The problem of electricity losses management in distribution electric networks (DEN) operating in conditions of asymmetry of currents and voltages is reviewed. As it is known, the asymmetry factor leads to significant losses of active power and, as a result, decreases the efficiency and technical and economic indicators of the DEN. The purpose of the control is to minimize technical energy losses in the distribution network based on the creation of an automatic control system (ACS) for the process of balancing a three-phase network in the composition of automated meter reading and control system (AMRCS). The latter are currently being widely implemented to automate information processes in DEN. However, AMRCS does not include in its composition technologies designed to solve the problem under review. A method is proposed for constructing a digital ACS controller, the main function of which is to maintain phase currents at the network input at a given level in real time. The concept of the method is based on the idea of the desired redistribution of electricity flows between the phases of the distribution network by appropriate switching of single-phase consumers (customers) so that the minimum spread of phase currents from their specified level is ensured. To achieve the goal of control, criterion functions are constructed that determine the qualitative indicators of the functioning of the ACS. Algorithms for the functioning of the digital controller and the formation of control actions on the subject have been developed. The latter are a digital code containing data on the coordinates of electricity meters of consumers of a three-phase network to be switched to another phase.
