Abstract
A lightning shielding failure risk assessment method for a power transmission line based on three-dimensional laser point cloud data includes reclassifying three-dimensional laser point cloud data of a power transmission corridor; acquiring lightning activity parameters for the power transmission corridor; determining wire, ground wire, and ground point cloud striking distances; plotting three-dimensional wire, ground wire, and ground shielding arc surfaces in the preprocessed three-dimensional laser point coordinate system; performing orthogonal projection of the plotted three-dimensional shielding arc surfaces to obtain two-dimensional exposed arc surfaces and determining the areas of the two-dimensional exposed arc surfaces; and looping to calculate the areas of the exposed arc surfaces at different lightning incidence angles and different lightning current amplitudes; and determining a line trip rate based on the lightning strike density, the lightning incidence angle probability distribution function, and the lightning current probability distribution function.
