智能电子设备面向对象的软件设计方法

Object Oriented Software Design Method of Intelligent Electronic Device

为解决数据映射带来的智能电子设备软件复杂、低效和无法利用SCL文件对功能进行灵活组态的问题,基于IEC61850标准的面向对象思想,在信息源头采用面向对象设计;根据IED能力描述文件,构建智能电子设备对象;使用IED组态工具,导入IED实例配置文件,灵活配置IED运行需要的对象;当IED运行时,通过多个对象交互完成装置功能,进一步讨论了该方法在不同硬件平台上的适用性。最后,将该方法应用于间隔层保护测控IED的软件设计,达到IED功能软件与IEC61850面向对象信息模型无缝融合和可灵活组态的效果。

Data mapping method brings about the complexity and low efficiency of intelligent electronic device（IED）software,and can not utilize SCL files to flexibly configure IED functions. In order to resolve this problem,the object oriented design based on the object orientation of IEC61850 is adopted at the information source. According to IED capability description（ICD）file,IED objects are constructed;through importing configured IED description（CID）file,an IED configuration tool is used to flexibly configure the objects required for the IED running;when IED runs,multiple IED objects interact to implement the device functions. And then,the applicability of this method under different kinds of hardware platforms is discussed. Finally,this method is applied to the software design of bay protection and control IED,and the purposes of merging seamlessly the functional software of IED and the object oriented information model of IEC61850 and configuring flexible IED functions via SCL files are achieved.
