The present invention relates to a kind of being used for reduces load in the power train of wind energy plant, especially torsional vibration and device and method static and dynamic bending moment.
Existing technology
By parts driving mechanism for example, the power train that coupling piece and connecting element (axle) are formed is that various electric energy produce for example wind energy plants of equipment, the important component part of hydraulic set or the like.
Power train is carried out such task, and the connection of promptly between drive unit (the for example rotor of wind energy plant) and output unit (for example corresponding generator), setting up machinery through this connection, is transmitted energy through rotational motion.Power train part such as driving mechanism be used for be applied on the drive unit rotating speed and torque conversion to the corresponding value of the operating range of generator.Coupling piece connects between the parts that axle is being participated in separating between drive unit and the output unit needing to be used under the situation.Other parts such as mechanical brake or like also can be incorporated in the power train.
Because the parts of participating in can not at random be made rigidly, but have final rigidity, so they can be energized the generation self-vibration.A kind of such excitation for example can cause through non-constant input power (under the wind energy plant situation, for example flowing through fitful wind or wind eddies) or through external disturbance.The vibration of other origin also can increase the load in the power train, for example tower vibrations or because the vibration of the tooth engagement of driving mechanism under the wind energy plant situation.
, it produces other dynamic load during rotating during through tower at rotor blade.By block before the so-called tower (tower dam) (Turmvorstau) (under the rotor situation of facining the wind) or tower shadow (under the downwind rotor situation) in the wind energy plant power train, produces depend on lobe numbers, periodic bending moment load.In addition, if, in power train, produce static load so malposition occurring during the installation shaft between the parts of participating in.This malposition also can form and produce thus additional bending moment load and power along with the proper motion (for example creep in elastomeric support or sinking during being threaded) of time through equipment unit.
Especially the life-span of driving mechanism produces adverse influence to the parts of participating in for vibration and other additional load.The pulsating load that continues increases the wearing and tearing of relevant parts with static additional load and causes shorter replacing at interval, this means equipment and electrical network operator's economy and technical burden and minimizing equipment profit.Especially predict ever-increasing viewpoint from the use of wind energy plant greater coasting area in the near future, this aspect plays increasing effect, because the replacing of impaired parts is in this more difficulty that becomes.Therefore produce a kind of target, promptly reduce these load, so that improve the life-span of parts.
By the known a kind of method that is used for reducing in the vibration of the parts of wind energy facility of DE19930751A1; Wherein, In equipment, use the bearing of processing by elastomeric material; This bearing has the damping angle of 12o at least and has a kind of spring rigidity, and this spring rigidity is so selected, and makes the natural frequency of parts of vibration less than 50Hz.In this its defective be, the vibration of confirming for damping must use respectively known in advance elastomeric material and can not with variable vibration, for example suitable with the vibration amplitude of fluctuation.
Under this background, need improved solution, be used for reducing load, the especially torsional vibration of the power train of wind energy plant, and dynamic additional load, it can adapt to the load of these appearance neatly and guarantee to reduce better.Because the additional load of the static state that malposition produces should be reduced, so that whole drive unit is further unloaded.

As described, in the case, preferably on the different position of power train, through measuring the acceleration on the power train, and/or can survey vibration through velocity transducer.Under the velocity transducer situation, the derivative of speed is to confirming that acceleration can be significant.Can be on the position that relates to not just through corresponding position transducer detecting location yet.Advantageous particularly ground can use the observation element's (under parameter, especially moment of being occurred by the sensor Parameters Calculation by means of model) on parallel model (as for example open in EP0473914B1) and/or the regulation technology.Advantageously, also can in the scope of regulating, a kind of circuit adaptive (Streckenadaption) be set, it considers the characteristics and the deviation of theoretical model.The transmission numeral of the sensor signal of carrying and/or simulation can be used to regulate, visual management, control and/or switching.
Especially under emergency cut-off (electrical network unloading and/or minimizing load) situation, owing to the generator torque of suddenly removing in the wind energy plant causes great drive line vibrations.Therefore, advantageous particularly ground can use in the scope of emergency cut-off process according to device of the present invention, so that significantly reduce the vibration that occurs at this moment.
In addition, adjusting and/or control gear can comprise the wind field sensor that is used for activating in advance damped system, and they for example can produce the skew from middle position in damped system, so that increase the damping stroke thus.This wind field sensor advantageously is arranged in windward side.
What it should be understood that damped system thisly activates in advance, is using a plurality of sensors, acceleration for example, and power, rotating speed, rotation angle under the situation of position and/or torque transducer, also can or carry out individually or carry out in combination.
Advantageous particularly ground can use a plurality of final controlling element in scope of the present invention.Suitable final controlling element comprises electrodynamic, piezoelectricity, (cylinder formula, membrane type) and the pneumatic final controlling element of hydraulic pressure, they are for example also using electroactive polymer, and shape memory actuators or electrorheological fluid that learn or magnetorheological is realized down.
