摘要
根据雷电流的特点,结合雷电流的相关参数,主要对三种雷电流数学模型,即双指数函数模型、Heidler函数模型和脉冲函数模型,利用Matlab软件进行了仿真分析,得出了三种模型间的特性异同性及其各自的适用范围,这有助于进一步研究雷电特性、减小雷电危害。
According to the characteristics of lightning current, and combining with some parameters of lightning current, three main lightning current mathematic models such as bi-exponential function model, Heidler model and impulse function model were analyzed by MATLAB and distinctions among different models and their applicability were obtained, which is helpful in doing research on characteristics and reducing the harm effects of lightning.
