摘要

The time synchronization data of intelligent terminal can be used to collect the state change and the change time information of the intelligent substation switch equipment. According to the theory of digital signal processing, combined with GOOSE time scale data, the real time re⁃sponse mechanism of the port signal of intelligent terminal is analyzed in this paper. Considering the hardware structure and IEEE802.3, the physical layer signal of GOOSE information is dis⁃cussed. Through the SOE signal simulation, GOOSE signal response and GOOSE information descrip⁃tion, the feasibility of the intelligent terminal detection method based on physical layer digital sig⁃nal is verified.%智能终端时间同步的时标数据，可用于采集智能变电站开关设备的状态变位与变位时间信息。本文根据数字信号处理理论，结合GOOSE时标数据，分析了智能终端的端口信号实时响应机理；综合考虑硬件结构与IEEE802.3，讨论了GOOSE信息的物理层信号。通过SOE信号仿真、GOOSE信号响应和GOOSE信息描述，验证了基于物理层数字信号的智能终端检测方法的可行性。
