This scientific document presents the analysis and optimization of the mesh of the grounding system of a 69 / 13.8 kV substation in Ecuador. The mesh is made up of horizontal and vertical conductors connected with vertical electrodes buried under the ground of the substation. The function of the structure is to effectively dissipate the high short-circuit currents generated in the system. The objective is to determine the safety parameters of the ground mesh by comparing the mesh design analysis using the IEEE method and the Finite Element Analysis (FEM) method. These two methods are used differently to determine the electrical parameters of the ground mesh, the step voltage and touch voltage, the number of horizontal conductors, the number of vertical conductors, the number of electrodes, and the earth resistance of the Substation. ETAP 16.0 software is used for analysis. First, the maximum short-circuit current of the substation of 69 / 13.8 kV is determined. Second, the analysis is performed to determine the input and output parameters of the ground mesh structure using the IEEE and FEM methods. It ends with the results of the optimization of each of the specific methods, making a comparison of the two methods used and giving a recommendation regarding the best method for the design of the ground mesh.

Appropriate design of a substation grounding grid keeping in view of safety of equipment and personnel working area in or walking close to the substation is of great importance. Several steps are involved to design and developed a safe, effective and optimized grounding grid. IEEE Standard 80-2000 explains the terminologies, definitions, formulas and act as an important guide for substation grounding grid design. To date a number of substations grounding grid design intelligent software have already been developed by engineers of many commercial enterprises which takes well care of safety, reliability, continuity of services and optimization of the design. Such a software, e.g., Electrical Transient Analyzer Program (ETAP) has been utilized in this study which has achieved optimization in substation grounding grid design ensuring safety of personnel and equipment. The study utilized the Finite Element Method (FEM) of Ground Grid System (GGS) module of ETAP in combination with Sverak's variable space technique and showcased that 63.88% copper saving of ground rods could be achieved in comparison with a reference study of substation grounding grid. The method thus has become a very effective tool in substation grounding grid optimization.
