The article shows that to improve the performance of autonomous systems we need new methods and principles of their design, associated with both the use of renewable sources and the application of new technical solutions of electromechanical generators and static stabilizers and inverters electric power settings. We have disclosed modern requirements for generators of electric power, as well as features of calculating the parameters of contactless electrical power generators: asynchronous generators capacitive excitation and asynchronous generators with permanent magnets. The article presents some analytical expressions for calculating the electrical losses and the efficiency of the generators, specific weight and power. It is shown, that expedient to designing contactless electrical power generators to carry out as part of the autonomous electricity supply systems, as it is sometimes advantageous to understate the main criteria of efficiency of generators, in order to improve, for example, weight and overall dimensions of static converters. The conclusion is made that in order to improve the efficiency of designing contactless electrical power generators in the early stages of designing it is necessary to carry out a preliminary assessment of the main criteria of efficiency of contactless electrical machines. We have also discussed analytical expressions, which might be used for preliminary evaluation of application features for various types of contactless generators in the stand-alone electricity supply systems taking into account the conditions of use
The article describes the main block diagrams of three
types of uninterruptible power supply: backup;
interactive; double conversion. The main functions
are: the function backup or emergency source of
electrical power; the function of protective devices
(from an overload currents and short-circuit);
improving the quality of the power supply voltage.
Alsoб we have disclosed the features of the advantages
and disadvantages of uninterruptible power supplies
three groups: Off-Line / Stand-By / back-up UPS
(passive - reserve); Line-Interactive (line interactive
type); On-Line. The article discloses new approaches
to structural and schematic-based uninterruptible
power supply, including at use of renewable energy, so
that the failure of one of the sources does not lead to
exit from the operation of the entire of power supply
system. As a rule, such systems are built on a modular
principle. It is shown that now for remote users from
external networks is advisable to apply a system
autonomous power supply, representing the totality of
sources and converters of electric power, ensuring
uninterrupted power supply to consumers. We have
presented a typical structure of autonomous systems
and given an option of the block diagram of the system
and are given explanations and principles of its work.
Significantly improves performance reliability of
autonomous systems using the modularity of its main
functional units. In addition, to increase the efficiency
of the system can be through the use in the
construction of transformers with static converters
rotating magnetic field. To improve the weight, which
is important for the transport systems, it is necessary to
use links with the intermediate high-frequency electric
power conversion in static converters
The article reveals main reasons for developing
tendencies to the using of new types of energy, which
are limited supply of traditional fuels and
environmental problems associated with its
processing. It is shown that new forms of energy
plays an important role in the energy supply of many
countries of the world, and in the future they can
become the main sources of energy to meet the
growing needs of the global economy. We reveal
main reasons of the increasing interest in renewable
energy, and we show the obvious prospects of their
use, due to two factors. First, according to experts,
the global reserves of traditional fuels are limited, and
secondly, this was evidenced by the investments of
leading countries in this promising industry. The
article lists reasons for the need for the use of
renewable energy sources in Russia. Increased
consumption of natural resources has become a real
threat to the security of the life of human society. The
basis of solving modern social and environmental
problems is a transition to a regulated process of safe
use of natural energy potential to meet the vital needs
of people not only in the coming decades, but in the
long run. It is concluded, that the determining
condition for the development of the human
civilization at present and in the future would be the
level of natural resources which ensures the needs of
the population without making harm to the
environment
