Abstract :
The high current induced by solar storm, namely the geomagnetically induced current (GIC) has been discovered in Jiangsu and Guangdong power grids as well as in other provincial power grids with the development of the long-distance power transmission system in China in recent years, which have resulted in some latent influence on these power grids. Based on the structures of EHVAC in Sichuan, the preliminary estimate for the GIC level in Sichuan power grid had been made by use of the data of ground electric field induced by the typical solar storm with MATLAB simulation software. The results show that the GIC influence on Sichuan power grid under the strong magnetic storm is not optimistic; it should pay a sufficient attention to this problem.
