摘　　要：从与我国现有变电站自动化系统间隔层设备比较的角度出发,研究了变电站新型通信网络和系统协议IEC61850中的智能电子设备IED的模型,分析了IED在IEC61850体系结构中的作用与逻辑模型、数据对象模型、通信网络的性能和通信模式等工作机制,围绕变压器差动保护IED进行了功能模型、信息流、类等方面的设计,说明了新型IED的先进性和可行性。The model study of novel lED based on new substation communication network and standard IEC61850 is presented, compared with existing device of traditional substation automation system. The working mechanisms of IED are analyzed on the architecture of IEC61850, logical model, data object model, and the performance and mode of communication network. The designs of function model. information flows and classes of IED of transformer differential protection are given, the testing simulation indicates the advantages of the IED design.
