摘要

高压输电线路风致倒塔事故是近年来影响电力系统安全运行的重要因素。文中以南方电网某220 kV输电线路为背景

考虑铁塔和导、地线之间的耦联影响

运用ANSYS有限元分析软件

建立直线段塔线耦联三基塔两回线模型

对模型分别施加设计风速下的风载荷与时变风载荷

对比模型在两种情况下的静动力位移、应力响应数值差异

分析表明塔—线体系中铁塔的x、z向动力响应位移明显大于静力响应位移

铁塔部分主材轴应力与静力响应数值相比明显增大。研究结果可用于输电线路在风载荷作用下的可靠性分析。

Abstract

Wind-induced tower collapses of high voltage transmission line is an important factor affecting the safe operation of the power system in recent years. In this paper

based on typical tower structure of a 220 kV transmission line in Southern Power Grid

considering the tower-line coupling effect

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

constant load under design wind speed and time-varied load are respectively applied in the coupled system

and the static and dynamic responses of displacement and axial compressive stress in the above system are compared. The analysis shows that dynamic response values of the displacement and force of tower are significantly larger than that of the static response

which can be used to analyze the reliability of transmission line under wind loads.
