Abstract

The invention discloses a lightning protection method and apparatus for a power transmission line. The lightning protection method for the power transmission line comprises: obtaining lightning parameters of the power transmission line; according to the lightning parameters, calculating a lightning protection degree of each tower foundation of the power transmission line; and according to the lightning protection degree, setting a lightning protection mode of the power transmission line. Through the lightning protection method and apparatus, the problem of low lightning protection performance of a power transmission line in the prior art is solved, so that the effect of improving the security and stability of the power transmission line is achieved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a lightning protection method and device for power transmission lines. Background technique [0002] In the prior art, the lightning risk assessment of transmission lines mainly relies on the calculation of the lightning resistance level and lightning trip rate of the transmission line, and generally only calculates the lightning trip rate of several typical towers in the line under typical topography and traditional lightning parameters. When evaluating the lightning flashover characteristics of the entire line, the calculated lightning trip rate of typical towers is generally only weighted and averaged according to the ratio of various topography and landforms in the line corridor. The relative risk of tower lightning flashover makes it impossible to accurately protect the transmission circuit against lightning, resulting in low lightning protection performance of the t...
