Title:
WIND TURBINE CONTROL METHOD, APPARATUS AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/123689
Kind Code:
A1
Abstract:
A wind turbine control method, and a control apparatus, control device and control system for executing the method, and a computer-readable storage medium. The method comprises: first determining the consumed life of a main shaft bearing on the basis of wind parameter data of a wind turbine, turbine operation data, and key load components of the main shaft bearing; then determining the remaining life of the main shaft bearing according to a designed life span and the consumed life of the main shaft bearing; determining control parameters of the wind turbine on the basis of the designed life span and the remaining life of the main shaft bearing, and the actually consumed time of the main shaft bearing; and controlling the rotational speed of the wind turbine on the basis of the control parameters of the wind turbine and preset parameters. According to the method, the influence of the service life of the main shaft bearing on the performance of the wind turbine is considered, thereby improving the control accuracy for the wind turbine.
