Analysis on Energy Efficiency and Rapidity of High-speed Train Operation

Abstract

This paper aims to improve the energy efficiency of train operation and realize the rapidity of train operation under the condition of safe driving. First, describe the difference between energy efficiency and energy consumption and the importance of energy efficiency for train energy-saving operation. Then, build the mathematical model of energy efficiency calculation of high-speed train operation, propose a hierarchical calculation and simulation method of energy consumption and energy efficiency of high-speed train operation. Taking CRH380CL train as an example, build simulation experiments with two aspects of energy-saving and rapid train operation to analyze the influence of idle running on braking energy consumption under the constraints of station spacing, and propose a concept of dynamic recovery and utilization of regenerative energy. This paper is helpful to further study the comprehensive optimization of high-speed train behavior.
