The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
Referring to fig. 1, the present embodiment provides a control method (hereinafter, referred to as a control method) for suppressing an overspeed of a fan, where the control method includes:
s11: acquiring an actual rotating speed value and an actual acceleration value of the wind generating set;
s12: performing per-unit processing on the actual rotating speed value and the actual acceleration value according to a first preset rule to obtain a per-unit value;
s13: processing the per unit value, the first preset parameter and the second preset parameter according to a second preset rule to obtain a control parameter for controlling the change rate of the pitch angle value, wherein the first preset parameter is smaller than the second preset parameter;
s14: and adjusting the pitch angle value of the wind generating set according to the control parameters and a third preset rule.
It can be understood that, in the actual use process, the larger the external wind speed is, the larger the turbulence intensity is, and the actual speed value and the actual acceleration value of the wind generating set are also increased correspondingly. That is, the magnitudes of the actual speed value and the actual acceleration value can represent the turbulence intensity of the outside.
It should be noted that in the present embodiment, the turbulence intensity is used to describe the degree of wind speed variation with time and space, and reflects the relative intensity of the wind speed.
It will be appreciated that in the present embodiment, the control parameters for controlling the pitch angle value change speed comprise a variable actual rotational speed value and a variable actual acceleration value. That is, the control method can adjust the conversion rate of the pitch angle value in real time according to the change of the actual rotating speed value and the actual accelerating value. Therefore, the wind generating set can quickly make a response of changing the pitch angle value according to the change of the wind speed. The control method can effectively solve the problem that the pitch variation speed of the wind generating set is low.
It should be noted that, in the actual use process, after the pitch angle value is changed, the turbulence intensity increases with the increase of the wind speed, and by using the control method in this embodiment, the rotation speed change rate and the acceleration change rate of the wind turbine generator system can be effectively reduced, so that the effect of inhibiting the rotation speed of the wind turbine generator system from rapidly increasing is achieved, and the probability of overspeed of the rotation speed of the wind turbine generator system under the condition of large turbulence intensity is reduced.
Specifically, in this embodiment, the first preset rule is:
wherein epsilon is a per unit value; e is the difference value between the actual rotating speed value and the preset rotating speed value; omega0Is a preset rotating speed range value;is the actual acceleration value;is a preset maximum acceleration value.
In this embodiment, ω is0The method is characterized in that the rotating speed range value is preset, and the rotating speed variation range of the wind generating set under the normal turbulent wind condition is represented.The maximum value of the acceleration is preset, and the variation range of the acceleration of the wind generating set under the normal turbulent wind condition is represented. And e is the difference value between the actual rotating speed value and a preset rotating speed value, wherein the preset rotating speed value is the rotating speed value under the normal turbulent wind condition. Presetting a rotation speed value omega0Andcan be counted out in normal turbulent wind conditions, and will not be described in detail here.
Note that the normal turbulent wind condition described above is a wind condition with a turbulence intensity of 0.14.
It should be noted that, in other embodiments, e in the first preset rule may also be directly replaced with the obtained actual rotation speed value.
In the present embodiment, the control parameter includes kp、kiAnd kdThe third preset rule is:
is the rate of change of the pitch angle value (i.e., the pitch rate); e is the difference value between the actual rotating speed value and the preset rotating speed value;is the actual acceleration value;is composed ofThe differentiated value.
With reference to the formula in the third predetermined rule, it can be understood that k is changedpCan be changed in sizeSo that the transformation rate of the pitch angle value can be changed. Similarly, change kiCan change the transformation rate of the pitch angle value. Changing kdCan also change the transformation rate of the pitch angle value.
It should be noted that, in this embodiment, the first preset parameter includes kp1、ki1And kd1The second preset parameter includes kp2、ki2And kd2，kp2>kp1，ki2>ki1，kd2>kd1Per unit value is ε, and the control parameters include kp、kiAnd kd；
The second preset rule includes:
kp＝ε*kp2+(1-ε)kp1
ki＝ε*ki2+(1-ε)ki1
kd＝ε*kd2+(1-ε)kd1。
it can be understood that, in this embodiment, the second preset rule is to perform interpolation processing by combining the per unit value epsilon with the first preset parameter and the second preset parameter. And according to the epsilon value, selecting a proper control parameter between the first preset parameter and the second preset parameter according to a second preset rule, and adjusting the conversion rate of the pitch angle value.
That is, when the value of ε is large (close to 1 with respect to 0), the actual rotational speed value and/or acceleration value at that time is large as can be seen from the formula of the first predetermined rule. Thus, according to the second preset rule, the new control parameter k is obtainedpIs closer to kp2、kiIs closer to ki2、kdIs closer to kd2In this case, the pitch angle value can be adjusted faster as known from the third predetermined rule.
It should be noted that, in this embodiment, in the process of obtaining a new control parameter by performing interpolation processing on the per unit value, the first preset parameter, and the second preset parameter according to the second preset rule, smooth transition between the first preset parameter and the second preset parameter is realized, and stationarity in the whole process is ensured.
It is noted that, in this embodiment, the step of adjusting the pitch angle value of the wind turbine generator set according to the control parameter and the third predetermined rule includes:
when in useWhen increasing, make kpAnd is increased.

when e increases, let kiAnd is increased.
It will be appreciated that the above-described,numerically and actuallyThe phase of the two phases is equal to each other,when increasing, this means that the actual acceleration value of the wind turbine generator system is larger, and in this case, k is increased appropriately in this embodimentpIn turn, the rate of change of the pitch angle value may be increased.
Similarly, e is the difference between the actual rotation speed value and the preset rotation speed value, and when e is increased, it means that the actual rotation speed value of the wind turbine generator system is larger, and at this time, in this embodiment, k is increased appropriatelyiIn turn, the rate of change of the pitch angle value may be increased.
Like this, can be respectively to the size of rotational speed value and acceleration value, control pitch angle value transformation rate has the change of different degrees, and the pertinence is stronger, the effectual transformation rate that increases pitch angle value reduces the risk that the fan is overspeed.
Specifically, it should be noted that, in the present embodiment, in the case where e is increased, when the actual rotation speed value ω does not exceed ω11.01, let ki＝ε*ki2+(1-ε)ki1. When omega exceeds omega11.01, let ki’＝Gain2*kiAt this time, kiIs a value interpolated by a second predetermined rule, and ki' is a value substituted into a third preset rule, i.e., k in the third preset ruleiIs replaced by ki’。
Wherein,ω*for a predetermined value of speed, omega0In order to preset the value of the rotating speed range,and limiting 1. ltoreq. Gain2≤3。
In addition, in the present embodiment, inIn case of increase, when the actual acceleration value(on the mathematical relationship) Not exceedWhen, let kp＝ε*kp2+(1-ε)kp1When the actual acceleration value isExceedWhen, let kp’＝Gain1*kpAt this time, kpIs a value interpolated by a second predetermined rule, and kp' is a value substituted into a third preset rule, i.e., k in the third preset rulepIs replaced by kp’。
Wherein,in order to preset the maximum value of the acceleration,and limiting 1. ltoreq. Gain1≤3。
Therefore, the pitch rate can be adjusted in a targeted manner according to the rotating speed value and the acceleration value in different ranges.
