“…As a result of a series of experiments with different test signals in the study (Kirkham and Riepnieks, 2020) and from the point of view of measurement theory, it was concluded that it is necessary to choose a single measurement method and revise the standard (IEEE std 1459(IEEE std -2010(IEEE std , 2010. Polish scientists (Olencki et al, 2020), whose work is devoted to the issue of electricity metering, emphasize the rationality of the fundamental frequency power allocation, "fundamental power" in the nonsinusoidal current system. Significant influence on the calibration problems of meters that keep records of active and reactive powers is emphasized.…”

Purposes The purpose of this paper is to identify on the instantaneous electrical power basis of a nonsinusoidal periodic current three-phase asymmetric system, active and reactive positive, negative and zero sequence powers, taking into account higher harmonics. The main power theories, including those embodied in the IEEE 1459 standard, do not allow to evaluate some of power components. Design/methodology/approach A well-known fact is that the three-phase AC system total power with the symmetry of currents and voltages is constant. It corresponds to the electrical energy transfer process in a DC system. In this case, the electrical energy transmission can be taken as high quality. It has been established that the components of active and reactive powers are because of the product of current and voltage of unidirectional sequences. The orthogonal components of the oscillating power are because of the product of the voltage and current components of different sequences, with the exception of the zero sequence. Findings For an unbalanced nonsinusoidal mode of a three-phase system, the components of instantaneous power were defined, corresponding to the active and reactive positive and negative and zero sequences powers with the selection of the fundamental and higher harmonics. The active and reactive powers of sequences were divided into two categories – consumed and generated. Originality/value It is proposed to use the ratio of “interfere” power RMS value to the total power RMS value to assess the instantaneous power distortion.

As shown in general terms by the statistics of emergency shutdowns and limit periods of operation of electric grid elements and electrical equipment, the main objective when connecting prospective industrial and residential complexes is to ensure uninterrupted power supply. To this end, new prospective and power lines for consumers need to be reconstructed or laid. This requires the development and implementation of automated calculation system with improved methodology for selecting cross sections of conductors of 10–35 kV power lines. This also needs to take into account a number of additional economic parameters, including the criterion of minimum discounted costs. This has resulted in new values of economic current density for each subject of the Russian Federation, corresponding to new eco-nomic conditions which differ significantly from those given in PUE. The study performed an analysis of the influence of economic current density on the territorial dispersion of electric power prices, discount rate, dynamics of load growth and prices for repair and maintenance. This confirms dependence on the economic situation in the country. The software product developed as a result enables recalculation of the power line for further reconstruction and mo-dernization. In addition, as mentioned above, values were calculated for all regions of Russia, taking into account highest load time. The use of the automated calculation system will reduce the time needed for calculation when determining the type of line, cross-section and voltage for further forecasting of newly connected facilities as well as existing ones, it will also enable a correct and justified choice with a minimum of initial information.
