Abstract: In order to fully understand the characteristics of lightning activity and thereby supply important reference for plan and construction of the Anhui Grid as well as lightning protection design, massive detection data from 2005 to 2009 gained by Anhui Lightning Detection Network are statistically analyzed by the grid method in this paper. The time and space distribution of lightning activity and distribution of cloud-ground flashes current amplitude in Anhui province are presented. On the basis of the results, the lightning performance of shielding failure of a typical transmission line is studied with lightning parameters recommended by regular method compared with that with statistical lightning parameters. The results show that the lightning activity in Anhui province mainly happens in south-east areas. In addition, the statistical ground flash density is higher than that recommended by regular method and the median current of the cumulative probability fitting expression obtained in this paper is lower than that of the fitting expression format adopted by IEEE. The shielding failure rates calculated with statistical lightning can better meet the operational experience.
