CLASSIFICATION OF INDEPENDENT SOURCES OF ELECTRIC POWER
Description
In the article the description of the basic kinds of sources of the electric power, their merits and de-merits is resulted. Nowadays independent sources of the electric power on static converters are the most universal. In spite of the fact that electronic devices are capable to provide reliable enough electrosupply with consumers of various capacities and character of loading, however their bad fitness to high - dynamic loadings still is. Therefore elec-tromachine converters remain the basic source of the electric power, as the steadiest to overloads. So even in transport independent sources, for which weight-dimensions parameters are most critical, electromachine converters are used. In the article typical circuits of electromachine converters with synchronous and asynchronous generators, their advantages and lacks in relation to static converters are resulted. And as methods of increase of their efficiency, for example work on the part frequency, are resulted. For the sources executed on static converters, use of circuits with an intermediate link of the part frequency is most perspective, which, in its turn, allows to lower weight-dimensions parameters. As a rule, static converters have bad quality of a target voltage, therefore for increase of its quality use various target electric filters. Controlled filters whit electronic elements in their structure have the greatest efficiency

CLASSIFICATION AND ESTIMATION OF THE EFFICIENCY OF SYSTEMS FOR UNINTERRUPTED ELECTROSUPPLY
Description
In the article we present generalized block diagrams of stationary and transport systems of uninterrupted electrosupply, as well as their maintenance and the basic operating modes providing uninterrupted electrosupply of crucial consumers. Classification of systems of uninterrupted electrosupply is resulted. The basic classification attributes of systems of uninterrupted electrosupply are their assignment for stationary or transport consumers of the electric power, types of used basic, reserve and emergency sources and converters of the electric power. Besides systems of uninterrupted electrosupply can be classified under circuits of connection to consumers of the electric power, their division on a sort of a current (constant, variable, high-frequency), breaks in electrosupply, to type of the switching equipment and so on. For the estimation of the efficiency of systems of uninterrupted electrosupply it is offered to use the following criteria of efficiency: Power and weight-dimension parameters, parameters of reliability, quality of the electric power and cost. Analytical expressions for calculation of parameters of the estimation of efficiency of systems of uninterrupted electrosupply are resulted. The classification of systems of uninterrupted electrosupply suggested in article and modes of their work, and also the basic criteria of an estimation of efficiency will allow raising efficiency of pre-design works on creation of systems with improved customer characteristics with use of modern element base

SOLAR PHOTO-ELECTRIC STATIONS: PROSPECTS, FEATURES OF WORK AND CALCULATION OF ECONOMIC EFFICIENCY
Description
In the article, the general concepts and the maintenance of total, technical and economic resource of solar power are revealed. The advantages of solar power in comparison with other kinds of energy are resulted. We have shown, that currently the method of direct photoelectric transformation is one of priority directions of reception of solar electric power in the world. It is because it provides the maximal ecological cleanliness of transformation, an opportunity of reception of energy practically in any area, significant service life and small expenses for service. The structure and features of work of solar photo-electric installations were listed as well. The schemes of using photo cells and their voltage and amperes characteristics, lacks of solar photo-electric stations are resulted, basic of which are: high cost of photo-electric converters and presence of accumulators, and we have also offered recommendations on their effective use. The basic analytical expressions for definition of economic efficiency of solar photo-electric stations are resulted. The considered features of the work, the basic characteristics and the parameters of solar photo-electric stations which will allow to increase the efficiency of predesign works on development of the combined (hybrid) stations, generating electric and thermal energy, received from solar radiation
