摘　　要：地震频发地区的特高压换流站主设备在长期运行状态下的抗震性能关系到输电系统的安全和稳定。文中对特定特高压换流站主设备的抗震性能进行系统分类,提出主设备抗震性能运行状态下的评估方法,研究典型±800 kV特高压直流穿墙套管设备运维策略,评估特高压换流站主设备运行状态下的抗震性能。结果表明:换流站主设备可以按照不同类别采用差异化的抗震性能评估策略,安装减震措施的主设备需要进行力学性能测试以保证其结构的安全性;在运行状态下换流站主设备抗震性能评估方法包括有限元分析、现场测试、结构试验、综合对比分析等;运维策略可采用日常运维和专业运维策略,基于在线监测的方法可以更好的进行换流站整体运行状态的评估。The seismic performance of the main equipment of UHV(ultra-high voltage)converter station in seismic-prone area is related to safety and stability of the transmission system under long-term operation.In this paper,the seismic performance of the main equipment of a specific UHV converter station is systematically classified,the as-sessment method for the seismic performance of the main equipment under the operating condition is proposed.The operation and maintenance strategy of typical±800 kV UHV DC(direct current)wall bushing equipment is studied and the seismic performance assessment method of the main equipment of the UHV converter station under the oper-ating condition is assessed.The results show that the main equipment of the converter station can adopt differentiated seismic performance assessment strategies according to different categories,and the main equipment with damping measures needs subjecting to mechanical performance tests so to ensure the safety of its structure.The seismic perfor-mance assessment method of main equipment of the converter station under operating condition includes finite ele-ment analysis,on-site test,structure test,and comprehensive comparison and analysis.The operation and mainte-nance strategy can adopt the routine and professional operation and maintenance strategy.The method based on on-line monitoring is helpful in better assessing the overall operation condition of the converter station.
