Abstract

This paper investigates the lightning over-voltage process of a 1000 kV ultra-high voltage(UHV) gas insulated switchgear(GIS) substation by the help of one electromagnetic transient simulation software, Electromagnetic Transients Program-Alternative Transients Program (ATP-EMTP). Taking the near lightning stroke for example, the simulation model is built with a substation, some incoming lines and their relevant line terminals. Firstly, it studies different influences of various substation operation modes, line voltage, and impulse grounding resistance, etc. Secondly, in order to identify the over-voltage distribution and variation of the electrical substation equipments (mainly transformers), it studies the over-voltage influence generated by lightning invasion wave in the whole system. Finally, based on comprehensive simulation and theoretical analysis, some suggestions are proposed to restrict the lightning over-voltage.
