| 摘 要： | 地磁暴引起的地磁感应电流(GIC) 可能引起变压器直流偏磁, 对电网的安全稳定运行带来威胁, 远程实时监测GIC对电网的GIC防御具有重要的指导意义。设计了一种基于云服务器的电网GIC远程监测系统, 数据采集终端实时采集变压器中性点的GIC, 多监测点数据经GPRS分端口发送至云服务器的内网进行存储, 用户可通过云服务器的公网IP远程访问并对数据进行绘图、下载等处理, 实现了电网GIC数据的实时发布与共享。结合空间天气的预测数据, 还可以初步实现GIC的预警。对系统的数据采集终端以及基于云服务器的监测软件平台两大模块进行了实验室及变电站现场测试, 测试结果表明该系统实现了设计要求, 满足功能需求。

| Abstract: | The geomagnetic induced current (GIC) caused by geomagnetic storm may result in DC bias of the transformer, which poses threats to the safe and stable operation of the power grid.Remote real-time monitoring of GIC can provide important reference for grid GIC defense.Based on cloud server, a GIC monitoring system is designed.The data acquisition terminal collects the transformer's neutral point GIC in real time.Using GPRS, the data from multiple monitoring points are sent by different ports to the internal network of the cloud server for storage.It is possible for users to access the data remotely through the public network IP of the cloud server and process data via drawing and downloading.The real-time release and sharing of GIC data has been realized via this system.Combined with the forecast data of space weather, the early warning of GIC is preliminarily realized.Tests of the data acquisition terminal of system and the monitoring software platform based on the cloud server in the laboratory and substation field show that the system has achieved the design requirement and meets the functional requirements. |
