“…In addition, within the framework of a modular approach, it is proposed to use aerodynamic control of the blades; creation of a supporting structure as a ring or a hexagon, with the exception of all possible extensions to reduce the resistance and replacement the horizontal traverse with aerodynamic regulators and fairings with traverses of an oval (aerodynamic) shape in section. Another set of proposed solutions in the field of increasing release energy includes the power control by blade turning, aerodynamic control of the rotor speed, drag on the rotor by the ballast resistance and combined intelligent control of the control system complex [26].…”

The use of wind power is one of the most promising ways to obtain renewable energy. In this article, based on a literature review, an analysis of the development of alternative solutions in the field of wind energy is carried out. The classification of wind turbines (WT) according to the orientation of the wind-sensing rotor is given. A comparison is made of the operation of horizontal-axis and vertical-axis wind turbines in different operating conditions. Alternative and unconventional technical solutions in the WT designs and elimination of shortcomings using modern knowledge in the field of application of composite materials and methods of mathematical modeling are presented. It is shown that increasing energy efficiency and release of energy is a key factor in ensuring the profitability of the WT using in various climatic and geographical conditions. The main trends in the WT development, both high-power wind farms and small local WT are determined, including directions for the development of integrated transport networks and energy storage. The tool for the successful introduction of new "green technologies" to the market in modern conditions is marketing-oriented management, which can be implemented through cooperation in the activities of technology start-ups and the state on the principles of mutually beneficial partnerships.

“…This is due to the fact that under such conditions there are large forces acting on the wind turbine blades, which can lead to damage and even destruction. Increased load leads to a decrease in the reliability of the system as a whole [1,2].…”

The object of research is a wind generator with counter-rotating blades. A special feature of this design is the presence of two wind wheels that rotate in opposite directions. Wind wheels are on the same axis, between them there is a certain distance, which is determined based on research data. The problem of modern wind power is the low range of operating wind speeds, weak generation at low wind speeds. The upper speed limit is 25 m/s, exceeding which leads to breakdowns of various units of the wind station, especially this affects the integrity of the blades, rupture of the wind wheel, cracking of the metal parts of the bearings and their fasteners. The wind turbine presented in the article allows to achieve an increase in the generation of electric energy by 50–70 %. This is achieved by increasing the relative rotational speed of the rotor relative to the stator. Therefore, even at low speeds, the rotor speed relative to the stator increases, which leads to an increase in power generation. The design of the device includes: two wind wheels, one transmits its rotation to the stator, the second to the rotor axis, a metal base, a current collector mechanism. For conducting the research, an experimental model and a semi-industrial installation were used. Results studies have confirmed the theoretical increase in the generation of electrical energy by this design. The peculiarity of the obtained results is connected with the determination of the distance between two wind wheels, the optimal distance between them corresponds to the maximum energy generation. A distinctive feature of the results obtained can be considered an increase in the number of blades on the second wind wheel

“…Одной из основных современных тенденций в энергетике является ветроэнергетика, выделившаяся в отдельные отрасли промышленности в нескольких странах, занимающая лидирующие позиции в своем энергетическом балансе и конкурирующая с традиционной энергетической генерацией. Ветроэнергетические установки с вертикальной осью вращения (ВОВЭУ) распространены не так, как ветроэнергетические установки с горизонтальной осью вращения (ГОВЭУ), однако они имеют следующие преимущества: у них ниже стоимость, они имеют более простой (с точки зрения производства) аэродинамический профиль лопасти, меньшие по стоимости монтажа (установки) и обслуживанию [3]. Также для ВОВЭУ не имеет значения направление потока ветра, они не генерируют шумы и инфразвук.…”

Представлено исследование преимуществ и недостатков магнитной левитации ротора ветроэнергетической установки. В мировом научном сообществе представлено много исследований об использовании магнитной левитации роторов ветроэнергетических установок. Однако наблюдаются не только преимущества, но и некоторые отрицательные стороны «магнитного подшипника» в ветроэнергетических установках, что приводит к вопросу о целесообразности применения данного технического решения. Авторами выявлены основания повышенного внимания к магнитной левитации ветроколеса и проанализированы основные подходы к проектированию. Работа включает в себя расчет магнитной опоры и оценку стоимости вертикально-осевой ветроэнергетической установки с магнитным подшипником ротора. Результаты исследования показали, что экономическая эффективность этого подхода крайне низка и не оправдана для использования в коммерческих продуктах. Ключевые слова: магнитная левитация, ветроэнергетическая установка, подшипник.
