| Popis: | Naziv ovog završnog rada je “Relejna zaštita energetskih transformatora u TS Vrboran“. U radu je prezentirana relejna zaštita energetskog transformatora uz sažet prikaz teoretskih podloga korištenih funkcija relejne zaštite. Na primjeru transformatora smještenih u TS Vrboran izvršeni su proračuni podešenja funkcija relejne zaštite integriranih u numeričkim uređajima zaštite, koji se koriste za štićenje transformatora u slučajevima kod nastupa međufaznog te dozemnog kratkog spoja. Pri proračunima su uzeti u obzir svi osnovni kriteriji kvalitetnog rada relejne zaštite, a dobiveni podaci koriste se kao podloga za ispravno podešenje numeričkih uređaja zaštite transformatora. Bitno je naglasiti da kvalitetan rad sustava relejne zaštite doprinosi kvaliteti funkcioniranja EES-a u cjelini. The title of this final paper is the “Relay protection of power transformer in TS Vrboran”. The relay protection of power transformer is presented in this paper together with the concise review of theoretical basis of the used relay protection functions. On the example of the particular transformer in TS Vrboran the calculations for the adjustment of the relay protection function were performed. These are integrated in the numerical protection devices that are used to protect the transformer in case of an phase to phase or a ground fault short circuit. During the calculations all the basic criteria for quality work of the relay protection were taken into consideration, and the data obtained were used as a basis for properly setting numerical transformer protection devices. It should be noted that the proper functioning of the relay protection system contributes to the quality functioning of the EES in general. |
