In the article we have presented the models of refusals and restoration of the power transformer, the model of refusals and restoration of the automatic switch, the model of refusals and restoration of an air-line of electricity transmissions; we have also made conclusions for the presented models and offers for introduction in manufacture
This article presents the issues related to the distribu-tion of ozone in detoxification of feed grains and drawing up the balance of ozone consumption. The article also contains theoretical dependences obtained experimentally
The article considers prerequisites for the development
of complex software and tools for data analysis,
modeling, forecasting and management decision
making in the management of IT-projects. System of
decision support can facilitate the work of heads of
enterprises and increase its efficiency. They
significantly accelerate the solution of problems in
business. In the organization, there is a software
complex, which suggests that the transmission of
information about incoming orders and deadlines for
every Department and information on the
implementation of the orders of the head is performed
via the software package. Using software system, the
client leaves a request for the execution of services.
The Manager sends a request to the appropriate
Department. Units, in turn, convey information about
the status of the application via the software package.
The software package provides fast remote bilateral
communication in electronic form between the client
and Manager and between Manager and the
departments. In a company, the head and head of
sector perform the coordination of work in
implementation of IT projects. However, there are a
number of human factors that make people cannot
keep track of the timely execution of all requests from
subordinates
The article shows the main advantages and disadvantages of renewable energy sources. It is shown, that in general, the use of renewable energy in the world has acquired real momentum and stable growth trend. An interesting fact is that the greatest application was currently the most mutable and unstable form of energy - wind. The total global installed capacity of large wind turbines, according to various estimates, is approximately 20 GW. This is because the specific investment in wind power is lower than with most other forms of renewable energy. The article presents features of the design and operation of modern wind power stations. It is shown that when choosing wind power plants and stations we must take into account the following main parameters and factors: the average value of amount of electricity consumed by power consumers on a monthly basis; power generator; uptime in the absence wind or when weak wind. The study shows block-circuit solutions of different options of energy systems made using wind power plants. We have also disclosed prospects of development wind energy and considered the advantages and the features of the choice of the main functional units of wind power stations which will increase the effectiveness of predesign work on the creation of high-performance systems of electrosupply with combined power supply systems based on renewable energy sources
The article discusses the features of design and
operation in the different modes of functioning of
autonomous hybrid power plants based on renewable
and traditional energy sources. We have given a
structural scheme of such a plant. It is shown that the
algorithm of the system in the autumn-winter period
should be adjusted according to the monthly
monitoring; and standby generator of independent
source can be run at a deeper discharge of batteries. It
is known that the most expensive and the weakest link
in the solar PV plants is rechargeable battery. In
addition, the larger the number they have in the
system, the more complicated the fulfillment of all
conditions of proper operation is. We have proposed
to extend the lifetime of batteries through the use of
passive balancing, which allows to increase the
reliability of operation and reduce the cost. It is
shown that a real possibility of improving the
technical and economic performance of autonomous
hybrid power plants is their execution on the basis of
solar photovoltaic power plants. We have also
discussed the features of construction and operation
of hybrid power plants, which will increase the
efficiency of preliminary works on development of
high-performance structural circuit design of the
stations
In the article we have shown the calculation of optimal parameters of stabilization of pressure of steam in the boiler with changing the fuel supply
The article presents a brand new approach to the issue of automation of a workflow of the felling head to retain the truncated tree in an upright position when it is carried out of the woods. The model of holding tree upright and a block diagram of the position control of the felling head have been presented
The article presents the results of research, design development to automate the process of planting of seedlings and saplings with open and closed root system, in order to increase the operating speed, performance and level of mechanization, reducing manual labor and increase its security
The opportunity of modernization of industrial equipment for manufacturing of wood biofuel is shown. The article is devoted to system engineering of automatic control of equipment. Researches have been directed on increasing of technical and economic production efficiency of biofuel. The economy of the electric power for pressing makes 30-35 %. In aggregate, all the advantages provide sufficient increase of general technical and economic efficiency of the process
Techniques of value analysis and "Direct-costing" are
well-known and popular. The ideas and principles of
value analysis and the method of "Direct costing" are
very similar, if not identical. On the one hand, these
ideas are very reasonable, well grounded theoretically
and proved its effectiveness in practice. On the other
hand, the wide use of these methods is hampered by
the difficulty of obtaining large amounts of detailed
technological and financial-economic information, as
well as the need for careful research by competent
professionals, well-versed in substantive subject area.
This is the contradiction between the desire to apply
the methods of the value analysis and "Direct costing"
and difficulty to perform it in practice. This
contradiction constitutes a real problem and may often
be discouraging and frustrating. In this work, we
propose a simple and effective solution to this
problem, theoretically well-informed with all the
necessary methodological and software tools and
widely and successfully tested in practice. The
proposed solution is based on two simple ideas: 1)
instead of collecting and holding a meaningful large
amount of technological and financial-economic
information we might apply approaches, pleasant
management theory; 2) to create systems for
automated control of natural and financial-economic
efficiency of expenses we might use the automated
system-cognitive analysis and its software tool – an
intellectual system called "Eidos". In the name of the
specialty 08.00.05 – Economics and national economy management, there are such words: "management of
enterprises, branches, complexes, innovation." The use
of the term "Management" implies that there is a
model that reflects the influence of factors on the
object of control, and there is the management system
making decisions based on this model. However, as a
rule, the dissertations in this field have nothing of this,
except only financial and economic calculations. The
article proposes an approach based on the control
theory, removing this disadvantage
