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60 s或180 s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90 s左右,建议发车时间间隔为180 s.

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 braking energy efficiency based on the departure time interval. Results through MATLAB SIMULINK simulation 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 impulse voltage is lower and power consumption by traction substations is also lower. Considering the vehicle return time being about 90 s at terminal or regional stations of Shenzhen Metro Line One, it is recommended that the departure time interval is adjusted to 180 s.
