In wind power generating set, yaw (Yaw) is one of essential composition system.The main function of yaw system
There are two.One is the control system with wind power generating set cooperates, it is in the wind wheel of wind power generating set always and meets
Wind state, makes full use of wind energy, improves the generating efficiency of wind power generating set；Secondly being to provide necessary locking torque, to protect
Hinder the safe operation of wind-driven generator.Anemobiagraph and wind vane are to realize that wind regime detects most important sensor, wherein anemobiagraph
Effect be realize air speed value measurement, for detect air speed value whether reach threshold wind velocity and detection air speed value whether surpass
Cross maximum cut-out wind speed etc..And wind vane is indispensable device in wind driven generator yaw system, wind vane is as induction
The variation of wind direction is transmitted in the processor of yaw motor control loop by element with electric signal, after processor compares processing
Yaw command clockwise or counterclockwise can be issued to yaw motor, and wind-driven generator is made to execute yaw maneuver.
Below with reference to the detailed structure for introducing wind vane of figure and its structure bring characteristic etc..Referring to Figure 1, wind vane
Structural schematic diagram.As shown, wind vane 200 includes shell 210, with the main shaft being rotatably arranged in shell 210
It 220 and is directed toward the rotary part of bar 230, wind direction measuring circuit 240 and is respectively arranged in the empennage 280 for being directed toward 230 both ends of bar
And counterweight 290.It is directed toward between bar 230 and main shaft 220 and is mechanically connected, wind-force pushes its drive by acting on empennage 280
Main shaft 220 rotates.The principle that wind vane determines the wind direction are as follows: when wind is when coming to wind vane 200 at a certain angle of cut, empennage 280 by
The counterweight 290 of wind area ratio front end is big, and empennage 280 can be postponed by wind, so that counterweight 290 is directed toward the source direction of wind, later
Due to 280 two sides stress equalization of empennage, wind vane 200 is just stablized in a certain position, and wind direction measuring circuit 240 detects rotation axis and turns
The angle value crossed simultaneously is compared with reference position, can obtain wind direction value at that time.Since practical wind direction is transition, then plus
280 frequent swing of empennage caused by upper 290 rotator inertia of counterweight, wind direction frequently change, and then cause wind vane 200 in wind
Under the action of can frequent swing.
According to the calculation formula of wind speed and wind-force, the measurement of wind speed, the calculation formula of wind speed and wind-force are carried out are as follows:
F=ρ * S* (ν * sin θ)2Formula (1)
Wherein, F is the wind-force acted on wind vane empennage, and v is wind speed, and ρ is atmospheric density, and S is the face of empennage 280
Product, θ is the angle of wind direction and empennage 280.It can be seen that from formula (1), since the area S of empennage 280 is fixed value, wind-driven generator
When group does not yaw, the mean value of angle, θ is also approximately at fixed value, so wind speed v is bigger, the power F that empennage 280 is subject to is also bigger；
According to mechanics principle:
F=ma=mw2R formula (2)
Wherein, the equivalent mass that m wind vane 200 rotates, a are acceleration, and w is the angular speed that wind vane 200 rotates, and r is
Radius of turn of the empennage 280 relative to rotary shaft can be seen that from formula (2), since m, r are fixed value, so wind vane tail 280
The power being subject to is bigger, and the angular speed that wind vane 200 is swung is faster.The present invention is according to this principle, to the swing speed of wind vane 200
Rate is counted, and is associated statistics with air speed value.Therefore according to mechanics principle, wind speed is bigger, acts in same area
Power is bigger, so the flutter rate of wind vane 200 is also faster, so carry out wind vane flutter rate and air speed value is associated with system
Meter, can be according to the flutter rate prediction of wind speed value size of wind vane 200.
