Embodiment 1

[0042] Such as figure 1 As shown, it is a schematic diagram of the framework of the IEC61850 chip network controller provided by the present invention. The present invention provides a network storm suppression device based on the IEC61850 chip. The suppression device is implemented by the IEC61850 chip, and the IEC61850 chip is used for programmable network storm detection and Network storm suppression. The IEC61850 chip includes a control module, a DPRAM and an IEC61850 conversion module connected in sequence; the control module includes an input and output module, a main control module and an HML processor, and a network controller is embedded in the IEC61850 chip, and the network controller and the The input and output modules are connected; the network controller is used to control the working mode of the network card according to the requirements.

[0043] Further, the IEC61850 chip also includes a communication module 101, a storm criterion module 102, a discrimination...

Embodiment 2

[0059] The present invention also provides a suppression method of a network storm suppression device based on the IEC61850 chip, such as figure 2 As shown, the network storm is judged according to the network storm rule. After the network card performs hardware filtering on the message, the network card module in the chip first judges according to the destination MAC address of the message, classifies the message type, and classifies the multicast, The broadcast message is judged. If it is a broadcast message, then whether there is a network storm. If there is a storm in a certain destination MAC message, the message can be discarded directly to avoid the impact of the storm message on the IEC61850 protocol communication of the chip; Send business applications. If it is a multicast message, determine whether it is an SV message or a GOOSE message. If it is an SV message, repeat the suppression process similar to broadcast messages. If it is a GOOSE message, when it is judge...

Description

technical field [0001] The invention belongs to the field of power system automation, and in particular relates to a network storm suppression device and method based on an IEC61850 chip. Background technique [0002] In smart substations, the IEC61850 standard has been widely used. The network communication based on the station control layer and the process layer has laid a solid foundation for the realization of substation information sharing. However, network-based information transmission brings network security problems to a certain extent. For example, accidents caused by network storm hazards have become an important topic in the research of smart substations. Under the impact of extreme network operating conditions and traffic, equipment will run too slowly, restart or crash. Therefore, in the smart substation environment, effective measures should be taken to avoid network storms. [0003] Most of the current network storm suppression measures use some network st...
