Abstract

The lightning overvoltage protection program for enter line side and feeder side of 220 kV traction transformer substation of passenger dedicated railway line were researched.The lightning overvoltage simulation model of the traction transformer substation was established with ATP-EMTP,and the various lightning arrester setting methods were simulated and analyzed.The optimal arrester setting method was selected through simulation,that is for the enter line side a group of arrester respectively set in both sides of cross connection and in front of transformer,or feeder side,a group of arrester was respectively set in the joint of cable with over head contact line and in the GIS switch cabinet.
