摘　　要：近年来,对智能变电站深入研究、推广应用促进了国内外各项技术的标准化进程。基于泛在电力物联网标准体系的研究背景,首先综述了智能变电站自动化与保护技术国内外标准化工作现状;其次阐述了IEC框架下变电站自动化与保护技术的标准构成,详述并分析了其3个核心标准的体系架构及关键技术的进展,其中,IEC 61850包括配置语言、信息模型、服务映射、网络通信,IEC 60255包括保护开入/开出数字化、传输时延、同步相量测量,IEC 61869包括总体技术要求、中压低功率互感器、数字接口与合并单元。最后从体系架构、信息模型继承、功能标准制定、全维度信息安全、国内外标准一体化研制等5个方面提出了相关建议。In recent years, the in-depth research, promotion and application of smart substation have accelerated the standardization process of various technologies in China and abroad. Firstly, based on the research background of ubiquitous electric power internet of things(IoT) standard architecture, this paper summarizes the present standardization situation of the smart substation automation and relay protection technologies in China and abroad. Secondly, it elaborates the standards constitution of substation automation and relay protection technology in IEC framework, and analyzes the system architecture and key technical progress of the three core standards. IEC 61850 includes configuration language, information model, service mapping and network communication. IEC 60255 includes relay protection switch input/output digitization, data transmission delay, and synchrophasor measurement. IEC 61869 includes general technical requirements, medium-voltage low-power transformers, digital interfaces and merging unit(MU). Finally, the paper presents related suggestions on five aspects, including system architecture, information model inheritance, functional standard formulation, full-dimension information security, and integration research of domestic and international standards.
