Definitions

  • the invention relates to a method for reducing aerodynamic imbalances of wind turbines.
  • Wind turbines also referred to as wind power converters or wind turbines
  • the rotor is crucial for the mechanical efficiency of the wind turbine.
  • the present invention is a design of a known wind turbine with horizontal rotor axis, in particular with three-blade rotor.
  • an application of the present invention can also be made for designs with more rotor blades or even two leaves.
  • the rotor blades of modern wind turbines have aerodynamically carefully optimized wings, which not only maximize the efficiency and thus the energy yield, but at the same time minimize the noise.
  • the wings consist of perpendicular to the blade axis arranged profiles, which are each rotated by a twisting angle.
  • the invention relates to wind power plants which have an adjustment mechanism of the rotor blades about their respective longitudinal axis (pitch mechanism).
  • a rotor blade is constantly adjusted in operation by the plant control to an optimum pitch angle to ensure the necessary torque.
  • An important investigation, which is the basis for the correct setting in operation, is the measurement of the blade pitch.
  • the pitch angle of 0 ° is specified at standstill of the system control. The angle measured in this state will be referred to as the blade pitch. If this angle deviates from the manufacturer's specification, this is called an absolute error of the blade pitch angle. If the blade pitch angles of the individual rotor blades differ from one another, this is a relative error or a deviation in the synchronous position.
  • the state of the art is to set the rotor blades of a wind turbine as optimally as possible synchronously: By a correspondingly optimal synchronous position of the rotor blades of a wind turbine with respect to the zero degree Blateinstellwinkel the occurrence of an axial unbalance vibration is prevented. So far, rotor blades are adjusted by means of a marking scale in the flange area. In some cases, the setting of the rotor blades is also measured separately (usually photometrically or by means of a laser method). According to the guideline of Germanischer Lloyd (2010), the synchronicity of the three rotor blades of a wind turbine must be in the range of +/- 0.3 ° (total 0.6 °). It is believed that this accuracy is sufficient to prevent the occurrence of significant aerodynamic imbalances. However, this method is based on the assumption that the deviation of the zero grade blade angle adjustment is the dominant cause for aerodynamic imbalances.
  • the theoretical maximum of the achievable power is the Betz power factor. This value is 59.3%.
  • Wind turbines that meet the state of the art already achieve values of about 50%, so that the physically possible is largely exhausted.
  • the further optimization aims u.a. It is to largely eliminate inhomogeneities in circulation, ie mass-related or even aerodynamic imbalances of the rotor. It is therefore an effort of the experts to recognize, to take exclusively influence on the rotor, to bring the rotor blades in an optimal position and thus to achieve the vibration-free concentricity with maximum energy yield.
  • the low-vibration concentricity of the rotor requires both low aerodynamic imbalances, ie axial and radial vibrations, as well as low mass-related (usually radial) imbalances.
  • the mass imbalance is determined by the well-known, cross-disciplinary expertise by a series of measurements, consisting of a primitive course and a test run with mounted on the rotor, known in place and size test mass. The result is the size and location of a required balance weight.
  • Mass imbalances lead in particular to a radial oscillation, ie perpendicular to the rotor axis. Aerodynamic imbalances, caused by different pitch angles of the rotor blades, twisting errors, profile deviations, pitch errors, defective flow elements or damage to the blade surface, lead to axial, torsional but also to lateral (radial) excitations of the gondola tower vibrations. Mass or aerodynamic imbalances can lead to increased wear of all components of a wind turbine. In addition, incorrectly adjusted blade angles can ultimately lead to losses in the production of electrical energy. While the mass imbalance is therefore well manageable in practice, the aerodynamic imbalance, the cause of which are different contributions of the individual blades to the torque of the rotor, still causes problems and must be reduced by matching the individual powers of the rotor blades to each other.
  • Laser methods go have been described, for example, in the previously mentioned documents DE 10 2008 013 392 B4 and DE 100 32 314 C1. These methods are based on measuring the tracking of all three blades and then calculating the respective blade angles from the measured data.
  • the document US 2012 0 183 399 A1 proposes to carry out an initial measurement and then to adjust a rotor blade, which leads to a defined aerodynamic imbalance, and to determine the result obtained by the adjustment by means of a test measurement. Adjustment and test measurement are performed at least twice in order to be able to determine empirically from the results in a numerical method or according to a table of values, how an adjustment of the rotor blades must ultimately be carried out in order to reduce the aerodynamic imbalance. This process is inaccurate and at the same time complex, because to achieve an adequate accuracy in the reduction of the aerodynamic unbalance, a multiplicity of measuring cycles becomes necessary.
  • Object of the present invention is therefore to provide a method by which the absolute pitch adjustment and the synchronous position of the rotor blades of a wind turbine optimizes and at the same time vibrations in the radial and axial directions can be minimized.
  • the object is also to offer a particularly simple and quickly feasible method for reducing aerodynamic imbalance.

  • 1 P means the first order of a Order spectrum, related to the rotor speed.
  • An order analysis in the present case is to be understood as the analysis of the vibrations of rotating machinery.
  • the energy content of the vibration is not plotted against the frequency but above the order.
  • the order is a multiple of the speed. For example, a motor turns at 3000 revolutions per minute, which corresponds to a mains frequency of 50 hertz for a two-pole AC or three-phase motor.
  • the first order is then at 50 Hz, the second order at 100 Hz, the third at 150 Hz, etc.
