1. a kind of method that control has the wind turbine (1) of plane/sliding bearing (2) and bearing-lubricating device (7), describedMethod the following steps are included:

  • The bearing (2) is operated as hydrodynamic pressure bearing (HD) under normal operation;

    AndWhen the friction of the bearing (2) reaches threshold value, the bearing (2) is operated as hydrostatic bearing (HS), for streamThe operation of body static pressure, controls the temperature of the bearing (2);

    Wherein, the turbine and/or drivetrain components are adjusted by adjusting the pressure in the bearing-lubricating deviceThus rigidity and/or damping change the natural frequency and dynamic response of the turbine and/or drivetrain components, wherein instituteState bearing-lubricating device based on from for measure the pressure of the lubricant in the bearing (2) sensor (11) signal comeIt controls pressure unit (8).
