Abstract
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.关键词
