Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] like figure 1 Shown is a real-time flowchart of a control method for triggering a wind turbine pitch action command based on the average value, and the specific implementation process includes:
[0041] Step 1: Obtain the wind speed v at time t t and store records.
[0042] Step 2: Calculate the wind speed variance Var(v t ), the specific formula is:
[0043] v ‾ t = [ ∫ t - T t - 1 t v t dt ] / T t - 1
[0044] Var ...
