1 and 2, the wind and solar power generation system 1 according to the present embodiment includes a frame 100, a base 200, a wind power generation unit 300, a solar power generation unit 400, The power storage unit 500, the base driver 600, the detector 700, the module driver 800, the air guide 900, and the controller 1000 may be included.

More specifically, the frame 100 is where the various components constituting the wind and solar power generation system 1 is installed. The frame 100 is disposed at a predetermined position where wind power and solar power generation can be made. The frame 100 may be configured to be movable by a moving means.

The base 200 is rotatably installed with respect to the frame 100. For example, the base 200 may be formed in a disc shape and rotatably installed on an upper surface of the base 200.

The wind turbine 300 is generated by wind and is installed on the base 200. The wind turbine 300 may include at least a blade 310 and a generator 320 for producing power by wind. Since the blade 310 and the generator 320 constituting the wind turbine 300 are already well known, detailed description thereof will be omitted.

Substantially the photovoltaic unit 400, in a state installed on the base 200, will be located above the wind turbine 300. The photovoltaic unit 400 includes a photovoltaic module 410 for producing power by sunlight. The photovoltaic module 410 constituting the photovoltaic unit 400 is also well known and will not be described in detail.

Next, the power storage unit 500 is a place where the power generated by the wind power generation unit 300 and the solar power generation unit 400 is stored. As the power storage unit 500, an energy storage device such as a battery that is well known may be used.

The base driver 600 rotates the base 200 about an axis in a vertical direction with respect to the frame 100. The base driving unit 600 may include, for example, a rotating shaft serving as a rotation center of the base 200, a driving motor providing a driving force for the rotation of the base 200, and a rotational force of the driving motor. It may include a driving force transmission member for transmitting to the 200.

The detector 700 detects a wind direction, a wind speed, a sun position, and a temperature of the solar module 410. Here, 'wind direction' and 'wind speed' are variables related to wind power generation in the wind turbine 300, and 'location of the sun' and 'temperature of the solar module 410' are the solar power generation. The variable 400 is related to photovoltaic power generation. In addition, the detector 700 may further detect noise generated in the power generation process in the wind turbine 300.

In more detail, the wind turbine 300, since the mechanical energy of the blade 310 that rotates substantially by the kinetic energy of the wind is converted into electrical energy by the generator 320, the blade 310 ) Must be arranged in a direction facing the wind to increase the power generation efficiency of the wind turbine 300. In addition, since the kinetic energy of the blade 310 is proportional to the speed of the wind, it is possible to calculate the amount of power generated by the wind turbine 300 according to the detected wind volume. Of course, at this time, the efficiency according to the shape of the blade 310 and the type of the generator 320 will also be considered. And since the solar power generation unit 400 converts light energy of the sun into electrical energy, the solar power generation unit 400 may increase the power generation efficiency of the solar power generation unit 400 by being disposed toward the sun. have. On the other hand, the solar module 410, when the temperature is increased above a predetermined temperature, its efficiency is reduced. In general, when the temperature of the photovoltaic module 410 is increased to more than 25 ℃, depending on the type of the photovoltaic module 410 is slightly different, the power generation efficiency is reduced by approximately 0.45%. Therefore, when the efficiency decrease according to the temperature of the photovoltaic module 410 sensed with respect to the designed power generation output of the photovoltaic module 410 is reflected, the power generation amount of the photovoltaic module 410 may be calculated.

In addition, the module driver 800 rotates the solar module 410 with respect to the base 200 about an axis in a horizontal direction. The air guide unit 900 guides at least a portion of the wind flowing toward the blade 310 to cool the solar module 410. In other words, at least a portion of the wind flowing by the air guide unit 900 for power generation in the wind turbine 300 is used for cooling the solar module 410. Although not specifically illustrated in FIG. 1, the module driving unit 800 and the air guide unit 900 may be applied in the form of a general driving motor or a damper.

In other words, the control unit 1000, in consideration of the detection value of the sensing unit 700, the sum of the amount of power generated in the wind power generation unit 300 and the photovoltaic unit 400, that is, the power finally The position of the base 200 is controlled to maximize the amount of power stored in the storage 500.

In addition, the controller 1000 is guided by the air guide 900 to the air to the solar module 410, the reduction of the amount of power generated in the wind turbine 300 and the solar module ( In consideration of the increase in the amount of power generated in the solar power generation unit 400 according to the temperature decrease of 410, the sum of the amount of power generated in the wind power generation unit 300 and the solar power generation unit 400 is the maximum. The operation of the air guide unit 900 is controlled. In other words, the controller 1000 consumes a part of the wind for generating power in the wind power generator 300 to cool the solar module 410, but the wind power generator 300 and the solar light When the sum of the amount of power generated by the power generation unit 400 is larger, the wind flowing toward the blade 310 is used for cooling the solar module 410.

The operation of the base driver 600 is controlled. On the other hand, the control unit 1000, in the second time zone preset to the rest of the day except the first time zone, the wind direction, wind speed, the position of the sun and the position of the solar module 410 detected by the detection unit 700 The base 200 may be positioned at a position at which a noise detected by the sensing unit 700 becomes less than or equal to a preset value regardless of the sum of the amounts of power generated by the wind power generation unit 300 and the solar power generation unit 400 according to a temperature. ) Controls the operation of the base driver 600. In other words, the controller 1000 is a first time zone in which the noise of the wind turbine 300, substantially the noise generated during the rotation of the blade 310 or the operation of the generator 300 is allowed. For example, even if some noise occurs in the wind turbine 300, the controller controls the wind turbine 300 to reduce the amount of power generated by the wind turbine 300 only to a predetermined level. However, the control unit 1000, even in the second time period in which the noise of the wind turbine 300 is limited, even if the amount of power generated by the wind turbine 300 is excessively reduced, the wind turbine 300 To minimize the occurrence of noise.

For example, in the first time period set from 9:00 am to 6:00 pm, the controller 1000 reduces the sum of the sum of the amounts of power generated by the wind power generator 300 and the solar power generator 400 by 10%. The base driving unit 600 may be controlled so that the base 200 is positioned at a position where the noise detected by the sensing unit 700 is minimized to the following range. In the second time zone set from 6 pm to 9 am of the next day, the controller 1000 does not consider a decrease in the amount of power generated by the wind power generator 300 and the solar power generator 400. The operation of the base driver 600 may be controlled such that the base 200 is positioned at a position at which the noise detected by the detector 700 is equal to or less than a preset value. In this case, the control unit 1000 may control by setting the noise value differently according to the place where the wind power and the photovoltaic power generation system 1 are installed.
