中文摘要: 防舞动动力减振器可通过改变线路结构参数减轻或抑制输电线路舞动,降低舞动对电网造成的机械与电气方面的危害。目前,缺乏针对防舞动动力减振器的构型方法,导致其构型稀少,限制了防舞动动力减振器的实际应用。本课题拟基于输电线路舞动机理机理,明确动力减振器的防舞机制,并提出防舞用动力减振器构型的性能指标。在分析动力减振器构型与被动机器人构型的基础上,将防舞用动力减振器作为被动机器人机构进行研究,并针对防舞动动力减振器的构型性能指标,研究防舞用动力减振器型综合方法,建立动力减振器的构型库,丰富防舞用动力减振器的选型空间。该研究对促进防舞用动力减振器的实际应用、提高电网安全稳定运行具有重要的理论意义与实际价值。

英文摘要: Through changing the structural parameters of transmissoin lines, the galloping of transmission lines can be controlled, leading to the decreasing of influence in the mechanical and electrical aspects. Curently, it still lacks of type synthesis methods for dynamic vibration dampers, which is the main reason for the few types of dynamic vibratoin dampers for the anti-galloping issues and the less applications. This research aims to show the mechanisms of dynamic vibration dampers for anti-galloping and propose the performance index for the types of the related dampers, based on the galloping mechanisms of transmission lines. Via comparing the types of dynamic vibration dampers and passive manipulators, we will regard the corresponding dampers as passive manipulators. Moreover, the type synthesis method will be proposed and the types gallary will be achieved. This research is helpful to the application of dynamic vibration dampers for the anti-galloping issue, and meaningful for the safety of the power grid.
