摘　　要：光纤纵差保护对线路提供了安全可靠的保护,其关键在于解决通信问题。文中在阐述了同步原理和抗干扰编码机制的基础上,提出了一种可靠、实用的通信方式及其使用的报文帧格式。实践表明这种通信方式能够获得较好的同步采样效果和稳健的数据交换功能。Fiber differential protection provides a reliable way to protect electric power line. Its key technique is to solve the transmission of relay protection signal. Based on the theory of synchronization principle and anti-interference encoding mechanism,the paper puts forward a reliable and practical communication method and introduces its message format. It is proved to be a good way to attain synchronized sampling and realize the function of data exchanging.

关 键 词：光纤差动 抗干扰 同步采样 CRC
