摘要

输电线路舞动是在覆冰和大风条件下产生的一种低频、大幅的振动现象，严重危害电网的安全。本文针对500kV输电线路，利用数值模拟方法开展了覆冰分裂导线的舞动响应和控制研究。首先以新月形、扇形和D形覆冰分裂导线为例，研究了不同覆冰形状下分裂导线尾流效应和风攻角对导线气动特性的影响规律，根据得到的气动力系数计算气动载荷，进行了覆冰分裂导线舞动响应研究。在此基础上提出了新型防舞线间间隔棒和新型防舞相间间隔棒的舞动控制方法。通过与安装普通防舞线间间隔棒的档距中央导线舞动位移响应对比，安装新型防舞线间间隔棒可以使单相分裂导线舞动响应减小93.18%（垂直方向）、60.30%（水平方向）；而安装新型防舞相间间隔棒和新型防舞线间间隔棒可以使三相分裂导线舞动响应减小90.73%（垂直方向）、86.05%（水平方向），舞动控制效果显著，本文研究结果为覆冰分裂导线的舞动控制提供了一种新的方法。

Abstract

Transmission lines galloping is a low frequency, large amplitude vibration phenomenon caused by icing and strong wind, which seriously endanger affects the safety of the power grid. The galloping response and galloping control of 500 kV transmission line arewere studied by using numerical simulation method in this paper. Firstly, taking crescent-shaped, fan-shaped, and D-shaped ice covered split conductors as examples, the influence of wake effect and wind attack angle on the aerodynamic characteristics of the conductors under different ice covered shapes was studied. Based on the obtained aerodynamic coefficients, the aerodynamic load was calculated and the galloping response of the ice covered split conductors was studied. A new galloping control method for anti-galloping line spacing bars and phase spacing bars was proposed. By comparing the galloping displacement response of the central conductor in the span with the installation of ordinary inter line spacers, the results show that the installation of new anti-galloping inter line spacers can reduce the galloping response of single-phase split conductors by 93.18% (vertical direction) and 60.30% (horizontal direction); The installation of new anti-galloping phase and line spacing bars can reduce the galloping response of three-phase split conductors by 90.73% (vertical direction) and 86.05% (horizontal direction), the galloping control effect is significant. The research results of this paper provide a new method for the galloping control of ice covered split conductors.
