Abstract The article investigates the accuracy of spatio-temporal modeling of main electrical networks based on open data published in schemes and programs for the development of regions.

Failure to take into account the segmentation of the network leads to errors in the attribution of temporal data, which in turn can lead to errors in planning the d

Abstract:

Electricity is an indispensable element of our daily life. When electricity is used inefficiently, technical and non-technical losses occur at the stages from power plants where energy is produced to the point of consumption. Reduction of these losses is defined as the main goal for more efficient use of existing energy systems. Since the increase in electricity tariffs due to inflation is happening all over the world, it creates conditions for the illegal consumption (theft) of electricity without accounting. For this reason, reducing the illegal consumption of electricity and compensating th

Abstract:

When we say asymmetry in electric networks, it means that the distribution of voltage and current on phases is not equal. One of the main reasons for this is due to the incorrect distribution of single-phase consumers in 0.4 kV supply networks by phases according to the load. In all cases, asymmetry causes uneven heating, lighting and mechanical torques in the windings and other elements of 3-phase electrical equipment. This, in turn, lowers the quality indicator of electrical equipment, and also leads to a shortening of their service life and, as a result, an increase in the rate of depreciat

Abstract:

A structural vibration control concept, using piezoelectric materials shunted with real-time adaptable electrical networks, has been investigated. The variable resistance and inductance in an external RL circuit are used as control inputs. An energy-based parametric control scheme is created to reduce the total system energy (the main structure mechanical energy plus the electrical and mechanical energies of the piezoelectric material and electrical circuit) while minimizing the energy flowing into the main structure. Stability of the closed-loop system is proved. The performance of the contro

Abstract:

Currently, there are several approaches for dealing with uncertain (inaccurate) data. The main ones are methods of probabilistic analysis, fuzzy set theory and interval analysis. In this paper, we consider the problem of calculating the parameters of steady-state modes of electric power systems with interval uncertainty of the initial data. The main reasons and the relevance of the use of interval methods for calculating the parameters of steady-state modes of networks of electrical systems are described. First, an interval calculation model is formulated, and then some interval iterative meth

Abstract:

One of the trends in the development of marine technology is the constant increase in the degree of electrification of ships. This process is accompanied by an increase in the danger of ship electrical networks, determined primarily by the operation of electrical installations with single-phase insulation damage. The consequences of this mode largely depend on the phase capacity of the electrical network. Moreover, the influence of phase capacitance on the danger of single-phase short circuits is determined not only by its size, but also by the degree of asymmetry. It is proved that it is prec
