TECHNICAL SOLUTIONS OF AN ENERGY SUPPLYING COMPLEX OF APIARY BASED ON A SOLAR PLANT
DescriptionWe have presented technical solutions of an energy supplying complex of apiary based on a solar plant, which ensure its functioning in the winter. Various aspects of the influence of the snow cover on the functioning of the complex are considered in the article. The favorable effect of the snow cover includes increasing the diffuse insolation, improving the thermal insulation of the building for placement of bees, which protects bee families from fluctuating external temperature. The negative effect of the snow cover includes adherence of snow to the receiving surfaces of solar energy converters, which can lead to decreasing the efficiency of using of photovoltaic modules and solar collectors. Both active and passive methods of combating snow sticking are suggested in article. Passive methods include installation of solar energy converters at an angle close to 90°, as well as their placement on the windward side. The simulation of the functioning of the complex based on a solar plant was conducted for climatic conditions of the Republic of Mari El (the time interval – from 14 October to 14 April, a photovoltaic module area – 1,3 m 2 with installation angles of 72˚ and 88˚). Because of the simulation, we obtained graphs of the changing the power of the photovoltaic module. Active methods include air injection onto the receiving surfaces of solar energy converters and using of heating elements

THEORETICAL RESEARCH OF AN ENERGYSUPPLYING COMPLEX FOR APIARY BASED ON HYBRID SOLAR PLANT
DescriptionIn the article, we present a simulation mathematical model of an energy-supplying complex of apiary based on hybrid solar plant that establishes the relationship between the design and the operating parameters of the complex with when having conducive winter maintenance of bees. Modeling methodology involves the selection into a mathematical model of multiple levels: level of processes, that directly related with changing of climate parameters inside the hive depending on external factors, level of processes of functioning of the individual components in the complex, which are not directly connected with the processes of changing of climate parameters inside the hive, however, are necessary to ensure favorable conditions for wintering of bees. We have conducted the simulation of the complex based on hybrid solar plant for conditions: the location of apiary in the Republic of Mari El (building for placement of bees for 250 bee colonies, the number of photovoltaic modules – 10, wind power plant area – 18 m2 , the capacity of the battery – 50 A·h, the heat accumulator capacity – 3 m3 , the time interval – from 14 October to 14 April). As a result of simulation obtained graphs of the changing the thermal battery coolant temperature, the voltage at the battery terminals, the power wind turbine and PV modules, the electrical energy consumption

THEORETICAL FOUNDATIONS OF FORMATION OF ENTREPRENEURIAL CLUSTER
DescriptionThis article investigates the development of entrepreneurial cluster set direction to support the creation of innovation clusters in Russia. In the face of increasing international competition, one of the most effective ways of development of small and medium-sized enterprises in the field of innovation is their clustering. We have discussed foreign experience of studying cluster initiatives and events on social development of the regions in the context of sociological knowledge about clusters. We have revealed the meaning of an innovation cluster and the difference between business and innovation clusters. The analysis has shown that a key advantage of the business cluster in relation to the network is the participation of state authorities, as well as functional and territorial factor. On the basis of the author's research we have highlighted a number of problems which solution has been carried out through the creation of business clusters
