基于过程总线的继电保护实验平台开发

摘要

为了研究继电保护技术在智能变电站的应用,参考标准IEC 61850重新构建微机继电保护装置功能,并引入过程总线技术升级传统电保护实验平台,设计了PC控制的过程总线适配器,解决异构通信端口的设备之间的通信难题;以GOOSE和SMV报文传输继电保护指令为例,介绍了IEC 61850在该实验平台上的应用.借助该实验平台,学生可便利地实施智能变电站的继电保护实验,学习IEC 61850标准.%In order to research the application of relay protection technology in smart substation,and according to the standard IEC 61850,the function of microcomputer protection device is reconstructed,and the process bus technology is introduced to upgrade the traditional electrical protection experimental platform.The process bus adapter by PC control is designed,and the communication problems between the devices of heterogeneous communication ports are solved.Taking GOOSE and SMV message transmission relay as an example,the application of IEC 61850 on this experimental platform is introduced,and with the aid of this experimental platform,the students can conveniently implement the experiment on the relay protection of smart substation and study the IEC61850 standards.
