DESCRIPTION OF THE INVENTION

The invention relates to the structure and operation of wind turbines, with a wide range of power and the possibility of transition to the regime of thermal power or heat engine.

Known wind turbine rotary vertical shaft / cm. Vol. Windmills. N.Volkov K., M., 1978, p. 5-31 /, containing a vertically mounted rotor with blades rotating from wind pressure.

Wind turbines have a low power density, large size, reaching hundreds of meters in height and rotor diameter of 80-120 m. Their power does not exceed 20 thousand kW. Low efficiency units / not more than 30% / prevents their widespread use.

There are wind turbines and propeller type, containing a screw, tower and accessory / cm. and Prince. K.N.Volkova. Windmills. M., 1978, s.5-31 /. The efficiency of such units does not exceed 20%. When the diameter of the screw in the 100 m plant capacity is not more than 4.0 thousand kW. As a result of widespread use of such units and limited.

The closest analog to the claimed technical solution is rotary type wind turbine comprising a wind turbine with a diffuser body, which accommodates the multistage turbine with nozzle directing apparatuses / 1, 2 /

The aim of the invention is to increase the capacity of wind power through more efficient use of wind energy, and to ensure its operation on hydrocarbon fuels energy during periods of no wind or low speed.

The stated purpose of the invention is achieved by the additional supply of wind power turbine ejector-jet apparatus formed as an annular nozzle disposed coaxially with respect to the housing, and in series with each other are placed multistage turbine, and the last stage is provided with a wind wheel. Also, set the goal of the invention is achieved through the supply of wind power to the furnace air heaters, the compressor and the air duct, and a performance of the working surfaces of turbine blades hat rail.

It is clear from the foregoing that the criterion of "novelty" in the claimed technical solution is the new version of its constructive, described the new set of essential features.

Thus, air entering through the diffuser under pressure wind sequentially transfers its kinetic energy at each stage of the engine, causing the utilization of wind energy, and thus ultimately increases the capacity of the entire wind power repeatedly. Given that the goal set in the present invention the goal is realized through a new set of essential features, namely an additional installation on the wind turbine wind farm ejector constructed in the form of an annular nozzle disposed coaxially relative to the body, but also by placing the multistage turbines in succession, legitimate conclusion according to the claimed technical solution to the criterion "industrial applicability".

Wind power plant consists of power plants, engines 1 / FIG. 2, 3/2 and a wind turbine tower has one /fig.1/ flow part comprising three guide nozzle apparatus comprising a group of guide nozzles 4 arranged uniformly over the circumference of the engine with its guide 5, a turbine 6, active type / Figure .5 / s wide and long blades 7, block 8, the diffuser 9, the gearbox 10 and electric generator. The working surface of the turbine blade has a trough-shaped cross-section. Last stage of the engine is running or by installing propeller 12 / FIG. 1.4 / s common location on the blades 13 shroud 14 coupled to the bearing 15 by the spokes 16 and the shaft 176, or alternatively, instead of the propeller may be mounted in an annular ejector nozzle 18 at the end of the housing. By walls 19 of the nozzle 20 are mounted racks in which the bearing housing 21. The turbine situated has /fig.1/ pylon 22, via which the motor is pivotably suspended from the beams 23 /fig.3/ tower 2. The nozzle 18 is fixed to the housing 8 via gussets 24 /fig.1/. The diffuser of the engine is installed in a ring ejector nozzle 25, periodically connected to the air heater 26, having a furnace. Area 27 of the diffuser nozzles 25 during installation / if the wind turbine is designed for the combined mode / a mixing chamber between the cold and hot air coming from the suction through the open end of the diffuser 9. Air entering the combustion chamber 28 annular slots 30 are. combustor diffuser mounted on the circumference at a predetermined distance from each other and from the walls. By the uprights 20 of the engine 31 mounted console with a platform for mounting the gearbox 10 and the generator 11. The tower contains columns / pillars in the form of a / 32, the beams 23 and the cross bar 33, bearing 34 air heaters have a one- or two-stage compressor 35.

Wind power plant works as follows

During the work on the wind power station engines 1 installed on the wind with the help of an electromechanical actuator and sensor / not shown /. As a result of wind forces air enters the flow multistage turbine engine part where the kinetic energy of wind is converted into mechanical energy of the shaft 17 which in turn drives the gearbox 10 and the generator 11. Using the output of the air speed of the first turbine stage to the second and subsequent provides increased efficiency of wind energy and additional placement on the body 8 multistage turbine / jet apparatus ejector 18 / formed as an annular nozzle disposed coaxially with respect to the housing, can significantly increase air velocity at the blades 7 hat rail active type 6 turbine and significantly increase the capacity of a multi-stage turbine. Purchasing proposed design wind turbines located on a multi-storey tower, allows their use as a gas turbine. This is necessary when there is no wind or low speed. For this purpose, a tower is installed with the furnace air preheater and a single or two-stage compressor for supplying compressed air to a tubular air heater. In this case compressed and heated air in the absence of wind motors fed by a pipeline and into the annular nozzle / engine ejector / installed in the diffuser, is mixed with air sucked from the engine a diffuser, the turbine is supplied. In this part of the turbine power generator is supplied to the network, and another part of the compressor motor shown air preheater station.

If necessary, forcing the engine (e.g., to increase capacity) are installed in the diffuser 28 of the combustion chamber.

Purchasing the latest multi-stage turbine wind wheel and enhances the power of a wind turbine, since both devices - ejector and propeller uses the same energy source - the air flow around the casing multistage turbine.

It is known that by increasing the air velocity V of the turbine blades increases twice to eight times the power of wind turbine due to power known in the art, depending on the air flow rate in the third degree:

N = 0,000833 · F · V 3· E · K I,

where E - wind utilization rate;

K I - mechanical efficiency

Therefore, by increasing the velocity of air, for example, 5 m / s to 6 m / sec in the engine power is increased n = 6 3/5 3 = 216/ 125 , i.e. more than 1.7 times.

Furthermore, with increasing wind speed is the height H increases in the following relationship:



where V 10 - the wind speed at the height of the weather vane;

m - exponent, depending on the class of atmospheric stability and evenness of drying (m = 0,17-0,24).

As a result, consistent layout engine height of the tower 2 provides a significant increase in their power to high and a significant increase in power throughout the wind farm.

An important feature of the combined power plants is the ability to generate electricity when the wind is not only, but also when a small or no velocity by the use of conventional hydrocarbon fuels energy.

This feature WEC operation eliminates the dependence of power generation from wind and from auxiliary engines and generators or bulky power batteries used in existing wind turbines during periods of calm.

In both cases, the nozzle 25 and the jet nozzles are the working machine 28 of the combustion chamber, as is the cone 27 and the chamber 9, which provide injecting air through inlet diffuser 9.

The use of wind power new design provides:

- The ability to work and produce electricity when the wind blows, not only, but also for its complete absence or low speed;

- A high wind energy utilization ratio greater than 80%, provides a higher power density of wind turbines as compared to any known type of analog or prototype by applying not only the multi-stage turbine, and the jet device and the last stage of the turbine in the form of propeller;

- Considerably higher power wind turbines windfarm compared to the prototypes and analogues, mainly (by comparison with the prototype) as a result of air flow energy generated by the wind flowing around the motor housing;

- The location of wind turbines in the multi-storey tower allows you to implement and use to increase the capacity of wind power plants feature movement, which increases the speed monotonically with altitude;

- In general, the annual WEC work balance (on wind energy and fuel energy) achieved a significant reduction in emissions into the atmosphere of solid, liquid and gaseous substances that contribute to air pollution and the greenhouse effect, and heating and environmental protection of waste heat inherent in a purely thermal power plants. It achieved the most effective use of wind power in conjunction with the use of natural fuels;

- A high speed air flow at a wind turbine flowing part of the multistage ejector by utilizing the turbine can increase the speed and thereby utilize electric generators with lower cost (simplified or gear);

- A clock "peak" electricity load in a network it is possible to boost engine power and increase in their work in the gas turbine operation;

- High power density of wind turbines provides less metal content and WPP compactness and the absence of auxiliary power units, electric power generators during periods of calm, on the basis of diesel engines or different bulky battery energy - reduces the cost of construction of a wind power plant and the cost of one kilowatt-hour during operation
