Abstract : Grounding system is very important for a substation in the sense of stability, safety and proper functionality of power system. There are various parameters which affect the grounding system performance such as grid depth, area of grid, horizontal conductors spacing, number of vertical ground rods, soil resistivity, level of fault current etc. This paper describes the performance of grounding grid in uniform soil by varying various design parameters, and calculating the effect using MATLAB tool. Grounding grid performance case study has been done on a 33 kV switchyard of hydropower station having uniform soil of resistivity using IEEE Std. 80-2000. Keywords - Grounding Grid, Grid Depth, Soil Resistivity, Grounding Grid Resistance, Touch Voltage, Step Voltage.
