| 摘 要： | 基于长空气间隙的放电理论建立雷电屏蔽的先导发展模型，利用该模型进行特高压直流线路雷击过程仿真，并计算文献中给出的实际线路的雷电屏蔽性能。仿真计算结果表明：特高压线路存在明显的“回头雷击”现象；利用雷电屏蔽模型计算的结果较电气几何模型计算的结果更接近实际运行数据，可用于工程实际仿真计算。

| Abstract: | A progression model is built based on discharge theory of long air gap.By use of this model,lightning strike on UHV transmission lines is simulated and lightning shielding performance of the lines given in the references is calculated.The simulation result shows that there are obviously returning strikes on UHV lines;the calculation result by means of lightning strike model is closer to the practical operating data than that by electric geometric model,and it can be put into simulation calculation. |
