Network risk monitoring system of transformer substation

Abstract

The invention provides a network risk monitoring system of a transformer substation. The system comprises a collection monitoring module used for collecting monitoring data in real time, a security analysis perception module used for performing transformer substation network security risk perception and comprehensive analysis on the collected monitoring data and further evaluating threat degrees of different network security events which the transformer substation network is faced with, a defending and alarming module used for realizing graded early warning and active defense for different network security risks based on the evaluation result of the security analysis perception module. The network risk monitoring system of the transformer substation is used for monitoring the transformer substation network in real time, analyzing threat degrees of different network security events to the transformer substation network rapidly and making out a response rapidly, realizes graded early warning and active defense for different network security events in the transformer substation network, removes security hazards in time and guarantees that the transformer substation has a secure and clean network environment.

Description

technical field [0001] The invention relates to the field of substation management and control, in particular to a network risk monitoring system of a substation. Background technique [0002] In substations, especially smart substations, traditional cables have been replaced by networks. Whether it is a fiber optic network or an electrical Ethernet network, it builds a bridge for communication between all equipment in the substation and shoulders the mission of safe and stable operation of the substation. While the Internet is changing with each passing day, network security is getting more and more attention. In order to ensure the network security of the power system, various firewalls and encryption devices have been widely used, which mainly solve the network security problem of accessing the dispatching data network outside the substation to the substation, and achieve the isolation of the network inside and outside the substation. However, once there is a problem th...

AI Technical Summary

Problems solved by technology

However, once the local area network in the substation has a problem that seriously affects the stability of the network security, such as a network storm, it will affect the security and stability of the substation.
