In the autonomous power supply systems there are
widely used frequency converters that are able to
simultaneously increase or decrease the frequency of
the current and voltage stabilizing power supply.
These positive properties of frequency converters can
improve the operational and technical characteristics
of the autonomous power supply system in the
complex. The article suggests a functional diagram of
a frequency converter performed on reversible
rectifiers. We have presented timing diagrams
illustrating the principle of its operation. The article
also deals with two functional scheme of direct
frequency converters executed on single-phase, threephase
transformer with a rotating magnetic field. The
principle of operation of these schemes has been also
discussed in the timing diagrams. The proposed
technical solutions for frequency converters contain a
smaller amount of power electronic devices that make
it possible, thereby reducing the level of
electromagnetic interference, increase the efficiency
and reliability of performance inverters. The
considered scheme of frequency converters, can
improve the technical characteristics of the
autonomous power supply systems in the complex. We
can significantly improve the performance of power
systems through the use of modular aggregating
principle of the basic functional units of an
autonomous system

The article discusses a promising direction, aimed at improving the operational and technical characteristics of the autonomous power supply systems, through the use of a part of their gas piston power plants, wind pow-er and solar photovoltaic installations
The article describes scopes and new technical decisions of static converters of the electric power with the improved operation-characteristics, executed with use of new element base and a modular principle of construction
This article discusses the basic analytical expressions for calculation the energy potential and cost-effectiveness of wind energy
Synchronous generators are the primary source of electrical power autonomous electrosupply systems, including backup systems. They are also used in a structure of rotating electricity converters and are widely used in renewable energy as part of wind power plants of small, mini and micro hydroelectric plants. Increasing the speed and the accuracy of the system of the voltage regulation of synchronous generators is possible due to the development of combined systems containing more stabilizers. The article illustrates the functional schemes of circuit voltage stabilizers and frequency synchronous generators (with electromagnetic excitation and permanent magnet excitation) and describes the features of their work, including two and three-aggregate rotating converters of electricity used in uninterruptible power supply systems. To improve the technical characteristics of the system of stabilization we have proposed functional solutions for stabilizers of synchronous generators made on the base of direct frequency converters and using a transformer with a rotating magnetic field. To improve the reliability of and to improve the operational characteristics of the autonomous independent sources of electricity we suggest creating the main functional blocks and the elements of the stabilization system in a modular way. The functional circuit solutions of voltage regulators of synchronous generators and the characteristics of their work considered in the article, are able to improve the efficiency of pre-design work in the development of new technical solutions for stabilizing the voltage and the frequency in synchronous generators of electrosupply autonomous systems
