Description

The present invention relates to a system of a wind turbine generator that uses artificial wind to supply only the amount of power required for the generated demand as a drive source.

The conventional technology considers that the changing wind speed cannot be controlled, and obtains the maximum efficiency generator output from the wind speed. Therefore, it grasps the generated demand and generates the necessary amount of generator output. Until now, there has been no wind power generation system that adjusts the output of the generator by controlling the wind speed and the pitch drive mechanism to match the demand and the output of the generator.
The technology that can be referred to is Patent Document 1 (Japanese Patent Application No. 2007-79909) that determines the output amount per unit time of each generator so as to minimize the operating cost of all generators on the power system including wind power generation. From the converter of Patent Document 2 (Japanese Patent Application No. 2006-69915), which adjusts the pitch angle by the pitch drive mechanism and adjusts the rotation speed to change the output amount of the generator in response to the changing wind speed. Patent Document 3 (Japanese Patent Application No. 2005-77048) discloses a technique for changing the output amount of the generator by adjusting the rotational speed by issuing a torque command that increases the torque command value by a small amount.
Patent Document 1 predicts the generator output of wind power generation based on climate forecasts, etc., and minimizes the operating cost of all generators on the power system including wind power generation. This is a method for determining competence.
In Patent Document 1, first, the total demand is predicted, and the generator output from the base generator is first subtracted from the demand, and then the generator output of the wind power generation predicted based on the climate prediction is subtracted. This is a system in which the remaining demand is supplied by an increase / decrease operation type generator and the operation cost of all generators is minimized by determining the optimum output amount per unit time of the increase / decrease operation type generator.
The difference between Patent Document 1 and the present application is that
In Patent Document 1, it is assumed that not only wind power generators but also other power generators are used to respond to demand, so that the wind power generator itself can respond to demand only by the wind power generator. It is not a technology to increase or decrease the generator output.
In this application, it is assumed that the response to the demand is handled only by the wind power generator, and the generator output of the wind power generator itself is increased or decreased by changing the wind speed.
(B) In Patent Document 1, the demand amount is predicted, whereas in the present application, the demand amount is actually generated.
Patent Documents 2 and 3 are not technologies that target artificial winds but technologies that target natural winds, but the subject matter of this application is “Electricity in the case where all demands are ranked up by new demands”. Assuming that the technology used in Patent Documents 2 and 3 is applied to the “supply system”, the differences will be described below.
In the present application, the total amount of electric power (31) actually supplied in the building and the new demand amount (32) of the application for use are summed as the total demand amount (33) actually generated, and the rank classification ( 34), when the rank classification is increased, the wind speed is changed to a wind speed that can supply the total demand (33), and the first shaft 8a is 5% higher than the rotation speed of the excitation circuit in the pitch drive mechanism. Adjust the pitch angle of the propeller 6 so that it starts to rotate.
The first shaft 8a, which has started to rotate in the vicinity of the number of rotations 5% higher than the number of rotations of the excitation circuit, rotates at the number of rotations indicated by the hybrid excitation circuit, and is increased by the first speed increaser. Generate electricity.
The generated electricity is measured by the generator output measuring instrument, and when it is determined to be appropriate, the use of the new demand (32) is permitted.
The difference between this application and Patent Documents 2 and 3 is
C. In the present application, after confirming the change of rank classification, after the system that can supply the total demand (33) is created, the use of the new demand (32) is permitted, so a supply shortage cannot occur.
In Patent Documents 2 and 3, even if an attempt is made to increase the generator output by adjusting the pitch angle with a pitch drive mechanism or issuing a torque command in which the torque command value from the converter is increased by a small amount, there is a new demand. Since the total demand amount (33) that increases when the amount (32) is used is not grasped, the necessary wind speed is not known, so the wind speed cannot be increased, and supply shortage occurs.
A conventional wind power generator is a type that operates when wind blows regardless of changes in demand.
Since this technology also originated from the idea of how to maximize the generator output, a wind speed that changes every moment is given, and many techniques have been developed to adapt to that wind speed.
For example, pitch control that detects wind power / generator output, changes the blade angle, controls lift, and controls the rotation of the propeller is a typical example.
Although demand varies greatly depending on the season and time, the biggest feature of wind power generators that use artificial wind as the driving source is that the wind speed can be controlled, so it is necessary for the generated demand by changing the wind speed. If there is a system for wind power generation that supplies a certain amount of electricity, it will be meaningful from the operational cost, the useful life of the equipment, etc.
Japanese Patent Application No. 2007-79909 Japanese Patent Application No. 2006-68915 Japanese Patent Application No. 2005-77048

Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a system for wind power generation that supplies electric power in an amount necessary for the generated demand.

The sum of the amount of power actually supplied in the building (31) and the new demand amount (32) of the application for use is captured as the total demand amount actually generated (33), and the rank classification (34) is obtained. If the rank classification (34) is one rank higher than the conventional rank classification, change to a generator output with a wind speed of 1 m faster than the current wind speed, and confirm that the supply is made reliably, Allow new demand,
When the use of electric power is stopped and the rank category of the total demand (33) actually generated is reduced by one rank from the conventional rank category, the generator output is changed to a generator output with a wind speed 1 m slower than the current wind speed. To solve the problem.

The basis for dealing with power energy that is difficult to stockpile is that you only need the power you need, but current wind power generators operate regardless of changing demand, so demand There is always a gap in supply, and the most important issue is how to eliminate this gap.
In the present invention, since the total demand (33) of the generated electric power is ranked (34) and the generator output of the wind speed capable of supplying the total demand (33) is supported, the highest efficiency is achieved. A good supply system is provided. If the present invention is installed in a building with demand, the advantage of eliminating the gap between the generated demand and supply by combining the data of the total demand (33) and the generator output of a plurality of wind turbine generators. have.

Rank rank is Ym / s when the cut-in wind speed at the wind speed sensors 5a to 5d is less than the generator output when the wind power is Ym / s. When the wind speed (Y + 1) m / s is smaller than the generator output at the time of wind speed (Y + 1) m / s, it is set as rank category 2, and the number of rank category increases by 1 every time the wind speed increases by 1 m / s.

The rotation sensor and the pitch drive mechanism are operated in advance, and the air volume information from the fans 4a to 4d and the appropriate wind speed data at the points of the wind speed sensors 5a to 5d are obtained in advance for each wind speed category.

The air flow is adjusted to an appropriate level, and the rotation speed of the propeller 6 is adjusted by the pitch drive mechanism and the rotation sensor so that the rotation speed always starts in the vicinity of a constant rotation speed in any wind speed section.

(Power supply of the present invention)

I will explain it.
When L is an integer and the electricity demand requires L wind turbine generators, (L-1) wind turbine generators generate power at a cut-out wind speed of 50 m / s, and the L th wind tunnel With this generator device, the supply system of the present invention for generating electricity by changing to a wind speed that can be supplied with respect to the electricity demand that has been ranked is implemented.
Since the L generator devices have the same configuration, the description of the (L-1) wind tunnel generator devices will be omitted, and the supply system for the L-th wind tunnel generator device will be described. .

(Device and name of the present invention)
The pitch control in the present invention is used to mean “a device that detects wind speed and generator output, changes the angle of the propeller, controls the lift, and controls the rotation of the propeller”.
In the present invention, the direction of the second generator from the blower is leeward, the rotation shaft from the rotor head of the hub to the first speed increaser is the first shaft 8a, and the rotation axis from the first speed increaser to the first speed increaser is the first. The rotation axis from the first generator to the second speed increaser of the horizontal axis in which the one shaft 18b and the first shaft 18b are extended is the rotation from the second shaft 21a and the second speed increaser to the second power generator. The shaft is called the second shaft 23b.
As shown in FIG. 1, there is a cylindrical wind tunnel body having the same inner diameter from 1 part to 2 part, 1 part is closed, 2 part is opened, and the wind of the blower is discharged from 2.
Inside the wind tunnel body, as shown in FIG. 1, a blower support ring 3, blowers 4a to 4d, wind speed sensors 5a to 5d, propeller 6, rotor head 7, pitch drive mechanism (hydraulic system, not shown), first shaft 8a, a first shaft 8a, a stator 11 provided with an electromagnet 10 in which a wire is wound around an iron core in a concentric ring 9 installed between the rotor head 7 and the first speed increaser 17, A hybrid excitation circuit composed of a rotor 12 facing the electromagnet 10 and having a magnet 13 magnetized concentrically in the axial direction around the shaft, and a first speed increaser 17 are provided. In addition, an induction generator or a synchronous generator is installed on the first shaft 18b as the first generator 19, and the first system power supply 20 is installed only when the first generator is an induction generator.
Also, below the concentric ring 9 in the wind tunnel, a first power generation device including a programmable controller 14, a controller 15, and a driver 16 connected to the electromagnet 10 is installed.
The second shaft 21a is provided with a second speed increaser 22, and the second shaft 23b is provided with a second induction generator or a second synchronous generator as a second generator 24. Is installed only when the second generator is an induction generator.

(Appropriate air volume and pitch drive mechanism configuration)
The rotor head 7 is at the top of the first shaft 8a, and the rotor head 7 is connected to a wind turbine having six propellers and a pitch drive mechanism (hydraulic system, not shown).
When a wind of 33 m / s is blown from the blower, the wind speed in the vicinity of the propeller 6 is detected by each of the wind speed sensors 5a to 5d, and the data is sent to the computer, and the data and the appropriate wind speed and air volume data obtained in advance. The air flow from each of the four blowers is adjusted by the computer so that the wind speed of the wind speed sensors 5a to 5d is 33 m / s, and the pitch drive mechanism sets the pitch angle of the propeller 6 to an appropriate pitch angle. In other words , the first shaft 8a starts to rotate in the vicinity of the rotation speed (40 rotations / minute for the induction generator, 39.375 rotations / minute for the synchronous generator) 5% faster than the rotation of the excitation circuit.

(Configuration of the first shaft 8a)
A propeller 6 and a pitch drive mechanism are attached to the rotor head 7 of the first shaft 8a, and a hybrid type excitation circuit is installed on the first shaft 8a between the rotor head 7 and the first speed increaser 17 for excitation. A first speed increaser 17 is installed on the lee side of the circuit.

(Description of hybrid excitation circuit configuration and operating conditions)
FIG. 2 is a cross-sectional view of a five-phase excitation circuit installed between the rotor head and the gearbox. The frequency of the input pulse is 1300 Hz for an induction generator, 1250 Hz for a synchronous generator, When a current flows through the controller 15 at a step angle = 0.72 °, a pulse signal is given to the driver 16, and the driver 16 switches the current of the electromagnet 10 1,300 times or 1,250 times per second. The switching of the magnetic poles of the electromagnet is also performed 1,300 times or 1,250 times.
The first shaft 8a, which uses the rotational force of the propeller 6 as a drive source, has an appropriate air volume and an appropriate pitch angle in the vicinity of 40 rpm for an induction generator and 39.375 rpm for a synchronous generator. When the magnetic pole of the electromagnet 10 is switched, the magnet 13 reacts to the magnetic pole of the electromagnet 10 every step angle, so that the first shaft 8a decreases the rotation speed and the rotation speed is rotated by the excitation circuit. The speed is the same as that of the excitation circuit while adjusting the speed at 1,300 times or 1,250 times per second with the same speed as the excitation circuit (in the case of an induction generator, the speed is 38 rpm). , Rotating at a rotational speed of 37.5 rpm.
The difference between the rotation speed of the first shaft 8a that uses the rotational force of the propeller 6 as a driving source and the rotation speed of the excitation circuit is almost a slight difference in most cases, and the difference in the rotation speed due to changes in wind speed is sudden. Even if the rotation of the first shaft 8a is slower than the rotation of the excitation circuit, it is set 5% earlier, so an additional magnetic force is required only when it is 5% or more. Since the adjustment is performed by one step angle, and after the adjustment, the appropriate air volume and the appropriate pitch angle are obtained, the rotation speed error does not accumulate, and the error caused by switching 78,000 times or 75,000 times per minute is 0. It is less than 72 °, and a large magnetic force is not required for the adjustment.
If a delay of 7% occurs, the rotation of the first shaft 8a is 2% (0.0144 °) per step angle slower than the rotation of the excitation circuit, so that torque is generated and the rotation is corrected by 2%. For this reason, the magnetic force of the electromagnet 10 is required, but since there is also an inertial force in the rotation direction, the adjustment is of a level that boosts the rotation and does not require a large magnetic force.
On the other hand, when it is early, a deterrence of speed adjustment of 12% (0.0864 °) or more per step angle is necessary, but it is sufficient when setting the number of windings of the electromagnet that determines the magnetic force of the electromagnet 10. It corresponds so that power can be obtained.

(Configuration of planetary gear)
The gear ratio between the planetary gear on the input side and the sun gear on the output side is set to increase the sun gear 40 times,
When the generator is an induction generator, the rotation speed of the first shaft 8a is 38 times / minute, the rotation speed of the first shaft 18b is 1520 rotations / minute, and when the generator is a synchronous generator, the rotation speed is The number 37.5 revolutions / minute is increased by 40 times to 1500 revolutions / minute.

(Description of the configuration of the first generator 19 and the first system power supply 20 and the operation status)
The first generator 19 is provided leeward of the first speed increaser 17 on the first shaft 18b, and the first system power supply 20 is installed only when the generator is an induction generator.
When the first generator 19 is an induction generator, the rotation speed of the first shaft 8a is 1520 rotations / minute which is 1.3% faster than the synchronous rotation speed (1500 rotations / minute) of the generator in the first speed increaser 17. Is transmitted to the first shaft 18b, and together with the first system power supply 20, the induction generator generates electricity.
When the first generator 19 is a synchronous generator, the rotation speed of the first shaft 8a is increased by the first gearbox 17 to 1500 rotations / minute of the synchronous rotation speed of the generator and transmitted to the first shaft 18b. The synchronous generator 19 generates power.
Since the rotation speed of the first shaft 18b is reliably 1500 rotations / minute, it is possible to rotate at a rotation speed corresponding to a preset magnetic pole in advance, and converters and inverters for minimizing output fluctuations Installation is no longer necessary.

(Description of the configuration of the second power generation device and the operation status)
The second shaft 21a has the same axis as the first shaft 18b, and a second speed increaser 22 composed of a planetary gear with a double speed increase rate is installed leeward of the second shaft 21a.
A second generator 24 having two magnetic poles is provided on the second shaft 23b leeward of the second speed increaser 22, and the second system power source 25 is used only when the generator is an induction generator. Installed.
In the case of an induction generator, the second shaft 21a is inherited by 1520 rotations / minute, and in the case of a synchronous generator, rotations of 1500 rotations / minute are taken over.
The number of revolutions is doubled by the second speed increaser 22 to 3040 revolutions / minute or 3000 revolutions / minute, respectively. However, since the number of magnetic poles is two, the first power generation apparatus and the second power generation apparatus The amount of power generated is the same.

(Explanation of providing the first power generator and the second power generator on each side of the N-shaped wind tunnel)
FIG. 3 shows a case where one side of a pentagonal wind tunnel body having N of 5 is a wind tunnel body, and 10 power generation devices of the first power generation device and the second power generation device are provided on each side at five locations. It is a conceptual diagram.
Each first power generation device provided on each side of the pentagon is an independent power generation device. The power source is a commercial power source. The wind blown from the blower is discharged from the discharge port 2 to the outside of the wind tunnel body and circulated. do not do.

C. The sum of (31) and (32) is input as the total demand (33) actually generated.
2. If the total demand (33) is the same or larger than the generator output at the wind speed of 33 m / s and smaller than the generator output at the wind speed of 34 m / s, the generator output at the wind speed of 34 m / s is 1 m faster than the current wind speed. An instruction to generate power by changing is issued, and it is confirmed that the change is surely made by the generator output measuring instrument.

An instruction to generate power is issued, and it is confirmed that the change is surely made by the generator output measuring instrument.

(Other embodiments)
In this description, the rank category of the total demand (33) that actually occurs is set to increase every 1 m of wind speed. However, the rank category may be set to increase every 0.5 m of wind speed.

[Effect of the embodiment]
In the present invention, rank classification of the actual demand amount (33) actually generated is performed, and when the total demand amount (33) increases to become a demand amount that needs to be changed in rank classification, it is changed to a wind speed that can be supplied, Since the generator output is increased, the most efficient supply system is established.
For example, the power demand per day at department stores differs greatly between the day after opening and the night after closing, and the power demand per year also varies greatly between spring, summer, autumn and winter. It has the advantage of being able to respond to changes in power demand with certainty, making it ideal as a distributed power source for combating global warming installed in urban buildings.
