基于源端数据维护机制的保护智能运维技术探讨

摘要

随着变电站无人值守模式的推进,远程准确判断变电站运行状况成为智能运维技术的关键.智能变电站基于IEC61850标准,IED装置输出的信息量相比于常规综自站具有大幅度提升.提出了一种基于源端数据维护机制的保护智能运维方案,分析了不同数据传输机制的特点,通过工程试点实施验证了技术方案的可行性,为智能变电站保护系统远程运维提供可借鉴的技术路径.%With the development of unattended substation mode,remote and accurate judgment of substation operation status has become the key question of smart operation and maintenance technology.The smart substation is based on IEC61850 and the output information of its IED device is substantially improved compared with the conventional substation automation system.In this paper a scheme of intelligent maintenance operation based on source data maintenance is proposed,and the characteristics of different data transmission mechanisms are analyzed.The feasibility of the proposed technical scheme is verified by an actual project.Therefore the paper provides a technical path for remote operation and maintenance of the protection system of the smart substation.
