摘要
通过计算机模拟软件对一个结构比较复杂、利用设计规程手册和其它近似解析公式难以准确分析计算的实际变电站接地网系统进行计算分析，给出了不同结构、不同长度的接地体、两层大地模型对接地电阻的影响。
A practical substation grounding grid is analysed by a computer simulation program with numerical calculation techniques. Since the grid possesses a complicated structure, analytical formula can hardly give reasonable results. In this paper the influence of grounding grid with different structure and length on grounding resistance is presented, the influence of two-layer earth models on grounding resistance is also given. The effect of two adjacent parallel grounding grids is introduced.
