摘　　要：光纤纵差保护对线路提供了安全可靠的保护,其核心技术是解决两端可靠通信问题。在介绍了20532同步通信芯片特征的基础上,提出了一种基于20532的光纤保护通信方案,详细分析了硬件配置和软件流程。实践表明,这种通信方案能够获得较好的同步采样效果和安全的数据交换功能。Fiber differential protection provides reliable protection for power transmission lines. One of the key concerns lies in reliable communication at two ends. This paper introduces a communication scheme based on chip 20532. It discusses the hardware configuration and the software flow chart. The practice shows that a better synchronization sampling and data exchange function can be realized by this scheme.
