| 摘 要： | 利用变电站接地网计算软件计算分析了一个实际变电站接地网系统。该系统结构比较复杂，利用设计规程手册中所提供的方法和其它近似解析计算公式难以对其进行准确分析计算。通过对该接地网的计算分析，表明了不同长度的垂直和水平接地棒、两层大地模型对接地电阻的影响，以及两个相近接地网的并联效果。

| Abstract: | A practical substation grounding grid is numerically simulated by a software. Analytical for mulas provided by any design menu and literture can not get reasonable results, since the grid is complicat ed. To reduce the grounding resistance the effectiveness pf horizontal and vertical grounding electrodes, and the two-layer earth model is investigated through the analysis of the grid: The connection of two grids located closely is also analyzed. |
