摘要

柔性直流背靠背换流站换流站的阀厅电气设备布置是换流站布置设计的核心内容。阀厅布置尺寸主要由换流阀布置尺寸、换流阀交流侧进线、直流侧设备布置接线、空气净距、施工吊装空间、检修维护通道等因素决定。阀厅内换流阀塔的布置有同相上下桥臂相邻布置(AABBCC排列)和同极桥臂三相相邻布置(ABCABC排列)两种方式,换流阀塔的布置方式将直接影响阀厅内其他区域各电气设备的布置尺寸。工程设计时可根据空气净距取值,通过技术分析比较来优化阀厅布置设计。
        The electrical equipment layout of valve hall in VSC-HVDC back-to-back converter station is the core content in the layout design of converter station. The layout size of valve hall is mainly determined by the layout size of converter valve, AC side incoming line of converter valve, the electrical circuit connection of DC side equipment layout, air clearance, hoisting space in the process of construction, maintenance channel and other factors.There are two kinds of arrangement of converter tower in valve hall, including the adjacent arrangement of upper and lower bridge arms in the same phase(AABBCC arrangement) and the adjacent arrangement of three-phase bridge arms in the same pole(ABCABC arrangement). The arrangement of converter tower directly affect the layout size of electrical equipment in other areas of valve hall. In engineering design, the layout design of valve hall is optimized by comparing the values of air clearance in technical analysis.
