中文摘要：

长跨度超离频电压(UHV ) 传播线有严肃的风神的颤动问题。控制这些颤动，我们在下列方面改进了精力平衡方法：风功率输入，导体自我抑制，并且更潮湿的驱散的功率。同时，我们造了电线 dampers 的一个理论机械模型并且导出精力驱散计算公式。这允许用电报浪费的颤动体力 dampers 能在精力平衡方法被考虑。然后，我们用 Matlab 基于改进精力平衡方法开发了一个计算机节目，并且在 P. R 分析了汉河长跨度工程的 UHV 长跨度地面电线。中国。结果证明电线 dampers 和 UHV 的 Stockbridge dampers 罐头还原剂颤动的联合长跨越传播线，它为设计工程的 UHV 的研究和建设提供一本参考书。

英文摘要：

Long span ultra-high voltage （UHV） transmission lines have serious aeolian vibration problems. To control these vibrations, we improved the energy balance method in the following aspects： the wind power input, the conductor self-damping, and the damper dissipated power. Meanwhile, we built a theoretical mechanical model of β wire dampers and derived energy dissipation calculation formulae. This permits the vibration energy dissipated by β wire dampers can be considered in the energy balance method. Then, we developed a computer program based on the improved energy balance method using Matlab, and analyzed UHV long span ground wires of the Han River long span project in P. R. China. The results show that the combination of β wire dampers and Stockbridge dampers can reduce vibration of UHV long span transmission lines, which provides a reference for research and construction of UHV engineering projects.
