The invention relates to the field of electricity and can be used for electricity generation.

One of the promising directions of development of renewable energy is wind energy. The use of wind energy not only helps to solve many problems of energy supply and to gain independence from the local power supply companies. Even when connected to a network of centralized power, the use of wind energy for your needs will also be useful because the network receive electricity by burning coal, oil or gas or even nuclear power plants. Side energy that do not affect the basic process, will allow to increase efficiency of devices used.

Known for its practical use of the device is a propeller type, repeating medieval windmill.

Disadvantages propeller devices are:

- need to increase the diameter of the propeller to increase the power extracted from the wind flow;

- propeller installation for effective work on weaning wind energy should provide a permanent reversal in the direction of the wind;

the use of these plants propellers with mechanisms for changing the angles of attack of the blades makes them very expensive.

The closest technical things the spine is the air-piston power plant (published in Bulletin of Inventions No. 2009126243 from 2011.01.20), the principle of operation is based on the use of a piston effect.

Object of the invention is a device for producing electricity by artificial means, a differential pressure of air in the wind tunnel and effective convert various ways into electricity.

The technical result is achieved in the tunnel power plant, consisting of an air turbine with an electric generator, in communication with the air intake, located on the perimeter of the upper part of diametrically cut tunnel, the shape of the upper part and the outlet of the duct system and air valves, and piston used at passing vehicles, according to the invention with the left and right sides of the tunnel system installed rotary wind turbines with a vertical axis of rotation, is connected to the load through the control system, nakaplivalsya and distributes the electricity produced.

Tunnel power plant consists of a generator, connected to an air turbine, in turn, connected to the air intake, located on the perimeter of the upper part of diametrically cut tunnel, repeating its shape. The discharge air from the turbine duct is equipped with a system of air valves. The left and right sides of the tunnel, its the same area, between travel cover (W/W path, asphalt and the like) and the air intake system installed rotary wind turbines with a vertical axis of rotation, is connected to the load through the control system. As the piston tunnel power plant are passing vehicle.

The invention is illustrated by drawings, where figure 1 shows a possible version of the construction of the tunnel system of power plants, which contain:

1 - wind tunnel

2 - air inlet with the outlet duct,

3 - piston

4 - system rotary wind turbines with a vertical axis of rotation.

Figure 2 and figure 3 shows a variant of the device separate tunnel power plant, where

5 - air turbine with generator,

6 - control system

7 - air inlet valve

8 - outlet of the air valve.

Tunnel power plant operates as follows: when the piston (3) air tunnel (1) increases the level of air pressure before working surface, a so-called piston effect. The incident wave is captured by the inlet with the outlet duct (2)located in the tunnel along the perimeter of the upper part of diametrically cut tunnel, repeating its shape, spins standing on the left and right sides of the system is neither rotary wind turbines with a vertical axis of rotation (4), the energy produced through the control system (6) is communicated to the consumers. When the level increases, the pressure in the duct is triggered inlet air valve (7) and the air supplied to the air turbine blades connected to a generator (5)developed thus electricity in a similar way through the system control is passed to consumers. Excessive voltage at nevostrebovani consumers, is returned to the grid. The direction of movement of air through the turbine is controlled by air valves. When the pressure increases, with the approach of the working surface of the piston to the exhaust air valves (8), the valves which operate to close, preventing the flow of air to the turbine. After the passage of the piston are formed of a sparse pressure, and exhaust valves open as the achievement level threshold pressure between the intake and exhaust valves. Thus, there is a possibility of pressure equalization in a separate section through a lateral duct containing an air turbine with a generator.

Tunnel power plant will find its use in the system of tunnels, road and rail tunnels, even in Elevator shafts, where the pressure piston (train, car, cubie is s / Elevator, etc.) there is an increase in air pressure, the so-called piston effect, the incident wave is captured by the inlet to the duct (2), rotates the rotor blades of wind turbines and converts the energy of the air flow in the electric power needed by the consumers.

Tunnel power plant containing an air turbine with an electric generator provided with air intake located but the perimeter of the upper part of diametrically cut tunnel, the shape of the upper part and the outlet of the duct system and air valves, and piston used the passing vehicle, characterized in that the left and right sides of the tunnel system installed rotary wind turbines with a vertical axis of rotation, is connected to the load through the control system, nakaplivalsya and distributes the electricity produced.
