Lightning Performance Evaluation of Italian 150 kV Sub-Transmission Lines
A significant majority of overhead transmission lines’ (OHLs) outages is due to backflashovers caused by direct lightning strikes: the realistic assessment of the lightning performance is thus an important task.

Simulation analysis of inrush current in no load closing of transformer in Hydropower Station
When the transformer is switched on without load, the magnetizing inrush current will be caused due to the saturation of the iron core, which may lead to the misoperation of the relay protection device, cause overvoltage and damage the insulation of the ...

基于ATP-EMTP仿真软件的输电线路雷击跳闸率多因素对比分析研究
通过电磁暂态仿真程序ATP-EMTP,建立了110 kV输电线路的雷击分析模型,主要包括:雷电流模型、杆塔模型、绝缘子串闪络模型等,该模型可以真实地反映雷电流在杆塔上的传播过程。然后分别利用规程法和ATP仿真法进行了计算与分析,得到线路在不同条件下的跳闸率;分析了杆塔高度、冲击接地电阻以及线路绝缘水平等因素对雷击跳闸率的影响。结果表明:在同等情况下,ATP-EMTP仿真计算的反击跳闸率略高于规程法的计算值;随着杆塔高度的降低、杆塔冲击接地电阻的减小、绝缘强度的增强,反击跳闸率减小。
