High-speed rail power system based on solid hydrogen

Abstract

The invention discloses a high-speed rail power system based on solid hydrogen. The high-speed rail power system comprises a hydrogen generating device, and the hydrogen generating device is providedwith an inlet end and an outlet end. The inlet end of the hydrogen generating device communicates in parallel with a solid hydrogen tank and a water tank, and a fuel cell system is disposed at the outlet end of the hydrogen generating device in a communication mode. The fuel cell system communicates with an air generating device, one end of the fuel cell system is connected with a heat exchanger,and the heat exchanger is provided with a thermal inlet end and a cold outlet end. According to the high-speed rail power system based on the solid hydrogen, the control over the hydrogen amount and generated energy is realized through a monitoring unit under normal temperatures and pressure, the hydrogen produced is instantly consumed, extremely high safety controllability is achieved, the numberof ordinary power plants can be reduced, and environmental pollution is reduced; fuel cells generate direct currents, one part of the direct currents is used for providing kinetic energy to high-speed rails, and the other part is used for supplying power to the load through an inverter to AC220V / 380V; and water produced by the fuel cells passes through a circulating waterway to the water tank, one part of the water is used for reacting with the solid hydrogen, and the other part is used for water supply of high-speed rail water facilities.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a high-speed rail power system based on solid hydrogen. Background technique [0002] At present, the power of high-speed rail is powered by electric locomotives. The electrical energy required by the electric locomotive is supplied by the catenary of the electrified railway power supply system or the third rail for the running electric locomotive. It is a locomotive without its own energy. Electric EMUs rely on externally transmitted electric energy. Electric energy comes from ordinary power plants, and then sent to the catenary through the transformer substation. The pantograph of the locomotive is in contact with the catenary, so as to lead the electric power into the locomotive, and then Then through the transformation, the rectification is sent to the traction motor to drive the EMU. Domestic ordinary power plants mainly use combustibles (such as coal) as fuel to pro...

Problems solved by technology

[0003] However, there are certain problems in the current power system. First, the existing power plants burn non-renewable resources in the process of generating electricity, which not only has low efficiency, but also produces a large amount of pollutants, which seriously pollutes the environment.

Second, there are many ways to obtain hydrogen, mainly focusing on putting the hydrogen produced by spot decomposition and coal decomposition into high-pressure hydrogen storage tanks, but the safety hazards caused by high-pressure hydrogen storage and transportation technologies are currently the biggest The disadvantages of
