摘要
通过分析城轨车辆在电气制动过程中发生再生制动及电阻制动的条件,并且根据车辆的编组、线路、载重、运行策略、运行图、牵引供电等基本因素,在单车牵引计算模型及多车运行的牵引供电网络模型的基础上,建立了城轨车辆电气制动能量分布模型,并进行了实例仿真计算。仿真计算结果表明,在相同的线路及车辆条件下,车辆发车间隔为180s时,再生制动能量占总电气制动能量的比率为80.1%,随着发车间隔的增大,该比率逐渐减小;当发车间隔在900s时,电气制动能量绝大多数消耗在制动电阻上。该制动能量分布模型可以为各种城市轨道交通制动能量回收方法提供理论支持,还可以为各种制动能量回收装置提供装置选型等方面的依据。
By analyzing conditions that urban rail vehicles in the traction power supply network occur the regenerative braking or resistor braking in electric braking process,and depending on the grouping of vehicles,lines,load,run strategy,operation plans,traction power supply and other basic conditions,based on single vehicle computing model and multi-vehicles power supply network model,electric braking energy distribution model were established and simulation were carried out.Simulation results showed that in the same line and vehicle conditions,the ratio of regenerative braking energy occupying the total braking was 80.1% when vehicle interval was 180 seconds,with the interval increases the ratio decrease.When the interval was 900 seconds the electric braking energy was almost consumed by braking resistor.The braking energy distribution model can provide theoretical support for a variety of urban rail transit braking energy recovery methods,but also offer foundation for selection of braking energy recovery device.
