线路避雷器动作对雷击线路电磁暂态影响的仿真分析及其辨识

open access: yesDianci bileiqi
输电线路在易闪段的杆塔上装设有线路避雷器。针对在不同位置装设的线路避雷器,分析了雷电绕击导线闪络和未闪络两种情况下的站端雷击暂态电流行波响应。将站端暂态电流行波响应视为在避雷器动作后,雷电注入、绝缘子闪络故障附加激励和线路避雷器动作附加激励先后多次冲击叠加所引起的行波暂态响应,并以仿真和实测数据验证。由雷电流注入的初始行波在经过线路避雷器时引发避雷器动作,而后幅值发生一定程度衰减,并伴随一定振荡过程。从图像角度可以识别其衰减过程,利用最小二乘拟合无避雷器动作的暂态波形图 ...
