection functions have been proposed.
