20.500.12556/DKUM-21414 TEHNIČNO-TEHNOLOŠKI ELEMENTI ŽELEZNIŠKE PROGE V FUNKCIJI RACIONALNE RABE ENERGIJE ZA VLEKO VLAKOV TECHNICAL AND TECHNOLOGICAL ELEMENTS OF THE RAILWAY LINE IN A FUNCTION OF RATIONAL ENERGY CONSUMPTION FOR TRAIN HAULAGE V magistrskem delu je na podlagi teoretičnega raziskovanja vplivov tehnično-tehnoloških parametrov železniške proge na rabo energije za vleko vlakov analizirana poraba energije v treh najpomembnejših segmentih železniškega sistema: gradbenih parametrov proge, prometno-tehnoloških elementov ter dinamike vožnje vlaka. Gradbene parametre proge predstavljajo nagib proge, krožni lok proge in predor. V prometno-tehnoloških elementih glavno vlogo predstavlja vodenje prometa vlakov v postajnem območju in na odprti progi ter glede na vrsto SV naprav. Dinamika vožnje vlaka predstavlja suprastrukturne elemente ter skupek infrastrukturnih in prometno-tehnoloških vplivov na vožnjo vlaka. Največji prihranki energije v železniškem prometu se dosegajo z izbiro ustreznih gradbenih parametrov proge. Z optimalnim odvijanjem prometa vlakov lahko dosežemo več ciljev, najpomembnejši so zmanjšanje porabe energije za vleko vlakov, skrajšanje voznih časov vlakov ter ugoden vpliv na dinamiko vožnje vlaka. Tovorni vlaki so največji porabniki energije, zato se največ energije lahko prihrani v tem segmentu vlakov. Določene rezerve prihranka energije obstajajo tudi v segmentu potniških vlakov. Učinkovito varčevanje oz. racionalna raba energije za vleko vlakov je potrebna v vseh segmentih železniškega prometa. S programskim simulacijskim orodjem VIST so na podlagi analiz in izvedenih simulacij vožnje vlaka pod različnimi pogoji podani predlogi racionalne rabe energije z vidika železniške infrastrukture, suprastrukture in vodenja prometa vlakov. Simulacijsko orodje omogoča teoretično analizo porabe energije med vožnje vlaka v realni situaciji ter na podlagi določenih predpostavk. Podani predlogi racionalne rabe energije so implementirani v primerjalno študijo nove železniške povezave Ljubljana-letališče Jožeta Pučnika-Jesenice. Na podlagi izračunane porabe energije za vleko vlakov je bila z vidika racionalne rabe energije izbrana najugodnejša varianta nove proge. The current paper presents a theoretical effects of technical and technological parameters of the railway line on energy consumption for train haulage. Energy consumption has been analyzed in three most important segments of the railway system: construction parameters of the line, traffic and technological elements and dynamics train movement. Construction parameters are represented by the slope of the line, line curve and tunnel. An important role in the traffic and technological elements is train movement in the station area and on the open line, based on a signal and safety devices. The dynamics train movement presents suprastructure elements and jointly infrastructure and traffic and technological effects on the train movement. The mayor energy savings in the railway traffic can be achieved by selecting appropriate construction parameters of line. By optimal traffic management can be reached more aims; the most important are reduction of energy consumption for train haulage, shorter driving times and favorable impact on dynamics train movement. Goods trains are the biggest consumers of energy, so the most energy can be saved in this segment of trains. Energy savings can also be achieved in the segment of passenger trains. Effective energy consumption and rational energy savings for train haulage is necessary in all segments of the railway traffic. By the software simulation tool VIST different analysis and simulations of train movement can be made under different conditions. On the base of simulations some proposals for rational energy consumption were given from an aspect of railway infrastructure, suprastructure and traffic management. Simulation tool allows a theoretical analysis of energy consumption at train movement in a real situation and with predefined asumptions. The proposals for rational energy consumption are implemented in a case study of new railway line Ljubljana-airport-Jesenice. On the base of energy calculations for each variant, the most advantageous variant of the new railway line was chosen from the aspect of energy consumption. železniška infrastruktura vodenje prometa vlakov dinamika vožnje vlaka upor proge poraba energije energija za vleko vlakov railway infrastructure traffic management dynamics train movement railway line resistance energy consumption train haulage energy true true false [K.
