短路故障下接地网电位分布的讨论

Discussion on potential distribution of grounding net under short circuit failure

对一个实际的变电站地网在短路故障下的电位分布进行了讨论。通过对短路故障下地网中的电位分布和地表面的电位分布在各种情况下的分析计算得到了一些可应用于工程实际中的结论 。

Using finite element method (FEM),the potential distribution of an actual substation grounding net under short circuit failure was discussed.Both the potential distribution in the grounding net and that of the soil surface under different condition were discussed.Some useful conclusions were drawn through careful calculation and comparison.As an effective method for engineering analysis,the FEM can be applied to potential distribution research of grounding net under any short circuit failures.
