This article presents a methodology for assessing the gross, technical and economic potential in the territory of the Bukhara region. Locations with high wind and hydropower potential were identified in the region, and the introduction of wind and micro-hydroelectric power plants was analyzed. According to the results of the study, the importance of wind and hydropower in the development of the socio-economic sphere of remote areas of the Bukhara region was studied.
This article analyzes the literature on the choice of generators for power devices that can work effectively with wind and water currents in the climatic conditions of Uzbekistan. In most of the territory of our republic, low-speed winds and water currents prevail. Efficient use of these flows makes it possible to save fuel and energy resources and thereby reduce the emission of CO2 gas into the atmosphere. Based on the analysis of the literature, the factors of using an electric generator capable of operating efficiently even at low rotation speeds are analyzed. The article deals with scientific research carried out in recent years on generators with radial and axial magnetic flux
The article analyses generators generating efficient electricity at low speed water and wind flows. High rotating speed generators are used in wind farms and micro-hydropower. Reduction gears are used to provide the generators with the required number of rotations. The use of reduction gears in the power system leads to a decrease in the efficiency of the system and additional capital costs. The study analyzed multipolar synchronous generators. Both generators used a permanent magnet to generate electromotive force, and the generators are distinguished by the radial and axial placement of the permanent magnets. In order to analyze the generators, virtual models were created and analyzed in the Ansys Maxwell program. The Ansys Maxwell program is used to analyze electric machines in the electromagnetic field. The use of these programs in determining the optimal size of new devices is of great importance in saving time and improving cost-effectiveness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
