Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, outlet air motor speed regulating method provided in an embodiment of the present invention, including：
Step 101, master control borad to go out wind turbine apply step signal controlled quentity controlled variable, the step signal controlled quentity controlled variable for changing
It is described go out wind turbine rotating speed；
Go out at least two parameters pair of wind turbine during rotating speed changes, institute described in step 102, master control borad detection
Parameter is stated to for time parameter and corresponding rotary speed parameter；
Step 103, the master control borad according to the step signal controlled quentity controlled variable and at least two parameter pair, determine described in
Go out the load transfer function coefficient value of wind turbine；
Step 104, the master control borad go out the load transfer function coefficient value of wind turbine according to, and wind turbine fortune is gone out described in control
Row.
In above-mentioned steps 101, master control borad applies step signal controlled quentity controlled variable to going out wind turbine, wherein step signal controlled quentity controlled variable
For changing it is described go out wind turbine rotating speed, also, master control borad to go out wind turbine apply step signal controlled quentity controlled variable time point can
To be：For master control borad when detecting out that wind turbine powers on, to going out, wind turbine applies step signal controlled quentity controlled variable or master control borad exists
When receiving remote control command, apply step signal controlled quentity controlled variable to going out wind turbine.
In above-mentioned steps 102, since master control borad applies step signal controlled quentity controlled variable to going out wind turbine, thus lead to wind turbine
Rotating speed change, usually rotating speed is getting faster, and then reaches some time point, and rotating speed tends towards stability, in the process,
Master control borad detects at least two parameters pair of wind turbine during rotating speed changes, the parameter to for time parameter with it is corresponding
Rotary speed parameter.
For example, detect two parameters to for：(t1, y1), (t2, y2), wherein first parameter is to indicating in t1Moment
The rotating speed for going out wind turbine is y1, second parameter is to indicating in t2The rotating speed for going out wind turbine at moment is y2；Certainly it can also be inspection
It surveys and obtains multiple parameters pair, for example, 3,4,4 or with first-class.
Certainly, parameter is obtained to can also be by following methods：
Master control borad obtains the corresponding rotating speed of each sampling time point according to the preset sampling period, until going out wind turbine

Point and the corresponding rotating speed of sampling time point, determine the rotating speed of wind turbine and the correspondence of time；State master control borad from turn
Speed and determining at least two parameters pair in the correspondence of time.
That is master control borad first according to the correspondence at time point and rotating speed sampled, determine out the rotating speed of wind turbine with
The correspondence of time, such as can be a functional relation or the curve relation figure of a time and rotating speed, according to
Go out the rotating speed of wind turbine and the correspondence of time, can therefrom choose at least two time points, and determine with this at least two
Time point corresponding rotating speed.
The above method determines correspondence first, and the method for then determining parameter pair again is advantageous in that：It can spirit
The parameter pair on non-sampled time point is got livingly, to be conducive to the speed that master control borad improves calculating parameter value.
In above-mentioned steps 103, master control borad determines wind-powered electricity generation according to step signal controlled quentity controlled variable and at least two parameter pair
The load transfer function coefficient value of machine.
As an example it is assumed that transmission function is y=K*U (1-e-(t-τ)/T), wherein U is the step signal controlled quentity controlled variable, t
For time variable, y is speed variables, and K, T, τ is the load transfer function coefficient value, wherein T is system time constant, and τ is system
Pure delay time, K are output gain.
That is K, T, τ as need the load transfer function coefficient value acquired.It is given below two kinds and acquires load transfer function coefficient value
Method, including：

I.e. in above-mentioned steps 102, two parameters pair are obtained, it is assumed that two parameters of acquisition are to being respectively：(t1,
0.37Y) and (t2, 0.63Y), wherein Y represents rotating speed when wind turbine speed tends towards stability.
Also, in the embodiment of the present invention, the sampling period for going out the parameter pair of wind turbine is very small, therefore, can be approximately considered
When t tends to infinity, rotating speed when outlet air motor speed tends towards stability has Y=K*U.
Thus, following equation group can be obtained：
So as to obtain：K=Y/U, τ=2t1-t2, T=2 (t1-t2)。
Method two, the quantity of parameter pair are more than 2
Master control borad according to the step signal controlled quentity controlled variable and multiple parameters pair, determine described in go out the transmission function ginseng of wind turbine
Several multigroup calculated values；Master control borad according to multigroup calculated value, determine described in go out the load transfer function coefficient value of wind turbine.
Assuming that there are two parameters to being respectively：(t3, 0.55Y) and (t4, 0.87Y).
Thus, following equation group can be obtained：
So as to obtain：K=Y/U, τ=(5t3-2t4)/3, T=5 (t3-t4)/6。
Then, it can be calculated：
K=Y/U,
This method two is the average value for seeking multiple result of calculations, so as to more accurately obtain current transmission function ginseng
Numerical value.
