Abstract

Abstract The method, algorithms, modeling, calculations and analysis the 0.38 kV electric network operation with unbalancing power consumption are considered. It is noted that the 0.38 kV electric networks, being electric low observability networks, are largely characterized by low power quality, which is accompanied by additional losses. An electric network model with a distributed load is presented. The current and voltage asymmetry indicators calculating method is developed, and the specialized balancing device parameters are determined. Bas ed on the obtained expressions, using Matlab technologies, the calculating asymmetric modes program was developed. The studied indicators were calculated for the created electric network model with symmetric and asymmetric loads. The balancing device influence degree on the quality indicators stabilization and the electrical energy additional losses reduction is established.
