Description

The invention relates to wind energy and can be used to produce electrical energy.

A known wind station in which a wind wheel is connected to an electric generator and to an electric motor using a belt drive (patent RU 2249721 C1, IPC F03D 3/04, publ. 10.04.2005. Bull. No. 10). The electric motor spins the wind wheel to the required rotation speed.

The disadvantages of such a station are the mandatory presence of an external source of electric energy (power lines), low power.

Known wind power installation (patent RU 2251022 C1, IPC F03D 3/00, 3/04, publ. 04/27/2005. Bull. No. 12), containing a wind wheel, an electric generator, an energy storage device (battery) and a photoelectric light energy converter. Uninterrupted operation of the installation is ensured by a photoelectric converter and a battery.

The disadvantages of such a wind power installation is its low power, short operating time in adverse weather conditions.

The closest in technical essence is a wind farm (patent application RU 2005119907 A, IPC F03D 9/00, 06.27.2005, publ. 10.01.2007. Bull. No. 1), containing a wind wheel, a direct current generator and an internal combustion engine. Uninterrupted operation of a wind farm is ensured by an internal combustion engine connected to a direct current generator through a coupling. However, the power plant generates a DC voltage, which makes it difficult to convert and transmit electrical energy. The disadvantages also include the small capacity of the wind farm.

The problem to which the invention is directed, is to create an autonomous wind power plant of high power for use in remote and northern regions, while maintaining operability even with weak wind flows.

The task is achieved in that the wind farm containing wind propellers, electric generators, internal combustion engines, electrical equipment, in contrast to the prototype, is made in the form of a ring railway equipped with overpasses, snow blowers and collector wires, with the rolling stock of the bogies located on it controlled wind propellers, electric generators connected to current collectors, internal combustion engines, providing acceleration and movement of the composition at weak bom wind flow, and on the trolleys placed ballast to increase the mechanical energy stored by the composition.

In addition, wind propellers can be made sailing type.

The power plant is equipped with measuring, controlling and regulating devices. Inside the railway ring there is a transformer substation, storage and other premises.

Figure 1 schematically shows a General view of a wind farm. Figures 2 and 3 show a cart with a wind turbine and a generator cart.

On the ring railway 1 there is a rolling stock of bogies 2 with driven wind propellers 3 and bogies-generators 4 with generators 5 and internal combustion engines 6. On the inner side of the railroad there are current collection wires 7 to which current collectors 8 are located, located on carts- generators 4.

Wind power works as follows.

In the presence of wind, the wind flow is perceived by the wind propellers 3 and sets the composition in motion. With the passing movement of the carts 2 with the direction of the wind, the propellers 3 located on these carts are directed so as to perceive the wind pressure and provide the speed necessary to generate a current of industrial frequency, with the counter so that the wind pressure on the propulsors 3 is minimal. The wind energy in this case is converted into mechanical (kinetic) energy of the movement of the composition. Ballast 9 on trolleys 2 serves to increase the mass of the composition and, accordingly, to increase the kinetic energy stored by the composition. The mechanical energy of movement in the generators 5 is converted into electrical energy of alternating current of industrial frequency. Electric energy is supplied to the transformer substation 10 through current collectors 8 and current collection wires 7.

With a weak wind flow, uninterrupted operation of the wind farm is ensured by internal combustion engines 6 located on the generator carts 4, which maintain the required speed of the train. Internal combustion engines 6 can also be used to disperse the composition.

The number of wind propellers 3, generators 5, internal combustion engines 6 is selected based on the required power of the power plant and the mass of the composition.

Management of wind propellers 3 during movement, turning on and off internal combustion engines is carried out by measuring, controlling and regulating devices depending on the direction and speed of the wind, the direction of movement of each specific carriage relative to the wind flow, the speed of the train.

The increase in power of the proposed wind farm is provided by increasing the number of wind propellers, uninterrupted supply of electrical energy to consumers is ensured by internal combustion engines and due to the large amount of mechanical energy stored by the composition.
