This paper expounds the receiving and dispatching scheme of SV using a point-to-point direct sampling and the GOOSE transmission mechanism, analyzes the communication model and the packet structure of SV and GOOSE. Based on this, a method of sharing the same port by SV direct sampling and GOOSE transmission is put forward. The equipment in the process level uses the time division multiplexing for the transmission channel, and sending the GOOSE message at the idle time of SV message transmission. The equipment in the bay level uses the receiving mechanism of Ethernet controller and adopts FPGA to control directly, and solves the problem that the general Ethernet controller cannot distinguish the SV from GOOSE message, which causes chaotic time scale in resampling. The theoretical analysis and practical application show that the scheme has practical significance for popularization, because it does not involve hardware changes, the software process is simple, it has a high reliability, and it is easy to implement.
