摘　　要：随着智能变电站的快速推广,对站内继电保护设备的运维要求越来越高。传统的定期检修的运维模式已经无法满足供电高可靠性的要求,基于在线运维系统实现状态监测与检修是提高运维水平的关键。在此背景下,重点介绍了如何在智能变电站技术条件下构建和实现继电保护在线运维系统,并对与继电保护密切相关的保护设备状态监测、二次回路状态监测、辅助检修操作等关键技术进行了深入的介绍和探讨。工程应用实例结果说明了所提在线运维系统的实现方法是可行的。Along with the rapid development of smart substations,the maintenance requirements of insubstation relay protections become more rigorous,which could not be satisfied by the traditional periodic maintenance. The key to improve the maintenance level is to realize the status monitoring and conditional maintenance by the online maintenance system. The design and implementation of online maintenance system in the technical conditions of smart substation for its relay protections are emphatically introduced and the key technologies are deeply discussed,such as the status monitoring of protection devices and secondary circuits,the operations of auxiliary maintenance,etc.. The results of an engineering application show the feasibility of the introduced implementation of online maintenance system.
