摘要

针对低压设备事故频繁发生的问题

使用电磁暂态计算程序ATP-EMTP（ATPDRAW）就某110 kV变电站雷击进线段杆塔塔顶落雷引起的过电压进行建模与仿真

通过建立系统中配电变压器、电源线、避雷器、接地系统等相关元器件的数学仿真模型

进行了雷击点、运行方式和杆塔接地电阻的比较

讨论了绝缘配合裕度计算等重要因素对雷电过电压的影响。

Abstract

Aiming at frequent faults existing in low voltage equipment

ATP-EMTP（ATPDRAW） was used to model and simulate overvoltage caused by lightning on the top of incoming transmission tower in one substation.Through establishing the digital simulation model of distribution transformers

power lines

arresters

grounding system

and relevant components

lightning points

operation modes

and tower grounding resistance were compared and the influence of important factors such as insulation corporation margin on lightning overvoltage were discussed.
