摘　　要：基于IEC 61850-90-1变电站站间通信标准构建广域保护信息模型。采用分布式系统结构,结合广域电流差动保护算法,扩展新的符合IEC61850-90-1规则的广域电流差动保护逻辑节点,采用隧道通信机制建立基于站间通信的广域电流差动保护信息模型,并给出了站间保护IED交互的信息流。A model of wide area current differential protection based on IEC 61850 -90 - 1, using IEC 61850 for com- munication between substations, is given. By using the distributed structure, taking wide area current differential protec- tion algorithm as reference, the new logic node of the protection complied with IEC 61850 -90 -1 is expanded. Finally the modeling of wide area current differential protection based on communication between substations is given and infor- mation between protection IEDs of different substations is described.
