Abstract：

Domestic and foreign scholars have conducted extensive research on the high-altitude electromagnetic pulse effect and vulnerability assessment of power systems, hoping to obtain the survival capability of power systems in high-altitude electromagnetic pulse environments and improve the operational reliability of power systems in response to extreme electromagnetic environments. Based on the current research status at home and abroad, this paper introduces the main threat characteristics of high-altitude electromagnetic pulse environment to the power system. It summarizes the research progress of electromagnetic pulse effects on key equipment in the power system from three aspects: experimental methods and platforms, key node simulation calculation, and effect threshold testing. It also elaborates on the main characteristics of vulnerability assessment methods and high-altitude electromagnetic pulse defense strategies in the power system at present. Finally, the existing problems in current research were summarized, and the main directions for future research were discussed.
