Abstract

PURPOSE:To safely perform the start control at a high wind velocity and positively improve the startability at a low wind velocity by changing a blade setting angle in steps to the blade setting angle during the normal rotation when starting blades in a stop condition. CONSTITUTION:The blade angle of a wind prime mover with a predetermined value of a blade setting angle in a stop condition is changed in steps to the condition of the blade fitting angle beta2 during the normal rotation. By monitoring the operational condition of the wind prime mover at each step, the wind prime mover can be safely started even at a high wind velocity, and also a normal operational condition can be effectively attained. In case the rotation is stopped in a condition of the blade fitting angle beta2 of the normal operational condition at a low wind velocity, the wind prime mover can be positively started at a lower wind velocity by changing the blade fitting angle to a condition where the maximum rotating torque can be obtained.

In order to rotate the blade efficiently and safely at high wind speeds, it is important to adjust the angle at which the blade 1 is attached to the plane of rotation. In Figure 2, β is the blade mounting angle with respect to the rotating plane X of blade 1, β1 is the blade mounting angle β when rotation is stopped, β2 is the blade mounting angle β during normal rotation, and β3 is the maximum torque obtained when rotation is stopped The blade attachment angle is β. As shown in FIG. 3, in general, when the blade attachment angle is β1, almost no rotational torque is generated even at high wind speeds, so that the rotation of the wind motor can be stopped. Furthermore, since output can be obtained most efficiently during rotation at the blade attachment angle β2, this blade attachment angle is set during normal rotation. The state of the deflected blade mounting angle β3 is such that the maximum rotational torque is obtained at the start of rotation, and generally β1>β3>β2, and β
1 is the maximum value and β2 is the minimum value.

きく損われるという欠点も有していた。This is a control to perform normal operation after starting a wind turbine that is stopped at the blade mounting angle β1, but in order to change the blade mounting angle from the state β1 to the state β2 at once. At high wind speeds, it became necessary to immediately change the blade attachment angle β significantly in order to prevent over-rotation. At this time, the mechanism of the blade attachment angle variable device 3 needs to be reversed at once, and there is a danger that safety will be seriously compromised, especially since mechanical delays may cause it to rotate or a large force will be applied to the mechanism. occurred. ′=! However, it also has the disadvantage that the operating efficiency of the wind power plant is greatly impaired because over-rotation occurs and the blade attachment angle β is increased more than necessary.

By monitoring the operating state of the wind motor at this stage, the wind motor can be started safely even at high wind speeds, and can be efficiently brought to normal operating state. In addition, if rotation stops at the blade mounting angle β2, which is the normal operating state, at low wind speeds, by changing the blade mounting angle to a state where the maximum rotational torque can be obtained, the wind engine can be actively operated at lower wind speeds. It can be activated.

実施例の説明 本考案の一実施例を第５図に基づいて説明する。Description of examples An embodiment of the present invention will be described based on FIG.

風力原動機の構成および翼取付角度の値については従来
例と同一番号を付して説明する。The configuration of the wind power motor and the values of the blade attachment angles will be explained using the same numbers as in the conventional example.

図に示すように、翼取付角度β１の状態から風力原動機

に変更し、回転の上昇を監視する。As shown in the figure, when starting the wind motor from a state where the blade mounting angle is β1, first, the blade mounting angle is changed to a smaller value by a set value, and an increase in rotation is monitored.

βを変更した後通常の運転状態に移行するものである。This set value is selected to be changed several times between the blade attachment angles β1 and β2. If the predetermined rotational speed is not reached even after reducing the blade mounting angle β in one step, the blade mounting angle β is further reduced by the set value. In this way, the blade mounting angle is reduced in several stages until a predetermined rotational speed or a blade mounting angle β2 is obtained, and then the normal operating state is resumed.

起動性を得るために効果的である。By starting in this gradual and careful manner,
Even in strong winds, it is possible to safely and efficiently return to normal operating conditions without putting any burden on the variable blade attachment angle device. By the way, when changing the blade mounting angle which has been changed to a large value due to overspeed under normal operating conditions to the state β2 again, a control method is generally considered in which the blade mounting angle is changed step by step by a certain set value. The angle is from β1 to β2,
It is conceivable that this control method could be used to change even the distance. However, in general, the change value of the blade attachment angle in such a case is a small value, and when the blade attachment angle is changed from β1 with this change value, there are many steps and it is very inefficient. On the other hand, in the present invention, the change value when starting from the blade installation angle β1 is based on the change value under normal operating conditions, and the change value is only changed from the blade installation angle β1 to β2 dimension. It is characterized by the fact that it is performed in several stages, thereby realizing extremely efficient startup control. Furthermore, the wind speed is detected by a predetermined detector, and if the wind speed is extremely low, the change value may be increased or β2
If control is carried out to change up to 1, even more efficient start-up performance can be obtained. Also, if the change plane of the blade attachment angle is the same, when the blade attachment angle is close to β2, β
Since the influence on changes in the rotation of the wind motor is greater than when it is close to 1, the blade installation angle β1 should be changed with a relatively large change value at first, and then changed with smaller change values at each step. fjlfil is also effective for obtaining more efficient start-up.

の運用が計り得ることは明らかである。On the other hand, if the wind is weak and the wind motor does not reach the specified rotation speed after the -11,% installation angle reaches β2, the blade installation 3
Instead of waiting in the state of 11 degrees β2, we change the blade mounting angle to β3, which provides maximum rotational torque in the low rotation range, and actively improve the startability of the wind engine by waiting in this state. can be done. In particular, the rotational torque required when starting a wind turbine is against the resistance force due to mechanical system friction, etc., but this reaction force is generally several times smaller once it starts rotating than when it is stationary. . For this reason, it is easier to change the blade attachment angle to β3 and start at a lower wind speed with the rear blade attachment angle β2, compared to the wind speed that can be started with the blade attachment angle β2. It is clear that an effective speed increase can be obtained and efficient wind motor operation can be achieved.

If the rotation of the wind turbine cannot be obtained even when the temperature approaches 1.1, it is possible to control the wind turbine to shift to the normal operating state at that moment and stand by at the blade attachment angle β3.

By changing the state step by step, the wind turbine can be started safely and efficiently even in strong winds.
Furthermore, the transition from a stopped state to normal operation can be performed safely, efficiently, and quickly. In addition, when the wind power plant is stopped during weak winds, by setting the blade mounting angle to the angle that provides the maximum rotational torque, it can be actively started even at lower wind speeds, increasing the operational efficiency of the wind farm #JJ machine. can be improved.
