关于变电站防雷保护数字模拟方法的讨论

Discussion on Digital Simulation Methods of Lightning Incoming Surge Protection for Substation

在变电站雷电侵入波保护数字模拟中，铁塔馍型、绝缘子闪络模型的模拟方法以及雷击地点的选择等对于因变电站近区雷击形成的雷电侵入波的幅值和波形会带来很大的影响，探讨采用不向模拟方法对上述模型模拟结果带来的影响、计算结果差异的原因进行了分析。

In digital simulation of lightning incoming surge protection for substation, the simulation methods of towcr model and insulator strings flashovcr model, the scloction of light-ning strike spot and so on give the great influcnces on the magnitute and thc wave shape of the lightning surges coming into the substation.This paper studics the influcnce of somc abovc-mcn-tioncd clemcnt modcls with diffcrent simulation methods on simulation rcsults, and analyses the cause which brings about diffcrcnce in isim ulation rcsults.
