通过对第23太阳周几次磁暴期间广东岭澳500 kV电网的地磁感应电流（GIC）实测数据，2010年西北陕、甘、青、宁750 kV电网GIC的计算结果，以及500～1 000 kV电网结构特点和1859年超级磁暴强度的分析，阐述了极端空间天气对我国未来特高压、大规模电网安全的可能影响，提出了应对极端空间天气的研究建议。 

The measured data of GIC in Guangdong Lingao 500 kV power networks during the several magnetic storms at the peak of 23rd Solar Cycle, the GIC calculation results of 2010 750 kV planning power grid in Shanxi, Gansu, Qinghai and Ningxia, the structure and characteristics of power networks from 500 kV to 1 000 kV, and super magnetic storm in 1859 are analyzed in this paper. Through the analysis, the possible impacts of extreme space weather on the future UHV, large-scale power system security in China are discussed, and the research suggestions coping with the strong solar storms are proposed.
