Abstract

The embodiment of the invention provides a rotating speed control method and device of a wind generating set, equipment and a medium. The method comprises the steps that the given rotating speed and the torque of the wind generating set are obtained; when the given rotating speed is equal to the lower limit value of a first rotating speed interval and the torque is larger than a first preset torque threshold value, the given rotating speed is adjusted to be increased, and the first rotating speed interval is the rotating speed interval corresponding to the resonant frequency range between the rotating frequency of the wind generating set and inherent components of the wind generating set; and under the condition that the given rotating speed is equal to the upper limit value of the first rotating speed interval and the torque is smaller than a second preset torque threshold value, the given rotating speed is adjusted to be reduced, and the actual rotating speed of the wind generating set is controlled through the adjusted given rotating speed. According to the embodiment of the invention, the safety of the wind generating set can be improved.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a rotational speed control method, device, equipment and medium of a wind power generating set. Background technique [0002] With the continuous development of wind power generation technology, wind turbines have now been widely used. [0003] At this stage, during the operation of the wind turbine, the actual speed of the wind turbine can be controlled by a given speed. For example, in the grid-connected process of the wind turbine, the actual speed of the wind turbine can be controlled to increase from the grid-connected speed to the rated speed through a given speed. [0004] However, there will be a rotational frequency during the rotation of the wind turbine. If the risk of resonance between the rotational frequency and the natural frequency of the structural components of the wind turbine is ignored in the process of using the given rotational speed to co...
