DAMPER UNIT FOR A TOWER STRUCTURE

The present invention relates to a damper unit for damping oscillations of a tower structure when secured thereto, the damper unit comprising a damper unit structure adapted for attachment to the tower structure, a pendulum structure, a suspension arrangement for suspending the pendulum structure from the damper unit structure such that the pendulum structure is allowed to displace from a neutralposition for the pendulum structure, the suspension arrangement comprising one or more wires for suspending the pendulum structure, a sensor adapted for measuring oscillations of the tower structure,and tuning means configured for adjusting the natural frequency of the suspended pendulum structure in response to measured oscillations of the tower structure. The present invention further relates to an associated method. 本发明涉及一种阻尼器单元，该阻尼器单元在被固定至塔结构时对该塔结构的振动进行阻尼，该阻尼器单元包括：适于附接至塔结构的阻尼器单元结构；摆锤结构；悬挂装置，该悬挂装置从阻尼器单元结构悬挂摆锤结构，使得允许该摆锤结构从摆锤结构的中间位置移位，该悬挂装置包括悬挂摆锤结构的一根或更多根线材；适于对塔结构的振动进行测量的传感器；以及调谐装置，该调谐装置被配置成响应于所测量的塔结构的振动来对所悬挂的摆锤结构的固有
