Abstract
Krajem 2008. godine u Hrvatskoj je uspostavljen Sustav za lociranje mjesta udara munja kao dio europskog sustava LINET. Sustav za lociranje munja predstavlja programsku podršku za arhiviranje i primjenu podataka sustava LINET o udarima munja na području Hrvatske. Opisan je način podešenja i djelovanje uređaja distantne relejne zaštite, čiji podaci o vremenu i mjestu nastanka kvara se koreliraju s podacima o udarima munja. Vremenska korelacija kvarova i udara munje pokazala je uređaji relejne zaštite detektiraju kvar najčešće u vremenskom periodu od 8 ms do 13 ms nakon udara munje, što odgovara mjerenjem utvrđenom vremenu pobude uređaja relejne zaštite. Prostorna korelacija je pokazala da srednja vrijednost razlike udaljenosti mjesta kvara određenog lokatorom kvara i mjesta udara munje iznosi 1,37 % ukupne duljine promatranog prijenosnog voda, što je zadovoljavajući rezultat obzirom da na točnost rezultata funkcije lokatora kvara, kao i na točnost lociranja mjesta udara munja, utječe više različitih faktora. Pokazano je da vremenska korelacija može pružiti informaciju o uzroku nastanka kvara, a podatak o mjestu udara munje može poslužiti kao orijentacija o mjestu nastanka kvara. Rezultati usporedbi pokazuju učinkovitost primjene podataka Sustava za lociranje munja i povezivanja sa sustavom vođenja elektroenergetskog sustava, kroz korelaciju podataka.
Abstract (english)
Lightning Location System has been established in Croatia at the end of year 2008 as a part of European LINET system. Lightning Location System is software for archiving and application of LINET system data on lightning strikes in Croatia. The parameter setting and the operation of distant relay devices were described, and data on fault time and location were correlated with lightning strike data. The temporal correlation of the faults and lightning strikes revealed that relay protection devices detect the fault on the protected transmission line, generally from 8 ms to 13 ms after lightning stroke, which corresponds to the results of measurements of the relay protection device's pickup time. The spatial correlation of the faults on transmission line and lightning strikes indicated that the median value of differences between the fault location and the lightning strike location is 1,37 percent of total transmission line length of the observed line. This is a satisfactory result considering that the accuracy of the fault locator results, as well as the strike location accuracy, is affected by several factors. It has been indicated that temporal correlation can provide the information on the fault causes and the data on lightning strike location can serve as information on the fault location. The results of the comparison indicate the efficiency of the Lightning Location System application and its implementation within the power system operation and control by correlation of data.
