摘要

笔者利用国际先进的图形化电磁暂态计算程序ATPDraw3.5进行500kV变电站雷击过电压的建模研究。在研究时将变电站和进线段结合起来

考虑雷击点的近雷区和远雷区、雷击杆塔绝缘子串冲击伏秒特性、线路上的感应过电压、工频过电压和进线段杆塔冲击接地电阻等因素的影响

从而对雷电侵入波系统进行建模分析。这为防护雷电过电压、保护电气设备提供了有价值的参考依据

为高压变电所雷击保护研究分析提供了有效的方法。

Abstract

This paper investigates modeling of lightning overvoltage on 500 kV substation by making use of the advanced software ATPDraw3.5

in which substation and incoming line are banded together as an object.The ATP modeling process of lightning surge system is analyzed considering such factors as near lightning strike area

far lightning strike area

impulse volt-second characteristic of lightning tower insulator string

induced overvoltage and power frequency overvoltage of the line

and tower impulse grounding impedance of incoming line

etc.The result may facilitate the prevention of lightning overvohage on high-voh substation.
