Analysis of Index System for High-speed Train Operation Energy-Saving Evaluation

The composition of energy consumption of high-speed train operation, influencing factors and weights of index are analyzed. Taking the operational energy consumption of CRH380B as the control target, the index system and methods for high-speed train operation energy-saving evaluation are proposed by establishing the relationship between traction energy consumption and index factor sensitivity based on index factors. The energy-saving measures of weight reduction and drag reduction for high-speed train operating at 400 km/h are analyzed and the energy-saving effect of specific route during operation is verified.
