Transformer substation communication network state online monitoring system and method

Abstract

The invention provides a transformer substation communication network state online monitoring system and method. The monitoring system comprises a state managing area, a state monitoring area and a state judging area. A communication network flow failure action threshold value is set and calculated through the state managing area; exchange messages at all ports of all exchangers are mirrored to the monitoring system in real time through the state monitoring area, the messages, devices and network performance are monitored in real time, the network measured flow is inputted to the state judging area, and meanwhile the message analysis content is conveyed to the state judging area; initial failure judgment is conducted through the state judging area according to the monitoring message time sequence and the message coding reasonability, the network measured flow and the network flow failure action threshold value are compared, and network failures are positioned, controlled and recovered. The transformer substation communication network state online monitoring system and method have the advantages that the online monitoring capacity and the real-time protection capacity are achieved, and the requirement of an intelligent transformer substation for the reliability of a communication network can be met.

Description

technical field [0001] The invention relates to the field of network monitoring, in particular to an on-line monitoring system and method for substation communication network status. Background technique [0002] Networked substation data transmission and information sharing are the most important features that distinguish smart substations from traditional substations. The communication network is the main channel for data transmission and information sharing in smart substations, and it is also the basis for the realization of functions such as normal operation and dispatch control of smart substations. important meaning. In order to improve the reliability of the substation communication network and improve the operator's ability to control the communication network, it is necessary to establish a complete substation communication network status monitoring system and a matching monitoring content setting method. [0003] At present, the smart substation communication ne...

AI Technical Summary

Problems solved by technology

[0004] The communication network monitoring method that combines smart substation communication records and offline analysis requires large-capacity and high-reliability storage devices to record network information, which increases the investment in substation construction; The invoked analysis record messages only account for 0.1% of all record messages, resulting in a large waste of record messages

More importantly, the communication network monitoring method of network communication records and offline analysis is a solution for post-event analysis, that is, after an accident, it is necessary to call stored messages and professional message analysts to find and solve network faults. This communication network protection control method does not have the ability of online monitoring and real-time protection, and it is difficult to meet the reliability requirements of smart substations for communication networks.
