摘　　要：为准确、实时地实现对变电站设备绝缘状况的在线监测,论文提出总线式变电站设备绝缘状况在线监测方法。该方法通过现场监测模块中的监测设备获取变电站内设备运行状况信号,利用总线技术将信号传送至站端控制模块,并在控制模块中完成信号过滤和存储。然后通过综合相对测量方法,计算数据库中的信号数据诊断设备绝缘故障,将诊断结果发送至设备维修人员。测试结果表明:该方法可最大程度保证通信结果的稳定性和可靠性,在标准相对误差范围内完成采集信号的传输,准确获取变电站设备的相对介质的损耗值,并以此判断设备的绝缘状况。In order to realize the on-line monitoring of insulation condition of substation equipment accurately and in real time,a method of on-line monitoring of insulation condition of substation equipment based on bus is proposed in this paper.The method obtains the operation signal of the equipment in the substation through the monitoring equipment in the field monitoring module,and transmits the signal to the station control module by bus technology,and completes the signal filtering and storage in the control module.Then through the comprehensive relative measurement method,the signal data in the database is calculated to diagnose the insulation failure of the equipment,and the diagnosis result is sent to the equipment maintenance personnel.The test results show that this method can ensure the stability and reliability of communication results to the greatest extent,complete the transmission of collected signals within the standard relative error range,accurately obtain the loss value of the relative medium of substation equipment,and judge the insulation condition of the equipment.
