Abstract

U radu je opisana primjena podataka o atmosferskim pražnjenjima dobivenih iz sustava za lociranje atmosferskih pražnjenja (SLAP, eng. Lightning Locating System, LLS) u analizi utjecaja udara munja na funkcionalnost željezničke mreže. U drugom poglavlju su ukratko opisani osnovni principi napajanja, uzemljenja i zaštite kontaktne mreže za sustav 25 kV, 50 Hz, koja se odnosi na dio željezničke mreže nad kojom se izvršava analiza. Treće poglavlje sadrži informacije o Sustavu za lociranje munja (SLM, eng. Lightning Location System - LLS) kao dijelu Europskog sustava LINET. Navedene su neke od njegovih mogućnosti u vođenju elektroenergetskog sustava, te je pobliže opisan princip rada sustava. Prikazan je dizajn programske podrške za obradu podataka o atmosferskim pražnjenjima i korelaciju atmosferskih podataka s geografskim podacima (GIS, eng. Geographic Information System) željezničke mreže. Pomoću opisane programske podrške provedena je analiza i korelacija nad stvarnim podacima atmosferskih pražnjenja u razdoblju od 2009. – 2014. godine.

Abstract (english)

The paper describes the application of information on atmospheric discharges from the Lighning Location System (LLS) in the analysis of the impact of lightning strikes on the functionality of the railway network. The basic principles of power supplying, grounding and protection of the contact network for 25 kV, 50 Hz, which covers the rail network over which the analysis is performed, are briefly described in the second section. The third section contains information about the Lightning Location System as part of the European System of LINET, and about its capabilities in managing the electric power system. Design software for processing data on atmospheric discharges and correlation of atmospheric data with geographic information (GIS, eng. Geographic Information System) of the rail network are demonstrated. Using the software, an analysis and correlation of actual data of atmospheric discharges in the period from 2009 - 2014. has been made.
