In view of this situation, the strategy of wind turbines in the prior art is to stop directly, but direct shutdown will not only waste the energy contained in the small wind, but also easily lead to frequent start and stop of the unit when the wind speed fluctuates repeatedly, causing the wind turbine to consume more energy. Power increases while lifetime decreases

The embodiment of the invention discloses an operation control method and device of a wind power generating set, and a storage medium. The method includes: detecting the rotational speed of the wind generating set; if the rotating speed is less than the first preset rotating speed and lasts for the first preset time, controlling the wind generating set to enter the small wind power generation state; the small wind power generation state is configured as, the wind power generating set changes The target speed of the propeller control system is the rated speed of the wind turbine, and the minimum speed of the torque control system of the wind turbine is lowered from the initial minimum speed to the second preset speed, and the second preset speed is in resonance with the tower of the wind turbine The frequency corresponds to a speed range; wherein, the first preset speed is lower than the initial minimum speed, and the second preset speed is lower than the first preset speed. By adopting the technical solutions in the embodiments of the present invention, the wind power generating set can make full use of the energy contained in the small wind, and avoid the problem of frequent start and stop of the generating set caused by repeated fluctuations in wind speed.
Description
technical field [0001] The present invention relates to the technical field of wind power generation, and in particular, to a method and device for controlling the operation of a wind power generator set, and a storage medium. Background technique [0002] figure 1 It is a schematic flow chart of the original operation control method of the wind turbine. [0003] like figure 1 As shown, the original operation process of the wind turbine is: the cycle of standby state-starting state-accelerating state-generating state-stopping state. Wherein, the standby state is configured as: the wind turbine is at rest, and the pitch angle is around 90 degrees. The start-up state is configured as: performing a propeller-opening operation on the wind turbine, and the pitch angle is changed from 90 degrees to 0 degrees. The acceleration state is configured to increase the rotational speed of the wind turbine until the grid-connected rotational speed is reached. The power generation stat...
