Research on Operation State Monitoring of Substation Isolation Switch Based onMulti-source Data Integration

为了使智能变电站运行维护的能力得到提高,对隔离开关机械状态分析,就要对变电站隔离开关运行状态进行监测。对不同机械状态下隔离开关的运行进行分析,对机械状态信号进行降噪,并且提取机械状态的振动信号特征,从而自动监测智能变电站隔离开关运行状态。对文章方法进行试验,表示文章方法的监测准确性较高,能够缩短机械状态的监测时间和成本,使智能变电站运维能力得到提高。

In order to improve the ability of intelligent substation operation and maintenance,it is necessary to monitor the operating state of the isolation switch in the substation by analyzing the mechanical state of the isolation switch.The operation of the isolation switch in different mechanical states is analyzed,the noise reduction of the mechanical state signal is carried out,and the vibration signal characteristics of the mechanical state are extracted,so as to auto-matically monitor the operating state of the isolation switch in smart substation.The experimental results show that the method in this paper has high monitoring accuracy,can shorten the monitoring time and cost of mechanical condi-tion,and improve the operation and maintenance ability of intelligent substation.
