A network risk monitoring system for substations

Abstract

The present invention provides a network risk monitoring system for a substation, the system includes: a collection and monitoring module for real-time collection of monitoring data, a safety analysis and perception module for performing substation network security risk perception, and comprehensively analyzing the collected monitoring data, and then Evaluate the threat level of different network security events faced by the substation network; the defense alarm module is used to realize the hierarchical early warning and active defense of different network security events based on the evaluation results of the security analysis and perception module. The system of the present invention is used for real-time monitoring of the substation network, quickly analyzes the threat degree of different network security events to the substation network, and responds quickly, realizes hierarchical early warning and active defense of different network security events in the substation network, and timely eliminates security risks. hidden dangers and ensure a safe and clean network environment for the substation.

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 Background technique [0002] In substations, especially smart substations, traditional cables have been replaced by networks.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 any local area networ...

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.
