摘要
在变电站新型通信网络和系统协议IEC61850的基础上,研究智能电子设备IED(Intelligent E lectron icDevice)的模型,以变压器差动保护为例,分析了IED在IEC61850中的体系结构、逻辑模型、信息流,设计了该IED的数据对象模型,阐述了采样测量数据基于发布/订阅方式的传输原理,给出了仿真试验说明该IED设计的先进性和可行性。
The model design of novel lED （Intelligent Electronic Device） based on the new substation communication network and standard IEC61850 is presented. The system architecture of IEC61850 is analyzed firstly. And logical model, information flow, data object model of IED are given in the following, with the design of transformer differential protection as a sample. The transmitting prirrciple of sample values from ECT to IED based on publish/subscribe is expatiated. The test simulation indicates the advantages of the novel IED.
