Method for determining lightning hazard distribution of power network
A method for determining a lightning hazard distribution of a power network, includes: deriving a shielding failure lightning hazard distribution of the power network and a back flashover lightning hazard distribution of the power network from the number of ground lightning in each grid and ranges of hazardous currents, and deriving a historical lightning hazard distribution of the power network from a lightning faults database of the power network and the grids; and determining the lightning hazard distribution of the power network by integrating the shielding failure lightning hazard distribution of the power network, the back flashover lightning hazard distribution of the power network and the historical lightning hazard distribution of the power network.
