Software For Improved Online Teaching Of Power System Analysis For Undergraduates

Abstract

Soil layer resistivity modelling is a vital component of grounding system design. Grounding system for facility, equipment, power station and general system protection purposes must be designed to be able to handle the anticipated level of fault current. To achieve this; the earth rods, mats and any other equivalent alternatives deployed must be adequately sized in terms of the physical dimensions and the number of such rods required in order to achieve the desired low, overall grounding system resistance. The resistance to earth of a grounding system is a function of the resistivity of the soil in concern, and to ensure appropriate design, the resistivity profile of the soil must be determined via appropriate soil modelling. This paper presents a Monte Carlo simulation approach to two layer soil modelling using the square error as an optimization function. The result of the simulation shows an improvement in model accuracy, and it also conforms significantly with the results of published works that applied genetic algorithm.

Investigation of the Impact of Distributed Generation on Power System Protection

“…From this, it can be seen that R/X Ratio is 1.311688, which is high compare to the transmission network, which is always less than 1. Also the conventional load flow analysis will not converge for the distribution network because of the high R/X Ratio [19]. Hence NEPLAN software is used to carry out the load flow analysis of this study.…”
