Abstract This paper takes the main electrical wiring, equipment parameters, transmission tower and gantry model of the 500kV substation as the calculation input, and uses the electromagnetic transient program to simulate the lightning intrusion wave overvoltage. The maximum lightning overvoltage on the substation equipment under the typical operation mode are calculated. Afterimprovement measures are proposed. The maximum lightning overvoltage value on the transformer and other equipment is lower than the allowable value, meets the requirements of lightning protection.
