Intelligent substation process level network monitoring management system

Abstract

The invention discloses an intelligent substation process level network monitoring management system. The system comprises a monitoring host, wherein the monitoring host generates preset process levelnetwork communication state information through SCD configuration of an intelligent substation; and the monitoring host acquires the operation state information of the process layer switch in real time, analyzes and processes the operation state information acquired in real time to obtain actual process layer network communication state information, and compares the actual process layer network communication state information with preset process layer network communication state information to realize operation state monitoring of the process layer switch. The intelligent substation process level network monitoring management can be rapidly and reliably completed in real time, monitoring data are complete and reliable, the alarm response speed is high, and the network security of the intelligent substation is ensured; and moreover, the mapping relation between the process layer network communication physical link and the virtual connection is graphically displayed, and the fault visual positioning of the process layer network physical link/virtual connection is realized.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to an intelligent substation process layer network monitoring and management system. Background technique [0002] The intelligent substation automation system based on Ethernet communication technology realizes the communication and sharing of information between primary and secondary equipment. At the same time, the various functions of the intelligent substation automation system in turn put forward higher requirements for the real-time performance of Ethernet communication technology. . Compared with traditional substations, optical fiber networks are used in smart substations to transmit information, making industrial Ethernet switches gradually replace traditional cables and become key equipment for communication networks in smart substations. The particularity of the structure and function of the intelligent substation automation system has high requirements ...

AI Technical Summary

Problems solved by technology

When a certain device is abnormal, it may cause multiple connected devices to send link abnormal signals. After seeing a large number of link error messages, operators may be at a loss and cannot quickly and accurately locate faults and abnormalities.

At the same time, most of the existing network monitoring systems cannot support the graphic display of virtual links and physical links in process-level network communication
