摘　　要：保护和控制IED(Intelligent Electronic Device)是变电站自动化系统中重要的智能电子设备。IED面向对象设计较传统的面向过程设计具有更好的可靠性、可复用性、可维护性和可理解性。本文针对输电线路电流差动保护,提出了面向对象的IED设计,基于统一建模语言UML进行建模,使用RationalRose作为开发工具建立了功能模型、静态模型和动态模型。Protection and control IED intelligent device in the Substation （Intelligent Electronic Device） is an important Automation System. Compared with the conventional process-oriented method, object-oriented method has the characteristics of more reliable, reusable, maintainable and comprehendible. Object-oriented project design applied in power transmission line current differential protection is presented in this paper, which is based on UML （Unified Modeling Language）. The system functional model, static model, active model are established with Rational Rose as development tool.
