Abstract :
This paper focus on earth potential maldistribution when substation is stroke by lightning. ATPDraw is used to analyze lightning transient effect of earthing network. First set up unit model of earthing body based on general mathematical model of single earthing body. Then establish simulation model of practical earthing network followed a 220 kV substation lightning transient effect is simulated and calculated, then the reconstruction measure is put forward based on simulation result.
