Title:
MAINTENANCE METHOD AND APPARATUS FOR WIND TURBINE, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/231247
Kind Code:
A1
Abstract:
A maintenance method and apparatus for a wind turbine, and a device. The method comprises: step S101, determining a fault of the wind turbine when the wind turbine enters a shutdown maintenance mode; step S102, determining the maintenance wind speed corresponding to the fault; and step S103, when the fault belongs to a first type of faults and the obtained real-time wind speed is smaller than or equal to the maintenance wind speed corresponding to the fault, adjusting one blade in the wind turbine to reach a preset azimuth, and locking an impeller of the wind turbine to perform maintenance of the wind turbine, wherein the first type of faults comprise a fault that the impeller needs to be locked for maintenance, and the preset azimuth comprises different integer multiples of 30°. The apparatus comprises a fault determination module (301), a maintenance wind speed determination module (302) and a processing module (303). The device comprises a memory (401), a processor (402), a communication interface (403) and a bus (404). According to the method and apparatus, and the device, the load of the wind turbine can be reduced, and the safety risk of maintenance personnel or the maintenance apparatus entering the wind turbine can be reduced.
