Development of civilisation requires a significant consumption of electricity. Nowadays, traditional ways of power generation arouse harsh criticism aimed at emission of large amounts of carbon dioxide in the process. In this connection, the role of renewable energy sources (RES), such as hydroelectric power plants, solar panels, and wind turbines, is increasing.
Each type of RES has both positive and negative properties. In the wind power industry, a crisis is looming due to the following problems:
-
in the most of existing wind turbines, power generation stops when wind speeds are high;
-
extensive electrical networks are required to deliver energy;
-
fibreglass components of wind turbines are practically impossible to be recycled after disposal;
-
wind turbines pose a great danger to birds, animals, and humans due to open rotating parts and generation of infrasound.
Our company "Anter" has developed the design of a vertical axial, small scale, double-rotor wind turbine which does not have the above mentioned disadvantages.
The main design feature of our turbine is two coaxially positioned rotors with a vertical axis, the rotors rotating in a stationary housing (Fig. 1).
The table shows some technical parameters of the wind turbine.
Each wind turbine is equipped with a controller with integrated sensors (partially-AI) allowing the turbine to perform self-testing. All data are transferred to the cloud storage for the service department.
Competitive advantages of our wind turbine:
-
No large areas for installation are required;
-
No limitations on the maximum wind speed;
-
No extended electrical networks are required;
-
No large initial investments are required;
-
Power generation can be increased as needed;
-
Safety for people, birds, and animals;
-
All components can be recycled upon disposal.
Based on these advantages, various options for application of wind turbines are possible:
-
Wind turbines can be installed both as a single unit and as a component of a wind farm (Fig. 2) consisting of several wind turbines. All wind turbines operate independently. Bigger clusters can be formed of such wind farms – distributed microgeneration networks (Fig. 3);
-
Wind turbines can be installed in the immediate vicinity or on the roof of residential buildings;
-
They can be installed in distant and isolated areas, such as tundra, marshlands, deserts, islands, and mountains; in the areas of compact settlements, as well as in places of operation of geological field parties, and armed forces units;
-
Wind turbines can be installed along highways;
-
They can be placed on river banks, on coasts of large water bodies (such as lakes, seas, oceans).
As it is known, the wind load is higher at heights of more than 40 meters above the ground level. Thus, the most promising locations for the installation of our wind turbines can be as following:
-
On the facades of high-rise buildings (more than 50 meters high);
-
On the stack of CHP plants which are put out of operation. In this case there is no need to dispose of a large amount of concrete, which, among other things, can be radioactive.
The design of the wind turbine and methods of its application are patented in Russia, and the process of foreign patenting is underway.
