The asymmetrical distribution electric network is considered in the conditions of functioning of the automated meter reading and control system (AMRCS). The problem of identification of its mathematical model in a complex form which comes down to definition of phase shifts of the variables (currents, tension) defining an electric status of three-phase network is formulated. The method of its solution based on the mathematical ratios describing functional communications between state variables and use of algorithms of parameter optimization is offered. The realization of identification procedure of model of a distribution network is enabled with direct use of the basic data obtained on communication channels from subscriber's meters of the electric power. The method can be used for a solution of a number of functional tasks as a part of the AMRCS oriented for diagnostics of statuses of a trunk line and energy losses in a distribution network.
