[0002]

2. Description of the Related Art A wind power generation system is a non-polluting power generation system using natural energy called wind power, and its utility value is considered to be high.

As is well known, a conventional wind power generation system uses a windmill as a power source of a generator.

[0004]

The output of a windmill is proportional to the cube of the wind speed and proportional to the square of the blade diameter. For this reason, it is desirable to install a windmill high above the ground so that it can receive a strong wind. However, since the fluctuation range of the wind intensity is large, if the wind turbine is installed high above the ground, the mechanism for supporting the blades will require extremely large mechanical strength, and the equipment cost will be large, and large power generation equipment will be required. Construction is practically difficult. For this reason, at present, the output per windmill can be as small as about 50 kW to 100 kW.

[0005] Further, the utilization efficiency of wind energy per windmill is only about 30%.

Further, in order to secure safety and to secure sufficient wind energy, it is necessary to increase the interval between adjacent wind turbines to some extent, which requires a vast site.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of a conventional wind power generation system using a windmill.
An object of the present invention is to provide a new wind power generation system that facilitates construction of a large-scale power generation facility, improves wind energy use efficiency, and can be installed on a relatively small site.

Further, providing a plurality of wind receivers at appropriate intervals on the annular traveling body increases wind energy directly connected to traveling of the traveling body, thereby increasing traveling speed of the traveling body. It is desirable in order to increase the induced power.

Further, it is desirable to control the attitude of the wind receiving portion in accordance with the wind force and the wind direction in order to increase wind energy directly connected to the traveling of the traveling body, and consequently to increase induced power.

Here, specifically, the traveling body has a magnetic field generating section, and the traveling path is a conductor that generates an induced power by interlinking with the magnetic field lines of the magnetic field generating section when the traveling body is traveling. Having a part.

The magnetic field generating section is constituted by a permanent magnet or a superconducting coil, and the conductor section is constituted by a pair of metal walls vertically disposed on both sides of the permanent magnet or the superconducting coil. When traveling, the permanent magnet or the superconducting coil is configured to pass between the pair of metal walls.

FIG. 1 is a conceptual diagram of a wind power generation system according to an embodiment of the present invention.

In FIG. 1, a wind power generation system includes a traveling body 1 that travels by receiving wind power and a traveling path 2 through which the traveling body 1 passes.
, And is configured to generate induced electric power by the traveling of the traveling body 1.

The traveling body 1 is shown as a single body in FIG. 1, but when the traveling path 2 is an annular traveling path 2 as shown in FIG. 1, the traveling body 1 is an annularly coupled traveling body 1 as shown in FIG. The configuration is desirable in order to increase the induced power due to an increase in the location where the induced power is generated.
Here, the annular connecting traveling body 1 is of a caterpillar type or a chain type, and is a flexible continuous body that can travel on the annular traveling path 2.

The traveling body 1 includes a support portion 11, a wind receiving portion 12 provided on an upper portion 11c of the support portion 11, and a magnetic field generating portion 13 provided on a lower portion of the support portion 11.

When the running body 1 is an annularly connected running body 1, the supporting portion 11 is formed by connecting a large number of supporting plate pieces 11a, as shown in FIG. It is connected by a connecting member 11b so that it can be bent.

When the traveling body 1 is an annularly connected traveling body 1, a plurality of upper portions 11c of the supporting portion 11 are provided at appropriate intervals as shown in FIG. Is desirable for increasing the thrust of the traveling body 1.

The wind receiver 12 is like a sail of a yacht or a wing of an aircraft. The attitude of the wind receiving unit 12 can be changed by a control device (not shown).
It is desirable to always keep the wind power received by 2 and generate a constant induced power. Here, the attitude of the wind receiving portion 12 can be remotely controlled by radio waves from a control room installed in a central zone surrounded by the annular traveling path.

The magnetic field generator 13 is constituted by a permanent magnet or a superconducting coil. As shown in FIG. 2, the magnetic field generator 13 generates a magnetic field B perpendicular to the traveling direction v of the traveling body 1.
Is to occur. However, when it is necessary to increase the bottom area of the traveling body 1 in order to secure the traveling stability of the traveling body 1, the magnetic field generating unit 13 is also provided on the bottom surface of the traveling body 1 so that the vertical magnetic field B is generated. May be generated,
Thereby, it is possible to simultaneously secure the running stability of the traveling body 1 and increase the induced power.

Running path 2 The running path 2 is for generating induced electric power by the running of the running body 1. Although the traveling path 2 may be a terminal road, FIG.
3 and the annular traveling path 2 as shown in FIG. 3 are preferable from the viewpoint of enabling the traveling body 1 to continuously travel, increasing the induced power, and improving the utilization efficiency of the wind energy.

As shown in FIG. 2, the traveling path 2
When the vehicle travels, there is a conductor portion 21 which generates induced power by interlinking with the magnetic field lines of the magnetic field generating portion 13. The conductor portion 21 includes a pair of metal walls 21A vertically arranged on both sides of the magnetic field generation portion 13,
When the traveling body 1 travels, the magnetic field generator 13 is configured to pass between the pair of metal walls 21A and 21B.

The traveling path 2 is configured so that the traveling body 1 can travel smoothly. For example, traveling path 2
Is a pair of metal walls 21A, as shown in FIG. 4 and FIG.
An annular support structure plate 22a, 22b is formed on each inner surface of 21B, and a sliding member 23 such as a roller or a bearing is provided on the upper and lower surfaces of each annular support structure plate 22a, 22b. It is configured to

In the wind power generation system configured as described above, the traveling body 1 travels on the traveling path 2 when the wind receiving portion 12 receives the wind. While the traveling body 1 is traveling, the magnetic field generating unit 13 passes between the pair of metal walls 21A and 21B, so that each metal wall 21 is formed according to Fleming's right-hand rule.
A and 21B generate induced power. Then, the induced power is supplied to the load 3 electrically connected to the metal walls 21A and 21B.

Here, when the traveling body 1 travels, the traveling body 1 receives a braking force of J × B per unit area from the metal walls 21A and 21B due to the induced current J and the magnetic field B. Is canceled by the wind force, the speed of the traveling body 1 is maintained at a constant speed. Based on such a principle, when the traveling body 1 starts traveling, the load circuit is kept open and the traveling body 1 is controlled so that the braking force does not act on the traveling body 1.
Can be rapidly accelerated, and thereafter, when the thrust of the traveling body 1 comes to balance with the braking force, the load circuit is closed, and thereafter, the attitude of the wind receiving portion 12 is controlled so as to travel at a constant speed. Thus, a constant induced power can be generated.

When there is no wind, the traveling body 1 may be run by electric power supplied from the outside. Output smoothing can be achieved by using such external power driving together.

[0028]

In the novel wind power generation system according to the present invention, the wind receiving portion changes the wind pressure into forward energy almost independently of the wind direction and converts it directly into traveling energy (for example, from the front). Even if it is wind, it can be converted into forward force by controlling the wind receiving portion.) Unlike a windmill, almost 100 wind energy is used.
% Running energy. As a result, when power is generated in the same use area as the wind turbine, the generated power (200 to 300 kW) is three times or more that in the case of the wind turbine.
Since it is easy to increase the use area by 10 times, if the power generation capacity of one wind power generation system is set to 2 to 3 MW, the power generation equipment including ten wind power generation systems is 20 to 30 MW.
W and a function similar to that of small hydroelectric power generation, so that it is possible to easily realize power generation equipment which is considered to be the most necessary. In addition, the present invention has an effect that wind noise caused by a windmill can also be prevented.
