Abstract

The present application provides a wind power generating set, its control method and system, and a computer-readable storage medium. The method includes: obtaining the top load of the tower; determining the unbalanced load of the main shaft of the wind power generating set according to the top load of the tower; determining the pitch angle of the blade according to the unbalanced load of the main shaft A compensation value; according to the pitch angle compensation value, determine a pitch angle control value; according to the pitch angle control value, control the pitching of the blades.

Description

technical field [0001] The present application relates to the field of wind turbines, and in particular, to a wind turbine, a control method and system thereof, and a computer-readable storage medium. Background technique [0002] It is known in the industry that with the development of wind power technology, wind turbines gradually tend to have large megawatts, high towers, large impellers, and lightweight designs. For large impeller units, blade root fatigue loads, hub unbalance loads and yaw unbalance loads increase significantly. In order to realize the lightweight design of the impeller and tower, the unit needs to adopt an independent pitch control strategy to reduce the fatigue load. [0003] The traditional independent pitch control is mainly by attaching a load sensor to the root of the wind turbine blade, and by measuring the load in the swing direction and the swing direction of the blade root, the unbalanced load on the rotating plane of the wind rotor is obtain...
