Influence Factors of GIC in Two Substations of Geomagnetic Storm on 11 October 2021

  • 摘要: 近年来中国相继监测到地磁暴侵害电网、铁路轨道电路和油气管道系统产生的地磁感应电流(Geomagnetically Induced Current,GIC)数据,但是目前实测的GIC数据还相对较少。根据2021年10月9日日冕物质抛射事件(CME)产生的Kp指数为6的地磁扰动(Geomagnetic Disturbance,GMD)数据,500 kV阿拉坦变电站(48.7°N,116.8°E)和上河变电站(33.4°N,119.2°E)及输电系统的参数,分析了2021年10月11日地磁暴期间在两座变电站监测到的GIC数据以及输电系统参数对GIC量值的影响。结果表明:地磁暴在500 kV上河变电站产生的GIC比阿拉坦变电站GIC量值相对较大。分析结果说明,在这次磁暴事件中,输电线路导线电阻是影响变电站GIC的主要因素。
