The algorithm block diagram one of the oscillation damping method of the wind power generating set of the offer of example two is applied, Fig. 4 is wind-force provided by Embodiment 2 of the present invention
The algorithm block diagram two of the oscillation damping method of generating set, on the basis of embodiment one, as shown in Figure 2, Figure 3 and Figure 4, the present embodiment
Method, control component be AC compounent of the inverted；Then step 102 specifically includes：
The signal of predeterminated frequency range in step 202, extraction generator speed signal, to obtain AC compounent；To exchange
Component is negated, using AC compounent of the inverted as control component.
In the present embodiment, specifically, as shown in Figure 3 and Figure 4, can be gone by estimation mode or speed probe
The generator speed signal of wind power generating set is got, the generator speed signal is then transferred to a low-pass filtering
Device, low-pass filter are filtered generator speed signal, then the power generation after low-pass filter output filtering process
Machine tach signal.
Then, due to the exchange point for having frequency identical with the vibration frequency of wind power generating set in generator speed signal
Generator speed signal after filtering process can be input in a control component processing module, control component first by amount
AC compounent acquisition submodule in processing module extracts processing to the generator speed signal after filtering process, goes to extract
Go out the signal of predeterminated frequency range in the generator speed signal after filtering process as AC compounent, after to filtering process
During generator speed signal extracts processing, need to adjust the centre frequency and wind-force of AC compounent acquisition submodule
The vibration frequency of the vibration signal of generating set is consistent, and needs to carry out gain to the AC compounent in generator speed signal
Processing.Wherein, gain process can be that AC compounent is amplified or AC compounent is reduced.It also, should
AC compounent can be sinusoidal waveform component or be cosine waveform component or other waveform components.
For example, a bandpass filter (Band-Pass Filter, letter may be used in AC compounent acquisition submodule
Claim BPF), bandpass filter extracts processing to the generator speed signal after filtering process, goes after extracting filtering process
Generator speed signal in predeterminated frequency range signal, the signal of the predeterminated frequency range is in generator speed signal
AC compounent.Wherein, during bandpass filter extracts processing to the generator speed signal after filtering process,
The centre frequency of adjustment bandpass filter is needed, and needs to carry out at gain the AC compounent in generator speed signal
Reason.Specifically, due to that can be mounted with a vibrating sensor in wind power generating set, wind is obtained by vibrating sensor
The vibration signal of power generator group, then the vibration signal of the wind power generating set to getting analyze, extract wind-force
Then the vibration frequency and vibration amplitude of the vibration signal of generating set set the centre frequency and wind-power electricity generation of bandpass filter
The vibration frequency of the vibration signal of unit is consistent, and then the parameter of the centre frequency of adjust automatically bandpass filter；Also, to from
The AC compounent extracted in generator speed signal carries out gain process, which can carry out letter to AC compounent
Number amplification or signal reduce, that is, adjust bandpass filter gain value size, and then to AC compounent carry out signal amplification
Or signal reduces.
Then, the AC compounent extracted is conveyed to taking in control component processing module by AC compounent acquisition submodule
Anti- submodule negates submodule and AC compounent is negated, it is possible to obtain AC compounent of the inverted, the friendship of the inverted
Flow component can serve as control component.Specifically, the detailed process negated to AC compounent is：It is in AC compounent
During positive value, the AC compounent+A of positive value is converted to the AC compounent-A of negative value, when AC compounent is negative value, by the friendship of negative value
Flow component-A is converted to the AC compounent+A of positive value, and during this, the absolute value A of AC compounent is constant.

Value.Wherein, summation process is carried out for the quadrature axis current set-point of wind power generating set, with AC compounent of the inverted at addition
Reason.
Wind power generating set blade in a rotational direction, there are impeller it is shimmy the problem of, wind power generating set is shaken
In the present generator speed of kinetoplast, so as to the vibration frequency phase there is frequency and wind power generating set in generator speed signal
Same AC compounent.AC compounent in generator speed signal is extracted, then passes through the parameter value of adjust automatically gain process
With the parameter value of the centre frequency of AC compounent acquisition submodule, and then obtain AC compounent through negating processing, add in
After the quadrature axis current set-point of a synthesis being obtained after to the quadrature axis current set-point of wind power generating set, wind-driven generator
After group is run according to the quadrature axis current set-point of the synthesis, the vibration amplitude of wind power generating set can be dropped to mark
It is accurate following；It and then can be by constantly adjusting the parameter value of adjust gain processing and the center of AC compounent acquisition submodule
The parameter value of frequency, after the quadrature axis current set-point synthesized, quadrature axis current of the wind power generating set according to the synthesis
After set-point is run, continuous adjust gain processing parameter value, centre frequency parameter value when until wind-force
The vibration amplitude of generating set drop to it is below the mark, and then play the role of inhibit unit vibration.
Correspondingly, step 104, specifically includes：
Step 204 controls wind power generating set according to the quadrature axis current set-point of synthesis, to pass through the friendship of synthesis
Shaft current set-point goes counteracting wind power generating set impeller to vibrate in a rotational direction.
In the present embodiment, specifically, specifically, due to by AC compounent of the inverted, with wind power generating set
Quadrature axis current set-point carries out summation process, has obtained the quadrature axis current set-point of a synthesis.As shown in figure 3, by synthesis
Quadrature axis current set-point is transferred to the current controller of wind power generating set so that current controller is electric according to the quadrature axis of the synthesis
Stream set-point is run, and then completes the work of wind power generating set.And exist and hair in the quadrature axis current set-point synthesized
The reversed quadrature axis current signal of 180 ° of oscillating component phase mutual deviation in motor speed signal, and due to the friendship of wind power generating set
Shaft current set-point is directly proportional to motor torque, so as to by the quadrature axis current set-point of synthesis, go to offset wind-force hair in this way
Motor group impeller vibrates in a rotational direction, and then eliminates the shimmy resonance between wind power generating set of impeller.
The present embodiment is by obtaining the generator speed signal of wind power generating set；Signal is carried out to generator speed signal
Processing, to obtain AC compounent；AC compounent is negated, obtains AC compounent of the inverted；By exchange point of the inverted
Amount, the quadrature axis current set-point progress summation process with wind power generating set, the quadrature axis current set-point synthesized；According to conjunction
