The invention relates to the field of wind energy and can be used to generate electricity.

The famous design of the generator mounted on the tower rotating propeller, is th [2] to facilitate start-up at low wind speed.

These wind turbines have a magnetic system of generators of the traditional type.

Known analogues closest to the claimed combination of essential features is the wind turbine [3], which contains a rotatable wheel, a magnetic system with the windings in the gap which moves the rotor, and a magnetic system (stator) is located on the base, placed in the lower position of the blades, and the blades are equipped with ferromagnetic toothed plates constituting the rotor, the rotor thus covers the ends of the blades, plates pass through the air gap of the magnetic system.

The disadvantage of this wind turbine is that it can only be used with the propeller of any single type: slow (multi-blade low speed and large starting torque) or fast (mallapaty low starting torque). This design significantly limits the functionality of the unit, since it is able to generate rated power only in a narrow range of wind speeds, but in reality, this range is wide enough and it may be a situation when long work sloth

The invention is aimed at achieving functionality, in particular the wind power in a wide range of wind speeds.

This is achieved by the fact that in contratarem the wind power, containing a tower with swivel base and the device installed on the wind, based on the axis fortified bladed propeller, in the area of the lower position of the blades is the stator, the rotor blades installed ferromagnetic plate, passing through the air gap of the stator, according to the invention on the same axis fortified low-speed and high-speed wheel opposite directions of rotation, and speed of the wheel is located ahead of the low speed by wind direction and fitted with plates, oriented from wind, low-speed wheel fitted with plates, oriented towards the wind, and between the plates of wheels placed the stator.

The invention is illustrated by the "blueprints", where Fig.1 shows a wind power (side view), Fig.2 is a front view, Fig.3 shows in larger scale the execution of the stator with the upper and lower rotors in position, when the lower rotor perimice pole, and the top - not perimice.

is that installed on the rotary base 4, on the basis of fortified device installed on the wind 5 (tail blade), on the basis of fortified axis 6, which is fixed in the bearing low speed wind wheel 7 with ferromagnetic plates 8 and high-speed wheel 9 with ferromagnetic plates 10. To the base is also attached to the rod 11, the lower end of which is in the area of the lower position of the blades is the stator 12. In Fig.2 shows a high-speed two-bladed wheel and low-speed four-bladed wheel with blades extended. The stator includes a core 13, the pole pieces 14, the field winding 15, the generator coil 16, a winding provided with pins 17, which are connected to the load.

Antrotomy wind power works as follows. When the charge air flow (from right to left, as shown in Fig.1) high-speed wheel is driven in a certain direction, for example clockwise. Under the action of the residual wind speed wheel 7 also comes in rotation but in the opposite direction, as fast the wheel is located ahead of the slow-moving in the direction of the wind. As can be seen in Fig.1, a high-speed wheel provided with a ferromagnetic plates intended is treco wind, when placed between the plates of the stator. In the core 13 and the pole pieces 14 of the stator under the action of the magnetizing force of the winding 15 there is a magnetic flux, which is switched high-speed wafer 10 (2 pieces as shown in Fig.2) and low-speed wafer 8 (4 pieces). As a result, the coil 16 will be picking up the voltage, which is then passed to the consumer.

The advantage of this contrating of wind power is its wide functionality, namely, that he is capable of capturing energy as low-grade wind flow when rotating the wheel 7 and the fixed wheel 9 and the high-potential wind flow when turning both windwheels.
