Abstract
This paper describes the development and testing of a software simulator to calculate the flow of Geomagnetically Induced Currents (GIC) in an electrical power transmission grid. In this paper, a new technique for mapping the location of transmission equipment for the purposes of GIC simulation is proposed. The DC modeling of autotransformers for the purpose GIC studies is discussed. The simulator models the electrical power system as an admittance matrix. GIC results for two study systems as obtained from the developed simulator are compared with those obtained from the Electromagnetic Transients Program (EMTP). Finally, the simulator is applied to the entire Hydro One 500/230 kV transmission system to predict GICs. This simulation will help Hydro One plan its mitigation strategies to protect against geomagnetic storms.
本文介绍了一个用于计算输电网中地磁感应电流(GIC)流动的软件模拟器的开发和测试。本文提出了一种用于GIC仿真的传输设备位置映射的新技术。讨论了用于GIC研究的自耦变压器的直流建模。仿真器将电力系统建模为导纳矩阵。利用该仿真器得到的两个研究系统的GIC结果与电磁瞬变程序(EMTP)得到的结果进行了比较。最后，将该仿真器应用于整个Hydro One 500/ 230kv输电系统，对GICs进行预测。这一模拟将帮助Hydro One公司制定缓解策略，以抵御地磁风暴。
