Abstract

The invention is applicable to the technical field of electric power operation and maintenance, and provides an overhead line lightning protection efficiency evaluation method and device, and the method comprises the steps: obtaining a plurality of lightning protection efficiency indexes of an overhead line; Respectively calculating weights corresponding to the plurality of lightning protection efficiency indexes according to the number of the plurality of lightning protection efficiency indexes; And according to the plurality of lightning protection performance indexes and weights, calculating a lightning protection comprehensive evaluation index of the overhead line. According to the overhead line lightning protection efficiency evaluation method and device, the comprehensive lightning protection evaluation index of the overhead line is calculated according to the plurality of lightning protection efficiency indexes of the overhead line and the weight of each lightning protection efficiency index, so that the comprehensive and effective evaluation of the lightning protection efficiency of the overhead line is realized.

Description

technical field [0001] The invention belongs to the technical field of electric power operation and maintenance, and in particular relates to a lightning protection performance evaluation method and device for an overhead line. Background technique [0002] Transmission lines such as overhead lines will cause overvoltage when struck by lightning, which may cause tripping of relay protection actions, cause transmission line outage, and cause grid accidents and economic losses. With the development of power system, accidents caused by lightning strikes on overhead lines are also increasing. As an important means to prevent the risk of power grid operation and an important way to improve the operation level of equipment, the investment in the improvement of lightning protection technology for overhead lines is increasing year by year. Before and after the technical transformation of lightning protection, it is necessary to conduct a comprehensive, effective and reasonable eval...
