Investigation of lightning protection of open switchgears of power stations and substations

Abstract

The development of methods and algorithms for calculating elements of protection of energy facilities is always one of the
most important scientific and technical problems. Remains relevant as the development of new technical solutions, as well as the improvement of the regulatory framework. The indicated tendencies are also valid for the lightning protection of power stations and substations. The purpose of this study is to review the existing methods for determining the parameters and elements of lightning protection using the example of calculating a typical substation. As a result of the study, the methods of designing and determining the effectiveness of lightning protection of power stations and substations are considered. The results of the calculation of the lightning protection of the open switchgear of a transformer substation 110/10 kV are presented. The results of the study can be used to develop algorithms for determining the parameters of lightning protection, as well as software for automated calculation of the protection of open switchgears of power stations and substations from direct lightning strikes.
