A Method of Monitoring the Status of Dual Power Backup in Substation Based on Internet of Things

常规的变电站双电源备自投状态监测方法多数采用网损平衡异动分析原理设计而成。实际应用过程中,在变电站规模较大的情况下,备自投状态监测定量误差较大,监测精度较低。为改善这一问题,开展基于物联网的变电站双电源备自投状态监测方法研究。采集蓄电池的各项参数,对变电站双电源备自投蓄电池进行巡检设计。利用物联网技术,实时监测备自投绝缘状态的动态变化,及时排除双电源备自投装置接地故障隐患。在此基础上,对备自投状态监测数据库进行建模设计,存储、调取并管理监测数据,实现复杂的变电站双电源备自投状态监测数据表间查询功能。分析实验结果可知,按照提出方法监测双电源备自投状态,监测定量误差较低,能够准确反映变电站双电源备自投状态的实时变化。

Most of the conventional methods for monitoring the status of dual power backup in substation are designed based on the principle of network loss balance transaction analysis.In the actual application process,when the substation is large in scale,the quantitative error of monitoring the status of backup backup is large and the monitoring accuracy is low.In order to improve this problem,the state monitoring method of dual power backup in substation based on the Internet of Things is studied.Firstly,the parameters of the battery are collected,and the inspection design is carried out for the self-throwing battery of the double power supply in the substation.Secondly,the use of the Internet of Things technology,real-time monitoring of the dynamic changes in the insulation state of the standby self-propelled device,in time to eliminate the potential ground fault of the dual power standby self-propelled device.On the basis of this,the model design is carried out to store,retrieve and manage the monitoring data,and the query function between the monitoring data tables of double power supply in substation is realized.The experimental results show that the quantitative error of the monitoring method is low,and it can accurately reflect the real-time change of the state of the dual power supply backup.
