According to the invention said aim is achieved by means of a method for controlling a wind energy system comprising a tower, a nacelle horizontally rotatably disposed on the tower, and a horizontal rotor rotatably disposed on the nacelle, wherein the distance to the rotor blades passing through is measured at at least two different measurement points by means of at least two non-contacting distance sensors disposed fixedly on the nacelle and symmetrically to the rotor axis, the measurement axes thereof running symmetrically to the rotor axis, and the measured distance signals or a difference between the signals is used as the guide parameter for the controlled or regulated adjustment of actuating parameters of the wind energy system. |
