摘　　要：目前,变电站自动化设备的运维工作主要依赖运维人员的现场操作,增加了运维人员往返变电站现场路程的时间成本,也降低了运维工作效率。为提高工作效率和降低成本,文章提出基于远程运维关键技术的变电站自动化设备远程运维模式,实现对自动化设备远程、安全、高效便携的运维作业。重点论述自动化设备远程运维模式下的关键技术,包括通道管控技术,即管理通道与运维通道,管理通道接收管理类报文管控运维通道的开启与关闭;远程通信安全技术,管理通道与运维通道基于传输层密码协议(transport layer cryptography protocol,TLCP)隧道的安全通信技术;远程安全运维审计技术,运维主站对变电站自动化设备进行安全运维审计技术,具体包括基于安全外壳协议(secureshell,SSH)、安全文件传输协议(securefiletransferprotocol,SFTP)与虚拟网络控制台(virtual network console,VNC)协议的审计、录屏、高危指令拦截、运维过程监控及运维画面阻断,确保运维全过程安全可控;最后,通过对这些关键技术的研究与实现,基本解决变电站自动化设备远程运维安全风险,提高运维工作效率,保证远程运维各环节的安全性与可追溯性。At present,the operation and maintenance of substation automation equipment mainly rely on the on-site operation of operation and maintenance personnel,which increases the time cost for operation and maintenance personnel to travel back and forth to the substation site,and also reduces the efficiency of operation and maintenance work.To improve work efficiency and reduce costs,the article proposes a remote operation and maintenance mode for substation automation equipment based on key remote operation and maintenance technologies,achieving remote,safe,efficient and portable operation and maintenance of automation equipment.This article focuses on the key technologies in the remote operation and maintenance mode of automation equipment,including channel control technology,namely management channels and operation and maintenance channels,management channels receiving management messages to control the opening and closing of operation and maintenance channels;Remote communication security technology,a secure communication technology based on the transport layer cryptography protocol(TLCP)tunnel for management channels and operation and maintenance channels;Remote security operation and maintenance audit technology,the operation and maintenance master station conducts security operation and maintenance audit technology on substation automation equipment,including auditing,screen recording,high-risk instruction interception,operation and maintenance process monitoring,and operation and maintenance screen blocking based on secure shell protocol(SSH),secure file transfer protocol(SFTP),and virtual network console(VNC)protocols,ensuring the safety and controllability of the entire operation and maintenance process;Finally,through the research and implementation of these key technologies,the safety risks of remote operation and maintenance of substation automation equipment can be basically solved,the efficiency of operation and maintenance work can be improved,and the safety and traceability of each link in remote operat
