【 摘 要 】

The influence of lightning on smart substation mainly includes three aspects, one of which is lightning striking the grounding body of adjacent smart substation and affecting smart components through space electromagnetic induction. When the lightning strike point of induction lightning is in the station, its radiation field is closely related to the location of the lightning strike point. It is necessary to verify whether it meets the electromagnetic compatibility level of intelligent components of lightning radiation field according to the actual situation. Firstly, the simulation model of intelligent component under the influence of induction mine is studied, and the steps of simulation modelling are given. On this basis, through derivation, the calculation method and corresponding formula of lightning current radiation field on the ground of perfect conductor are given in detail.
