【0015】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a characteristic that it starts a power generation by amplifying an air volume from a low wind speed and operates up to a high wind speed. This is a wind power generator with high power generation efficiency, equipped with a mechanism for obtaining the optimum wind speed for the wind turbine. This will increase the capacity factor, lower the power generation cost and increase the economic effect. It is possible to manufacture from small to large, and it is fortunate that such features will increase the number of candidate sites where wind power plants can be constructed, and will contribute to the spread of wind power generation. [0002] A guide plate fixed vertically or vertically around a vertical axis wind turbine such as a Savonius wind turbine is provided.
There was an idea to collect the low wind speed and increase the speed of the wind hitting the windmill even a little (reference book title Small windmill handbook, published by Power Corporation 298
page). [0003] In a wind power generator,
Rather than unilaterally increasing the air volume, the system has the characteristic of starting the power generation at the lowest possible wind speed and operating at the highest possible wind speed. Another object of the present invention is to realize a wind power generator with high power generation efficiency. This will increase the capacity factor, lower the power generation cost and increase the economic effect. The present invention is to solve the above problems by installing guide disks above and below a windmill. According to the present invention, a wind turbine rotating about a tower is sandwiched above and below by an induction disk having a supporting fulcrum on the tower, the induction disk is connected by a hydraulic cylinder, and a wind vane is connected to the wind turbine. Equipped with a control device with a built-in microcomputer that controls the signal of the anemometer and the amount of expansion and contraction of the hydraulic cylinder, and a mechanism to control the wind direction in all horizontal directions of the windmill, control opening and closing, and obtain the optimum airflow for the windmill It is a wind power generator with high power generation efficiency. In the above, a predetermined wind speed is set in advance in the control device, and when the wind direction and the wind speed change during operation of the wind turbine, the control device calculates the amount of expansion and contraction of the hydraulic cylinder in accordance with the change, and A mechanism that controls the expansion and contraction amount to extend and retract the hydraulic cylinder, opens and closes the upper and lower induction disks to obtain the optimal air volume for the wind turbine, and directs the wind volume with high power generation efficiency Control. FIG. 1 is a block diagram showing a wind speed control apparatus according to an embodiment of the present invention. FIG. 1 is a diagram for explaining the principle of the present invention. A wind turbine 4 using a universal joint 11 to support an upper disk 2 and a lower disk 3 on a smooth surface using a hard synthetic resin reinforced with a lightweight metal or a reinforcing fiber, and using the tower 1 as a rotation axis. And put it up and down. Hydraulic cylinder A located at an equal angle from the center of the tower 1 to the upper guide disk 2 and lower guide disk 3
5, the upper and lower parts are connected by a hydraulic cylinder B6 and a hydraulic cylinder C7. As shown in the flow chart of FIG. 6, first, it is confirmed whether or not each sensor operates normally, and the operation will be described in accordance with Y in which automatic operation is performed and operation proceeds normally. After the detection of the wind direction by the anemometer 9, the detection of the upper and lower guiding disk angles by the guiding disk angle sensor 8g, and the detection of the wind speed by the anemometer 8, the minimum opening angle with respect to the wind speed is calculated. , C, to the target value. If the wind speed at this time is an angle at which it is not necessary to adjust the angle of the induction disk, the hydraulic cylinders A, B, and C operate so that the angle moves toward the wind direction as it is. Next, the guidance disk air volume sensor 8a detects the air volume, and if the air volume is within a specified range, the brake 12 is released and the windmill starts operating. Furthermore, the guidance disk air volume sensor 8a detects the air volume and finely adjusts the optimal air volume that can be created by the operation of the guidance disk using a hydraulic cylinder. If the reverse rotation detection sensor 8f does not operate and the rotation is normal, the power generation capacity sensor 8h sends data to the wind turbine condition monitoring. Next, the heat generation temperature of the generator is detected by the temperature sensor 8d. If the windmill rotation sensor 8c is also normal, the system returns to the head and repeats the detection and determination to monitor the system. At this time, the information of each sensor is monitored as the state of the windmill. In this manner, the microcomputer control performs processing within a range of a preset value.
Operated by a program. In the maintenance mode, manual stop and manual return can be performed at the time of maintenance and inspection. At the time of abnormal stop due to the detection of an abnormality by the sensor, the guiding disk 2, the guiding disk 3,
Is leveled to operate the brake 12, and an alarm is notified to the monitor. In this way, by opening and closing the hydraulic cylinders in combination with the expansion and contraction of each hydraulic cylinder with respect to the omnidirectional wind direction centering on the tower 1, the optimal air flow for the windmill is continuously controlled. As shown in FIG. 3, the rotation energy of the wind turbine is guided to the generator 20 by the hydraulic pump 17, the hydraulic pipe 18, and the hydraulic motor 19, so that the location where the generator is installed is not limited and the location where the maintenance is easy. There is a feature that can be installed. FIG. 5 shows two wind power generators having the above-mentioned features mounted on the same axis of one tower. FIG. 9 is attached with an equation for calculating an approximate value of the wind speed passing between the upper and lower guide disks in the present invention. The high wind speed is a favorable condition for wind power generation in order to increase the power generation efficiency. However, by providing the induction disk of the present invention, it is not necessary to unilaterally increase the air flow, The wind receiving energy of the wind turbine of the generator can be suppressed, and the cut-out wind speed of the wind turbine can be increased. When the wind speed is low, the cut-in wind speed (wind speed at which power generation starts) can be reduced by the wind collecting effect. From low wind speed to high wind speed, the usable range can be expanded. [0015]
