Research on Energy Consumption Model of Railway Locomotive

Based on analyzing the energy consumption model of railway locomotive in China and abroad,taking transitional trains on mixed transport of freight and passenger line,beginning from microcosmic view of locomotive energy consumption,train operation environment was settled and energy consumption model of railway locomotive was established by using relative principles of train operation calculation.The conversion coefficient of energy consumption for traction has been taken into the model to calculate the macroscopic locomotive energy consumption though microscopic numerical calculation method.The model could be used for calculating energy consumption of both passenger trains and freight trains.Unit comprehensive energy consumption of locomotive is calculated by using weighted average method according to locomotive proportion and transportation workload.Through calculating, the fuel consumption value of diesel locomotive and the electric consumption value of electric locomotive are close to actual statistics data.
