根据阀厅结构的动力特性,推导了考虑悬吊阀塔晃动离心力的阀厅结构动力计算方程,建立了有限元模型,并将深圳某换流站阀厅结构模态分析结果与实测结果进行对比,验证了模型的正确性。在此基础上,对该换流站阀厅结构体系在不同峰值、不同场地和不同方向地震波作用下,分别进行了动力时程分析。根据分析结果对换流站阀厅结构体系的地震作用效应、塔索的拉力等问题进行了探讨,为换流站阀厅结构体系的抗震设计提供依据。
According to the dynamic characteristics of the structure of the valve hall, the dynamic calculation equation of the valve hall considering the centrifugal force of shaking the valve tower was deduced, and the finite element model was established. The modal analysis results of the hall structure of a converter station in Shenzhen were compared with the measured results , Verify the correctness of the model. On this basis, the dynamic time history analysis of valve hall structure system of the converter station under different peak values, different sites and different directions of seismic waves was carried out. Based on the analysis results, the seismic action effect of valve hall structure of converter station and the tension of tower cable are discussed, which provides the basis for the seismic design of valve hall structure of converter station.
