Definitions

  • Torsional drive train oscillations are a well-known phenomenon within the wind turbine community. These oscillations cause the speed of rotation of the drive train of a wind turbine to vary around a nominal value with a frequency of typical 1-2 Hz. Obviously torsional drive train oscillations need to be reduced to an absolute minimum in order to avoid unnecessary mechanical wear of the drive train components, the most critical drive train component being the wind turbine gearbox.
  • wind power facility should be understood very broad. Thus, the term wind power facility may cover a single, isolated wind turbine, or it may cover a group of wind turbines forming a wind power plant.
  • the method is applicable to both wind turbine facilities with full scale power converter and wind turbine facilities with doubly fed induction generators.
  • essentially all electrical power fluctuations may be absorbed in the power storing and/or power dissipating means so that essentially all electrical power fluctuations caused by drive train damping schemes are kept, and thereby dealt with, within a wind turbine facility.
  • essentially no electrical power fluctuations are provided to an associated power supply grid.
  • the amount of electrical power to be provided to the absorbing means including capacitive means such as capacitors, batteries, resistive dump loads and/or other suitable devices may be provided from the intermediate DC circuit of the power converter via a traditional chopper or a similar power regulating circuitry.
  • the power generator 3 here an induction generator, receives it magnetisation via the power converter in that the grid converter 7 draws AC power from the three winding transformer 4 and converts it to DC power.
  • the DC power is reconverted to AC power with an appropriate frequency by the rotor converter 6.
  • the rotor current of the AC power provided to the rotor magnetizes the induction generator whereby power can be drawn from the stator.
  • the rotor of the power generator is operatively connected to a set of rotatably mounted rotor blades 1 via an optional gearbox 2.
  • a low speed shaft (LSS) transfers captured wind energy to the gearbox.
  • a high speed shaft (HSS) transfers mechanical energy from the gearbox to the rotor of the power generator 3.
  • the next step is to determine whether the value of U DC is larger or smaller than the nominal value of U DC , i.e. the value of U DC during normal operation of the wind turbine. If the value of U DC exceeds the nominal value of U DC - for example during the positive half period - a DC chopper (reference numeral 10 in Fig. 1), including a resistive dump load and/or a storage element, is activated (step 13).
  • the DC chopper is, as depicted in Fig. 1, electrically connected to the intermediate DC circuit 8 whereby power in excess of a given power level can be dissipated and/or stored within the intermediate DC circuit 8.
