New way in design of a power station earthing system

This article discusses the design of a power station earthing system using two methods that are compared to each other. The design was based on the software method using CYMGRID and the mathematical method based on IEEE 80-2000. The process in both methods is aimed at creating a grounding model, determining the overall resistance, overloading the cross-sections of the earthing switches and adhering to the limit values for the touch and step potential. The work compares these analyses and evaluates the differences in design and possible shortcomings, such as the possibility of over-dimensioning or underestimating the grounding system.
