| 摘 要： | 以某变电站发生的雷击事故为例,以电磁暂态程序ATP-EM TP为计算平台,搭建了雷击输电线路雷电侵入波侵入变电站的计算模型。采用ATP-EM TP对站内各电气设备上可能出现的最大雷击过电压值进行了定量计算,分析了雷击造成事故的过程和输电线路绝缘变化对侵入变电站雷电过电压的影响,并提出了防雷改进措施。计算结果表明:输电线路绝缘变化对变电站内电气设备上的过电压幅值基本没有影响。

| Abstract: | Based on a lightning accident in a substation,a calculation model for lightning intruding waves intruding substation has been established based on the platform of electro-magnetic transient program.The possible maximum lightning over-voltage in the electrical equipment of the substation has been quantitatively calculated.The lightning accident progress and the influence of transmission line insulation changing on substation intruding lightning over-voltage have been analysed and the anti-lightning measurements have been proposed.The calculation result shows that transmission line insulation change has little impact on the amplitude of over-voltage in the equipment of the substation. |
