The proposed complex models of adjustable electrical drives with high-phase order induction motors give a possibility to carry out the grounded choice of the drive's acceptable variant. Besides, they can be used as design models at the development of adjustable high-phase order induction motors. Practical value. The investigated change of vibroacoustic indicators at static and dynamical modes has been determined decrease of these indicators in the drives with number of phase exceeding 3.

Using the new energoeffektivnoe electrical equipment will not only significantly reduce power losses and operational costs, but also improve the reliability of power supply systems.

The application of a reactive power on bus leads DPP is an economically expedient action which allows solving part of local electric energy systems problems and having a payback expenses period about a year.

This article presents the structure and dynamic model of a dynamoelectric converter with frequency stabilizer; transferred synthesis from analog and digital regulators of automatic high-frequency stabilization system, allowing high-precision and acceptable dynamic characteristics to provide automatic power supply devices. A comparative analysis of the results obtained from the use of MatLab.

The statistical analysis of technical condition of electric driving gas-distributing units on the main gas pipelines of Russia is submitted. Innovative ways of increase in energy efficiency of operation of the main gas pipelines due to use of new technologies and algorithms of the combined systems of automatic control of frequency and adjustable electric drives of modern gas-distributing units are considered. Adaptive structures and regression algorithms with optimization of the choice of systems of power supply of technologically connected electric driving superchargers at compressor stations are offered.

The causes of damage to the elements overhead lines kV voltage. The basic measures to improve the operational reliability of overhead lines of 110 kV, which must be provided at the stage of design and operation.

Provides the theoretical principles of the methods of calculation of amplitude and angle errors of voltage transformers (VT) when working with nonlinear load. It is shown that increases the full power of nonlinear loads, but the amplitude error of VT does not increase. It is determined only by the output load at the fundamental frequency. In this case, the angular error is determined by the level and composition of the harmonics and may differ from the angular error at the first harmonic.

Formed by professionals and Industrialists graphic descriptions use network dictionaries, libraries of graphic primitives and images are the most effective means of preparing personnel for electrical safety of production and subsequent reliable control of their knowledge, which can be considered as one of the solutions to create elektrobezopasnosti production.
