继电保护的现状与思考

The status quo and thinking of relay protection

在研究IEC 61850标准的基础上,通过对标准中有关数字化变电站描述的相关特点的分析,结合目前微机继电保护的发展现状,对数字化变电站中的间隔层设备的未来发展从研发及应用的角度进行探讨,分别从间隔层设备的硬件、软件、网络及应用方面进行分析,提出保护装置的设计思路:硬件模块化,软件元件化,保护功能网络化,装置功能集成化,并分别对相关方面的观点进行了阐述。

Based on researching IEC61850,analysis of the feature for description of digital substation,and linking the development situation of relaying,this paper discusses the future development of the bay level equipment in digital substation and analyzes the hardware,software,net and application belong to the bay level.It proposes design thoughts of relay protection：modularization of hardware,componentization of software,networking of relay function,integrating of equipment function,and expounds the relevant aspects.
