Investigation and approximation of gpr in multilayered soil structure
(Institute of Advanced Scientific Research, Inc. dheep.infotel@gmail.com, 2019) Senthilkumar, R.T.; Selvakumar, K.
The current investigation aims at the analysis of the structure of the soil at the substation site which is a prime pre-requisite in designing the substation. The key specifications to be estimated with obtained site details are number of layers, and the electrical specifications like resistivity and thickness of every layer. The equivalent model for the Earth structure based on the measured resistivity is designed using the RESAP module in CDEGS software. The performance of the concealed conductors under the ground surface in frequency domain is calculated using the MALZ module and HIFREQ module is used to resolve the Ground Potential Rise (GPR) when injecting fault current in the grid. The Present article also discusses about the consequences of the GPR and alternative ways to improvise it. © 2019, Institute of Advanced Scientific Research, Inc.. All rights reserved.
Optimization of multilayer earth structure by using steepest descent method and estimation of transient ground potential rise in substation
(2018) Senthilkumar, R.T.; Selvakumar, K.; Nagaraian, K.
The purpose of this paper is to analyse the impact of ground potential rise in the design of substation. Investigation of soil structure in the substation site is the pre-requirement to design the substation. Number of layers, resistivity of each layer and thickness are the parameters to be estimated with the measured site data. By using RESAP module of CDEGS software optimizing the parameters of soil structure. Ground potential rise of substation to be computed when the fault current is injected in to the grounding grid in power frequency using MALZ module and HIFREQ module of CDEGS. Further discussed about the safest ground potential rise and the ways to improve the safest GPR. � 2018 IEEE.

Optimization of soil parameters in multiple layers of ground structure
(2018) Senthilkumar, R.T.
This paper proposes an optimization methodology to estimate the parameters of multilayer earth structure by using the hybrid genetic algorithm and particle swarm optimization. By using four wire Wenner method on the ground is to acquire the experimental apparent resistivity curve. With the measured experimental apparent resistivity, can compute the theoretical apparent resistivity curve and estimate the soil parameters such as a number of layers, thickness of each layer (Nth layer thickness is infinity) and its resistivity. The representation of unknown soil is determined by comparing the closeness of experimental apparent resistivity curve with the theoretical optimized apparent resistivity. � 2017 IEEE.
