 network is based on intelligent technologies of network-centric
 control of heterogeneous objects. The introduction of unmanned
 aerial vehicles for monitoring of three-phase network increases
 the efficiency of management. Methodology. The case of decomposition of the instantaneous capacities of the fixed and
 variable components for 3-wire system. The features of power
 balance for the different modes of its functioning. It should be
 noted that symmetric sinusoidal mode is balanced and good, but
 really unbalanced, if the standard reactive power is not zero. To
 solve the problem of compensation is sufficient knowledge of the
 total value of the inactive components of full power (value of the
 inactive power) without detail. The creation of a methodology of
 measurement and assessment will require knowledge of the
 magnitudes of each inactive component separately, which leads
 to the development of a unified approach to the measurement
 and compensation of inactive components of full power and the
 development of a generalized theory of power. Results. Procedure for the compensation of the current of zero sequence excludes from circuit the source, as the active component of instantaneous power of zero sequence, and a vector due to a
 current of zero sequence. This procedure is performed without
 time delay as it does not require integration. Only a 3–wire
 system with symmetrical voltage eliminates pulsations and
 symmetrization of the equivalent conductances of the phases of
 the task. Under asymmetric voltage, the power is different, its
 analysis requires the creation of a vector mathematical model of
 the energy processes of asymmetrical modes of 3–phase systems. Originality. The proposed method extends the basis of the
 vector method for any zero sequence voltages and shows that
 the various theories of instantaneous power three wired scheme
 due to the choice of a basis in a two-dimensional subspace.
 Practical value. The algorithm and software implementation for
 the decomposition of the zero sequence current, which allocated
 the procedure of obtaining null-balanced vectors of phase and
 interfacial voltage, calculation of active and inactive instantaneous power is zero balanced mode. The simulation results
 obtained in the software package Matlab by the method of visual programming in Simulink.
