摘　　要：换流站阀厅作为特高压电网中的主要建筑物,其抗震安全问题在高地震烈度地区尤为突出。该文从阀厅结构及其内部悬吊阀塔的抗震安全性出发,以阀厅及阀塔整体结构为研究对象,结合实际工程对高烈度地震区某±800 k V换流站的高端阀厅开展了结构选型研究。采用模态分析和非线性动力时程计算方法,分别对混合结构和全钢结构两种型式的阀厅进行了对比分析。综合考虑模态分析以及在不同地震波作用下的时程分析结果可知,全钢结构阀厅的抗震性能优于混合结构阀厅。因此对于高地震烈度区换流站高端阀厅,宜优先选用全钢结构型式。The valve hall of converter station is the main building in the ultra high voltage（UHV） power grid, and its seismic safety problem is especially prominent in high seismic intensity area. Based on the seismic safety of the valve hall structure and the internal suspension valve tower in it, taking the overall structure of the valve hall and the internal suspension valve tower as the research object, the structure selection of high voltage side valve hall of ±800 k V converter station in high seismic intensity area is studied in combination with an actual project. By using modal analysis and nonlinear dynamic time history analysis, two types of valve halls of hybrid structure and full-steel structure are compared and analyzed. Comparing the results of modal analysis and the time history analysis under different seismic waves, the seismic performance of the full-steel structure valve hall is found better than that of the hybrid structure valve hall. Therefore, the full-steel structure type should be selected for the high voltage side valve hall of converter station in high seismic intensity area.
