摘要
复镜象法是一种模拟计算变电站接地网的新方法 ,该方法适用于多层大地模型中任意结构接地网的模拟。但在分析大型地网时 ,由于接地导体数n较大 ,接地电阻的互导矩阵阶数为n ,数据待求量则为n2 。这是一个很庞大的数据计算量 ,而提出的对称复镜象法则可以大大减少数据输入量 ,并用这种方法分析了几个实际的接地网 。
When the complex image method in used to simulate electromagnetic fields in multiple layer media for large scale grounding grids with lots of conductors if the order of the mutual resistance matrix is n , the number of the data requested will be n 2 . The number of the input data can be more decreased with the symmetric complex image method presented in the paper than that with the complex image method. The results of a few examples with the presented method are satisfactory.
