Problems solved by technology

However, these solutions still have some shortcomings: shaft end power generation can only be generated when the vehicle is running, wind power and photovoltaic power generation are limited by the environment, and the power generation is unstable
Therefore, a single technical solution cannot achieve continuous and stable power supply output, and several solutions need to be combined to complement each other

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 and figure 2 As shown, the power generation system for the multi-source railway wagon vehicle of the present invention includes:

[0031] The first power generation device 1 is a shaft-end generator, which is installed at the end of the axle. The motor rotor of the shaft-end generator is connected to the axle, without conversion through the axle box and pulley, and the axle rotates to directly drive the generator to generate electricity; The generator is the most stable and reliable, not affected by the weather environment, and can supply power as long as the vehicle is running.

[0032] One or more auxiliary power generating devices installed on the vehicle body to generate electricity;

[0033] The power conversion and management device is used to convert and manage the power generated by the first power ...

Abstract

The invention discloses a power generation system and a power generation method for a multi-source system railway freight vehicle. The power generation system comprises a first power generation device which is an axle end power generator mounted at the end part of an axle, and further comprises more than one auxiliary power generation device mounted on a vehicle body and used for generating power; and a power supply conversion and management device used for converting and managing the electric power generated by the first power generation device and the auxiliary power generation device and completing power supply output to an application object. The power generation method is a method based on the power generation system. The system has the advantages of simple structure, easy realization, continuous and stable output, multi-mode compatibility and the like.

Description

technical field [0001] The invention mainly relates to the technical field of rail transportation, in particular to a power generation system and method for a multi-source railway freight car vehicle. Background technique [0002] In order to solve the power consumption problem of railway vehicles (here refers to trailers without power units), early passenger vehicles adopted a shaft-driven DC generator solution, that is, the generator was hung on the vehicle chassis or bogie frame, and the axles rotated when the train was running. The generator is driven by a pulley to generate electricity. However, due to the differences in bogie structures between passenger cars and trucks, the generator cannot be installed and used on trucks. The bogie for passenger cars generally consists of four parts: wheel-to-axle box, bolster spring, frame, and braking device. The structure of the bogie is simple, only one series of springs are suspended, and it adopts the "three big parts" struct...
