城市轨道车辆频繁的制动过程产生了大量的电能。该部分能量在不满足反馈电网条件时常常通过制动电阻的方式消耗,导致了能量的浪费。结合动力学理论和供电网络关系分析了城市轨道交通车辆制动能量产生的特性及约束条件,提出一种基于车载的脱离电网的制动能量回收方法,并通过制动能量回收实验系统,进行了实验研究。结果表明,利用该系统可以对城市轨道车辆制动能量进行有效的回收。

This paper is an attempt to address the waste of the braking energy such as occurs when a lot of electrical energy produced by the frequent braking process of the urban railway vehicles is often consumed in the form of breaking resistor due to the failure to fulfill the requirements of braking energy feedback to power grid.The paper describes the analysis of the characteristics and restrained conditions of producing braking energy of the urban railway vehicle by combining vehicle dynamics with power supply,proposes a novel recovery method of braking energy free from power grid on the urban railway vehicle and introduces the experimental research depending on an experimental system of braking energy recovery.The results show that the system is capable of an effective recovery of braking energy.
