A rotation speed exclusion control method for a wind turbine generator system. The method comprises: when a power-limited operation instruction is received, determining a power value upper limit required by the instruction; determining that the required power value upper limit is in a power exclusion interval corresponding to a rotation speed exclusion interval; and when the required power value upper limit is in the power exclusion interval, setting the maximum allowable power value of a wind turbine generator system to be a lower boundary value of the power exclusion interval.

Wind turbine generator system, and rotation speed avoidance control method and apparatus therefor

A wind turbine generator system and a rotation speed avoidance control method therefor. The method comprises: according to statistical information of the rotation speed of a generator being in a rotation speed avoidance interval, identifying whether a wind turbine generator system repeatedly falls within the rotation speed avoidance interval; and when it is determined that the wind turbine generator system repeatedly falls within the rotation speed avoidance interval, adjusting a rotation speed avoidance control parameter of the wind turbine generator system according to the statistical information of the rotation speed being in the rotation speed avoidance interval. Correspondingly, further provided is a rotation speed avoidance control apparatus for a wind turbine generator system.

Methods and Apparatuses for rotational speed avoidance control of a wind turbine, and the wind turbine are provided. An exemplary method includes: identifying whether a wind turbine operates repeatedly traversing a rotational speed avoidance range, based on statistical information about a rotational speed of a generator being in the rotational speed avoidance range; and adjusting a parameter of a pitch control system and/or a parameter of an electromagnetic torque control of the wind turbine based on the statistical information about the rotational speed being in the rotational speed avoidance range, in response to determining that the wind turbine operates repeatedly traversing the rotational speed avoidance range.
