Analiza razmer v elektroenergetskem sistemu ob prekinitvi vodnika

PEČJAK, BORUT (author), Mihalič, Rafael (mentor), Ažbe, Valentin (co-mentor)

Diplomsko delo opisuje problematiko okvar, ki se najpogosteje pojavijo v elektroenergetskem omrežju in značilnosti le teh. Opisana je tudi rešitev, ko pride do pretrganja vodnika na daljnovodu, in sicer zaščita z zaščitnim sistemom Lisa. Sprva so predstavljene vse vrste okvar, do katerih lahko pride v elektroenergetskem omrežju, in okvare, do katerih lahko pride zaradi notranjih ali zunanjih vplivov. V nadaljevanju se osredotočimo na opis in delovanje zaščitnega sistema Lisa ter izvedbo zaščitnega sistema Lisa na daljnovodu 20 kVRTP Ilirska Bistrica TP Sviščaki 1. V zaključnem delu so prikazane izpeljave in izračuni na primeru, ko pride do pretrganja vodnika.

Abstract

This thesis describes the problem of malfunctions, that most commonly appear in electromagnetic networks and their properties. Additionally, the solution of powerline conductor breakage using protective system Lisa is described. The introduction starts with the presentation of all possible malfunction types, which can occur in the electromagnetic network, caused by internal or external factors. Afterwards, it focuses on the description and functioning of the protective system Lisa. Furthermore, it explains the execution and usage of the system on the powerline 20kV RTP Ilirska BistricaTP Sviščaki 1. It concludes with derivations and calculations of an example of conductor breakage.
