Intelligent substation process layer virtual connection fault positioning system

Abstract

The invention discloses an intelligent substation process layer virtual connection fault positioning system, which comprises a virtual connection fault positioning system, a network monitoring management data cloud, a process layer switch and intelligent electronic equipment; the virtual connection fault positioning system is used for calculating and generating a virtual connection actual communication link, comparing the virtual connection logic loop with the actual communication link, indicating that the virtual connection of the process layer network is abnormal if the virtual connection logic loop and the actual communication link are inconsistent, and transmitting the fault positioning information to a network monitoring management data cloud; the network monitoring management data cloud is used for storing network operation data and virtual connection fault positioning data to form a fault analysis report. The mapping relation of the process layer network communication virtual connection is vividly displayed in a graphic mode, and the preset process layer network communication virtual connection is compared with the actual process layer network communication virtual connection, so that the real-time monitoring of the process layer network and the fault positioning are realized.

Description

technical field [0001] The invention relates to the field of intelligent substation network monitoring, in particular to a virtual connection fault location system for the process layer of an intelligent substation. 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. Due to the particularity of the structure and function of the smart substation automation system ...

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 IED virtual connections
