【摘要】 强电磁脉冲干扰会对现代复杂电网带来极为有害且不可恢复的损害,可能导致电网的大范围长时间停电。为了更好地对复杂电网进行防护,首先需要研究和掌握强电磁脉冲对复杂电网的影响。本文运用类Kuramoto动力学模型对复杂电网进行建模,加入高空核电磁脉冲作为电网干扰源。高空电磁脉冲通过传输线耦合产生瞬态高电压,对变压器造成破坏从而影响全电网。通过对电网的各个节点频偏情况进行分析,可以得出高空电磁脉冲对复杂电网同步稳定性的影响。更多还原

【Abstract】 The high magnitude electromagnetic pulse when interact with modern complex power grid,has the competence to produce extensive and long eternal disruption.In order to have a better protection,it is necessary to study and master the influence of strong electromagnetic pulse on complex power grid.In this paper,the complex power grid is analyzed by using a dynamical model based on Kuramoto-like oscillators,and the high-altitude electromagnetic pulse(HEMP) is added as the interference source of the power grid.The HEMP generates transient high voltage through the transmission line coupling,which damages the transformer and affects the whole power grid.This presentation will analyze the frequency offset of each power network node,and will reveal the influence of HEMP on synchronous stability of complex power grid.更多还原
