摘要

针对高压输电线路在强台风气象下频繁出现风灾事故的现状

提出了系统进行塔-线耦联体力学模型和行为仿真研究的工程需求。文中以曾经出现严重风灾事故的广东某220 kV输电线路为研究对象

在ANSYS有限元开发环境下

建立了接近现场运行的三基塔两回线塔—线耦联体系有限元模型。在设计风速下

进行了0°、45°、60°、90°风向角时耦联模型静力响应分析

并将铁塔静力响应结果与拟静力计算结果进行对比。研究发现

考虑塔—线耦联影响后

铁塔位移较规范拟静力分析有所增大

增大幅度不超过3%

但单元最大轴向应力较拟静力分析增加显著。总体结论表明现行铁塔抗风设计方法存在一定局限性

在强台风区域中的具体应用有待进一步改进。

Abstract

Hurricane accident occurred frequently in high voltage transmission lines under strong typhoon

which proposed the demand of the simulation analysis of mechanical behavior of tower-line coupling system. Based on typical tower structure of a 220 kV transmission line in Guangdong

a finite element model of a multi-tower-line coupled system

including three towers and two span lines

is established using the development environment of international finite element method program ANSYS. Then

in the design wind speed

the static response analysis of the coupled model is carried out at 0

60 and 90 degree of wind angle

and the static response results of the middle transmission tower in the above coupled system are compared with the quasi-static analytical results of the solo tower. It is found that considering the effects of tower-line coupled

the displacement response of the tower increases substantially less than 3%

and the increment of axial compressive stress is more significant. The results show that the wind resistant design method of the current iron tower has certain limitations

which need to be further improved.
