The lightning waves are one of the main over-voltage electric power equipment suffers, the lighting waves propagate on transmission line in the form of lightning current and lightning current of larger amplitude may bring great effect on insulation combining of adjacent substation and electromagnetic compatible stability. Statistics show that as one of the main factors leading to the failure of the insulation of electric power equipment, lightning over-voltage is becoming a major threat not be ignored to the safe operation of power network. Study on response characteristics of lightning wave on propagation plays a crucial role in insulation configuration. The lightning waves in substation are simulated based on ATP-EMTP in the paper, the lightning waves are simulated under different situations such as different types of original lightning waves, different lightning points, different collection position, and the wave characteristics are analyzed. The response characteristics of lightning waves are obtained on power system propagation.
