Design of Geomagnetic Induction Current Monitoring and Early Warning System Based on Cloud Server

The geomagnetic induced current (GIC) caused by geomagnetic storm may cause DC bias of the transformer, which poses a threat to the safe and stable operation of the power grid. Remote monitoring of GIC can provide important reference for grid GIC defense. This paper designs a GIC monitoring and early warning system based on cloud server. It can not only monitor the neutral GIC of the transformer in real time, but also combine the forecast data of space weather to achieve the purpose of early warning, thus ensuring the safe operation of the power system. Aiming at the unreliability of data transmission in the process of remote monitoring data transmission, a processing method based on communication fault detection, local storage and remote transmission is proposed, which improves the real-time and reliability of the system.
