Calculation Method for Geoelectric Field in Mid- and Low-latitude Area Based on Sparse Geomagnetic Data

  • 摘要: 强磁暴产生的地磁感应电流是诱发电力系统灾害性事故的关键因素,预防与控制地磁感应电流的必要途径是评估其在系统中的水平.掌握磁暴感应地电场的时空分布是评估所在区域电网地磁感应电流的基础,可为研究与防治电网磁暴灾害提供参考.在中国现有稀疏分布的地磁台观测数据基础上,建立了电离层等效球面元电流系统模型,并将其与复镜像法结合,建立了磁暴感应地电场和地磁场的计算模型.利用磁暴期间实测的地磁台站数据进行了计算,算例结果与平面波理论计算结果的对比证明了算法的正确性与有效性.计算结果可直接应用于电力系统的地磁感应电流计算,为分析电力系统磁暴灾害风险提供参考.
