Description
Technical field
A kind of adjust the present invention relates to wind-driven generator power conditioning technology field more particularly to actively eccentricity formula wind-force
Acc power regulating device.
Background technology
At present, middle-size and small-size wind energy conversion system Poewr control method mainly has three categories by operation principle conclusion:(1) wind wheel is reduced to meet
Wind area；(2) change vane airfoil profile angle of attack value；(3) wind speed round is limited using resistance of the air in wind wheel tangent to periphery wind direction.
Wherein, when wind wheel front face area is that wind wheel is vertical with arrives stream wind speed, the swept area of blade.Under equal wind speed, wind wheel is reduced
The ability that front face area can make wind energy conversion system absorb wind energy reduces, so as to reduce rotating speed.There are mainly three types of realization sides for this method
Formula:
The first is backstroke on wind wheel, and backstroke is the eccentricity of the axis using wind wheel and cabin axis on wind wheel, wind wheel
Axial force one will be generated for cabin make the torque that it rotates around the shaft to upper right side.After wind speed reaches certain value, when
When the torque that wind wheel forms cabin rotating shaft is enough to overcome the torque of tail vane torsional spring and the moment of friction of cabin floating bearing,
Cabin just starts to rotate to the right, deviates the direction of incoming.
Second is lateral-deviation type, and the wind wheel axis of this mode has biased a distance (partially relative to the axial side of revolution
The heart away from), it is different using the aerodynamic force on flank to generate deflection torque from side wing type, it be using wind wheel axis and rotating shaft it
Between eccentricity and cause wind wheel generate deflection torque using the aerodynamic force suffered by itself, the airflow condition with flank complexity
It compares, this mode is more succinct.The new construction that this mode is derived, which has, is tiltedly hinged tail vane lateral-deviation type (also known as gravity return
Formula).
The third mode is folding and unfolding vane type, different from the method for deflecting wind wheel and reducing front face area, folding and unfolding vane type
Wind energy conversion system by spring by vane hinge mainly by rotor shaft, and keeping its initial position.When wind speed is excessive, blade
The Pneumatic pressure being subject to overcomes spring to act on, and so that blade down the wind tilts, so as to achieve the purpose that reduce front face area,
This method is generally mostly used by middle-size and small-size wind energy conversion system.
Above-mentioned lateral-deviation type wind energy conversion system power control mode eccentricity is set in initial installation, eccentricity size
It is set according to target power, the later stage is unadjustable, and when aerodynamic force is excessive suffered by wind wheel, deflection torque is more than the range that can be born
When, wind wheel deviates wind direction, appropriate to reduce wind wheel front face area, but whether the power of wind energy conversion system can meet the requirements after wind wheel deflection
It cannot learn, even if cannot meet the requirements, can not be adjusted again.
In addition, the power control target of middle-size and small-size wind power generating set, which is mainly realized, can send out maximum work under low wind speed
Rate and high wind speed area being capable of speed-limiting protections.In fact, the target of Wind turbines power control should also include according to power load
Variation carries out changed power (power regulation).Existing middle-size and small-size Wind turbine can't realize this point requirement.
Invention content
