Abstract

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.

Description

technical field

[0001] The invention belongs to the field of rail transit, and in particular relates to a method, device and system for applying fuel cell power generation technology to an electrified rail transit power supply system and an electrified trolleybus power supply system. Background technique

[0002] In order to reduce harmful and greenhouse gas emissions, it is necessary to reduce dependence on fossil energy including oil and coal. Most of China's electricity comes from coal power generation. The use of cleaner energy such as hydrogen, natural gas and other green energy can help achieve the above goals. The power supply system in the field of rail transit, especially the traction power supply system, is relatively independent, and fuel cell technology can be used for power generation, and methods, devices and systems for rail transit system power supply based on fuel cell technology are needed.

[0003] The existing rail transit system power supply system and f...
