摘　　要：针对变电站直流电源系统支路众多,但缺少统一命名规范而产生的一系列问题,设计了一种一体化直流电源馈出支路告警标签化监控装置。采用长短时记忆网络将显示的支路故障名称替换成现场实际支路名称,提高了故障检查的效率;采用XML Schema协议进行规约映射建模,将IEC104规约和Modbus规约转换成IEC61850规约,使得改进后的软件能够在不同的绝缘检测装置中工作。最后通过测试实验和实际的工程应用效果验证了升级后的绝缘检测装置能够有效的确定发生绝缘故障的支路,提升了排查故障的效率,对直流系统提升维护效率提高可靠性具有积极意义。In response to a series of problems arising from the lack of a unified naming specification for the many branches of the substation DC power system,this paper designs an integrated DC power feeder branch alarm tagging monitoring device.Long and short term memory network is used to replace the displayed branch fault names with the actual branch names in the field,which improves the efficiency of fault checking.The XML Schema protocol is used for statute mapping modeling to convert IEC104 statute and Modbus statute into IEC61850 statute,which enables the improved software to work in different insulation detection devices.Finally,the test experiments and the actual engineering application have verified that the upgraded insulation detection device can effectively identify the branch circuit where the insulation fault occurs,improve the efficiency of fault detection,and have positive significance for the DC system to improve maintenance efficiency and reliability.
