Title:
ENERGY COORDINATION SYSTEM FOR ELECTRIFIED RAILWAY
Document Type and Number:
WIPO Patent Application WO/2021/003799
Kind Code:
A1
Abstract:
Provided is an energy coordination system for an electrified railway. The system comprises: a traction network, a high-voltage cabinet, and a power assembly, wherein one end of the high-voltage cabinet is connected to the traction network, and the other end thereof is connected to the power assembly; the high-voltage cabinet is used for realizing the turning on and off of a high-voltage side, voltage and current detection, and a protective function; the power assembly comprises a transformer, a pulse width modulation (PWM) converter and an energy storage module; the PWM converter is located between the energy storage module and the transformer; the PWM converter controls the charge/discharge voltage and current of the energy storage module; and the energy storage module operates in an energy storage mode or an energy release mode according to a change in a network voltage value. In the present invention, according to characteristics of difficult lines such as a long large slope and a long large tunnel, the technical characteristics of a traction network, an energy storage element and a PWM converter are specifically used properly, such that the recycling and reusing of energy are realized, the running performance of a train is maintained, and when a remote power supply fault occurs in the traction network, stored energy can be used for nearby emergency power supply, so that the train is driven away from a dangerous road section and waits for rescue.
