Based on wind energy conversion system air sky theory of mechanics, (such as tip speed ratio, wind wheel is straight for labor research blade key parameter
Footpath, Reynolds number, Airfoil Aerodynamic Performance and blade loading etc.) influence to wind mill performance；And then adopted on whole blade design
With the wind mill airfoil series of brand-new design, propose to be up to multiple-objection optimization with Maximun power coefficient and unit area generated energy
Model, using chord length, torsional angle as design variable, blade loading is effectively controlled to establish novel wind motor to improve blade fatigue life

Number, design a model pneumatic equipment bladess；
The blade profile parameter that 3rd step is constructed to wind mill airfoil carries out local improving and repairing type, mainly for blade tip
Remodeling, obtain the pneumatic equipment bladess that blade tip is in W type structures.
In order to which accurate test blade tip comprehensively is without the noise characteristic of W types fluting and the wind energy conversion system of tip band W types fluting, utilize
Acoustic array method adjust the distance the wind wheel Plane of rotation 30cm sections anglec of rotation for 90 ° when p-wire on 7 measuring points tested.Its
Test zone 3-D walls and floor is defined as, vertical with wind wheel rotary shaft and pass through the plane of pneumatic equipment bladess blade tip aerofoil profile leading edge point
Wind wheel Plane of rotation is defined as, the intersection point of wind wheel rotary shaft and the plane is wind wheel pivot, along wind wheel pivot aweather
Wheel Plane of rotation radial direction outwards moves horizontally 30cm and is arranged to origin of coordinates O.Each measuring point interval 10cm on p-wire,
Shown in specific test arrangement schematic diagram 2.
In the present embodiment, it is W types blade tip 1 (a=1.4cm, h=respectively using 2 kinds of various sizes of W types blade tips
2.5cm, θ=28 °) and W types blade tip 2 (a=1.4cm, h=5.4cm, θ=14 °), then test after not retrofiting and retrofiting 2 kinds not
With the external characteristics of W type tip structure wind energy conversion systems, the relationship change curve of its wind speed and power is shown in Fig. 3, wind speed and wind energy utilization system
Number Cp change curves are shown in Fig. 4.It can be seen from Fig. 3 and Fig. 4 in measured wind speed range between 3-14m/s, W types blade tip 1
The power output and power coefficient of wind energy conversion system are not retrofited wind energy conversion system less than blade tip；In the low wind speed ranges of 3-7m/s, W type blade tips
2 wind energy conversion system power outputs and power coefficient are not retrofited wind energy conversion system, in 7-14m/s in the range of high wind speed, W types higher than blade tip
The wind energy conversion system output work of blade tip 2 and power coefficient rate are not retrofited wind energy conversion system and the wind energy conversion system of W types blade tip 1 less than blade tip.Thus may be used
See, W type blade tip height h size has considerable influence to wind energy conversion system power performance in low middle wind speed section, high wind speed section influence compared with
It is small, and the wind energy conversion system of W types blade tip 2 is more slightly larger than influence of the wind energy conversion system of W types blade tip 1 to wind energy conversion system external characteristics.Rated wind speed 13m/s institutes are right
It is respectively that blade tip is not retrofited the wind energy conversion system 304W of 1 wind energy conversion system 307W, W type blade tip of wind energy conversion system 316W, W type blade tip 2 to answer power.Pass through meter
Calculate, power drop 2.8% after the wind energy conversion system of W types blade tip 1 remodeling, power drop 3.8% after the wind energy conversion system of W types blade tip 2 remodeling, thus may be used
Know, the W type tip structure wind energy conversion systems after remodeling influence little on wind-force acc power and wind energy utilization.
In the present embodiment, anterior-posterior horizontal axle wind mill wind wheel blade tip of being retrofited to the lower blade tip in specified tip-speed ratio λ=7.5 is passed through
The analysis of downstream 3D region noise pattern, the spectrogram of Axis Wind Turbine With A Tip Vane noise region is mainly by the rotation of wind wheel blade
Turn blade tip vortex shedding frequency caused by fundamental frequency and harmonic wave, blade rotation, frequency caused by the rotation of wind-tunnel power fan is formed.We
It is W types blade tip 1 (a=1.4cm, h=2.5cm, θ=28 °) and (a of W types blade tip 2 respectively using 2 kinds of various sizes of W types blade tips
=1.4cm, h=5.4cm, θ=14 °), 2 kinds of different W types tip structure wind energy conversion systems are then tested after not retrofiting and retrofiting in incoming
During wind speed 13m/s, corresponding to the rotation fundamental frequency 72Hz for 7 measuring points that tip-speed ratio λ=7.5, x=30cm the test anglec of rotation is 90 °
Rotational noise change see Fig. 5, Fig. 6 is shown in the change of blade tip noise corresponding to blade tip vortex shedding frequency 357Hz.
As seen from Figure 5, rotation fundamental frequency and its harmonic relationships are made on influence caused by the rotational noise of wind wheel after blade tip remodeling
Frequency corresponding to spectrogram peaks (namely rotational noise) have the trend being decreased obviously in test zone.From Fig. 6
It can be seen that blade tip is not retrofited, wind energy conversion system and the wind energy conversion system of W types blade tip 1 have tip vortex to pass through in measuring point 5 so that the tip vortex noise of measuring point 5
Sound pressure level rise；The wind energy conversion system of W types blade tip 2 has tip vortex to pass through in measuring point 6 so that the sound pressure level liter of the tip vortex noise of measuring point 6
Height, but do not retrofit blade tip below.It follows that the generation of tip vortex noise and rotational noise is reduced after blade tip remodeling,
And blade tip height h turns into an important factor for influence tip vortex noise size and tip vortex movement locus.
Tested by wind energy conversion system external characteristics, it is found that wind energy conversion system power performance is not because W types blade tip height is different after retrofiting
There is different changing rules with wind speed section, wherein W types blade tip height is higher, and its power characteristic and power coefficient are in low wind speed
Section has a great influence, and the rated power of its wind energy conversion system has and declined more by a small margin with the increase of W type blade tip height.In tip-speed ratio λ
Under=7.5, the test for anterior-posterior horizontal axle wind mill wind wheel blade tip downstream 3D region acoustic radiation influence of being retrofited by W types blade tip,
It was found that the spectrogram peaks corresponding to the frequency of wind wheel rotation fundamental frequency and its harmonic relationships are made to have the trend being decreased obviously after remodeling.
W types blade tip has an impact to the spectrogram peaks corresponding to the shedding frequence of tip vortex simultaneously, is allowed to reduce, the height of W type blade tips
Degree determines wind wheel rotational noise and the degree that tip vortex noise reduces, and blade tip, which highly turns into, influences wind wheel rotational noise, blade tip
The important parameter of whirlpool noise and tip vortex movement locus.
By the remodeling to tip structure, a kind of blade tip provided by the invention is in the pneumatic equipment bladess and wind-force of W type structures
Machine, in the case where ensureing that power output is basically unchanged, Axis Wind Turbine With A Tip Vane noise is reduced, reduces the degree of fatigue of blade, is extended
Wind energy conversion system service life.
