Embodiment Construction
[0028] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0029] figure 1 It is a flowchart showing a pitch control method of a wind power generating set according to an embodiment of the present invention.
[0030] refer to figure 1 , in step S10, it is determined whether any blade is currently located within the angle range of the effective measurement headroom.
[0031] As an example, the angular range of the effective measurement headroom may be a predetermined angular range. For example, the angle range of the effective measurement headroom refers to the predetermined angle range near the azimuth angle of the impeller when the blade is perpendicular to the ground, in other words, refers to the angle range with the tower as the line of symmetry and radius and the central angle as the predetermined angle sector.
[0032] As an example, an azimuth sensor mounted on the hub may be used to determine whether...
