This paper proposes a novel method for calculating the lightning transient response in grounding grids. the analytical formulas are given for estimation of the electrical parameters of grounding branches and the π -type circuits are used to represent the branch segments in a piecewise manner. Based on the π type circuits, the equivalent circuit model is set up for the grounding grid. In order to take account of the influence of soil breakdown on the lightning transient response, the soil breakdown is simulated as a simplified ionization zone around the grounding branch. The efficient radius of the grounding branch can be determined in terms of the critical value of soil ionization gradient, which is then applied to the lightning transient calculation. Also, the proposed method has been validated by comparing the calculated results with the measured results.

介绍了接地网中雷电暂态的计算方法。该方法给出了接地分支的电气参数计算公式 ,采用π型电路表示接地分支的分段单元 ,建立了接地网的等效电路模型。为了计及土壤放电击穿对雷电暂态响应的影响 ,接地体周围的土壤放电击穿被简化模拟为单一的游离区 ,根据土壤的临界击穿场强估算出雷电暂态计算所需的接地分支有效半径。计算结果与实测结果比较 ,两者基本吻合
