摘要
为了更好地提高城市轨道交通车辆的能源利用率,本文基于深圳地铁一号线车辆和路线的真实数据,建立了同一供电臂下车辆质量及其力学模型、列车牵引与制动功率模型、列车牵引力及制动力模型,以及列车供电网络模型,基于发车时间间隔,对车辆再生制动节能进行研究.经MATLAB中SIMULINK仿真运算,得到以下结论:同一供电臂下,两车追踪时间为60s或180s时,能量利用率较高,且对接触网的冲击电压较低,牵引变电所消耗功率较低.综合考虑深圳地铁一号线终点站或区域站车辆折返时间为90s左右,建议发车时间间隔为180s.
Using real data of Shenzhen Metro Line One, a train quality and mechanics model, a train traction and braking power model, a train traction and braking force model and a train power supply network model were established to study vehicle regenerative braki departure time interval. Results through MATLAB SIMULINK simul ng ati energy efficiency based on the on calculations were derived as follows： on the same power arm, when two vehicles＇ track time is 60 s or 180 s, energy efficiency is higher, catenary Considering the Metro Line One, impulse vehicle voltage is lower and power consumption by traction substations is also lower. return time being about 90 s at terminal or regional stations of Shenzhen it is recommended that the departure time interval is adjusted to 180 s.
