AI Technical Summary
In existing technologies, the uncertainty in wind speed measurement under high turbulence environments leads to inaccurate turbulence identification, increases the unbalanced load on the rotor surface and the risk of blade sweeping the tower, and affects the safety of the entire machine.
The characteristic quantities of the wind turbine itself, such as generator speed, rotor speed, and pitch angle, are used as the basis for turbulence identification. The inflection point location and change range are determined by moving average and numerical calculation methods to reduce the impact of uncertainty in wind speed measurement.
It improves the reliability of turbulence identification, reduces the impact of wind speed measurement errors on identification, and reduces the unbalanced load and tower sweep risk of wind turbines under high turbulence.
