摘　　要：随着计算机技术和通信技术的发展,继电保护在线监测相关研究已经取得进展,可避免当前人工定期检验所带来的过剩维修的问题。提出了智能变电站继电保护及相关设备的在线监测系统级解决方案,定义了保护设备状态监测信息和传输方式,设计了智能变电站继电保护二次回路的物理链路和逻辑链路的在线监测方案。该方案在投运的新一代智能变电站进行了继电保护在线监测系统的工程化应用,实现了智能变电站继电保护装置以及二次回路在线监测,提高了智能变电站继电保护的运维水平。With the development of computer and communication technology, investigation of on-line monitoring for relay protection system has made important progress, and could solve the over-maintenance problem caused by the traditional time-based maintenance approach. The paper promotes system-level solutions for on-line monitoring of relay protection system and related device in the intelligent substation, defines state-detecting information of protecting device and corresponding transmission mode, and designs on-line monitoring scheme for physical link and logic link of secondary circuit in relay protection system. Finally, engineering application of on-line monitoring for relay protection system in the intelligent substation shows that the solution can accomplish on-line monitoring on relay protection device and secondary circuit, which effectively increases the reliability of relay protection system.
