چکیده مقاله
In this study, closed form solutions for broad band equivalent circuit of vertical rod is introduced To this end, at first using method of moments MoM , input impedance is computed in the frequency domain, then using vector fitting technique VF this frequency response is converted to rational functions and finally these functions are represented as equivalent circuit in time domain This process is carried out for a number of values of soil conductivity and rod radius and through these input output pairs soil conductivity and rod radius are inputs and each of lumped elements are outputs and then using adaptive neural fuzzy intelligent systems ANFIS , closed form solutions are achieved Consequently, the values of lumped elements of equivalent circuit are rapidly computed These solutions are very suitable when weather conditions are changing Also these models can be imported in transient solvers for transient analysis of power system
