Good performance of grounding impact is an important precondition to ensure the safe and stable operation of the line.By using the improved vector matching method to numerically fit the frequency-dependent impedance of the tower grounding resistance,based on the frequency-domain characteristics obtained by the improved vector matching method.Equivalent circuit model under device impact condition is used to compare and analyze the frequency domain response calculated by CDEGS and equivalent circuit model based on the experimental data and verify the correctness of this method under the impact condition based on the difference of response results.
