摘要
我国电网中已发现多次较大幅度的地磁感应电流(GIC)侵扰事件,随着电网规模的增大,存在产生更大GIC的可能性。针对基于变压器中性点电流的GIC在线监测系统,运用计算机技术、通信技术和网络技术,实现对各检测点的中性点电流数据的远程采集、监测、处理。为深入研究我国电网受磁暴影响的可能性及其相关因素提供科学依据。
Geomagnetic induced currents（GIC）of large magnitude have been found several times in power grids in China. With the development of power grid in China, larger GIC may be present in the power grids. Aiming at monitoring system for GIC of power grid, and using computer technology, communications and network technology, the various points of the GIC detection, remote data collection, monitoring, and treatment are achieved, which provides a scientific basis for in-depth study of the effects of magnetic storms and related factors on power grid in China.
