In order to simplify the modes analysis in power systems software tools for mathematical modeling of processes are used. There are many software products, but most of them are paid. For carrying out a laboratory work and obtain the results in certain sections of the thesis the authors of the article actively use the free software product "Elplek". But in a deeper study of the software product abilities we faced certain the task features of some parameters that are slightly differed from the generally accepted domestic methodology, which led to errors in the calculations in some versions of power schemes. The research aim is to study the peculiarities for setting the various elements parameters in the software product "Elplek" and to verify the adequacy of the existing models. At first the object of study was selected - a segment of the electrical network containing a small number of nodes - and a theoretical calculation of the short-circuit mode required parameters in this electrical network segment was carried out. Next an approach was proposed to set the elements parameters in the software product "Elplek" and based on this approach the simulation was carried out and as a result of which we obtained . Theoretical calculations showed that , i.e. the active part of the calculation results differ by 0.17 %, and reactive differ by 0.022%. This makes it possible to assert about the feasibility of using the proposed approach in the analysis of both normal and emergency modes of complex power supply schemes for consumers of certain power systems segments.
Key words: power system segment modeling, Elplek software product, element parameter setting, short circuit currents
