Abstract

The invention relates to the technical field of electric power control, in particular to a through-type in-phase traction power supply system, a traction substation and a power supply control method thereof, aiming at solving the technical problem of how to reliably supply power to an electric locomotive. To this end, the present invention provides a traction substation comprising a plurality of electrical energy conversion devices. In particular, the electric energy conversion device comprises a single-phase transformer and an electric energy converter, The high-voltage winding of each single-phase transformer is respectively connected with two different phase wires in a preset power network, the low-voltage winding of each single-phase transformer is connected with an input side port ofa corresponding electric energy converter, and the output side port of each electric energy converter is respectively connected with a preset contact line and a preset rail. Based on the structure, the traction substation can also rely on other electric energy conversion devices to continuously supply a continuous supply voltage to the catenary with a constant voltage amplitude and phase when partof the electric energy conversion device fails. The power supply system of the present invention comprises the traction substation.

Description

technical field

[0001] The invention relates to the technical field of power control, in particular to a through-type in-phase traction power supply system, a traction substation and a power supply control method thereof. Background technique

[0002] The electrified railway traction power supply system refers to the power supply system that supplies electric locomotive traction power, mainly composed of traction substations and catenary. The traction substation converts the three-phase alternating current sent by the power plant through the high-voltage transmission line into the current and voltage suitable for the electric locomotive, and then sends it to the catenary, and then the catenary supplies power to the locomotive.

[0003] In order to meet the single-phase power supply requirements of the railway system, the electrified railway traction power supply system usually supplies power to electric locomotives in different power supply sections by means of phase-splitti...
