摘要

特高压穿墙套管与阀厅、防火墙耦联体系的抗震性能直接决定换流站运行安全，现有研究多聚焦于单体抗震性能研究，缺乏耦联体系协同减震控制方案。本文建立穿墙套管-阀厅-防火墙耦联体系的等效理论模型，开展黏滞阻尼器、金属阻尼器和摩擦阻尼器的参数优化分析。结合ABAQUS有限元模型，选取7条地震波验证减震控制方案的有效性并对比不同阻尼器的减震控制效果。结果表明：所建立的等效理论模型与有限元模型结果吻合良好，可实现各类阻尼器核心参数的高效优化；三类阻尼器均能有效控制穿墙套管动力响应，其中摩擦阻尼器耗能效率与耦联体系震动频率无关，减震控制效果最优，可使穿墙套管应力响应峰值降低50％~60%，可使穿墙套管加速度放大系数降低30%~40%。

Abstract

The seismic performance of the coupled system comprising wall bushing

valve hall and firewall in converter stations is critical to operational safety. While existing research predominantly focuses on the seismic behavior of individual components

there is a notable lack of collaborative seismic mitigation strategies for the structural system as a whole. This paper establishes an equivalent theoretical model for the structural system integrating wall bushing

valve hall

and firewall

and conducts parametric optimization analyses for viscous dampers

metallic dampers

and friction dampers. Utilizing ABAQUS finite element models

seven seismic waves were selected to validate the effectiveness of the proposed seismic mitigation schemes and to compare the control efficacy of different damper types. The results indicate that the established equivalent theoretical model aligns well with the finite element analysis outcomes

enabling the rapid optimization of core parameters for various damper types. All three damper types effectively control the dynamic response of the wall bushing; notably

the energy dissipation efficiency of friction dampers is independent of the vibration frequency of the coupled system and presents the optimal seismic control performance

which can reduce the peak stress response of wall-through bushings by 50%-60% and lower the acceleration amplification factor by 30%-40%.
