摘　　要：C37.94标准由IEEE于2002年制定,该标准规范了远方保护设备和数字复用设备之间的光纤通信接口的帧结构、时钟定时等内容。文章首先描述了继电保护线路纵差保护系统的结构,分析了光纤保护的应用现状及其局限性,介绍了IEEE C37.94标准的主要内容和意义,最后以一个典型案例说明了该标准的实际应用。The C37.94 standard has been issued by IEEE in 2002 which defines the frame structure and clock timing of optical fiber communication interface between equipment of tele-protection and multiplexer. This paper first describes the structure of line longitudinal differential protection system, and then analyzes the actuality of optical fiber relay protection and its limitations. It introduces the main contents and meaning of IEEE C37.94 standard. The practical application of this standard is also explained through a case in the paper.
