摘　　要：针对当前变电站继电器人工定期检测存在效率过低、检测不到位、工人劳动强度大以及无法实现可视化等问题,本文提出了变电站智能继电保护及相关设备的在线监测系统方案,研究了变电站智能继电保护在线监测系统的组成,介绍了保护设备状态监测信息的传输方式。经现场应用表明,本次提出的在线监测系统方案实现了变电站的智能继电保护装置的在线监测,同时对二次回路进行了远程在线监测,根据差动曲线的变化趋势可准确判断继电器的故障,从保护装置显示的COMTRADE格式的波形可得出故障的原因,有效提高了变电站的智能运维水平,降低了运维成本。In view of the problems of manual regular detection of substation relay,such as low efficiency,inadequate detection,high labor intensity of workers and unvisualization,this paper proposes the on-line monitoring system scheme for substation intelligent relay protection and related equipment,study the composition of the online monitoring system of the intelligent relay protection of the substation,introduced the transmission mode of the status monitoring information of the protection equipment.The field application shows that the proposed online monitoring system solution realizes online monitoring of intelligent relay protection devices in substations and remote online monitoring of secondary circuits,and can accurately determine relay faults based on the change trend of differential curves,and can derive the cause of faults from the waveforms in COMTRADE format displayed by the protection devices,effectively improving the intelligent operation and maintenance of substations,reducing operation and maintenance costs.
