摘要
为实现配电自动化系统(DAS)中的信息共享和智能电子设备(IED)之间的互操作性能,在IEC61850标准的基础上,结合嵌入式技术,设计了新型的馈线自动化终端设备模型,并对其在DAS的应用做了一定的探讨。在对该设备各主要模块功能分析的基础上,将各模块功能分解为多个逻辑节点的组合,实现系统的功能建模和系统建模,搭建了IED的"ARM+DSP"双CPU结构硬件平台;在对IEC61850标准的信息分层、面向对象的数据对象统一建模、数据自描述和抽象通信服务接口(ACSI)及特定通信服务映射(SCSM)等概念分析的基础上,提出了基于以太网并符合IEC61850标准的IED通信模型。
To realize information sharing for DAS（ Distribution Automation System） and the interoperability of its IEDs （ Intelligent Electronic Devices） , a new model of FTU （ Feeder Terminal Unit） is designed based on the IEC61850 standard and the embedding technology, with its applications in DAS discussed. Functions of its main modules are analyzed and resolved into multiple logic nodes to realize function modeling and system modeling. A dual-CPU of ARM and DSP is set up. Some concepts are analyzed, such as information delamination of IEC61850 standard, object-oriented and unified modeling, data object self-description, abstract communication service interfaces, special communication system service mapping and so on, on the basis of which an Ethemet-based communication model conforming to IEC61850 standard is proposed.
