The invention relates to a low-emission safe and reliable rail transit system power supply method, a device and a system. The invention relates to a method, equipment and a system for applying a fuel cell power generation technology to an electrified rail transit power supply system and an electrified trolley bus power supply system, and provides a method for establishing a distributed power station based on the fuel cell technology to supply power to an electrified line or a station. For an existing non-electrified line, the distributed power stations based on the fuel cell technology are arranged along the line, and electrification transformation is rapidly and conveniently achieved. A plurality of or a plurality of groups of fuel cells are combined in series and in parallel, a converter is used for boosting, an energy storage device with a certain capacity is configured, and an output end is connected with the converter, so that electric power with power, voltage class and power supply system required by a traction power grid is provided, and meanwhile, a plurality of sets of redundant power generation technologies can be provided, or other power generation technologies can be combined, or redundant power supply with the power grid can be provided, and the traction electricity demand of an electrified line is met.

    本发明涉及低排放安全可靠的轨道交通系统供电方法、设备和系统。本发明涉及一种燃料电池发电技术应用于电气化轨道交通供电系统和电气化无轨电车供电系统的方法、设备和系统,提供一种基于燃料电池技术建立分布式电站为电气化线路或车站供电。对于现有非电气化线路,通过沿线布置基于燃料电池技术的分布式电站,快速方便实现电气化改造。通过多个或多组燃料电池的串并组合,再由变流装置进行升压,同时配置一定容量的蓄能装置,及输出端接变流装置,提供牵引电网所需要的功率、电压等级、供电制式的电力,同时可以提供多套冗余、或复合其他发电技术、或与电网冗余供电,满足电气化线路牵引用电需求。
