摘　　要：设计了一种基于背板总线的继电保护装置平台架构。该方案优化装置内部数据流和配置流程,提升装置面向过程总线的通信及数据处理能力。在分析继电保护装置的功能及性能要求的基础上,提出过程总线功能设计总体架构;根据应用数据类型设计背板总线数据流和配置流程,分析以太网扩展、采样值接收与同步、报文透明传输等问题;基于IEC61850模型导出背板总线配置信息并设计下载流程。该设计方案在110 kV智能变电站主变保护测控一体化装置中得到应用,满足装置面向过程总线的功能及性能要求,现场运行结果表明该设计方案的有效性和实用性。A kind of relay protection platiorm based on backboard bus is deslgne（1,wlalcn,wltn me optimized internal data flow and configuration process,enhances the process-bus-oriented communication and the data processing ability. The requirements of relay protection in functions and performances are analyzed,and a general framework of process bus function design is put forward. The data flow and configuration process are designed according to the types of application data and several topics are discussed ,such as Ethernet extension,sample receiving and synchronization,transparent message transmission, etc. The configuration information of backboard bus is deduced based on IEC61850 model and its download process is designed. The proposed design scheme is applied in the integrated measuring and control device of primary transformer protection for 110 kV smart substation and the requirements for process-bus-oriented functions and performances are satisfied. Site operation proves its effectiveness and practicability.
