Embodiment

[0060] Please refer to Figure 1 to Figure 8 , the present embodiment provides a yaw control system for a wind power generating set. The yaw control system for a wind power generating set includes: a wind vane 100 , a connecting rod 200 , a pointer 300 , a reference plate 400 and a yaw assembly (not shown in the figure).

[0061] The connecting rod 200 is a straight rod. The connecting rod 200 runs through the top of the nacelle of the wind power generator and is rotatably matched with the nacelle of the wind power generator. The connecting rod 200 is arranged along the height direction of the wind power generator. In this embodiment, the top end of the connecting rod 200 is higher than the height of the blades of the wind power generating set. The top end of the connecting rod 200 is fixedly connected with the wind vane 100 , and the bottom end of the connecting rod 200 is fixedly connected with the pointer 300 .

[0062] The reference disk 400 is set in the nacelle of the w...

Abstract

The invention relates to the technical field of wind power generation, in particular to a wind generating set yaw control system which comprises a wind indicator, a connecting rod, a pointer, a reference disc and a yaw assembly. The connecting rod is arranged in the height direction of the wind driven generator, the top end of the connecting rod is fixedly connected with the wind indicator, and the bottom end of the connecting rod is fixedly connected with the pointer. The reference disc is arranged below the connecting rod and close to the pointer, and the disc face of the reference disc is perpendicular to the connecting rod. The disc surface of the reference disc is provided with a reference contact, and the point part of the pointer is provided with a first contact matched with the reference contact. And when the reference contact is in contact with the first contact, the yaw assembly is in a shutdown state. And when the reference contact is separated from the first contact, the yaw assembly is in a working state. The wind direction change can be sensitively sensed, yaw control can be carried out on the wind generating set in time, and regulation and control can be implemented according to the wind direction change.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a yaw control system of a wind power generating set. Background technique [0002] At present, in the process of wind power generation, the accuracy of yaw control is directly related to the efficiency of wind power generation. For large-scale wind power generation equipment, it is generally equipped with a precise yaw control system, but its cost is very high. For small and medium-sized wind power generation equipment, especially small wind power generation equipment, the supporting yaw control is much simpler. Therefore, the power generation capacity of small wind power generation equipment is always not fully utilized. [0003] In view of this, this application is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a yaw control system for a wind power generating set, which can sensitively perceive changes ...
