The work is done in scientific and practical directions
for minimization of power losses in transmission of
electricity to local distribution networks between the
actors of the energy (producers and consumers) of
energy-saving technologies focused on technological
activities such as modernization and reconstruction of
networks. Quite often in various circuits of power
systems, it is advisable to transfer energy and its power
through intermediate (transit) nodes. Structural
changes in the electricity sector, at present, are mainly
associated with the introduction of market relations
between the subjects of energy exchange; therefore, in
this work special attention is paid to the problem of
calculating the power losses, as it is nonlinearly
dependent on the power at the nodes and branches of a
network. It should be noted that the nodes in problems
transit capacity could be both sources and consumers.
The latter necessitated the need for search of possible
ways to reduce transportation losses of energy due to
both the improvement and optimization of distribution
networks and through the use of intermediate transit
nodes. It follows that the transportation problem in this formulation is more General and expands the
possibilities of optimization of power losses for the
local subsystems of the energy clusters. The work is
composed of the transport matrix for solving problems
transit capacity, where the algorithm taking into
account the distinctive features of which consist in the
use of continuous numbering of sources and
consumers in the matrix, and any node can be a transit
country. The transit capacity ii-th node Zii=0, and the
dimension of the matrix in contrast to the previously
considered tasks has (n+m) (n+m) and it remains
square as all the transport problems of linear
programming. Transit variables Xii are included in the
solution of the problem with a minus sign, and all
transit variables are considered basic. From the above
example in the work of a number of branches of a
network is minimal, which significantly reduces the
cost of building and maintaining the network, and the
solver minimizes the power loss between the subjects
of energy exchange and, as a result to savings from the
standpoint of cost of construction of the network and
the management of overflows of energy in it

In this article, problems of multiparameter fuzzy systemsâ€™ state forecasting are reviewed. The algorithm of selection of the equipment on significant parameters of the engine is given

The work is done in a scientific and practical ways to
minimize power losses in the transmission of
electricity in the interregional distribution networks
from the sources to the consumer by the use of tasks,
ensuring the gradual improvement in the support
program, not only from the standpoint of the efficiency
of reduction of transported power loss, but also due to
a significant decrease the complexity of the
calculations. The resulting shortage of electricity
power associated with its transfer to the electricity
networks, has demanded the need to find possible
ways of reducing the value of electricity losses during
transportation, both by improving and by optimizing
distribution net-works schemes. Consolidation into a
single set of electrical equipment, called the power
cluster is connected to the sources of power and energy
consumption, make better use of new principles of
control technology and the transmission of electricity,
on the basis of an automated monitoring system,
ensuring the redistribution of energy flows and
optimize them. The process of electric power
transmission and reduction in electric power loss can be considered on the basis of linear programming
problems, and their modification in the form of a
transportation problem, and as a result, the transport
matrix. On this basis, manipulating the data table, we
can find acceptable solutions, well and then determine
the best of them. As examples, this work has carried
out the study on the basis of the three methods -
"northwest corner", the method of minimum unit cost
of electricity transport, as well as the method of the
potential. The use of these three methods yielded
acceptable solutions, to identify the most appropriate
for the number of steps carried out at the decision, to
reveal that the winner is the potential cost method

In this article we study connection between frequency
characteristics of oil filter and lubricant system condition of internal combustion engine. Method is suggested, it allows to trace changes of technical condition of oil filter, engine oil, engine and to estimate a residual resource of working capacity up to maintenance

In this article we study the connection between pollution extent of oil filter, hydraulic resistance and medium value of filter capacity for a certain period. We established following: if the maximum productivity of the filter is decreased, that maintenance of internal combustion engine is necessary. This value is connected with maintenance periodicity

In order to improve the security of information transfer we have offered one of the possible approaches to modeling process control computer networks with elements of intelligent decision support. We proceed from the graph model of network nodes which are network devices with software control agents, and arcs are logical channels of information exchange between the equipment computer systems. We built an addressless sensing technology which ensures the completeness of monitoring of all network equipment. To classify the computer networks state we provided a method for calculating the values of reliability. Development of signal mismatch triggers the control cycle as a result of which the adjustment of the state of network equipment. For existing tools we proposed adding network control expert system consists of a knowledge base, inference mechanism and means of description and fill in the knowledge base

The article proposes a method of research, evaluation and selection of priority parameters for monitoring and prediction of a technical condition of engines using the method of factor analysis

The article discusses the two ways to scaling storage chronological data systems. The formulas for calculating the optimal duration of the period (to split the data by period) and the maximum allowable rate for guaranteed preservation in the system are presented

The work is scientific and practical in nature, same as
the discussed process of optimization of power losses
in power networks based on the use of the
transportation problem, namely the rules of the
minimum element of the transport matrix, which is a
valid solution. The mechanism of the improvement of
the obtained feasible solutions to the tasks focuses on
using the potential method, assigning each row and
column of the matrix their corresponding potential.
Using a basic variable and manipulating the elements
of the transport matrix according to a specific
algorithm, we implement the construction of a new
support plan. Based on the plan and its acyclic, we
build two cycles and determine the values of the
estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes
it easy to program all computational operations and
quickly obtain the result of the optimization of power
losses in the design of the electricity network, thereby
reducing the economic and technological costs. As a
result of joint use of transportation problems and
potential method, we could find the optimal solution
based on improved solutions more efficiently, and a
scheme of optimal electric network. As consumers, in
practice, there may be urban and agricultural,
industrial enterprises, regional and district
subordination, including industrial, agricultural and
individual customers

In the article we have allocated a number of poorly formalized functional tasks that significantly affect the efficiency of the operation of distributed information-analytical systems. The scheme has been developed for the iterative process, which in addition to the automation of the delivery process and the exchange of information between information systems based on grid integration, also includes funds for applied modeling situations on the basis of available information, developing alternatives, multi-criteria decision problems using techniques scenarios and peer review. Obtained during the evaluation of the effectiveness results allow us to control and manage the operation of distributed information-analytical systems with specific problems, as well as to conduct simulations and analytical processing
of the results
