Abstract
Ovaj rad analizira i predlaže optimalna podešenja distantne zaštite dijela prijenosne mreže sa značajnim razlikama u duljinama vodova, s naglaskom na zaštitu dugačkog prijenosnog voda Đakovo 2 – Našice i kratkog prijenosnog voda Našice – Cementara. Korišten je stvarni model mreže 110 kV u okolini TS Našice, a rezultati su dobiveni simulacijama kvarova provedenim u programskom paketu DIgSILENT. Posebna pažnja posvećena je analizi ponašanja releja REL670, smještenog u TS Đakovo 2, koji mora pružiti selektivnu zaštitu oba voda. Korekcije u podešenjima bile su nužne zbog preklapanja zona zaštite između releja smještenog u TS Đakovo 2 i releja 7SA87 u TS Našice, uslijed kvarova na dalekovodu Našice – Cementara. Optimizacija podešenja rezultirala je poboljšanom selektivnošću i izbjegavanjem preklapanja zona, uz očuvanje stabilnosti i pouzdanosti zaštitnog sustava. Zaključeno je da prilagodba relejnih postavki omogućuje postizanje ravnoteže između brzine reakcije i selektivnosti, što je ključno za stabilnost prijenosne mreže u uvjetima sa značajnim razlikama u duljinama vodova.
Abstract (english)
This paper analyzes and proposes the optimal settings of distance protection for a section of the transmission network with significant differences in line lengths, with a focus on the protection of the long transmission line Đakovo 2 – Našice and the short transmission line Našice – Cementara. A real model of the 110 kV network in the vicinity of the Našice substation was used, and the results were obtained through fault simulations carried out in the DIgSILENT software package. Special attention was given to the behavior of the REL670 relay, located in the Đakovo 2 substation, which is responsible for providing selective protection for both lines. Adjustments to the relay settings were necessary due to the overlap of protection zones between the relay located in Đakovo 2 and the 7SA87 relay in the Našice substation, caused by faults on the Našice – Cementara transmission line. Optimizing the settings resulted in improved selectivity and the elimination of zone overlap, while maintaining the stability and reliability of the protection system. It was concluded that the adaptation of relay settings allows for achieving a balance between speed of response and selectivity, which is crucial for the stability of the transmission network in conditions with significant differences in line lengths.
