WINTER BEEHIVES ELECTRIC HEATING ADAPTIVE TECHNOLOGY
DescriptionThe article is devoted to increasing beekeeping’s earning capacity with rigging and automation of technological processes. Winter is the most complicated and critical period in beekeeping. It influences on further productivity of bee colony. Winter period has specificity – bees are gathering in winter cluster and sustaining temperature in 24…32 °С range inside. This temperature is depending on fluctuation of outside air temperature. For passing winter without complication electric heating is used. Cluster geometry in winter is changing constantly and for optimal regime of electric heating we need to take it into account. Additionally, bees’ activity changing beehive’s microclimate and it’s important to know when beehive’s microclimate adaptive control system is developed. Conducted researches allow us to get basic equations which characterizes microclimate with taking into account of winter cluster’s variable geometry. The equations establish linkage basic parameters of beehive, winter cluster, internal air between outdoor air. Simulation results may be used for adaptive heating control system programming. Additionally, it may be used in special-purpose software for beehive’s microclimate simulation

AUTONOMOUS HYBRID POWER PLANTS
DescriptionThe 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

AUTONOMOUS WIND POWER INSTALLATIONS AND SYSTEMS
DescriptionThe 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

AUTOMATIC FLAME CONTROL OF INDUSTRIAL INSTALLATIONS
DescriptionThe article describes the modern problem of automatic flame control of industrial installations. The research of this problem is usually begun with the analysis of emergency mode of thermal generating units, divergence of parameters burning processes from accepted value. The most unfavorable factor for trouble-free operation of industrial thermal plants is the cyclical nature of the load changes energy-consuming devices with deep and rapid changes. The paper presents a study of physical factors affecting the stability of combustion in furnaces, the violation of which leads to abnormal flameout. It helps to equip thermal units with effective automatic protection
