Problems solved by technology

For railway projects in complex and dangerous mountainous areas, the lines have many ups and downs, the steep slopes are long, and the slope difference is usually large, and various types of climbing peak power and regenerative energy frequently appear alternately; This further exacerbates the problem of the traction power supply system, especially the large fluctuation of the traction network voltage caused by the impact of forward and reverse power flows.

Abstract

The invention relates to an integrated traction power supply system architecture based on source network load storage. The integrated traction power supply system architecture at least comprises a traction power supply system, a rail transit vehicle, an energy storage module and a measurement and control module. The traction power supply system is used for supplying power to a rail transit vehicle; the rail transit vehicle consumes electric energy or feeds back the electric energy through regenerative braking; and the measurement and control module makes the energy storage module store the feedback electric energy when the rail transit vehicle feeds back the electric energy. According to the embodiment of the invention, problems of forward and reverse tidal current impacts, regenerated energy recycling and instability of a traction network in the prior art can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of electrified railways, in particular to an integrated traction power supply system architecture based on source, network, load, and storage. Background technique [0002] As the main line railway extends to complex and dangerous mountainous areas, there are often many long ramps, high ratio of bridges and tunnels, and frequent regenerative braking of trains during the operation of trains. For railway projects in complex and dangerous mountainous areas, the lines have many ups and downs, the steep slopes are long, and the slope difference is usually large, and various types of climbing peak power and regenerative energy frequently appear alternately; This further exacerbates the traction power supply system, especially the problem that the traction network voltage fluctuates greatly due to the impact of forward and reverse power flows. Contents of the invention [0003] In order to solve the abo...
