采用IEC 61850的变电站间隔层IED软件设计方案

IEC 61850的特点是建立分层的体系结构、统一对象模型和抽象通信服务接口(ACSI)等，实现智能电子设备（IED）之间的互操作性，降低整个系统设计、集成、运行、维护等费用。以研究IEC 61850下间隔层IED的软件设计方案为目标，分析IED的功能模型，设计其软件内部模块的组成，阐述了软件设计所涉及的统一建模语言（UML）设计、可扩展标记语言（XML）、通用的面向对象的变电站事件（GOOSE）、采样值传输（SAV）、通用变电站状态事件（GSSE）等报文的通信模式和多任务运行等关键技术的工作原理及设计方法，为遵循IEC 61850的变电站间隔层IED产品研发提供了一定的借鉴和参考。

IEC 61850 Based Software Design Scheme of Bay Level IED in Substations

IEC 61850 realizes the interoperability among intelligent electronic devices (IEDs) by setting up a layered architecture, a unified object model and an abstract commutation service interface, thus reducing the cost of design, integration, operation and maintenance of the system. The software design scheme of bay level IED based on IEC 61850 is studied, the function model of IED analyzed and the module composition of software designed. The principles and implementing methods of such key technologies as UML design of the object model, XML, communication modes of GOOSE, SAV, GSSE message and multi-task running are studied. Some references are put forward for the product development of the new IEDs obeying IEC 61850.
