高速列车节能优化运行模式研究

Study on Energy-saving and Optimized Operation Mode of High-speed Trains

为实现高速列车正点节能运行的目标,以高速列车牵引计算理论为基础,对"牵引-匀速-惰行-制动"(模式1)和"多次牵引-惰行-制动"(模式2)2种运行模式进行分析比较。考虑高速列车再生制动,建立高速列车运动学方程,给出2种运行模式下高速列车运行时间、运行距离及能耗的微积分计算方法,分别建立满足正点到站的能耗模型,并以北京南—廊坊区段为例,运用MATLAB进行仿真。结果表明,模式1比模式2节能6.67%,研究结果对高速列车采用节能优化的运行模式具有一定的借鉴意义。

In order to achieve the object of being punctual and saving energy among high- speed trains, based on the traction calculation theory of high-speed trains, this paper analyzes and compares 2 operation modes, which are the ＂tracticn-uniform-coasting-braking＂ （Mode 1） and ＂traction repeatedly-coasting-braking＂ （Mode 2）. Through considering regenerative braking of high-speed train, the kinematics equations of high-speed train are established, and the calculus calculation method of operation time, operation distance and energy consumption are given under two operation modes. The energy consumption model which satisfies punctual arrival is constructed respectively, and Beijing South-Langfang section is simulated by using MATLAB as an example. The comparison result shows Mode 1 can save 6.67% energy than mode 2, and the study result has referential meaning in applying the energy-saving and optimized operation mode for high-speed trains.
