| 摘 要： | 在ATP的LCC中提供了两种电缆仿真模型:一种是护套理想接地的电缆模型;另一种是护套经接地电阻接地的电缆模型.通过加入雷电波冲击和改变电阻长度的方法来研究线路的过电流和变压器的过电压,从而得出两种模型的差别.经过对比分析,得出一种能够反应实际情况的电缆仿真模型.

| Abstract: | There are two cable simulation models of sheath at both ends grounded in the LCC of ATP.One is the sheath ideal grounded,and the other is the sheath grounded through resistance.The paper has researches the over current of line and over voltage of transformer through the electrical source of lightning shock and the changing length of cable,to obtain the difference between the two models.After the comparative analysis,this paper obtains a cable simulation model which reacts to the actual situation. |
