摘要(Abstract):
多端柔性直流换流站阀厅与常规换流站阀厅相比,在建筑跨度、建筑体量上差异较大。舟山多端柔性直流换流站阀厅在设计时针对海洋环境、极大风压以及材料运输等因素,采用横向框架、纵向排架钢结构,轻骨料钢筋混凝重屋盖和砖墙外维护体系,在安全可靠的前提下,较好地满足了建筑物抗风压、耐久性和立体施工等要求。研究成果填补了海岸环境下换流站阀厅建筑结构的设计空白,在国内外海岸换流站大跨度阀厅建设领域具有一定的参考价值。
Compared with conventional converter valve halls, the valve hall of multi-terminal flexible DC converter station is more different in building span and volume. The valve hall of Zhoushan flexible DC converter station is specially under island environment, high wind conditions and restricted by material transport conditions. Therefore, horizontal frame, longitudinal frame steel structure, lightweight aggregate steel-concrete roof and brick-wall external envelope are adopted to meet the requirement of wind pressure resistance, durability and stereoscopic construction with safety and reliability. The research fills the gap of converter station valve hall structure under the coastal environment, providing a reference for large-span valve hall construction in coastal converter stations in China.
