THE CONCEPT OF UNINTERRUPTED POWER SUPPLY SYSTEMS

abstract 1191605081 issue 119 pp. 1159 – 1179 31.05.2016 ru 634
We have revealed the main reasons for interruptions in power supply to consumers of electricity. To improve the reliability and the efficiency of power supply for responsible consumers, we have proposed to develop energy efficient combined energy-saving systems for uninterrupted power supply with use of renewable energy sources. The article lists major principles of the development of such systems; it shows the necessity of constructing a generalized schema that contains the possible types and the sources of electric power converters. It also reveals the modern requirements to systems of uninterrupted energy supply. To improve the operational and technical characteristics of the uninterruptible power supply, it has been proposed to use a new circuitry that includes a contactless power generators, the direct frequency converters used to stabilize the voltage and frequency of the current generators of wind turbines, static converters made with the use of single-phase transformers with rotating magnetic field, universal static converters that can operate in the regimes of known types of converters. The article presents features of the modular construction of systems of uninterrupted energy supply and optimization of their structural decisions on key performance criteria. It shows the algorithm of synthesis of structural designs of combined systems of uninterrupted power supply. An important step for further research with the aim of improving operational and technical characteristics of the combination of uninterrupted power supply systems is the mathematical modeling of physical processes in power circuits of the system in both normal and emergency modes of operation

OPTIMIZATION OF A CALCULATION METHOD FOR PILEWORK PROTECTIVE STRUCTURES "STREAMLINED" BY LANDSLIDE CLAY SOILS

abstract 1191605083 issue 119 pp. 1200 – 1216 31.05.2016 ru 576
Expansion and increasing of the Krasnodar region transport infrastructure during the construction of the Olympic facilities together with the new land development created a necessity for construction in the remote areas of landslide slopes with the complex engineering-geological conditions. Constructions of bored piles, jammed by in nondisplaceable soil are often used as one of the measures for the protection of surface rocks landslide movement and tightening the slope weak sections. Such constructive solution is often being considered the best, and sometimes the only acceptable solution. When designing engineering protection it is recommended to consider the use of a number of active protection activities, aimed at the landslide processes stabilization. However, in case of construction production impossibility due to terms of organization, it is necessary to provide passive protection which would secure that the landslide streamlines the construction. Currently, the mechanism of the soil landslides interaction with constructions of detached objects spot protection isn’t studied enough. Known methods adopt simplifications and assumptions which lead to definite significant errors in the design of slope protection structures. Security and reliability of such structures can only be achieved with the adoption of high factor of safety values. This leads to increased material consumption and labor input for the erection of defensive structures also reduces the economic efficiency of these structures. In addition the process of designing protective structures in the Krasnodar region is further complicated by fact that the landslide of construction area is mainly folded by flowing clay soils

COLOR- SENSITIZED SOLAR ELEMENTS

abstract 1191605093 issue 119 pp. 1378 – 1389 31.05.2016 ru 437
Photovoltaic devices are a promising solution to the energy crisis, because they generate electricity directly from sunlight, without producing CO2. While color-sensitized batteries are the most studied element, mainly due to its low cost and high efficiency solar energy conversion into electricity. Until recently, the color-sensitized solar cells performance was less than 1%, however, the use of titanium dioxide as the anode material have greatly raised their efficiency. The advantages of titanium dioxide is primarily in the low cost, but its use provides high light capture efficiency, with external quantum efficiency (efficiency incident photon - charge), usually in the range of 60-90% using nanocrystal forms in comparison with
