中文摘要: 城轨交通列车应急牵引是指车辆在失去外部供电条件下,依靠车载蓄电池驱动列车运行至站台等安全区域,是列车新型高效故障导向安全技术之一。然而受蓄电池容量限制,列车运行速度低、距离短,如何通过优化节能控制提高列车应急牵引运行距离、缩短旅客疏散时间是亟待解决的技术难题。应急牵引系统工作模式存在诸多特殊性,如变流器处于自然冷却状态等,因此系统工作特性分析是优化控制研究的基础。此外,系统优化控制涉及电机动态效率优化、蓄电池能量优化分配等诸多技术难题,相关理论问题尚未得到深入研究。本课题拟对城轨列车蓄电池应急牵引优化控制技术展开研究,首先建立系统机、电、热一体化分析模型,对应急牵引系统工作模式及特性进行深入分析,在此基础上研究电机动态效率优化控制及蓄电池能量非线性规划优化分配方法,进而分别从单位距离能耗最低及时间最短等优化目标入手展开系统优化控制策略研究。相关研究成果将为新一代城轨车辆研制提供理论依据。

英文摘要: When the urban mass transit vehicle lost external power supply, the train can be propelled by on board storage battery to the next station. Such novel storage battery emergency traction scheme plays an important role in the emergency rescue. However, the operation speed and distance in emergency traction mode is restricted by the capacity of on board battery. Optimization and energy conservation control scheme of the system should be developed for the improvement of emergency rescue performance, which are the key challenges for the battery emergency traction scheme. The traction system characteristic in emergency traction mode is rather different to the normal mode due to that the cooling fan of the traction inverter will stop running in emergency mode. Furthermore, the optimization control scheme should be developed on the basis of analysis of system characteristic. The corresponding theoretical issues and control scheme, which includes dynamic efficiency optimization control and nonlinear programming of the battery energy, haven't been thoroughly researched. This project is subject to research of the optimization control of storage battery emergency traction of urban mass transit vehicle. Firstly, coupled electrical-thermal-mechanical analysis model is developed to analyze the system characteristic in emergenc
