Modeling multi-layered soil by equivalent uniform and two-layer soil models in grounding applications
The soil models are crucial for calculating the performances of the grounding systems in electrical engineering. Usually, some approximations and simplified calculation procedures are used in engineering practice. These procedures are based on the assumption of the uniform soil model. However, real soil consists of more layers with different resistivities/conductances and thickness. The procedure of obtaining equivalent uniform and two-layer soil models using an optimization approach and numerical simulation is presented here. The grounding system used in the simulations is the single grounding rod as one of the simplest grounding structures. The proposed procedure does not require approximations and neglecting during calculation of the grounding system performances due to using the simulation tool based on numerical method. The equivalent soil model determination through the optimization is performed by using the co-simulation setup between the metaheuristic optimization and numerical simulation tools.
