中文摘要: 针对降雨条件下特高压直流大跨越输电线路的电晕振动特性，以四川向家坝-上海奉贤特高压直流输电杨家厂大跨越为计算模型进行了分析。首先，研究了降雨条件下导线电晕振动产生的机理，并对振动导线和附着在其上的水滴进行了受力分析。然后以杨家厂大跨越为计算模型，建立了特高压直流线路大跨越线路的计算模型，基于有限元法计算了降雨条件下导线电晕振动的幅值。同时，在控制条件相同的情况下，分析了不同降雨强度时导线电晕振动的幅值。最后，基于对电晕振动现象的研究，提出了电晕振动的防治措施。

Abstract:Aiming at the corona vibration characteristics of UHV HVDC long span transmission lines under rainfall conditions,Yangjiayang long span of Xiangjiaba Shanghai UHVDC transmission line in Sichuan is taken as the calculation model.First,the mechanism of corona vibration of conductor under rainfall is studied,and the stress of the vibrating wire and the water droplets attached to it is analyzed.Then,taking Yangjiachang long span as the calculation model,the calculation model of UHVDC long span line is established,and the amplitude of conductor corona vibration under rainfall condition is calculated based on finite element method.Then,under the same control conditions,the amplitude of conductor corona vibration under different rainfall intensity is analyzed.Finally,based on the study of corona vibration phenomenon,some preventive measures of corona vibration are summarized.It can be concluded that the amplitude of corona vibration increases with the increase of rainfall intensity.The amplitude of corona vibration is 17.680×10-3 mm,which is about 2 times that of light rain.

keywords: high voltage transmission line corona vibration finite element method rainfall intensity
