摘　　要：IEC60870-5-103通信规约是电力系统通信常用的通信规约,许多继电保护设备的通信模块都是基于这个规约设计制造的,但详细的通信流程却大不相同。首先在分析研究了微机馈线保护装置硬件结构的基础上,重点论述了基于以太网的103规约的实现方案,然后提出了一种有限状态机的软件设计方法,并利用Linux环境下的Socket编程,实现了基于以太网的103通信规约的软件编程。IEC 60870-5-103 transmission protocol is the most popular protocol used in power system communication, on which the design of many communication modules of relay protection is based, but the detailed communication processes are quite distinct. This paper briefly analyses the hardware devices of microprocessor-based feeder line protection equipment. On the basis of which, implementation of Ethernet-based 103 protocol is focused and then the software design method of finite state machine is proposed. The Socket Programming in Linux environment is employed to achieve the software programme of Ethernet-based 103 transmission protocol.
