The embodiments of the present invention disclose a wind condition identification method, device, controller and wind power generating set. The method includes: acquiring the actual wind speed at a predetermined time; using the actual wind speed at the predetermined time as a starting point, drawing a standard extreme working gust curve of a target wind turbine within a predetermined period; determining the peak value and valley value of the standard extreme working wind gust curve; and valley value, determine the standard wind speed variation range of the standard extreme working gust curve; obtain the actual wind speed at the time corresponding to the peak and valley values respectively; determine the actual wind speed variation range according to the actual wind speed at the corresponding time of the peak value and valley value; according to the standard wind speed variation range And the actual wind speed change range, identify whether the wind condition in the predetermined period is a gust wind condition exceeding the standard. The wind condition identification method, device, controller and wind generator set according to the embodiments of the present invention can identify whether the wind condition in a predetermined period is a gust wind condition exceeding the standard.
Description
technical field [0001] The invention relates to the technical field of wind power generation, and in particular, to a wind condition identification method, device, controller and wind power generator set. Background technique [0002] In the wind turbine design standard, specific definitions are given for different wind conditions, which are used for control design and load calculation, and the design of wind turbines is also carried out according to the definitions in the standard. However, in an actual operating environment, the actual wind conditions will not exactly match those defined in the design criteria. Therefore, how to identify the wind conditions that do not meet the design standards is an urgent problem to be solved. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a wind condition identification method, device, controller, and wind generator set, which can identify whether the current wind condition is a gust wind condition exc...
