摘 要:The primary aim of the power system grounding is to safeguard the person and satisfying the performance of the power systemtomaintain reliable *** equal conductor spacing grounding grid design,the distribution of the current in the grid is not ***,unequal grid conductor span in which grid conductors are concentrated more at the periphery is safer to practice than equal *** paper presents the comparative analysis of two novel techniques that create unequal spacing among the grid conductors:the least-square curve fitting technique and the compression ratio techniquewith equal grid configuration for both square and rectangular *** Swarm Optimization(PSO)is adopted for finding out one optimal feasible solution among many feasible solutions of equal grid configuration for both square and rectangular *** analysis is also carried out between square and rectangular grids using the least square curve fitting technique as it results in only one unequal grid *** results are obtained by theMATLAB software *** of improvement in ground potential rise,step voltage,touch voltage,and grid resistancewith variation in compression ratios are plotted.
