摘要
根据相关国际标准IEC60044-7/8和IEC61850-9,为适应数字化变电站的要求,电子式互感器与二次保护控制设备间采用合并单元实现数字接口。简要介绍了合并单元在相关国际标准IEC60044-7/8、IEC61850-9-1和IEC61850-9-2中的区别,同时对合并单元的主要功能和实现方法进行了研究和比较。
According to intematinal standards of IEC60044-7/8 and IEC61850-9, the merging unit between the electrinic transformer and the protected control device is adopted to achieve digital interfaces in order to suit the requirements of digital substations. The paper presents differences of the merging unit in ternational standards of IEC60044-7/8, IEC61850-9-1 and IEC61850-9-2. Meanwhile,the main function and achieved method for the merging unit are studied and comparied.
