摘要
主要研究雷击电流通过地网对二次电缆产生的干扰。根据电缆的几何参数,计算电缆的阻抗参数,形成阻抗参数矩阵,建立分布参数模型和波动方程,通过相模变换将其解耦,然后转化成电气上彼此独立的一维波动方程,用基于Bergeron的特征线法ATP-EMTP进行暂态计算。
This paper mainly studies electromagnetic produced when current by lightning through the net interfere with the secondary cable system And to get impedance parameter of cable based on geometric parameter of cable, and to establish the distributed parameter model of the secondary cable and wave equation, and to use ATP--EMTP to calculate interference potential difference between the core wire and the shielding sheath based on Bergeron.
