Sažetak
The paper presents a part of the problem
in a prepared doctoral dissertation entitled
“An electromagnetic model for computation
of fault current distribution”. The choice of electromagnetic models, unlike all previously
developed analytical and numerical models
of famous authors, is the need to introduce
a computation the complete electromagnetic
coupling between all components, which includes
inductive, capacitive and conductive coupling.
Developed electromagnetic model is based on
a hybrid electromagnetic model (a combination of
the electromagnetic model and the transmission
lines model), based on the application of the finite
element technique and the numerical model,
which is based on the method of potential nodes.
In power systems, it is necessary to take
into computation a multitude of factors such as
grounding electrodes considered substations,
other substations with transformers, metal poles
and their grounding electrodes with associated
power lines and earth wires, cable lines with their
screens and bare conductors passed above them
and all other conductive parts. The engineering
modeling for the purposes specified uses a
multitude of mathematical tools, methods and
knowledge base indicating the universality of
application. In this part is selected modeling of
grounding metal plate.
