This article deals with the model of a high current injection system associated with its electrical generation–transformation–distribution chain able to reproduce differential or common-mode parasitic currents and voltages induced by the coupling between a nuclear electromagnetic pulse radiation on a global electrical network. Due to the quite complexity of the current injection system, the chosen modeling approach was to use the well-known equivalent Thevenin generator. Because of several hundreds of amperes and volts of current and/or voltage generated and their relatively large spectral occupancy of some tens of megahertz, the measurement of currents and voltages needed to build the model, were carried out with adequate sensors and equipment. Once the model built, the generators have been integrated into Spice circuit simulation tool in order to predict the differential and the common- mode currents and voltages induced at the input of switch-mode power supplies and, for later studies, at some different nodes.

用于磁化率研究的电流注入系统建模

本文讨论了与其发电-变电-配电链相关的高电流注入系统模型，该系统能够重现由全球电网上的核电磁脉冲辐射之间的耦合引起的差分或共模寄生电流和电压。由于当前注入系统相当复杂，所选择的建模方法是使用众所周知的等效戴维宁发生器。由于产生了数百安培和伏特的电流和/或电压，以及它们相对较大的数十兆赫的频谱占用，建立模型所需的电流和电压的测量是使用足够的传感器和设备进行的。模型建成后，
