摘　　要：输电导线舞动对输电线路的安全运行构成重大的威胁。通过对基于导线舞动的O.Nigol机理的传统防舞装置失谐摆的特点分析,提出一种基于扭振激发机理的新型输电导线防舞动方法,建立动力学模型,推导了模型参数的计算方法。将该模型应用于某110 kV实际线路的防舞研究,运用仿真软件进行了该线路防舞的仿真分析,结果表明该装置对抑制导线舞动具有稳定与良好的效果。Galloping of power transmission lines is a dangerous phenomenon that seriously threatens the security of power systems.Through an analysis of the characteristics of detuning pendulums of the O.Nigol mechanism-based traditional anti-galloping devices,a torsional mechanism-based new anti-galloping method is proposed to establish a dynamic model,and a method is developed for calculating the model parameters.With this model,a simulation software is used to simulate the anti-galloping of a 110 kV transmission line project.The simulation result demonstrates that this model has a very stable and good capability in anti-galloping.
