Abstract

In this paper

using the ATP transient simulation software

modeling the lightning protection of the typical substation system at all levels

the lightning overvoltage

transfered to the substation of secondary system

is calculated.It is put forward that: install the protective gap at incoming line side

install lightning arrester at transformer high and low voltage side

low voltage power supply system use three levels of lightning protection of the power distribution system the lightning protection at all levels

and simulate the cooperate situation.The computer aided basis is provided by the model for the selection of lightning protection components and the lightning protection each level

and it has certain directive significance for lightning protection insulation coordination.
