出し、この検出信号にもとづいて風車の方向制御
をおこなつている。 Wind power generators generate electricity by using wind to turn a windmill, which then turns a generator directly connected to the windmill. At this time, the greatest rotational force can be obtained by oriented the windmill directly in the direction of the wind. For this reason, conventionally, the wind direction is detected using a wind vane, and the direction of the wind turbine is controlled based on this detection signal.

風向計の遊転信号により風車が動かされ、無駄な
動作を続ける欠点がある。 However, in light winds of 1 to 2 m/s, the blades do not rotate, but the wind vane rotates freely. For this reason, the windmill is moved by the wind vane's idle signal, which has the drawback of continuing its useless operation.

The purpose of this is to cut off the idle signal and prevent direction control during light winds.
It is an object of the present invention to obtain a direction control device for a wind turbine that does not continue unnecessary operations.

いる。 The present invention will be described below with reference to illustrative embodiments. The drawing is a block diagram showing a wind turbine direction control device. This direction control device includes a wind direction control system that causes the wind direction of the wind turbine 1 to face directly, and a control system opening/closing means that opens and closes this control system. The wind direction control system inputs a wind direction signal from the wind vane 2 to the electric motor 4 via the fixed contact 3a of the relay 3. This electric motor 4 directs the wind turbine 1 directly connected to the generator 5 to face the wind direction based on the wind direction signal.
Its drive shaft is connected to the wind turbine 1 via a gear 6.

にしている。 Further, the control system opening/closing means converts the wind speed signal from the anemometer 7 into an electrical signal using a converter 8 and inputs the electrical signal to a monitor 9. Monitor 9 shows a breeze (1~
2m/sec) is input in advance, and when the input signal and the set value are compared, if the input signal is large, the relay 3 will not operate and the movable contact 3b will remain closed to the fixed contact 3a. However, when the input signal is small, the relay 3 operates to open the fixed contact 3a. Note that 10 in the figure is a wind speed indicator. Further, this device is provided with an automatic/manual changeover switch (not shown) so that the opening/closing means is bypassed when manually controlling the direction of the wind turbine 1.

(seconds or more), the fixed contact 3 of relay 3
a is closed, and the wind direction signal from the anemometer 2 is input to the electric motor 4. The electric motor 4 rotates by an amount proportional to the wind direction signal, so that the wind turbine 1 faces the wind direction.

時の遊転を防止することができる。 On the other hand, when the wind speed is below the set value (below 1 to 2 m/sec), the monitor 9 excites the relay 3, opening the fixed contact 3a. As a result, the wind direction signal from the anemometer 2 is not input to the motor 4, the wind turbine 1 does not rotate, and free rotation in light winds can be prevented.
以上の如く本考案によれば、微風時に風向信号
をカツトして風車の遊転を防止することができ
る。 As described above, according to the present invention, it is possible to prevent the wind turbine from idling by cutting off the wind direction signal when the wind is light.
