Embodiment Construction
[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 As shown, the present invention proposes a torque control method for large-capacity wind turbines, including:
[0038] Step S1: establishing a generator torque fast following control equation and establishing a fast following control strategy based on the generator torque fast following control equation, the generator torque fast following control equation includes an estimated value of aerodynamic torque as a variable;
[0039] According to the torque transfer relationship between the wind turbine impeller and the generator, the rotor motion equation of the wind turbine can be expressed as:
[0040]
[0041] Among them, J sum is the per unit total moment of inertia of the wind turbine transmi...
