- the torque per blade of blade 10 (the force that the wind turbine tries to rotate by receiving the wind force, and the unit is [N ⁇ m]) is the wind turbine shaft rotation angular velocity [0 ], which is determined by the wind direction and wind speed (corresponding to the wind speed vector [V]) received by the blade 10 and the pitch angle of the blade 10, so that the wind turbine torque T at time ⁇ + i ⁇ t ( t) is the following formula
- This function T j ([ ⁇ ], V j, a j) is measured or simulated in advance so that it can be calculated by the controller 40 or the signal processing unit 300.
- step 403b optimization of the pitch angle for t seconds (step 403b) will be described. Since the wind turbine shaft rotation angular speed [ ⁇ ] is constant and the wind direction and wind speed (corresponding to the wind speed vector [V]) can be predicted t seconds after the blade 10 receives, use Equation (8). Thus, at time ⁇ + ⁇ , the optimal pitch angle ⁇ ′ (+ + ⁇ +) at which the maximum torque can be obtained can be calculated. Therefore, the optimal pitch angle ⁇ ; 'that can be predicted at time ⁇ is
- the controller 40 adjusts the pitch angle to the optimal angle ⁇ .
- a pitch angle control signal of + ⁇ 1: is transmitted to the pitch angle control drive device 60 (step 404b), and the pitch angle control drive device 60 receives this signal to change the pitch angle (step 4).
- the wind direction and wind speed at the current time ⁇ used in the calculation should be measured values (actual data) (Step 406 b).
- the pitch angle of all blades 10 is optimally controlled by repeating for each of the blades 10 of the three main blades. And, of course, and Wind data obtained from the laser-type wind anemometer (observations) in groups, which in other than techniques may predict controlling the pitch angle.
- the change in the wind speed is a perceived force. If the pitch angle is changed, the blade performance is significantly affected, and if the wind direction changes while the pitch angle is changed. Was adversely affected. Also, when measuring the wake after passing through the blade 10 above the nacelle 20 with a mechanical wind direction anemometer, the cycle is about 1 second from the blade 10 (varies according to the windmill speed). And the pitch angle could only be changed based on the average value for one second. Also, during actual control, there was a delay in the response of the machine, etc., so only passive control with a considerable delay was possible.
- the above-mentioned method enables active control of the yaw angle, pitch angle, etc., in consideration of the response delay of the machine, and the blade 10 continues to receive the wind almost at the optimum pitch angle. Can be. Therefore, wind energy can always be used with higher efficiency than conventional passive control. Conversely, it can also be used to suppress output by suppressing the generated torque. In this case, if the optimum pitch angle in Expression (10) is arbitrarily set so as to suppress the generated torque, the output can be easily suppressed. In this way, the wind power generator can be easily and accurately controlled.

- the wind energy is controlled by changing the direction of the wind turbine and pitch control by changing the angle of the blades, thereby controlling the input energy of the wind power and controlling the output of the wind power generation system.
- the measurement range of the laser-type anemometer requires a sufficient amount of time for system control, but a distance of about 20 Om is usually sufficient. That is, generally, the rated wind speed of a wind power generation system is 10 to 2 Om / 's, but if the wind direction wind speed of about 20 Om is known, it takes at least several seconds for the wind to reach the windmill. It takes up to several tens of seconds, and this time is sufficient as time for predictive control of the wind turbine.

DC capacitor voltage rises. The difference between this DC capacitor 811 voltage and the DC voltage reference given in advance as a command value is amplified to obtain the active current command on the AC side (system power converter 8110b side), and the active current is Power is discharged to the grid by increasing control.
