In article the basic lacks and characteristics of solar power stations, features of their design, work and prospect are considered
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
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
It is known, that today, the one of the promising
areas to effectively address issues of energy saving
is applying renewable energy sources. Despite the
fact that the current solar PV stations have the main
drawback associated with the high cost, the prospects
of their application in autonomous systems
of electrosupply are evident when they are used in
combined (hybrid) systems. In such systems, other
types of renewable and traditional sources of electricity,
which, in addition, produce heat, might be
used as well. We have disclosed the prospects of
the solar industry; also, for solar energy assessment
we examined analytical expressions allowing defining
the energy derived from solar radiation for specific
surfaces. The calculations start with obtaining
statistical data obtained at meteorological stations
which keeps records of the intensity of the total
(direct plus diffuse) radiation on a horizontal surface,
and the intensity of direct solar radiation. The
article presents features of the calculation taking
into account the climatic and territorial conditions,
on the example of the Krasnodar region. Considered
calculation procedure is the first stage of designing
solar power plants. Further, we determine
the total capacity of electricity consumers, as well
as the quality requirements for electricity, including
continuity of supply, and then we get to the construction
of the block diagram of the electricity
supply. In this scheme, we must provide primary
and backup power sources. We select the main
equipment of solar power plant (solar panels, inverters
and storage batteries)

Further, the total capacity is determined by electricity consumers, as well as the quality requirements of electricity, including continuity of supply, embarking to the construction of the block diagram electricity supply.

Widespread in autonomous systems, including
uninterrupted power supply systems, there are power
static (electronic) convertors: rectifiers and inverters,
used to match the parameters of the electric power
source and the load; they also have a function of voltage
stabilizers. Important question is the calculation of key
performance criteria at the design stage: power losses,
efficiency, reliability, weight and size (for electrical
transport systems). The article discusses the
methodology of the simplified calculation of the basic
criteria of efficiency of inverters and rectifiers. There
are schematic electrical diagrams of power rectifiers
and inverters, and the basic analytical expression for a
simplified calculation of the basic criteria of efficiency
of the converters, including their output filters. Each
year, we improve the technical characteristics of the
probes using new element base, allowing reducing the
level of electromagnetic interference generated by
power electronic devices. We have also shown
perspective directions of the development of power
converter technology by using one-phase and threephase
transformers with rotating magnetic field in their
creation (therefore we increase reliability of operation
and efficiency). A promising direction is the
construction of converters and autonomous systems in a
modular complex, where (in addition to increased
system reliability) we simplify its operation, including
service
