| Summary: | This paper compares train energy consumption of hybrid diesel-electric multiple unit (HDEMU) to hydrogen fuel-cell multiple unit (HFCMU). In the simulation, the parameters of the DMU HŽ7022 train were used for the train model created in Matlab/Simulink environment. Since the train is powered by three diesel engines in original design, it was hybridized by removing one engine and adding a battery and a supercapacitor. For comparison, a train model was made with fuel cells that have rated power of two existing diesel engines, and it was hybridized with a battery and a supercapacitor, as in the simulation with the hybridization of diesel engines. The results are presented by comparing energy consumption for both trains. In addition, voltages, electric current values and power loads of power sources are shown. As the sustainability of the system, the SOC (State of Charge) values of both the battery and the supercapacitor are presented. |
