摘　　要：从变电站的现场实际情况出发,结合目前电子器件及微处理器方面的最新技术,提出一种基于DSP的新型变电站自动化系统,介绍了以TMS320F2407DSP芯片为核心的智能化断路器的特征及功能,以此为基础,构成了一体化的变电站自动化系统。阐述了从单个节点到多个节点的设计原理及实现,在此基础上分析了网络的七层协议,定义了一套应用于现场的通信规约,详细说明了此规约的通信原理及实际使用情况。According to the real conditions of substations, a substation automation system equipped with DSP-based intelligent devices is brought forward,which combines with the new technologies in electronic equipment and microprocessor. The features and functions of an intelligent circuit breaker,with TMS320F2407 DSP as its core,are described,based on which an integrated substation automation system is constructed. The principle and realization of mono - and multi-node design are indicated and the seven - layer network protocol is analysed. A set of communication protocol fit for field operation is presented,and its principle and application are detailed.
