摘要

我们研究强烈的地磁风暴(Dst)。利用自组织图、统计和叠加历元分析等各种方法，我们表明，在强烈地磁风暴期间和之后，输电线路的故障数量有所增加。我们还研究了2010-2014年间电网故障数量的时间变化，发现电网故障发生的线性增长趋势可能与太阳活动有关。我们将这些结果与使用一维层状电导率地球模型计算的波兰地区地电场进行了比较。

Evaluating the relationship between strong geomagnetic storms and electric grid failures in Poland using the geoelectric field as a GIC proxy

We study intense geomagnetic storms (Dst . Using various methods such as self-organizing maps, statistical and superposed epoch analysis, we show that during and right after intense geomagnetic storms, there is growth in the number of transmission line failures. We also examine the temporal changes in the number of failures during 2010-2014 and find that the growing linear tendency of electrical grid failure occurrence is possibly connected with solar activity. We compare these results with the geoelectric field calculated for the region of Poland using a 1-D layered conductivity Earth model.
