Abstract
Distantna zaštita temelj je zaštite visokonaponskih vodova u prijenosnoj mreži napona 400, 220 i 110 kV od pojave različitih vrsta kvarova. Njena uloga u elektroenergetskom sustava dana je u uvodnom poglavlju ovog diplomskog rada te posljedice koje ista ima u djelovanju na osnovne funkcije rada sustava. Poznavanje uvjeta koje distantni relej treba ispunjavati u mreži od bitnog je značaja, a vrijedi spomenuti brzinu djelovanja, selektivnost, osjetiljivost te pričuvno štićenje. Drugo poglavlje opisuje osnove implementacije same distantne relejne zaštite u sustavu, njena osnovna načela, načine priključka na visokonaponski prijenosni vod putem strujnih i naponski transformatora te različite vrste proradnih karakteristika koje takav relej može imati. U trećem poglavlju objašnjena je struktura mikroprocesorskih elektroničkih krugova na kojima se temelji suvremeni Siemensov Spirotec 7SA6 distantni relej te su detaljno analizirane karakteristike tog uređaja uz opise svih njegovih funkcija u mreži. U četvrtom poglavlju razmatrana je principna aplikacija ATP-EMTP softvera koji se u modernom vremenu koristi za različite vrste analize elektroenergetske mreže, a posebice za analizu različitih vrsta kvarova u mreži (kratki spojevi, udari munje i sl.). Osnovne podloge korištenja i načini međusobne komunikacije programskih modula također su pojašnjeni. Peto poglavlje opisuje samu primjenu programskog softvera ATP-EMTP i to konkretno simulacijom različitih vrsta kratkih spojeva u visokonaponskoj prijenosnoj mreži (jednopolni, dvopolni i tropolni kratki spoj) te analizom proradne distantne zaštite s poligonalnom proradnom karakteristikom s tri zone štićenja u odnosu na te kvarove. Kratki spojevi simulirani su na različitim mjestima na štićenoj dionici voda te su prikazane trajektorije mjerenih impedancija u sve tri faze u R-X koordinatnoj ravnini (Argandov dijagram).
Abstract (english)
Distance protection is the basic electrical protection of high voltage lines in transmission grid such as 400, 220 and 110 kV grids. It's main function in power system is given in the introductory part of this master's thesis and so are it's exploitation consequences on system operation. Knowledge of operational conditions which distance protection relay has to fulfill is of significant value which are speed of tripping, selectivity, sensitivity and back-up protection. Second chapter describes distance protection implementation's basics to the system, it's main principles, connection of relays and high voltage lines using current and voltage transformers and different tripping characteristics which relay can possess. In the third chapter microprocessor electronic circuits on which modern Siemens Spirotec 7SA6 relay is being based on are explained and the detailed analysis of device's characteristics and functions are given. In the fourth chapter the principles of ATP-EMTP software are considered which is suitable power system analysis program especially for analysis of different power system failures (short circuits, lightning strikes etc.). The connection methods between different program modules are also described. Fifth chapter describes the application of ATP-EMTP software by simulating different power system failures in high voltage grid (single pole, bipolar, three pole short circuit) and analysis of distance protection relay tripping with poligonal tripping characteristics operating on three proctection zones reacting to those system failures is presented. Failures are simulated in different positions of the high voltage lines and the trajectories of measured impedances in all three phases are shown in R-X coordinate system (Argand's diagram).
