In the article we have considered the basic advantages of the choice of parameters of static converters, as well as the basic classifications of static converters
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
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

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
