Method for drawing distribution map of lightning stroke tripping risk

The invention discloses a method for drawing a distribution map of lightning stroke tripping risk. The method comprises: obtaining power grid parameters and lightning stroke parameters of a to-be-analyzed region; dividing the to-be-analyzed region into a plurality of grids; counting cloud-to-ground lightning density of each grid; calculating lightning stroke tripping risk values of power grid circuits of the to-be-analyzed region; grading the lightning stroke tripping risk values of the power grid circuits of the to-be-analyzed region and performing visualization processing, to obtain a finaldistribution map of lightning stroke tripping risk. Through historical operation data of the power grid and lightning stroke historical data, the to-be-analyzed region is divided by grids, and the lightning stroke tripping risk value of each grid is calculated by using a scientific and reasonable calculation method, to obtain the distribution map of lightning stroke tripping risk. Therefore, the method can accurately and
