Title:
INDIVIDUAL PITCH ADJUSTMENT METHOD AND ADJUSTMENT SYSTEM FOR WIND DRIVEN GENERATOR
Document Type and Number:
WIPO Patent Application WO/2024/002381
Kind Code:
A1
Abstract:
The present invention provides an individual pitch adjustment method and adjustment system for a wind driven generator. The adjustment method comprises: monitoring and obtaining a blade root load condition of each blade of a wind driven generator within a period of time, performing machine learning, determining an optimal pitch angle at each wind speed, and writing a correspondence between the blade root load and the optimal pitch angle into a control function; monitoring and obtaining the blade root load condition of each blade in real time, extracting rotating frequency information from the blade root load condition, and according to the rotating frequency information, determining whether the wind driven generator is currently in a full-power state; if the wind driven generator is currently in a non-full-power state, performing an individual pitch operation on the current blade according to a blade root load monitoring result of each blade and the control function; and if the wind driven generator is currently in the full-power state, according to the blade root load monitoring result of each blade, determining whether the blade root loads of all the blades are consistent, and if not, performing the individual pitch operation on the current blade in real time according to the blade root load monitoring result of the blade. Therefore, the purpose of increasing the generating capacity of the wind driven generator is achieved.
