摘要
为分析高空核爆晚期效应对电力系统的影响,本文研究了高空核电磁脉冲晚期效应对电力系统稳定性影响。根据高空核爆晚期效应感应电流对电网元件的影响,建立了电网等效模型,得到了线路等效电压源,并计算了高空核爆炸晚期效应在电网上的感应电流,然后对晚期效应感应电流水平做出了评估,最后从断路器、自耦变压器两个方面分别考虑了偏磁对电网稳定性的影响因素。
In order to predict and analysis the risk that power systems suffer from late-time HEMP, in this thesis, this paper mainly studied on the impacts of late-time HEMP（HEMP E3 effect） on power grid stability. Based the induction current impact on grid components, equivalent models of components in power girds are established and equivalent voltage source of transmission lines can be obtained by the HEMP E3 effect standard waveforms, the induced currents level are estimated by calculating induced currents of late-time HEMP in the power grid,then analysis the impact of HEMP E3 effect Finally give a description of EHV circuit breakers, autotransformer and capacity to high GIC levels of stability of power systems.
