To the problem of localization of unauthorized selection of the electric power in distributive networks as a part of ASCAE
T.T. OMOROV

Increasing the efficiency and technical and economic indices of automated control systems and the accounting of the electric power (ASCAE) causes need of development for their composition of the functional subsystems intended for diagnostics of statuses and optimization of operation modes of the distributive electrical networks (DEN). In article the problem of identification and localization of unauthorized selection of the electric power on the asymmetrical three-phase network which existence causes a deviation of its status from the desirable (rated) that leads to the considerable technical and commercial losses of energy is considered. The method of its decision based on identifications of parameters and state variables of a network in real time is offered. As a last used current, voltage and
resistance, characterizing the electrical state of the three-phase network. The received results are oriented for creation of a subsystem of diagnostics of statuses of RES as a part of ASCAE.
Keywords: three-phase network, asymmetrical mode, unauthorized selection of the electric power, method of identification and localization.
