Σκοπός αυτής της εργασίας είναι η εξομοίωση ενός πλέγματος γείωσης υποσταθμού μέσης τάσης και η μελέτη της μεταβατικής συμπεριφοράς του. / Grounding, is the connection of metal elements of an installation with
the ground, in order that the potential of this, is evened with the
potential of the ground. Aim of a grounding system is to provide a
street of low resistance in currents from lightning or faults to the
ground and to decrease the probabilities of growth of dangerous
incremental voltages or voltages of contact, determining a potential of
report.
The grounding systems are very important and for this reason have
been studied their behavior from a lot of researchers and have been
proposed various models of simulation. The more important piece than
the study of a grounding system is the transient response, because
there are presented the most dangerous phenomena and the voltages
which appear present largest values as well as more abrupt curves.
Aim of this work is to study and simulate the earthing grid of a
substation.
Θere are presented the results of the simulation of an earthing grid in
order for the thunder electricity to be inserted to the node where the
“tower" of 150 kV is being earthed and in order for the shift circuit to
be inserted to the node where the thansformer of the substation is
being earthed.
