Abstract

Električni tramvaji su jedan od standardnih oblika javnog prijevoza. Za razliku od većine drugih električnih vozila, karakteriziraju ih veliki iznosi struje i gradijenta struje, pogotovo prilikom ubrzanja. Iz tog razloga se javlja potreba za sekundarnim izvorom energije koji bi zadovoljio potrebe energije s ciljem povećanja energetske učinkovitosti, smanjenja ukupne potrošene energije iz mreže te smanjenja vršnih vrijednosti struje. Kao sekundarni izvor koristi se superkondenzator. U radu je opisan hibridni energetski sustav napojna mreža/superkondenzator te je razvijen algoritam upravljanja. Analiziran je rad algoritma za dvije tramvajske linije različitog vertikalnog profila rute. Topologija modela i algoritam upravljanja modelirani su i simulirani u programskom paketu MATLAB/Simulink.

Abstract (english)

Electric trams are one of the standard forms of public transport. Unlike most other electric vehicles, they are characterized by large amounts of current and current gradients, especially when accelerating. Therefore, a secondary energy source is required that would meet energy demands in order to increase energy efficiency, reduce total energy grid consumption and reduce peak electricity values. A supercapacitor is used as a secondary source. The paper describes a hybrid energy system power grid / supercapacitor and a control algorithm is developed. The efficiency of the algorithm was analyzed for two tram lines of different vertical profile of the route. The model topology and control algorithm were modeled and simulated in the MATLAB / Simulink software package.
