First, the operation of generating AC electricity by the wind power generator 120 and outputting it to the load 118 and charging the storage battery 115 will be described.

When the illuminance of detecting the illuminance of the photovoltaic panel 100 by the photodetector 102 is lower than the illuminance preset in the controller 108, the controller 108 relay coil RY of the switching means 110. Since a control signal, specifically a current, is not output to (), the state in which the movable contact (a) is in contact with the fixed contact (b) and kept closed is maintained as it is, and the movable contact (c) is the fixed contact (d). The non-contact state is maintained as it is.

Accordingly, the windmill body 123 in which the wind vane 123 of the wind power generator 120 supports the wind vane 123 and the windmill 124 in accordance with the wind direction of the wind turbine body 120 via the first bearing 122. A second shaft 127, which is rotated about 121 and engaged with the first bevel gear 126 installed at the proximal end of the first shaft 125 rotatably supporting the windmill 124, has a third bearing.

In the above description, the second spur gear 130 and the third spur gear 132 are engaged with the outer circumferential surface of the first spur gear 129, but the second spur gear with the upper outer circumferential surface of the first spur gear 129. Since the 130 is engaged, and the third spur gear 132 is meshed with the second spur gear 130 so as not to be in contact with the second spur gear 130 under the outer circumferential surface of the first spur gear 129, the windmill main body B may depend on the wind direction. Even if is rotated, the second spur gear 130 and the third spur gear 132 may rotate without interference with each other.

The DC electricity converted by the AC / DC inverter 112 is charged and regulated by the charge controller 114 to be charged to the battery 115 through the fuse F and the main switch 119, and at the same time, the DC / AC inverter 116.

Next, the operation of generating DC electricity by the solar panel 100 using sunlight is described.

The wind speed input to the controller 108 is lower than the wind speed preset in the controller 108, and the illuminance of the solar panel 100 detected by the photodetector 102 is preset in the controller 108. If higher, the solar panel is used to generate DC electricity by the solar panel 100.

When the controller 108 is higher than the preset illuminance, the controller 108 causes a control signal, specifically, a current, to flow through the relay coil RY of the switching means 110, whereby the movable contact of the switching means 110 is performed. (a) is separated from the fixed contact (b), and the movable contact (c) of the switching means (110) is brought into contact with the fixed contact (d).

Accordingly, the DC electricity is generated by the solar panel 100, and the DC electricity generated by the solar panel 100 passes through the movable contact c and the stationary contact d of the switching means 110. It is applied to the charge controller 114, is charged to the storage battery 115 through the fuse (F) and the main switch 119 under the control of the charge controller 114, and at the same time, the AC electricity in the DC / AC inverter 116 The AC electricity converted by the DC / AC inverter 116 is distributed in the AC distribution panel 117 and applied to the AC load 118 to drive a lamp or a driving body which is a load.

In the above description, the specific embodiments have been shown and described, but the present invention is not limited thereto, for example, by those skilled in the art without departing from the concept of the present invention. Of course, the design can be changed in various ways.

As described above, according to the solar / wind combined cycle power generation system and the wind power generator used therein, when the illuminance of the solar panel is higher than the illuminance previously stored in the controller by the photodetector, Operates the switching means to generate DC electricity by the solar panel, and when the wind speed detected by the wind speed detector is higher than the wind speed pre-stored in the controller, the control means of the controller maintains the switching means in a non-operating state.
