Title:
TRAIN TRACTION POWER SUPPLY DEVICE AND SYSTEM, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/010499
Kind Code:
A1
Abstract:
A train traction power supply device, comprising a diode rectifier set, a four-quadrant converter set, and a central controller. The diode rectifier set, the four-quadrant converter set, and the central controller are connected in parallel to an alternating current power network and a direct current contact network. The central controller is connected to the four-quadrant converter set. The central controller is used for adjusting the output current of the four-quadrant converter set according to voltage and current of the alternating current power network and the voltage of the direct current contact network. The central controller is further used for receiving an inversion instruction comprising a de-icing current value sent by a de-icing control device, and switching the train traction power supply device to an inversion working position according to the inversion instruction, so that an energy cycle is formed among the four-quadrant converter unit of the train traction power supply device, a zone to be de-iced of the direct current contact network, the diode rectifier set of the train traction power supply device adjacent to the zone to be de-iced, and the alternating current power network corresponding to the zone to be de-iced. Also provided are a train traction power supply system and a control method therefor. According to the train traction power supply device and system, and the control method, the functions of the train traction power supply system are enriched.
