Earth Grid Design for 400KV Neiuwehoop Substation Using CDEGS Platform

2020 IEEE PES/IAS PowerAfrica, 2020
The earth grid design for substations is pivotal for substation design, particularly in high resistivity soil where resistance on the lowest layer is greater than the upper gradation soil. In this paper, a 400kV Neiuwehoop substation earth grid design is presented using Current Distribution Electromagnetic Field Grounding Soil Structure Analysis ...

The Research of CDEGS in Defect Diagnosis for Grounding Grid

Applied Mechanics and Materials, 2014
The paper briefly introduces the function and characteristics of the ground simulation software CDEGS, and computes the grounding grid model by using the MALZ module. The grounding grid GPR (Ground Potential Rise) and the percentage of reference power bus GPR are analyzed after the exciting current source injected into the grounding grid, and compared ...

Comparative analysis of the effects of different resistance reduction measures based on CDEGS calculations

2021 6th Asia Conference on Power and Electrical Engineering (ACPEE), 2021
Based on the actual measured soil resistivity in a substation, this paper uses CDEGS to calculate and analyze the effects of deep well grounding, oblique well grounding, and small well grounding on improving the grounding performance of the grounding grid.

Simulation of grounding networks in the SES CDEGS software

2015 Selected Problems of Electrical Engineering and Electronics (WZEE), 2015
The article presents a new concept in the area of mathematical modeling of grounding networks. The idea is to combine a few arbitrary homogeneities (finite volumes of prismatic shape), defined in the MALT module of SES CDEGS software by its developers, to build the polyhedron much more useful in grounding system simulations (finite length cylinder ...

Study on Dynamic Characteristics of Metro Stray Current Based on CDEGS

2018
In this paper, a stray current dynamic distribution model was established by Current Distribution, Electromagnetic Field, Grounding and Soil Structure Analysis (CDEGS) software. The rectangle cut-and-cover model is based on a practical construction in Shijiazhuang Metro Line 3.
