A Monitoring Redundancy Backup Method for Improving the Reliability of Integrated Power Supply System

Abstract

The invention discloses a method for improving the reliability of a power supply system through monitoring redundant backup. Through the configuration of a redundant backup mechanism of integral power supply monitoring equipment, a redundant backup method of combining manual and automatic operation of the integral power supply monitoring equipment is adopted, and the redundant backup of the backup monitoring equipment on the control monitoring equipment is realized. The method has the advantages that when the control monitoring equipment fails, the backup monitoring equipment carries out redundant backup on the power supply equipment, the normal operation of a monitoring system of the power supply equipment can be ensured, the reliability and the maintainability of the power supply equipment are improved, in addition, an integral main system monitor is connected with a plurality of parallelly connected sub system monitors, monitoring units and power supply modules through a field bus, through multiple main information interaction and bus information sharing of the field bus, the redundant backup function of the power supply equipment is realized, and the irreversible damage such as power supply module damage and battery charging damage or evacuation caused by no monitoring management of the original integral power supply equipment is avoided.

Description

technical field [0001] The invention relates to a method for improving the reliability of a power supply system by monitoring redundant backup, in particular to a method for improving the reliability of the entire power supply system by establishing redundant backup between system monitoring and monitoring of each subsystem in an integrated power supply system Integrated power system reliability technology. Background technique [0002] The integrated power supply includes one or more combinations of DC power supply, AC power supply, communication power supply, inverter power supply and low-voltage distribution power supply. As the uninterrupted power supply equipment of the substation, the integrated power supply equipment is the most basic requirement for it to have the ability of uninterrupted power supply. Once the power is cut off, it will have a huge impact on the entire substation. Therefore, how to prevent the normal operation of the integrated power supply device f...
