The present invention relates to a wind turbine plant, a wind turbine power generator, and a method for operating a wind turbine plant.

2. Description of the Related Art A large number of wind turbine generators are arranged to drive a generator by a wind turbine that applies a wind force to a plurality of blades attached to a wind turbine shaft to generate a rotational force, thereby providing a high output power generation capacity. The equipped wind power generation equipment is
It is installed in high places such as on hills and mountains, or in places where high wind speed can be obtained, such as offshore. Such a wind turbine power generator is usually controlled to change the pitch of blades attached to the wind turbine shaft in accordance with the wind speed energy and power consumption (necessary generated power) during operation to maintain the required generated power. .

Further, in such a wind turbine power generator, the output surplus of the generated power exceeds the consumed power (necessary generated power) such as at night when power consumption is low or when wind energy is high at high wind speed. Levels the output (electric power) of the power generator when the electric power generation cannot cover the electric power consumption (necessary electric power generation) such as when the wind power is low and the wind power is low at high wind speed and low wind speed. To achieve this, we have installed a flywheel device with a large diameter flywheel that can be rotated in a vacuum. The output of the wind turbine is accumulated as the rotational energy of the flywheel when the output is surplus, and the rotational energy accumulated in the rotational energy is released to the generator when the output is insufficient to increase the generated power.

Various wind turbine plants utilizing the wind energy of the wind turbine have been proposed, and one of them is the invention of Japanese Patent Laid-Open No. 2000-202441. In this invention, a plurality of reverse osmosis membrane seawater desalination devices are driven by using the power generated by the wind turbine power generator as a drive source, the number of operating seawater desalination devices is determined with respect to the output of the wind turbine power generator, and the storage battery is used. Is used and the control operation is performed, and in addition, the seawater to the seawater desalination apparatus is heated with surplus power.

A flywheel device equipped with a large-diameter flywheel is installed, and the output of the wind turbine is accumulated as the rotational energy of the flywheel when the output is surplus, and the rotational energy accumulated in the rotational energy is output to the generator when the output is insufficient. It is designed to be released to increase generated power. Therefore, in such a conventional technique, it is necessary to install a large and heavy flywheel device, so that the device becomes large,
Further, since a device for obtaining a high degree of vacuum, such as a vacuum pump or a sealing means, is required in order to suppress the friction loss of the flywheel to a minimum, the device becomes complicated and the device cost also increases.

Further, in the invention of Japanese Patent Laid-Open No. 2000-202441 relating to a wind turbine plant utilizing wind energy of a wind turbine, a generator is driven by the wind turbine, and a plurality of reverse osmosis units use the generated power as a drive source. Since the membrane type seawater desalination system is driven, it requires a power generation facility including the above-mentioned generator and a device for converting electric power into energy for seawater desalination treatment. . Further, according to the present invention, since it is necessary to adjust the wind power fluctuation in the wind turbine power generator by the pitch control of the wind turbine and the generated power control, the method and device for adjusting the wind power become complicated.

In view of the above-mentioned problems of the prior art, the present invention provides an output (electric power) at the time of surplus output at night and at the time of output shortage at daytime by using a device having an extremely simple structure and a small size and low cost.
To provide a wind turbine power generator capable of leveling

Reference numeral 14 denotes a clutch provided on the connecting shaft 16 for disconnecting power transmission between the connecting shaft 16 and a compressor shaft 17 which is a rotating shaft of the air compressor 21.

Reference numeral 22 is a compressed air tank, which is connected to the air outlet of the air compressor 21 by an air pipe 26 and stores the compressed air generated by the air compressor 21. The air outlet of the compressed air tank 22 is connected to the air passage 4 of the wind turbine 1 by an air pipe 24. Reference numeral 23 is a compressed air valve provided in the air pipe 24 to open and close the air pipe line.

Reference numeral 27 is a wind speed detector for detecting the speed of air acting on the blades 2 of the wind turbine 1, that is, the wind speed, and 28 is a timer for setting the time for operating the air compressor 21. A controller 30 receives a wind speed detection signal of the wind turbine 1 from the wind speed detector 27 via a line 29, and a set value of the operating time of the air compressor 21 from the timer 28. Then, the controller 30
A control signal output from the transmission device is transmitted to the clutch 14 via a line 33, to the air compressor 21 via a line 31, and to the compressed air valve 23 via a line 32 to control these devices. It has become.

In the wind turbine generator having the above structure, when the power demand during daytime operation is high and the required power supply from the generator 20 exceeds the set required value, the controller 30 disengages the clutch 14. And the air compressor 21 is stopped. As a result, all the rotational force of the wind turbine shaft 9 due to the operation of the wind turbine 1 is transmitted to the generator shaft 15 of the generator 20, and all the wind energy of the wind turbine 1 is supplied to the generator 20.

When the output surplus of the wind turbine with a small power demand such as at night is exceeded, that is, when the generated power supplied from the generator 20 exceeds the required power, the controller 30 sets the air compressor set in the timer 28.

The excess output is stored as energy of compressed air, and when the power demand is high and the output of the wind turbine 1 is insufficient, the compressed air in the compressed air tank 22 drives the centrifugal discharge type wind turbine 1 to compress the compressed air. It becomes possible to increase the power generated by the generator 20 to the required power by superposing the energy of the air to the output of the wind turbine and superimposing it on the rotational force of the wind force acting from the outside.

As a result, the output energy of the wind turbine that fluctuates due to the natural wind can be mitigated, and the output fluctuation of the wind turbine 1 can be reduced. Further, by recirculating the output energy of the wind turbine 1 stored as the energy of the compressed air at the time of low power demand at the time of high power demand, it is possible to stably supply the required generated power.
