摘要
雷电流数学模型的选择及仿真分析,对感应雷过电压的研究具有重要的意义。对目前感应雷过电压研究领域应用广泛的双指数函数模型,Heidler函数模型,脉冲函数模型3个函数模型,从雷电流的全波、波头两个方面做仿真分析,一阶导数做理论分析,并引入更加精确的双Heidler模型,进行对比分析。总结4种模型各自的优缺点,说明双Heidler模型的精确性及可行性,有助于雷电流模型的选择及感应雷过电压的进一步研究。
The selection and simulation analysis of the lightning current mathematical model is of great significance to the study of induced lightning overvoltage. The two exponential function models,Heidler function model and impulse function model,which are widely used in the research field of induced lightning overvoltage,are applied to simulate the full-wave and wave-head of the lightning current. The first-order derivative theory analysis,and the introduction of more accurate double Heidler model for comparative analysis. The advantages and disadvantages of the four models are summarized,and the accuracy and feasibility of the dual Heidler model are illustrated,which contributes to the selection of the lightning current model and the further study of the induced lightning overvoltage.
