Abstract
U ovom diplomskom radu analizirana je diferencijalna zaštita transformatora, s posebnim naglaskom na problematiku kada su transformatori povezani u paralelni pogon. Diferencijalna zaštita predstavlja temeljnu relejnu zaštitu energetskog (mrežnog) transformatora koja odgovara isključivo na kvarove koji se događaju unutar njezine zaštitne zone. Kroz rad su objašnjene osnovne karakteristike diferencijalne zaštite, posebnosti diferencijalne zaštite transformatora te fenomeni inrusha i simpatetskog inrusha. Simulacije su izvršene koristeći programski paket DIgSILENT (Power Factory) u kojem su prikazani rezultati simulacija za različite scenarije. Spomenuti scenariji prikazuju unutarnje i vanjske kvarove te postupak energizacije transformatora. Dobiveni rezultati simulacija potvrdili su važnost pravilnog podešenja diferencijalne zaštite transformatora u paralelnom pogonu te prikazali mogućnosti i potencijalne poteškoće pri njezinom korištenju.
Abstract (english)
This thesis analyses the differential protection of transformers with special emphasis on problems that may occur when transformers are connected in parallel. Differential protection represents the basic relay protection of the power transformer which, responds only to the malfunctions that occur within its protection zone. The thesis also explains the basic characteristics of differential protection, the peculiarities of transformer differential protection, and the phenomena of inrush and sympathetic inrush. The simulations were performed using the DIgSILENT software package (Power Factory) in which the simulation results for different situations are presented. The mentioned situations show internal and external malfunctions and the process of energizing the transformer. The obtained results of the simulations confirmed the importance of the correct settings of the differential protection of the transformer in parallel operation and presented the possibilities and potential difficulties in its use.
