摘　　要：合并单元是电子式电流/电压互感器与变电站间隔层设备接口的重要组成部分。在研究了IEC61850信息模型内涵的基础上,从分析合并单元的功能入手,构建了合并单元的信息模型。信息模型采用结构化的描述方法将服务器分为逻辑设备、逻辑节点、数据、数据属性4个层次。研究了基于发布/订户传输机制的采样值传输模型的实现方法,提出发布/订户通信机制是一个或多个数据源向多个接收者(订户)发送数据的最佳选择。分析了为互操作提供基础性支持的目录和数据定义服务。Merging unit is an important component of the interface between ECT/EVT and the baylayer device of substation. Based on the study of IEC61850 information model and the analysis of merging unit functions,an information model of merging unit is developed. The structural description method is adopted and the server is divided into d layers in the model：logical device, logical node,data,and data attribute. The implementation method of SV（Sampled Value） transfer model is investigated and it is presented that the publisher/subscriber communication architecture is the best way to send data to several receivers（subscribers） by one or several data sources. Directory and data definition services,which offer fundamental supports to interoperability,are also analyzed.
