Abstract
A wind turbine control method for dampening vibrations of a transmission system, even in the presence of voltage dips and in any event that is susceptible to reducing active current generation capacity, is provided. First, for example, an initial torque or power instruction may be calculated based on a turbine operating state. Next, a torque or power adjustment term associated with dampening vibration modes of a turbine transmission system may be calculated. Then, a final torque or power instruction may be calculated by, for example, applying the adjustment term to the initial instruction. Finally, the final torque or power instruction may be transformed into a current instruction for controlling the wind turbine.
