Abstract

To ensure safe and reliable operation of the substation, avoid the equipment damage caused by lightning wave invasion, which threats the safe operation of power system, it is necessary to research the influence factors of the substation lightning overvoltage and lightning protection measures. Taking a 500kV HGIS substation as the research object, a simulation model is established. Based on EMTP-ATP, this paper simulates the lightning striking the top of the tower and back-flashover occurring at the coming line of transmission line. Based on the principle of single variable, the factors which affect lightning overvoltage amplitude was studied, the change rule of amplitude was summarized. By configuring the quantity of arrester and the location of installation, through simulation, it determined that installing arresters at the line entry and GIS bus is the most reasonable lightning protection scheme.
