Abstrakty

EN

Operation modes of 0.4/0.23 kV power supply systems are modelled using Monte Carlo method by means of Electronics Workbench software and statistical processing of simulation results and testing of the Pearson distribution law hypothesis using Mathcad are carried out. An analysis of existing power supply systems has been conducted and an alternative, economically feasible version of a power supply system is proposed, where consumers are supplied from low power transformers mounted on supports.

Streszczenie. Tryby pracy systemów zasilania 0,4/0,23 kV są modelowane stosując metodę Monte Carlo za pomocą programu Electronics Workbench, i przeprowadzane jest statystyczne przetwarzanie wyników symulacji i testowanie hipotezy prawa dystrybucji Pearsona za pomocą programu Mathcad. Przeprowadzono analizę istniejących systemów zasilania i zaproponowano alternatywną, ekonomiczną wersję systemu energetycznego, w którym odbiorcy są zasilani z transformatorów małej mocy zamontowanych na wspornikach.
