description: The given work is dedicated to researching automatic shutdowns of double chain overhead power line 110 kV âShepsi-Tuapseâ of Sochi electrical grid of public limited company âKubanenergoâ that accrues due to lightning overvoltages and application of measures to reduce their number.
This thesis aims to develop a system of lightning protection of the overhead power line by means of surge arresters and their optimal placement, which would allow to discontinue using a lightning protection cable.
The research set the following goals:
1.creation of a research power line model;
2.creation of a surge arrester model;
3.placement of the arrester model in the power line model in three differentconfigurations (at the top phase, at the top and the middle phase separately,at the top and the middle phase parallel to each other through an inductionelement);
4.calculating the amount of energy that flows through a protective electricalapparatus at various external impacts: a) the place of direct lighting strike (themiddle part of the span, the power line support); b) lighting current ampli-tude;
5.recalculation of the obtained data to determine the number of protective elec-trical apparatuses that break down per year and the probability of such inci-dents;
6.analysis of the results and elaboration of recommendations to decrease thenumber of power line automatic shutdowns.
Analysis has been conducted by means of mathematical modeling with EMTP software.
On the basis of the studies, it was decided to montage 2 surge arresters, con-nected parallel to each other through an induction element, without using wave conduct cable montage.
