Abstract

The invention provides a message filtering method and an applicable FPGA and an intelligent substation. The method comprises the following steps: filtering messages directly obtained from an Ethernet physical layer standard interface according to a preset message transmission manner in the intelligent substation by the FPGA; temporarily storing the filtered messages in a classified manner according to the types of the messages transmitted by the intelligent substation; and matching a change rule of feature information in preset fields of the messages within each preset number of each type and/or a preset duration of each type with the change rule of preset feature information in a corresponding message type, and filtering the messages according to the filtering result. The message filtering method provided by the invention is used for effectively improving the message filtering speed of the intelligent substation.

Description

technical field [0001] The invention relates to the field of intelligent substation networking, in particular to a message filtering method and applicable FPGA and intelligent substation. Background technique [0002] At present, most process layer networks of smart substations use Ethernet for data exchange of SV and GOOSE messages. The Ethernet network storm caused by various reasons will inevitably have unpredictable impact on the transmission of valid packets. [0003] The characteristic of an Ethernet network storm is that a large number of repeated packets appear on the network. These repeated messages will not only occupy the effective network bandwidth, but also increase the load on the processor of the receiving device, and seriously cause the device to fail to work normally. However, due to the particularity of the smart substation network in its field, the equipment needs to be able to quickly process SV and GOOSE messages that are not affected by the network st...
