FREQUENCY CONVERTERS WITH IMPROVED PERFORMANCE
Description
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

VOLTAGE REGULATORS OF SYNCHRONOUS GENERATORS
Description
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
