Thereby, it is possible to efficiently and automatically set whether it is more advantageous in terms of power generation to place the main body in wind power generation or solar power generation.

It is desirable that the control unit periodically obtains the direction of higher power generation between wind power generation and solar power generation and controls the movable mechanism so that the rotor blades are directed in the determined direction.
As a result, depending on the changing weather conditions, wind direction, and wind speed, it is automatically set whether it is advantageous to place the main body in wind power generation or solar power generation in terms of power generation, and high efficiency power generation It can be performed.

In addition, this hybrid power generator

Hereinafter, embodiments will be described with reference to the drawings.
The hybrid power generation apparatus 1 according to the embodiment generates power by wind power generation and solar power generation, and uses the generated power in a home. However, it can be used not only for home use but also as a commercial power generator 1.

  As shown in FIGS. 3, 4, and 5, the hybrid power generation apparatus 1 according to the embodiment is installed adjacent to a house that uses generated power (FIGS. 3 and 4), a roof of a house, a veranda, or the like. It is installed in a building (FIG. 5), and is configured so that power can be supplied to the electrical equipment in the house or sold to an electric power company by switching the switching device 81. In this hybrid power generation apparatus 1, a rotor blade 3 having a plurality of blades 31 is installed at the upper end of a pole 2. All blades 31 provided in the rotor blades 3 are provided with solar panels 51. Wind power generation is performed by rotating the rotor blades 3 by receiving wind (FIG. 4), and the solar panels 51 provided on the blades 31 are provided. Solar power generation is performed by receiving sunlight (FIGS. 3 and 5).

  As shown in FIGS. 1 and 2, the hybrid power generation apparatus 1 includes a solar power generation unit 4 that generates wind power by rotating a rotating blade 3 and a solar panel 51 that is provided on a blade 31 of the rotating blade 3. And a power generation unit 5. The wind power generation unit 4 is configured by a rotary generator 42 provided in a rotor unit 41 that rotatably supports the rotary blade 3, and the rotary generator 42 generates power by the rotational force of the rotary blade 3. In the solar power generation unit 5, the solar panel 51 substantially plays the role, and the solar panel 51 outputs electricity when receiving sunlight. As the solar panel 51, various types such as a polycrystalline silicon type power generation element, a single crystal silicon type power generation element, and a thin film type power generation element can be used.

  Each blade 31 of the rotary blade 3 is formed by a transparent hollow body 32 made of transparent plastic, and the solar panel 51 is disposed in the transparent hollow body 32 with the light receiving surface facing the front side of the rotary blade 3. . Thereby, the solar panel 51 is not exposed to the outside and protected from wind and rain. Further, since the solar panel 51 is directed to the front side of the rotary blade 3, solar power generation can be efficiently performed when the rotary blade 3 is directed to the sun. The electric power generated by the rotary generator 42 of the wind power generation unit 4 is stored in the power storage unit 8 through the wiring 43, and the power generated by the solar panel 51 of the solar power generation unit 5 is stored in the power storage unit through the wiring 53. 8 is stored.

  The hybrid power generation apparatus 1 includes a movable mechanism 6 that moves the rotor blade 3 in all directions of the upper hemisphere. The movable mechanism 6 is provided on the pole 2, and a lateral rotation mechanism 61 that rotates the rotary blade 3 around the pole 2 in the horizontal direction by 360 °, and the rotary blade 3 from a position where the rotary blade 3 faces the horizontal direction. And a vertical rotation mechanism 62 that rotates 180 degrees and rotates it 180 °. The movable mechanism 6 can turn the rotor blade 3 in a predetermined direction in all directions of the upper hemisphere.

  The hybrid power generator 1 includes an anemometer 71 that measures the wind speed and a light meter 72 that measures the amount of sunlight. The anemometer 71 and the light quantity meter 72 are attached to the top of the rotor portion 41. The anemometer 71 measures wind speed values in all directions in the 360 ° range around the pole 2. The light quantity value of sunlight at all angles in the 180 ° range is measured by the light quantity meter 72 from the horizontal direction upward.

  The hybrid power generation apparatus 1 includes a control unit 7 that controls the movable mechanism 6 based on the measurement values of the anemometer 71 and the luminometer 72. That is, the control unit 7 compares the wind power generation amount by the wind power generation unit 4 with the solar power generation amount by the solar power generation unit 5 in the omnidirectional direction of the upper hemisphere, The movable mechanism 6 is controlled so that the rotary blade 3 is directed in the direction in which the power generation amount is the highest. The power of the power storage unit 8 is used as the power source for the movable mechanism 6 and the control unit 7.

  As the wind power generation amount by the wind power generation unit 4 here, a predicted wind power generation amount per hour obtained from the wind power generation capacity of the installed rotor blade 3 based on the wind speed value measured by the anemometer 71 is used. The predicted amount of wind power generation is determined for each of the eight directions, for example, east, west, south, north, and southeast, southwest, northwest, and northeast of the 360 ° range around the pole 2.

  In addition, the solar power generation amount by the solar power generation unit 5 here is a predicted value of solar power generation per hour obtained from the solar power generation capability of the installed solar panel 51 based on the light amount value of sunlight measured by the light meter 72. Is used. The predicted amount of solar power generation is obtained for each of seven angles, for example, for each angle increased from 0 ° to 30 ° in the 180 ° range from the horizontal direction on the south side to the horizontal direction on the north side. Note that the predicted amount of solar power generation is performed only during the time when the sun is rising from sunrise to sunset. That is, at night, the hybrid power generator 1 is used for wind power generation.

  And the control part 7 calculates | requires the direction in which the electric power generation amount is higher among wind power generation and solar power generation regularly, for example every two hours, and it is a movable mechanism so that the rotor 3 may be pointed in the calculated | required direction. 6 is controlled. For example, when the amount of wind power generated by wind in the east direction is higher than the amount of solar power generated at any angle, the movable mechanism 6 is controlled so that the rotor 3 is in a horizontal posture and faces east. Then, the hybrid power generation apparatus 1 generates power with a main body in wind power generation in terms of power generation. At this time, when the solar panel 51 installed on the blade 31 of the rotary blade 3 receives sunlight, naturally, solar power generation is also simultaneously performed. On the other hand, when the solar power generation amount at the 30 ° position in the south direction is higher than the wind power generation amount in any direction, the movable mechanism 6 is controlled so that the rotary blade 3 faces the 30 ° position in the south direction. At this time, if the rotor blades 3 receive the south wind and rotate, naturally wind power generation is also performed at the same time.

  As described above, according to the hybrid power generator 1 according to the present embodiment, either the wind power generation or the solar power generation is generated in accordance with the weather condition, the wind direction, and the wind speed that change every moment as the direction in which the rotor blades 3 are directed. It is automatically set whether it is more advantageous to place the subject in Therefore, in hybrid power generation that mutually uses wind power generation and solar power generation, highly efficient power generation can be performed according to weather conditions, wind direction, and wind speed.
