Description

The present invention relates to a solar power generation / wind power generation hybrid power generation apparatus.

The present invention is a solar power generation / wind power generation hybrid power generation apparatus, which is a highly efficient, safe and secure power generation apparatus using pure environmental natural energy of wind power and sunlight.
1. New power generation system with power generation output of 0.1 kW to 10 kW or more in a small and small space (within 2 m in length x within 2 m in width x within 3 m in height) that was impossible with conventional wind power generation Specifically, it is a solar power generation / wind power generation hybrid power generation apparatus that incorporates magnetic levitation rotation that has not been demonstrated in Japan and overseas.
2. As a feasibility, solar power generation can be seamlessly integrated into wind power generation, contributing to society in the local smart grid concept.
3. For example, if it is connected to the home after installing it in a general household, power can be sold for 24 hours, which was impossible in the past, and the economic cost burden on consumers is greatly reduced, making it attractive without CO2 emission. Device.

1. In the case of large-scale wind power generation, the wind conditions at the location where the wind power generator is installed greatly affects the profitability of the power generation, and the output voltage and power factor fluctuate greatly regardless of demand as the wind speed fluctuates. .
Moreover, it is said that the wind speed of the wind to the blade | wing (blade) of the conventional wind power generator needs 6 m / s or more by an annual average wind speed. For this reason, the blades are not moving at all times, and the time when they are actually stopped is so much that it is regarded as a problem.
On the other hand, if the blade rotates, noise damage or the like is generated in the surroundings. The sound coming out of the entire disk with rotating blades with a diameter of 60m or more is 100dB when the wind speed is 8m / s at a distance of 10m.
This is almost the same noise as under the guard that the train passes.
(Near airplane engine: 120 dB, car warning: 110 dB, under train guard: 100 dB, loud solo: 90 dB, subway car: 80 dB, vacuum cleaner: 70 dB, normal conversation: 60 dB, quiet office: 50 dB Library: 40 dB, whispering voice: 30 dB, touching sound of leaves: 20 dB)
The installation is too expensive at the moment, so legal subsidies are often required in terms of cost. In addition, expensive additional costs are required for system expansion.
In addition, birds (birds migrating) bird strikes, etc. on the blades (blades), damage to the blades (blades), etc., even though lightning strikes, etc., cause malfunctions and accidents The wind turbines tend to be taller year by year, and the blades tend to be longer. The maintenance costs for inspection and repair are increasing accordingly. Increasing the height of the tower by 10% increases the power of about 6% annual power generation (calculated as windshare 1/5: 1.1 ^ (3/5) = 1.06), but not just the price of the tower, Prices will increase (transportation costs, construction costs, maintenance costs, aviation law measures, etc.) (also a weakness of hugeness).
The scenery is so intimidating that it is so huge that some people feel fearful and creepy. It is often located on the coast, plateau, mountains, etc., and it has been pointed out that tourists may decrease.
In addition, since power transmission lines are required, power generation stops frequently due to damage to power transmission lines due to earthquakes.
Most of the products are made by ship and are transported by ship and transport from the port is also difficult. Road maintenance through large trailers is also a necessary condition, so it is impossible to install a general household.
2. In the case of small wind power generation, there are two domestic production companies, but there are products installed at home with a maximum power output of 5 kW, which requires a wind speed of 20 m / s, This wind speed is high enough to make a standing tree fall down like a typhoon. (Wind speed of 10m / s makes it difficult for people to walk toward the wind)
The small wind power generators of the two companies are designed with a wind speed of 12.5 m / s as a reference, and the output at this reference wind speed is about 2.5 kW. This wind speed should continue every day, but if it continues, it is not in an environment where humans can live.
The average annual wind speed in Japan is about 3 m / s, so even if it is calculated from now on, the power generation output is 0.5 kw or less at the most. Therefore, considering the cost of installing the product, it is better to buy power from the power company. It is.
In reality, noise problems are also serious and there are many troubles in the neighborhood.
3. In the case of solar panel (solar cell) power generation Considering the panel installation area and power generation efficiency (profitability), it is a product with a very high panel cost because it generates electricity only during the day and not at night. As is well known, the amount of power generated in the event of problems, garbage, yellow sand, sunshine hours, sunshine conditions, cloudiness, rain, etc. is very small, and the installation area is good, so the installation idea on the roof is good. Conditions such as the direction and direction of the roof are imposed. The weak point is that the total weight is heavy.
If snow accumulates or adheres to dust, it must be removed from the surface of the solar panel installed on the roof, which is very dangerous for climbing the roof. There are a large number of people who have died after being taken down or injured (removal is also required for solar panels installed in the field).
In addition, the solar panel installed on the roof weighs about 0.5 tons (including a 500kg stand), a burden on the building, and a seismic structure problem. (Snow country also adds snow weight)
Of course, the roofs are damaged quickly, the frequency of paint and tile replacement maintenance increases, and there are many residents who are suffering from dung and crying complaints, such as sparrows and birds.
And the biggest problem is that the ratio of return on investment is extremely bad because it cannot be used at night, and even if a large windmill (2000 kW) and a solar cell are compared, the power generation amount of the solar cell is 4 to 5 kW at the maximum for one house. is there. If the same output as a large-scale wind power generator is drawn out, about 400 to 500 houses are required.

Patent application number 2009-214797, publication number 2011-64110, invention name: Wind power generator, which combines wind power and solar panel, has been filed, but the solar panel is pasted on the blade (blade) part that received wind According to the present invention, the present invention provides solar panel power generation on the surface of the columnar body, and floats and rotates the columnar body by the repulsive force and the attractive force of the magnetic force.
Furthermore, a mirror medium is installed on the rear surface of the columnar body, and the position and direction of the sun is tracked and tracked with a special sensor, and the mirror medium moves to the rear part where it is not exposed to direct sunlight. There is a reflection control medium inside, and the entire columnar body is irradiated with light.
In addition, there is a device that just combines a solar panel and a small wind power generator (wind-bird-like) into a single pole, but the wind-light wind power is very small and has a very low power generation capacity of 0.3 kW.
The present invention has no products existing in the prior art.

JP2011-64110A

It is a device that overcomes each other's weaknesses by combining solar panel power generation and wind power generation, and makes use of the strengths of both parties to make the most of 24-hour power generation with a new technology that can generate electricity for 24 hours. You can also.
Although there is a device that combines a solar panel and a small wind power generator (wind-bird-like) on a single pole, the output power is poor and the cost is increased instead of the lack, which increases the burden on consumers ( (The solar power must be provided with a converter for the power source for direct current and the wind power for AC respectively.) This device also integrates a power source exchanger and holds a convert power circuit unit.

The present invention is a power generation device that is less susceptible to the weather regardless of day or night.
1. It is an invention that can rotate at a slight wind speed (1 m / s to 2 m / s) and takes into account resistance such as gravity and friction.
2. During the day, solar panel power generation and wind power generation were carried out at the same time. Even when direct sunlight was weak due to sunshine hours or rain, it was compensated with wind power, and at night it was generated by wind power generation. In this case, the electricity stored in the storage battery can always be used at home for 24 hours, the power can be stably supplied to the grid connection for 24 hours, and the invention can participate in the smart community grid for the region. is there.

The present invention magnetically levitates a columnar generator using magnetic repulsive force and attractive force to reduce frictional resistance of a rotating shaft and solve noise.
1. The noise is 50dB or less (quiet office), and 10kW power generation is possible.
2. Applying magnetic circuit technology to make the magnetic flux density and magnetic characteristics uniform, fan-shaped magnets are arranged in a donut shape.

The present invention facilitates the use space, the price, the small space, the ease of maintenance, and the introduction in a general household.
1. Less installation area and use space, workability (construction), work (construction) cost, safety, no high work such as roofs, good workability, extreme risk of bird strike The power generator has a structure that is easy to maintain and that does not need to worry about a decrease in power generation due to dust, yellow sand, and snow.
2. Compact structure (less than 2m in length x less than 2m in width x less than 3m in height) has succeeded in reducing the space. Despite being compact, it can output more than 10kw and can be easily installed in ordinary homes. That's it.

When the present invention is enlarged and compared with a large windmill with a power generation output of 2,000 kw, the apparatus of the present invention can generate electricity sufficiently if it is 5 m long, 5 m wide, and 5 m high.
However, if the power generation output is increased, it is affected by electromagnetic waves and cannot be recommended for general household use. Therefore, the product of the present invention is intentionally compact to suppress the power generation output to 10 kw.
This made it possible to install a general home.

Hereinafter, a preferred embodiment of the present invention is a solar power generation / wind power generation hybrid power generation device, in which a solar panel power generation unit is provided on a surface of a columnar body, and a magnetic application power generation unit of the wind power generation unit is integrated with the columnar body. By assimilating the solar panel power generation and magnetic application generator integrated with the columnar body, the weight and gravity are reduced, and the power is generated by rotating it even in a slight wind.
In addition, a mirror medium is installed behind the pillar-shaped solar panel generator and the magnetic application generator so that the center of the sun is always detected by a special sensor, and the mirror medium tracks and follows the azimuth of the sun (east to west). The mirror medium reflects the part where the columnar body is not exposed to sunlight (shadow side), and the sunlight is favorably reflected in the mirror medium, that is, the incident angle and reflection angle of sunlight. The reflection control medium is controlled by a microcomputer so that light is suitably applied to the entire columnar body.
The columnar body has blades that hit the wind, and the wind that hits the blades also captures changes in air pressure and airflow (aircraft wing curves) into the gantry frame, and uses the changes in air pressure and airflow to make the columnar body This improves the rotational force.
Therefore, in a small space of 2 meters in height and 3 meters in height, 16 kW can be output at a wind speed of 5 m / s.

The present invention is a hybrid power generation device in which solar panel power generation and wind power generation are integrated, and is a combined power generation device that incorporates a magnetic application generator into a columnar body and rotates it with wind power to simultaneously perform solar panel power generation and wind power generation. is there.
1. The shape is a columnar body (a variety of products such as 3, 4, 5, 6, 8 octagonal columns, cylinders, etc.), and it is rotated by wind power. Magnetic applied generators are provided on the upper and lower surfaces of the rotated columnar body.
It holds a power supply that simultaneously converts the output energy direct current from the solar panel power generation and the alternating current from the magnetic applied generator, and the alternating current from the magnetic applied generator generated from the DC power and rotational force from the solar panel power generation of the columnar body. Electric power is taken out at the same time.
2. The method for extracting power from solar panel power generation is a non-contact extraction and supply to a power supply circuit.
3. The magnetic applied generator can be installed inside or outside the rotating columnar solar panel.

The present invention magnetically levitates solar panel power generation and wind power generation in the form of a columnar body, thereby reducing the influence of its own weight and rotating it even in light winds. Magnetic levitation is performed using the repulsive force and attractive force of the magnet, and the columnar frame is designed in consideration of the wind fluid. For example, airplane wings also fly due to fluid and air pressure changes on the top and bottom surfaces of the wings. The product of the present invention is a special structure in consideration of the fluid and air pressure, and further improves the rotational driving force of the columnar solar panel.

In the present invention, a sun tracking tracking mirror medium is installed at the rear part of the rear surface of the columnar body, and a special sensor captures the position movement of the sun (from east to west), and the mirror medium itself tracks and tracks, so that sunlight is best. In this state, a special mechanism that reflects light is held, and the special technology is controlled by a microcomputer to always capture the center of the sun.

In the present invention, a reflection control medium is provided in a mirror medium provided behind a columnar body, and the incident angle and the reflection angle of the light are controlled by the microcomputer in a timely and suitable manner to reflect the light to the columnar body. To make it happen.

In the present invention, measures such as snow, dust, and flying yellow dust are the pillar body and rotate, so that the dewatering function is automatically activated even if it is left working.

The present invention is very compact with a length of 2 m or less, a width of 2 m or less, and a height of 3 m or less, and can generate a power generation of 10 kW or more, and the price range is scheduled to be within 2.5 million to 3 million yen. (Conventional solar panels are expensive at around 5 million yen with 5kW power generation, and you can't sell electricity at night.

In the present invention, the maximum power point changes because the output conditions change for each solar panel. Therefore, we have developed a maximum power point tracker (MPPT).
This is a method of connecting and controlling a step-up MPPT with each solar panel in multiple systems and is an independent connection method used in parallel connection.
As shown in Figure 5, there is no connection between solar panels, unlike single system connection.

Magnetic levitation of a rotating body, magnetic circuit design technology development 1, magnetic circuit design, disk type (doughnut type) magnets can be magnetized with different polarities on the front and back, but due to magnetic properties, the disk type is Since the magnetic flux density and magnetomotive force partially change, fan-shaped magnets are arranged on a disk to reduce the change in characteristics so that the magnetic flux density and magnetomotive force do not change, so that the amount of repulsive magnetic force is uniform. The columnar body is floated and rotated.
2. The fact that magnetic characteristics change due to temperature change has been elucidated in the prior art, and if the magnetic characteristics change, the magnetic levitation balance of the rotating body will be disrupted, so to cope with the change, A magnetic circuit design is provided in which the top surface of the rotating body is provided with magnetism for attraction, and magnetic levitation is controlled under the best conditions by the repulsive force from below and the attraction force from above.
