The problem of, it is ensured that the normal operation of wind-driven generator has saved cost.Below in conjunction with the accompanying drawings, it is described in detail according to the present invention
The wind-driven generator wind vane fault redundance operation method and system of embodiment.
Fig. 1 is the flow chart of wind-driven generator wind vane fault redundance operation method according to embodiments of the present invention.The wind
Power generator wind vane fault redundance operation method includes：Step S101：The wind that acquisition is exported by the airspeedometer of wind-driven generator

And step S103：When the wind vane of wind-driven generator breaks down, the changing rule based on air speed value judges whether wind direction is sent out
Changing, so as to which the yaw of the wind turbine of wind-driven generator be controlled to operate.
In one exemplary embodiment, airspeedometer is vane airspeedometer, including being mutually 120 ° of 3 be fixed on stent
Parabolic cone sky cup：Vane 102, vane 103 and vane 104, they form the induction part of airspeedometer, and the concave surface of empty cup is all forward
One direction.Entire induction part is mounted on a vertical rotating shaft, and under the action of the forces of the wind, vane is around axis to be proportional to wind
The rotating speed rotation of speed.Airspeedometer is rotated in the effect of wind-force.According to following mechanical equation：
F=m ω2r (1)
Wherein, F is the wind-force acted on vane, and ω is the angular speed of anemobiagraph rotation, the radius of r vanes rotation；From
Equation (1) can be seen that the wind-force acted on vane is bigger, and anemobiagraph rotating speed is faster, and wind-force is smaller, and anemobiagraph rotating speed is also got over
It is small；And air speed value and tachometer value size have relationship, according to following wind speed and the operational equation of wind-force：
F=ρ * S* (v*sin θ)2 (2)
Wherein, F is the wind-force acted on vane, and ρ is atmospheric density, and S is the area that wind-force acts on vane, and θ is
Wind direction and the angle of vane concave surface.Can be seen that from equation (2), anemobiagraph when rotated, the size and vane of suffered wind-force
Active area by wind-force is related with angle.

It is the schematic diagram for showing that the concave surface of wind direction and an empty cup is tangent according to embodiments of the present invention.
As shown in Fig. 2, when wind direction 101 is vertical with the section on the concave surface vertex of an empty cup (for example, vane 104), wind
Wind-force suffered by fast instrument is maximum, and the tachometer value of anemobiagraph reaches a peak value at this time, therefore the wind speed of anemobiagraph output also reaches
Peak value；As shown in figure 3, when the concave surface of wind direction 101 and an empty cup (for example, vane 104) is tangent, the wind-force suffered by anemobiagraph
Minimum, at this time the tachometer value of anemobiagraph reach a low ebb value.It can be seen that in the rotary course of airspeedometer, each week is all
It can undergo that wind-force is maximum, wind-force minimum two states, since anemobiagraph has 3 vanes, so anemobiagraph is in rotary course,
It often rotates a circle, will appear 3 minor peaks, 3 the lowest point values in the data of anemobiagraph output.And wind driven generator controller acquisition wind
The period of fast value can be, such as 20ms, that is, every 20ms acquisition primary air velocity values.

Peak number is counted using counter, timer is started with when detecting the first peak value and carries out timing, works as counting
When the count value of device increases 4 times newly, timer output timing time t；Step S1024 is acquired based on duration t and in duration t
All air speed values arrived calculate the mean wind speed value v in duration t；And step S1025, determine mean wind speed value and duration t's
Product.In the case where wind vane does not break down and wind direction does not change, mean wind speed value and the product of duration t are predetermined
Value C1.And when wind vane breaks down, the product of mean wind speed value and duration t are C2.
In one exemplary embodiment, predetermined value C1 can also be calculated by following equation：C1=360*r, wherein, r is
The radius of vane rotation.Specifically, following equation can be obtained according to formula (1) and formula (2)：
ρ*S*(v*sinθ)2=m ω2R........................... (3) and based on equation below：
C=ω * t (4)
Wherein ω is mean angular velocity of the anemobiagraph in timing time t, and t is that 4 wind speed peak values institutes of timer statistics are defeated
The timing time gone out, in the case where wind direction is designated as breaking down and wind direction does not change, C is fixed 360 °；And by
In
V=r*w (5)
Wherein, v is the mean wind speed in time t, in the case where wind vane does not break down and wind direction does not change,
C1=v*t=r* ω * t=r*360 (6)
Therefore the radius that vane can be rotated and 360 product are as fixed value C1.
In one exemplary embodiment, when wind vane breaks down, judge the whether changed processing packet of wind direction
It includes：Comparison result based on mean wind speed value v Yu the product C2 and predetermined value C1 of duration t, judges whether wind direction changes.Such as
The product C2 of fruit mean wind speed value v and duration t is equal to predetermined value C1, then judges that wind direction does not change, and otherwise judges wind direction
It changes.
After wind vane failure, if the product C2 of mean wind speed value v and duration t that a certain moment newly calculates is more than in advance
Definite value C1, i.e. C2 ＞ C1, then it represents that vane is moved to left by the position of wind-force maximum, i.e., vane is sent out by the time of wind-force maximum
Delay is given birth to, then left avertence has occurred in wind direction, wind turbine is controlled to start left drift at this time；If the average wind that a certain moment newly calculates
The product C2 of speed value v and duration t is less than predetermined value C1, i.e. C2 ＜ C1, then it represents that the right side is had occurred by the position of wind-force maximum in vane
It moves, i.e., vane is had occurred in advance by the time of wind-force peak value, then right avertence has occurred in wind direction, and wind turbine is controlled to start right avertence boat at this time；
So as to fulfill the redundancy control capability of wind driven generator yaw after wind vane failure.
It in one exemplary embodiment, can be with since the rotation angle of the corresponding airspeedometers of predetermined value C1 is 360 degree
Yaw angle Y is calculated according to equation below：
Therefore, the yaw angle Y of wind turbine can be calculated according to equation below in step S102：
Y=| C2-C1 | * 360/C1 (8)
Wherein, C2 is the product of mean wind speed value and duration t, and C1 is predetermined value.
In one exemplary embodiment, when predetermined value C1 and the mean wind speed value that calculates and duration t product C2 not
When equal, yaw operation is performed to wind-driven generator and is included：When between mean wind speed value and the product C2 of duration t and predetermined value C1
