Embodiment 1

[0020] Such as figure 1 Shown is a flowchart of a method for suppressing a network storm in a smart substation provided by an embodiment of the present invention, and the method includes the following steps:

[0021] In step S101, the message is matched according to the transmission characteristic of the message, and the transmission characteristic includes: transmission path, packet flow and sending path.

[0022] In the embodiment of the present invention, the messages used to send messages in the smart substation include: Goose (Generic Object Oriented Substation Event for short: Generic Object Oriented Substation Event) message, SV (Sample Value for short: sampling value) message, MMS ( Manufacturing Message Specification for short: manufacturing message specification) message, and timing message. So in this step can be divided into:

[0023] 1. Match the Goose message according to the transmission characteristics of the Goose message, the transmission characteristics in...

Embodiment 2

[0052] Such as figure 2 Shown is the structural diagram of the smart substation network storm suppression device provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0053] The matching unit 201 is configured to match the message according to the transmission characteristic of the message, and the transmission characteristic includes: a transmission path, a packet flow, and a sending path.

[0054]In the embodiment of the present invention, the messages used to send messages in the smart substation include: Goose (Generic Object Oriented Substation Event for short: Generic Object Oriented Substation Event) message, SV (Sample Value for short: sampling value) message, MMS ( Manufacturing Message Specification for short: manufacturing message specification) message, and timing message. The matching unit 201 includes:

[0055] Goose message matching sub...

Abstract

The present invention is applicable to the field of data processing, and provides a method and device for suppressing network storms in intelligent substations. The method includes: matching messages according to the transmission characteristics of the messages, and the transmission characteristics include: transmission path, message flow and A sending path; comparing the message with a preset change threshold; when the message exceeds the change threshold, suppressing the flow of the message. In the embodiment of the present invention, various messages in the intelligent network substation are matched, and the matched message is compared with a preset change threshold according to the type of the message. When a network storm occurs, the message exceeds the change threshold When the flow of the message is suppressed, different processing of different messages is realized, and the harm of the network storm to the intelligent network substation is effectively suppressed.

Description

technical field [0001] The invention belongs to the field of data processing, in particular to a method and device for suppressing network storms in intelligent substations. Background technique [0002] At present, because the general-purpose switches of smart substations cannot accurately identify all types of business flow packets, when suppressing network storms, they still treat Goose and SV packets in the same way as other types of packets, and cannot treat important Goose packets. Messages are distinguished from SV messages and processed specially. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method and device for suppressing a network storm in a smart substation, so as to solve the problem that different messages in the smart substation cannot be differentiated and processed in the prior art. [0004] The embodiment of the present invention is achieved in this way, a method for suppressing a network sto...
