DESCRIPTION OF THE INVENTION
The invention relates to the use of wind energy for power generation purposes.
The closest solution designed to solve such a problem, discovered by sources of scientific, technical and patent information, is a wind power plant (VEU) with a thermal motor (Shefter Ya.I., Rozhdestvensky IV Inventor of wind turbines and wind turbines. Ministry of Agriculture of the USSR, 1957, page 122), containing a wind turbine (HP), a heat engine (TD), equipped with a boost compressor and connected through a clutch and a reducer with an electric generator (EG), and a control system adopted as a prototype.
The disadvantage of such a technical solution is the presence of a long transmission shaft for transferring power from the wind wheel to an electric generator, which leads to a significant complication of the design; The presence of an alternating torque on the head of the windmill from the side of the vertical shaft, parrying which complicates the design; Complexity and economic inexpediency of using the unit for working with the network because of the large dependence of the generator's rotation speed on external random factors - wind speed and power consumption; In the case of electric unification (p.121 of the same book) - the presence of two generators and an electric or other synchronization system for their operation, which considerably complicates and increases the cost of installation. In addition, the supercharger takes away part of the power of the heat engine, which does not allow increasing the thermal efficiency of the TD above 0.35 - 0.4.
The object of the invention is to eliminate the above disadvantages and to obtain on this basis an economical installation providing a high efficiency of the heat engine (TD), obtaining high-quality electric power and the possibility of operating the plant on an industrial power grid.
The said task is achieved by a wind turbine with a heat engine comprising a wind turbine, a heat engine equipped with a boost compressor and connected via a clutch and a gearbox with an electric generator, and a control system, further provided with an air turbine and a compressor connected to the wind turbine, the additional compressor being connected by pipelines Through sequentially installed receivers and controlled valves with an air turbine and with a thermal engine, while the shafts connecting the air turbine with the reducer and the heat engine with its compressor are equipped with clutch couplings, and the output of the compressor of the heat engine is provided with a controlled valve.
Comparative analysis of the proposed technical solution with the prototype reveals in it the distinctive features, which allows us to conclude that the proposed installation meets the criterion of the invention "New".
Analysis of technical solutions known from sources of patent and scientific and technical information allows us to draw the following conclusion. In the art, it is known to use air compressed with the help of air for work (Shefter Ya.I., Rozhdestvensky IV The inventor of windmills and wind turbines.-The Publishing House of the Ministry of Agriculture of the USSR, 1957, pp. 130 ... 131, and US Patent N 4498017). However, in the first case, the use of compressed air compressed by the compressor goes either directly to the drive of the pneumatic engine, or to charge the buffer air accumulator for the subsequent replenishment of the missing energy during periods of wind speed failures. In the second case, compressed air is used only as a battery of energy from a wind turbine due to inconstancy of wind speed. In the proposed case, the compressed air compressed by the HP compressor is used to pressurize the TD (for example, the gas turbine), which allows not to expend the energy of the fuel burned in the engine on the operation of its own compressor and thereby increase the thermal efficiency of the engine from 0.35 to 0.4 to 0.7 - 0.85.
Thus, it can be argued that there is a non-obvious cause-and-effect relationship between the totality of characteristics, including the distinguishing features, and the function performed by them and the achieved goal. Based on the foregoing, it can be concluded that the design of the proposed wind turbine does not explicitly follow from the state of the art and, therefore, corresponds to the criterion of the "inventive level".
The invention can be used in power engineering, which allows us to conclude that the proposed design meets the criterion of "Industrial applicability".

The figure shows a schematic arrangement of a windmill with a thermal engine comprising a wind power plant 1 consisting of a wind turbine 2 with an additional compressor 3 and towers 4, a pipeline 5, a receiver 6, valves 7, 8 and 9, a thermal engine (for example, a gas turbine) With the compressor 11 and the clutch 12, the air turbine 13. The output shafts TD 10 and BT 13 are connected through clutches 14 and 15 to a reducer 16, which in turn is connected to the electric generator 17 by its output shaft. |
The installation works as follows. The main operating mode: the compressed air 3 is supplied via line 5 and through the open valve 8 enters the TD 10 which, by burning the fuel supplied to it (not shown in the diagram, through the closed coupling 15, rotates through the reducer 16 an electric generator 17 which generates Electricity supplied to the consumer. In this case, the valves 7 and 9 are closed, the clutches 12 and 14 are open, and the receiver provides smoothing of the compressor power due to uneven wind speed. In the presence of wind and a relatively low power consumption, TD 10 does not work, valves 8 and 9 are closed, 7 is open, clutch 14 is closed, clutch 15 is open. The air compressed by the compressor 3 enters the BT 13, which through the clutch 14 and the reduction gear 16 rotates the generator 17. In the absence of wind, the valves 7 and 8 are closed, the valve 9 is open, the clutches 12 and 15 are closed, the clutch 14 is open. The heat engine operates by receiving compressed air from its pressurization compressor 11 and through the clutch 15 and the reduction gear 16 rotates the generator 17.
