摘要
提出一种基于IEC 61850标准的保护设备重构方案。借鉴IEC 61131-3标准,对IEC 61850标准中保护逻辑节点(LN)进行组件化封装。将传统的保护逻辑模块设计为LN内部的功能块,为LN组件定义多种信号接口,对保护LN组件内部的保护逻辑、各LN之间的配合、分布式功能下各设备之间的虚拟交互关系加以刻画,增加了各设备之间的虚连接,构造了保护设备的虚拟输入/输出信息。采用可扩展置标语言(XML)表达保护设备重构后的配置与虚拟交互信息,并给出实例说明其可行性。该方案可促进保护设备的开发与管理,并且是对系统配置的有益补充。
A reconfiguration scheme of protection logic and virtual interaction among protection equipments based on IEC 61850 is proposed.The protection logic nodes（LNs）in IEC 61850have been encapsulated into the components by reference to IEC 61131-3.The traditional protection logic modules are designed as LN internal function blocks,and the signal interfaces are defined with the LN data of IEC 61850.The internal protection logics of protection LN components,the coordination among LNs as well as the virtual interaction relationships among devices with distributed function are described.The virtual connections among devices are added and the virtual input/output information of protections is constructed.Using the XML language,the configuration and interaction information for reconstructed protection devices are described.The design examples given show it is feasible.The new scheme can promote development and management of protection device;as well,it also gives some valuable supplements for the system configuration.
