Abstract

The invention relates to a common-port transmission method for SV direct mining and GOOSE messages, and belongs to the technical field of relay protection for intelligent substations in electric power systems. According to the transmission characteristics of SV direct sampling and GOOSE messages, the present invention, on the basis of ensuring the accuracy of SV sending time, time-division multiplexes the transmission channel, and transmits and receives GOOSE messages between two frames of SV messages, and according to The specific project configuration file dynamically calculates the number of GOOSE frames inserted between two frames of SV messages, maximizes the use of the transmission bandwidth of the channel, shortens the transmission delay of GOOSE signals, and utilizes the message receiving mechanism of the Ethernet controller to communicate with the FPGA through the FPGA. The resampling time stamp confusion problem caused by the SV and GOOSE packets that the Ethernet controller cannot recognize. Moreover, the GOOSE transmission delay of the present invention is small, does not involve hardware modification, simple software processing, high reliability, easy implementation, and can be widely popularized.
