A Substation Network Monitoring and Early Warning System for Efficient Identification of Network Attacks

Abstract

The invention discloses a substation network monitoring and early warning system for efficiently identifying network attacks, belonging to the field of substation network monitoring, and a substation network monitoring and early warning system for efficiently identifying network attacks. When network traffic is abnormal, a monitoring and early warning module feeds the information back to The centralized control station, the centralized control station controls the power failure of the electromagnet, and the intelligent inflatable device inflates the self-disconnecting collar, so that the plugged network cable is disconnected, thereby realizing the signal transmission channel between the substation end and the centralized control station, and thus significantly Effectively reduce the impact range of network attacks and effectively reduce losses. When the network traffic returns to normal, control the electromagnet to energize, and control the intelligent inflatable device to deflate at the same time. At this time, the two electromagnets are attracted to each other, which in turn drives the automatic plugging of the plugged network cable. It is closed to restore the signal connection between the substation and the centralized control station without manual operation, which significantly improves the speed of restoration of the connection between the two, and facilitates the centralized control station to grasp the information of each substation station in time.

Description

technical field [0001] The invention relates to the field of substation network monitoring, and more particularly, to a substation network monitoring and early warning system for efficiently identifying network attacks. Background technique [0002] As the power dispatching automation system and the substation monitoring system are basically networked, the network security problems of the power dispatching system and the substation monitoring system are becoming increasingly prominent. Along with the sixteen characters of "safety partition, dedicated network, horizontal isolation, and vertical encryption", the power system has successively deployed vertical encryption authentication devices and horizontal isolation devices on the power dispatching data network, strengthening the network boundary between the substation and the dispatching data network. The traditional thinking believes that the substation monitoring system network is physically isolated from the public networ...

Problems solved by technology

However, the network security protection of the substation is relatively weak. Once it is attacked by the network, it is easily affected, and there is a hidden danger of information leakage in the substation, which is easy to cause large losses.
