Alternating-current and direction-current (AC-DC) integrated power supply system and DC power supply cabinet

Abstract

The invention discloses an alternating-current and direction-current (AC-DC) integrated power supply system, which comprises an AC power distribution unit, an AC uninterruptible power supply (UPS) system, a charging module, a battery pack, a communication power supply and a monitoring system. The AC power distribution unit is connected with two AC mains supplies; when the AC mains supplies are turned on, the AC mains supplies supply power to the AC UPS system and the charging module through the AC power distribution unit, and the charging module converts the AC mains supplies into a stable DC power supply and outputs the stable DC power supply to the battery pack and the communication power supply; and when the AC mains supplies are turned off, the battery pack supplies power to the communication power supply and the AC UPS system. The monitoring system comprises monitoring software, the monitoring software comprises a main interface and an independent sub-interface, and the main interface is used for displaying the main wiring diagram of the intelligent integrated power supply system and displaying the operating conditions and the information of functional units of an intelligent integrated power supply in real time. The invention further discloses a DC power supply cabinet adopting the AC-DC integrated power supply system.

Description

technical field [0001] The present invention relates to power supply equipment, in particular to an AC-DC integrated power supply system and a DC power supply cabinet using the AC-DC integrated power supply system. Background technique [0002] The station power supply is the basis for the safe operation of the substation. The improvement of the comprehensive automation level of substations and the use of a large number of unattended stations require a corresponding increase in the automation control level of station power supplies. [0003] Traditional substation power supply decentralized design, independent group screen, including AC system, DC system, communication power system, UPS (uninterruptible power supply), etc., each subsystem is produced, installed, and debugged by different suppliers, and is managed by different professionals Personnel management and maintenance. The main problems with this model are: [0004] 1) The degree of automatic control of station po...

AI Technical Summary

Problems solved by technology

[0004] 1) The degree of automatic control of station power supply is low, the communication rules of subsystems provided by different suppliers are generally incompatible, it is difficult to realize network management, and the system lacks a comprehensive analysis platform, which restricts the improvement of management efficiency;

[0005] 2) Repeated investment, station power resources cannot be shared, and each subsystem needs an independent power supply;

[0006] 3) There are a lot of operation and maintenance personnel, each station is managed by different professionals for power distribution, and the communication power supply, UPS, etc. are not included in the strict inspection scope of the substation, and the reliability cannot be guaranteed
