摘　　要：IEC 61850标准将变电站系统划分为变电站层、间隔层、过程层,并规范了过程层与间隔层的通信方式。文章根据IEC 61850标准描述的采样值传输服务模型及IEC60044-7/8标准定义的合并单元模型,设计了遵循IEC61850-9-1通信规约的传统电磁式互感器合并单元,并对其性能进行了测试分析,采样精度和传输延迟指标都达到了电力系统标准对模拟合并单元的要求,对传统变电站改造工程有一定的参考意义。The IEC 61850 standard divided the substation system into the substation level, the bay level, the process level, and standardized process level and gap level communication standards. This paper describes the sampling value transmission service model according to the IEC61850 and the merging unit model defined by IEC60044-8. We designed the merging unit which could gather sampling value of analog signals from the traditional transformers that followed the IEC61850-9-1, and verified its function. The sampling accuracy and transmission delay met standards of power system to analog merging unit. It is significant to reconstruction proiect of the traditional substation
