Abstract

The invention relates to the technical field of wind power generation, in particular to a tower drum assembly and a wind generating set. The tower drum assembly comprises a tower drum and a tuned mass damper, and the tuned mass damper comprises a suspension device, a mass block and a damper. The suspension device is fixed outside the tower drum; the suspension device is flexibly connected with the mass block and is used for suspending the mass block; and the two ends of the damper are fixedly connected with the mass block and the tower drum respectively. The wind generating set comprises the tower drum assembly. According to the tower drum assembly and the wind generating set, vortex-induced vibration is not prone to being generated, the design and machining difficulty is low, and the psychological stress of operation and maintenance personnel entering the tower drum can be reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a tower component and a wind power generating set. Background technique [0002] Wind turbines are generally installed in windy areas, and windy areas generally have complex terrain and frequent meteorological disasters. When the flow velocity of the airflow reaches a certain value, anti-symmetric Karman vortex streets appear on the back of the tower, which is prone to vortex excitation. Vibration causes fatigue damage to the structure of the tower itself and its fasteners, shortens its life, and ultimately endangers the safety of the entire project. Therefore, the tower is generally equipped with a tuned mass damper to alleviate vortex-induced vibration. [0003] The existing tuned mass dampers are all installed inside the tower, and the volume is limited by the inner space of the tower, so it is difficult to meet the vibration reduction requirements; the design of...
