基于IEC 61850MMS的继电保护故障信息系统通信机的实现

最新正式颁布的IEC 61850规约势必在不久的将来成为电力系统中从变电站到调度中心之间主流的通信规约。文中研制的电网继电保护故障信息系统是国内第一次实现了以IEC 61850MMS作为主站与子站通信协议的电力自动化系统,并且已经在浙江省电力公司试运行。作为枢纽的协议通信机是该继电保护故障信息系统的关键部分。围绕协议通信机的实现论述了有关IEC 61850和MMS的概要知识以及两者对象之间的相互映射关系,介绍了协议通信机的整体框架,详细讨论了协议通讯机IEC 61850MMS编/解码模块以及多线程通讯模块的设计和实现。

Communication machine implementation of relay protection and fault information system based on IEC 61850 MMS

As the international standard for substation automation network communication,IEC 61850 will gradually be used from substation to control center as a primary standard.Power relay protection and fault information system,this paper developed,is the first implementation to use IEC 61850MMS as the communication protocol between master station and substation in domestic domain.This system has been test run in Zhejiang Electric Power Co.As the key role,communications machine implements a connecting link between the preceding and the following function.This paper studies the basic knowledge of IEC 61850 and MMS.And the concrete realization of the IEC 61850MMS communications machine is discussed as well.
