  • the present invention relates to the technical field of wind turbines.
  • the present invention relates to a method and to a machine load control system for controlling the operation of a wind turbine comprising a structural component, which during an operation of the wind turbine is exposed to a mechanical load.
  • Structural components of a wind turbine such as for instance the rotor blades and/or the tower are typically exposed to large dynamic mechanical loads in particular when the wind turbine is operated in turbulent wind conditions or in conditions of flow distortion, e.g. high wind shear.
  • the structural components and the corresponding supporting structures have to be designed in such a way that they are able to withstand all the mechanical loads that could occur at a specific site of erection.
  • This causes a lot of constructional expenses in particular for a wind turbine which is supposed to be erected at a site where extreme mechanical loads can be expected. Therefore, wind turbines are typically designed for certain wind classes, and prior to installing a wind turbine at a given site of erection, the wind conditions of the site have to be measured in a period of time to ensure that the wind turbine, which is supposed to be installed at that site, is not mechanically overloaded.
  • a wind turbine curtailment can comprise for instance stopping the turbine for predefined sectors or predefined wind directions, or running the wind turbine at a reduced power and speed in predefined sectors.

  • a total load value is determined based on the load value and the oblique
