Research Review on Wind-induced Vibration Response of Pillar Equipment in Strong Wind Area

摘要:

大风地区支柱类设备大幅风振引起的隔离开关开合困难及疲劳损伤、断裂问题，是目前亟需解决的一种影响变电站（换流站）安全稳定运行的灾害形式。文中根据不同支柱类设备风振破坏特征对变电站风振引起的灾害事故进行了分类。按照支柱类设备仿真分析、支柱类设备设计施工两方面阐述了国内外研究的现状，对比了结构整体的分析研究，分析了从静力角度对变电站支柱类设备模型进行计算的不足之处，指出了目前对支柱类开关设备的风振响应动力分析与测试研究存在的问题；并对大风区支柱类设备大幅风振引起的隔离开关开合困难及疲劳损伤、断裂问题的未来研究方向进行了展望。

Abstract:

The problems of opening and closing difficulties in disconnectors, fatigue damage and fracture caused by largescale wind-induced vibration of pillar equipment in strong wind areas are a disaster form affecting the safe and stable operation of substation (converter station), which needs urgently to be solved. According to the wind-induced damage characteristics of different pillar equipment, the disaster accidents caused by wind-induced vibration in substation are classified. According to the simulation analysis of pillar equipment and the design and construction of pillar equipment, the current research situation at home and abroad is described, and the analysis and research of the whole structure are compared. The shortcomings in the calculation of pillar equipment model in substation are analyzed from the static point of view, and the existing problems in dynamic analysis and test research for windinduced vibration response of pillar equipment are pointed out. In addition, the future research directions for opening and closing difficulties in disconnectors, fatigue damage and fracture caused by large-scale windinduced vibration of pillar equipment in strong wind areas are prospected.
