摘　　要：针对变电站设备监控的需求,设计了一种基于物联网技术和LoRa通信的22kV配电变压器故障监控系统。该系统由安装在变压器处的传感器节点、数据汇聚的网关站和ThingSpeak云服务器三部分组成。通过在变电站布置电压传感器实时采集数据,利用LoRa模块进行长距离无线传输,结合4G模块发送短信警报,并通过Wi-Fi上传数据至云平台,实现了对变电站设备的实时监控和故障预警。系统在实际变电站环境中进行了为期一个半月的实地测试,结果表明该系统能够准确检测和记录各类电力故障,并及时发出警报。研究成果为变电站设备的远程监控提供了一种低成本、高效率的解决方案,有助于提高电力系统的稳定性和运行效率。A 22 kV distribution transformer fault monitoring system based on IoT technology and Lo Ra communication was designed to meet the needs of substation equipment monitoring.The system consists of sensor nodes installed at the transformer,a gateway station for data aggregation,and the Thing Speak cloud server.Voltage sensors are deployed in the substation to collect real-time data,which is transmitted over long distances using Lo Ra modules.Alerts are sent via SMS using a 4G module,and data is uploaded to the cloud platform through Wi-Fi,enabling real-time monitoring and fault warning of substation equipment.A field test lasting one and a half months in an actual substation environment demonstrated that the system accurately detected and recorded various power faults and promptly issued alerts.The results provide a low-cost,high-efficiency solution for remote monitoring of substation equipment,contributing to improved stability and operational efficiency of the power system.
