Method of scheduling message in intelligent substation and device

The invention can be applied to the field of data processing, and provides a method of scheduling a message in an intelligent substation and a device. The method comprises steps: messages are classified into Goose messages, SV messages, time synchronization messages and IP messages through first matching; the messages after first matching are classified into quick Goose messages, conventional Goose messages, quick SV messages, conventional SV messages and MMS messages through second matching; the messages after matching and classification are added to VOQ; and the messages in the VOQ are scheduled according to DRR scheduling algorithm and WPQ scheduling algorithm. According to the embodiment of the invention, the messages are matched and classified, the messages after classification are added to the VOQ, and the messages in the VOQ are scheduled according to the DRR scheduling algorithm and the WPQ scheduling algorithm, and therefore, effective transmission of the Goose messages and the SV messages can be effectively ensured when messages of large flow appear in the intelligent substation.
