摘要

本文在MATLAB/SIMLINK环境下对通信塔接地系统进行了雷击时的数学建模与仿真。采用传输线模型对铁塔和接地系统进行模拟。研究了雷电条件下的不同接地方式,如竖杆接地、水平矩形接地以及两者结合接地。考虑并比较了不同土壤条件和土壤电阻率的影响。结果是在放电点和其他选定点的电压、电流和阻抗变化。

Simulink based modelling and simulation of the communication tower grounding system
The paper presents the mathematical modeling and simulation of communication tower grounding system during lightning strike under MATLAB/SIMLINK environment. The transmission line model is used to simulate both the tower and the grounding system. Different methods of grounding such as vertical rod, horizontal rectangular grounding and the combination of the two are studied under lightning condition. Different conditions of the soil and the effect of soil resistivity are considered and compared. The result is voltage, current and impedance variations at the point of discharge and other selected points.
