Title:
POWER SUPPLY METHOD, APPARATUS AND SYSTEM FOR RAIL TRANSIT
Document Type and Number:
WIPO Patent Application WO/2019/174416
Kind Code:
A1
Abstract:
The present invention relates to a power supply method, apparatus and system for rail transit. The power supply system for rail transit comprises a UPS and an alternating-current power distribution cabinet. The UPS comprises a cross station-dedicated adjustable inverter. The UPS and the alternating-current power distribution cabinet are disposed in a same station. The output power of the UPS is greater than or equal to the sum of the power required by the station and the power required by a neighboring station of the station. The cross station-dedicated adjustable inverter is used for outputting electric energy to the alternating-current power distribution cabinet by means of a first inversion channel and a second inversion channel, the output voltage of the second inversion channel being greater than that of the first inversion channel. The alternating-current power distribution cabinet is used for transmitting the electric energy output from the first inversion channel to weak current systems in the station and transmitting the electric energy output from the second inversion channel to the neighboring station of the station. The present invention can implement the reduction of the number of power supply devices on a power supply line, improves the security and stability of power supply, saves resources, and reduces the costs for construction and maintenance.
