PHOTOVOLTAIC PLANTS: PROSPECTS, ADVANTAGES, DISADVANTAGES AND THEIR CHARACTERISTICS
DescriptionAnalysis of scientific literature has shown a promising direction in energy saving and in increasing of efficiency of power supplies remote from external networks in Russia is the application of solar photovoltaic power plants. The level of solar radiation on the territory of Russia varies widely from 810 kWh/m2 per year in remote Northern areas to 1,400 kWh/m2 per year in southern areas. We have revealed their main advantages and disadvantages of solar photovoltaic power plants, as well as the purpose, basic features, features selection and operation of inverters and batteries. We have also given a generalized block diagram of three types of solar photovoltaic power plants: autonomous, standby, network. The peculiarities of their work have been presented. To improve the reliability of operation of solar power plants we need to design them according to the modular principle. Modular aggregation has to be applied for stand-alone inverters, where the input and output filters, power electronic circuit and system voltage regulation and protection represent the functional module elements. It is possible to increase significantly the reliability of autonomous inverters and solar PV systems in the complex, using one-phase and three-phase transformers with rotating magnetic field in their design. The advantages and the disadvantages, the peculiarities of the solar PV plants discussed in the article will allow to develop their structural and circuit designs with improved maintenance characteristics in the future

REQUIREMENTS AND CONSTRUCTIVE DIFFERENCES OF A STATIC CONVERTER
DescriptionIn this article technical requirements to static converters are examined. We can treat as the basic parameters: efficiency and quality of a target voltage. Weight-dimensional parameters, reliability, maintainability are basic operational parameters, as well as target capacity, size of an starting and target voltage belong to key parameters of static converters. As a rule designing of converters is a uniform constructive complex. As at designing, time of an operating time until first failure is taken into account, time of guaranteed work of the separate elements included in the static converter, are determined on the statistical data. Failure of separate elements of parts of converters are possible because of internal (time of guaranteed work) and external (short circuits, overloads) factors. In the article we have offered the ways of reduction of influence of external factors (for example, we used high-speed automatic switches or iterative static converters in which parts of a power circuit were included in parallel). Using universal static converters allows raising some parameters of efficiency simultaneously. In the article we have also considered a scheme of the iterative converter with variable structure which allows (depending on start and target conditions or requirements) forming an output capacity of the required level and quality without constructive change

SOLAR PHOTO-ELECTRIC STATIONS: PROSPECTS, FEATURES OF WORK AND CALCULATION OF ECONOMIC EFFICIENCY
DescriptionIn 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

SOLAR PHOTO-ELECTRIC STATIONS AS A BASIC ENERGY SOURCE
DescriptionNowadays, for maintenance of uninterrupted electro supply we found the most actual using sources of re-newed power; however, their application for electro supply of agricultural consumers is limited to a line of ecological and economic problems of the accumulators connected first of all with use. In the article we present one of the variants of the decision of the designated problems

Description
The article considers the main types of wind and solar electric installations, and provides a comparative analysis of the renewable energy potential of the Krasnodar region. Currently, humankind cannot live without electricity. Production and consumption of electricity is constantly increasing and the cost of it is constantly becoming more expensive. The cost of oil production (to get oil out of the ground) increases. The cost of electricity is going up because the cost of basic materials such as copper is at an unprecedented high. Such alternatives energy sources such as solar and wind are real solutions to these problems, moreover, the cost of "traditional" energy sources will only increase. To date, the most popular and invest renewable energy sources are the solar energy and the wind. The solar energy in the Krasnodar region is more profitable than wind, despite the fact that the production of solar installations is more expensive. But every year, the price of solar energy is being reduced and soon will be equal to the price of wind energy, and science and technology do not stand still, and considering the abundance of sunlight in the Krasnodar region, the solar installation will pay off much faster
