基于扭振激发机理的输电导线新型防舞模型研究

输电导线舞动对输电线路的安全运行构成重大的威胁，因此，防治舞动具有十分重大的经济意义和社会意义。论文通过对导线舞动的O.Nigol形成机理的传统防舞装置失谐摆的优缺点的分析，提出一种基于扭振激发机理的新型输电导线防舞动方法，建立了动力学模型，推导了模型参数的计算方法。该模型能够起到控制导线扭转自激振动的作用，可以在横向削弱舞动振幅。将该模型应用于某110kV实际线路，并运用仿真软件进行了该线路安装防舞模型的仿真分析，结果表明该模型对抑制导线舞动具有稳定与良好的效果。

A Study on Anti-galloping Model Based on Torsional Mechanism

The galloping is a critical threat to the security of power transmission lines. It will develop enormous social and economic value by researching the anti-galloping technology. The paper analyzes the characteristics of detuning pendulums and proposes a new type of anti-galloping model based on self-excited torsional oscillation mechanism. The model can contain galloping by inhibiting self-excited torsional oscillation. With this proposed model, simulation for one operational 110kV power transmission line is performed to demonstrate the rationality of the model and effect on anti-galloping.
