Compact offshore converter station installed by floating method
The invention provides a compact offshore converter station installed by a floating method. The compact offshore converter station comprises an upper chunk and a jacket; vertical channels are arranged at four corners of a plane of the upper chunk; a horizontal traffic channel is arranged on each of the south side, the north side and the middle of the upper chunk to form I-shaped corridor arrangement; an integral bottom frame is arranged at the bottom of the upper chunk and serves as a beam of a main power house; and the integral bottom frame serves as a structural transfer layer of the upper chunk and the jacket. The vertical space of a direct current chamber can be effectively utilized by adopting the combination of the arrangement of a single-side auxiliary power house and the interlayer arrangement of the direct current chamber, so that the arrangement form of each layer of traffic aisles can be simplified from a concentric-square-shaped arrangement form to an I-shaped arrangement form; and meanwhile, the horizontal position deviation between the overall gravity center of a structure and the geometric centroid is within an acceptable range, so the plane transverse size of the upper chunk of the offshore converter station can be reduced by about 15 meters compared with that of a traditional double-side auxiliary power house.
本发明提供一种用浮托法安装的紧凑式海上换流站，包括上部组块和导管架，所述上部组块的平面四角设置竖向通道，所述上部组块的南侧、北侧和中间位置各设一条水平交通道以形成工字形走廊布置，所述上部组块的底部设置整体式底部框架，所述整体式底部框架作为主厂房的梁，所述整体式底部框架作为上部组块和导管架的结构转换层。本发明采用单侧副厂房布置和直流室隔层布置的组合可以有效利用直流室的垂向空间，进而使得各层交通走道的布置形式可以由“回”字形简化为“工”字形，同时兼顾了结构整体重心与几何形心的水平位置偏差在可接受的范围内，使得海上换流站上部组块的平面横向尺寸较传统的双侧副厂房可减小15米左右。
