| 摘 要： | 磁暴产生的地磁感应电流(GIC)直接损伤变压器和间接干扰继电保护等设备,强磁暴可能威胁到电网的安全运行。为探明磁暴对沿海核电站变压器的影响,对第23太阳周峰年强磁暴侵害广东岭澳核电站、江苏上河变电站的GIC测量数据,以及西北陕甘青宁750 kV电网计算数据进行统计分析,研究沿海核电站与内陆变电站变压器GIC大小及其差异原因。结果表明,由于受海岸效应现象的影响,沿海核电站的变压器更容易遭受磁暴的侵害。在此基础上,对极端磁暴的可能危害、灾害风险以及沿海核电站的磁暴灾害进行评估,并建议核电站选址和变压器选型时应评估磁暴的影响。 |

| Abstract: | The geomagnetically induced current(GIC) caused by magnetic storm would damage transformers directly and disturb relay protections or some other equipments indirectly,and strong magnetic storm could threaten the security of power system.For verifying the magnetic storm impact on the transformers in coastal nuclear plants,a mass of GIC data was collected and statistically analyzed,which included the measured GIC data in Guangdong Ling'ao nuclear power plant and Jiangsu Shanghe substation and the calculated G... |
