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。在电力系统通信中,需要从各种设备采集数据。文章从数据采集角度,简要介绍了103通信规约,并在此基础上提出了无差别通信流程这一个概念,解决了103通信过程中,规约相同但通信流程却不相同的问题,也为电力系统软件开发采用统一标准提出了一个可行的方案参考。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 protecting is based. But the detailed communication processes are quite distinct.In the power system communication,data need to be collected from different installations.In this aspect,the article gives a brief introduction of the 103 transmission protocol and bring forward the nondisparate communication procedure.It can solve the problem that the protocol is the same but the communication procedure is different during the 103 communication process.And it also provides a feasible reference for the unitary criterion of the power system software development.
