摘要:
以接触网间歇式供电电容储能车辆储能系统运行工况的建模方法为研究对象，对接触网间歇式供电电容储能式有轨电车运行过程建立多质点模型，并对以超级电容为基础的车载储能系统建立其数学模型。对储能车辆进行区间线路仿真，得到超级电容功率曲线及SOC(荷电状态)曲线，并将多质点模型与单质点模型下的仿真结果进行对比。对车载储能系统运行工况进行分析，验证了列车多质点动力学模型对储能系统的能量计算具有更高的精确性。
Abstracts:
Taking the operational condition modeling of vehicle capacitive energy storage system by catenary intermittent power supply as the research object, a multi-particle model is established for the operation process of tramcar capacitive energy storage by catenary intermittent power supply, and the mathematical model of the onboard energy storage system based on supercapacitor is built. Through route interval simulation of energy storage vehicle, the supercapacitor power curve and SOC (state of charge) curve are obtained, the simulation results of multi-particle model and single-particle model are compared. By analyzing the operational conditions of the on-board energy storage system, the multi-particle model is verified to have higher accurate energy calculation for the energy storage system.
