摘　　要：首先对CIGRE SC B5保护和自动化专业委员会的研究领域、代表、工作组活动、年度会议安排等情况进行了介绍。2012年CIGRE巴黎会议B5学术研讨会的主题有2个:未来电网中的元件对保护和自动化系统配合的影响;远程访问在保护和自动化系统中的应用。柔性交直流输电设备的应用、含分布式电源的非放射式(网络化)配电网等要求采用新原理的继电保护技术,复杂电网中的继电保护、自适应继电保护需要能够自动进行校核的工具。应研究下一代智能变电站,以进一步实现数据和信息共享、二次功能的集成以及新型互感器和过程层总线的应用,同时不能牺牲系统的安全性、可靠性。随着电网拓扑结构的变化,传统稳控系统面临改造,基于离线分析的开环紧急控制将逐步发展到基于在线分析的开环紧急控制。为了降低成本、提高整体运行效益,除了数据采集与监控(SCADA)数据之外,'非实时数据'或者说'非运行数据'在厂站与主站端之间的交换将变得越来越重要,包括故障分析、资产管理和运行等方面的应用。在统一的IEC 61850标准下,远程访问的通信通道和通信协议需要统一设计,网络安全问题必须得到解决。The study scope,delegates,working groups and annual meeting arrangement of CIGRE SC B5—protection and automation are treated first.For the CIGRE Session 2012,preferential subjects for the B5session are the impact of future network components of coordination between protection and automation systems;utilization and application of remote access for protection and automation systems.A new protection scheme is required for application of flexible ac/dc transmission equipments,and meshed distribution network with dispersed generation;automatic verification tools are needed for protection in complex grid,and for adaptive relay protection.The next generation of smart substation has to be studied in order to further realize the data and information sharing,protection and automation function integration,utilization of non-conventional instrument transformer and process bus,in the mean time the security and reliability of the system has to be kept at least at the same level.Along with the network topology changes,the traditional stability control system may gradually transfer from offline study based open-loop emergency control to on-line study based open-loop emergency control.In order to reduce life-time cost and improve overall operating efficiency,in addition to SCADA data,exchange of ＂non real-time data＂ or ＂non operation data＂ between substation and control center will become more and more important,including the application in fault analysis,asset management,operation and so on.Based on the universal IEC 61850standard,the communication channel and the communication protocol of remote access should comprehensively be designed,while cyber security issues should be solved.
