阐述了SV采用点对点直采方式的收发处理方案和GOOSE的传输机制，分析了SV和GOOSE的通信模型和报文结构。在此基础上，提出一种SV直采和GOOSE共口传输的方法，过程层设备对传输通道进行时分复用，在SV报文传输的空闲时间完成GOOSE报文的发送；间隔层设备利用以太网控制器的接收机制并采用FPGA对其直接控制，解决了通用型以太网控制器无法区分SV和GOOSE报文导致的重采样时标混乱的问题。从理论分析和实际应用可知，该方案不涉及硬件改动、软件处理简单、可靠性高、易于实现，有着广泛推广的现实意义。

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.
