Abstract

To fully utilize the big data accumulated by the lightning positioning system to provide lightning protection services, combined with the lightning fault characteristics and typical tower models of various voltage levels of transmission lines in Qinghai Power Grid, a simulation calculation study on typical towers of transmission lines above 110kV was carried out. ATP-EMTP was used to build a model to simulate and calculate the range of dangerous lightning current for counterattack, and the electrical geometric model method considering the strike distance coefficient and ground inclination angle was used to calculate the range of dangerous lightning current for bypass. At the same time, based on the dangerous lightning current range and average annual lightning situation in Qinghai region, the risk distribution map of lightning strikes in Qinghai region is drawn according to four voltage levels: I, II, III, and IV. This provides technical support for the design of lightning protection engineering in Qinghai power grid and the prevention and reduction of lightning disasters.
