摘要：

According to the method of moment, an effective electromagnetic approach for the substation's grounding grid in high frequency domain is presented. An efficient method based on the generalized pencil-of-function method is developed to calculate the generalized Sommerfeld integral With the method, the value of Green's function in a two-layer medium can be obtained quickly and accurately. The number of unknown variables of the moment method is small As the dipole antenna theory is introduced, the frequency of the injected current to the grounding grid can vary in a large scale. The method can be used to analyze not only the performance of the grounding grid, but also other grids located under the earth, in the air or penetrating a lossy interface. The computational results are in good agreement with those obtained by other method.
