支撑式换流阀塔的抗地震设计

Anti seismic design of a supported converter valve tower

为应对柔性直流输电对阀塔结构越来越高的抗震要求,首先建立支撑式换流阀塔的有限元模型,进行抗震分析,同时搭建实物进行地震振动台试验。然后对仿真分析与地震台试验的结果进行分析对比,证明所设计的支撑式换流阀塔结构具有较强的抗震性能,研究成果对阀塔的设计、仿真及工程应用具有指导意义。

As the increasing higher seismic requirements of HVDC valve tower,this paper uses the FEM of the converter valve tower to analyze the seismic,designs the real seismic shaking table test. On the basis of analyzing and comparing the results of simulation and seismic test,it proves the seismic performance of the supported converter valve tower to be strong,provides the references for design,simulation and engineering application of valve tower.
