The object of research in the scientific article is the process of converting wind flow energy into mechanical energy. The process of converting wind energy into mechanical energy is carried out by two counter-rotating wind wheels. And into electrical energy in the generator, with the armature and inductor rotating in opposite directions. The purpose of the scientific article is to study and develop an efficient power supply system for autonomous consumers based on a wind power plant of a special design with an increased wind energy utilization coefficient. In the course of the work, the main parameters of a special-designed wind turbine with counter-rotating wind wheels were determined and the process of electric generation was modeled on the principle of counter-rotation of the armature and generator inductor; a physical model of a special-designed wind turbine based on a two-wheeled system located in the same wind flow and providing rotation of the armature and generator inductor individually from each wind wheel in the opposite direction was developed; a design documentation on the basis of which the experimental design sample was made; experimental studies of the experimental design sample of a wind turbine were conducted to determine its main parameters for the purpose of efficient power supply to autonomous consumers. Main design and technical and economic indicators: optimization of wind power plant parameters, dimensions of wind wheels, their relative location, as well as generator power depending on the expected wind speed. The degree of implementation lies in the fact that a wind generator with variable torque of a wind wheel is patented (patent for invention of the Republicof Kazakhstan No. 36903; Eurasian patent for invention No. 047230). The effectiveness of the research lies in the application of technical solutions patented by the authors in practice, which makes it possible to increase the energy efficiency of wind turbines. Scope of application of the developed wind turbine of special design in the field of alternative energy and decentralized agricultural consumers.
