The invention belongs to the technical field of electrified railways, and particularly relates to a train-ground collaborative railway traction emergency power supply system and a control method. On the basis of the existing tractive power supply system, through a train-ground integrated cooperative power supply link, sustainable new energy, stored energy, available electric energy of adjacent fault-free sections and other schedulable resources along the railway can be aggregated, and an emergency guarantee power supply independent of an external power grid and a substation is provided for the tractive power supply system; the practical problems that in an existing traction emergency power supply technical scheme, dependence on an external power grid is high, the vehicle-mounted capacity is limited, toxic gas is generated through diesel internal combustion and the like are solved, and potential risk losses caused by insufficient emergency capacity of a conventional system can be effectively avoided. And meanwhile, the railway energy response state can be flexibly converted from a traditional network following type to an emergency network construction type, and the independent island operation capability can be provided for a fault section within the jurisdiction range.
本发明属于电气化铁路技术领域,尤其是涉及一种车地协同型铁路牵引应急供电系统及控制方法。本发明在既有牵引供电系统基础上,通过车地一体化协同供电环节,能够聚合铁路沿线可持续新能源、储能、相邻无故障区段可用电能等可调度性资源,为牵引供电系统提供了独立于外部电网和变电所的应急保障供电电源,克服了既有牵引应急供电技术方案中对外部电网强依赖、车载容量受限、柴油内燃产生有毒气体等实际问题,能够有效避免常规系统应急能力不足造成的潜在风险损失;同时本发明能够实现铁路能量响应状态由传统跟网型向应急构网型方向的灵活转变,可为管辖范围内的故障区段提供独立孤岛运行能力。
