る。2. Description of the Related Art Conventionally, an outline of a wind turbine generator has a structure shown in FIG. 5, for example. Reference numeral 1 in the figure indicates a rotary blade (blade) that is rotated by wind. In this rotary vane 1,

る。By the way, in the wind turbine generator shown in FIG. 5, since the induction generator 3 is used, the output cannot be controlled. Therefore, the rotary blades 1 are controlled to have an appropriate pitch angle so as to respond to the incoming wind energy. To generate electricity. Therefore, when the wind becomes very strong (for example, when the wind speed exceeds 25 m / sec), there is a risk that the strength limit of the wind power generation main body will be exceeded. Therefore, in such a case, a so-called cutout is performed in which the pitch angle is changed to allow the wind to escape completely (feathering) and the power generation of the wind power generation main body is stopped. Also,
In addition to when the wind speed is strong, cutout is performed when the device is artificially stopped for maintenance or the like.

In the present invention, "when the wind becomes extremely strong and approaches the limit of the wind turbine main body" means a high wind speed of the cutout wind speed. Here, the cutout wind speed means the maximum wind speed when the output of the wind turbine is generated.

Moreover, the cutout wind speed is about 15 to 25 m / s, and the frequency of winds higher than this is low. Even if the cutout speed is increased too much, the annual output amount only slightly increases, and only the strength requirement increases. is there.

(B) shows a system diagram when a pitch command is issued. In addition, in FIG. 4 (A), the portion surrounded by the alternate long and short dash line means a power command that decreases at a constant speed. That is, normally, the wind speed V
When the rotational speed N is input to the calculator (PID) 31, the calculator 31 calculates the wind speed V and the rotational speed N to obtain the target electric power, and the electric power command is given to the generator. On the other hand, the pitch command is given to the generator by calculating the wind speed V and the rotation speed N similarly to the above.
However, when the wind becomes very strong (the above wind speed) and approaches the wind power generator main body, a cutout command causes the switch to switch from X to Y in FIG. 4 (A), and a command to decrease the output at a constant speed is issued. It is given to the generator and gradually reduces the output.
