Abstract
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.

A method for rotational speed avoidance control of a wind turbine, comprising:
- 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.
An apparatus for rotational speed avoidance control of a wind turbine, comprising:
- a processor and a memory, wherein the memory stores a computer program, when executed by the processor, causes the processor to perform operations comprising:
- 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.
