Study on Optimization of Energy Saving Operation of High-speed Railway
Energy consumption of high speed railway mainly involves three influencing factors, infrastructure (Train attributes and Line properties), and transport organization and driver control mode respectively. This paper mainly studies the influence of driver control mode on train energy consumption. Considering track gradient and speed limit, the paper proposes energy-saving mode at three phases of motoring, running and braking. Finally, the feasibility of energy operation model has been verified by computer simulation under certain operating conditions of the train, lines, and established train group planning. Meanwhile, the paper makes the comparison between practical and the results of computer simulation and shows that the energy consumption of proposed energy saving mode is 9.48% less than the driver's control.
