Closed compact offshore converter station
The invention provides a closed compact offshore converter station, which is characterized in that a valve hall in an upper module of the offshore converter station is arranged in an upper-layer space, a cooling and heating and ventilation equipment room is arranged in a lower-layer space, and a direct-current field is arranged in a lower-layer space; inclined struts can be arranged at room partition walls of lower-layer spaces of valve halls in a cooling and heating and ventilation equipment room and a direct-current field to effectively support the ground of the valve halls. After the valve hall of the offshore converter station is arranged in the upper space of the upper module, the wire inlet GIS chamber in the prior art can move downwards to the second layer, and the direct current field can move downwards to the first layer. Therefore, the incoming submarine cable can reach the incoming GIS chamber only through one cable layer, and the direct current outgoing submarine cable can directly reach a direct current field of one layer, thereby greatly reducing the lifting height and the use amount of the submarine cable, and effectively solving the problems in the prior art that the difficulty of submarine cable lifting construction is high, and the overall arrangement is affected by the overlarge size of a cable room.
本发明提供一种封闭式紧凑型海上换流站，将海上换流站上部组块中的阀厅布置在上层空间，冷却与暖通设备间、直流场布置在下层空间，由于冷却与暖通设备间、直流场的开间小，冷却与暖通设备间、直流场等四层、五层内的阀厅下层空间的房间隔墙处可以设置斜撑，有效支撑阀厅地面；将海上换流站的阀厅置于上部组块的上层空间后，现有技术方案中的进线GIS室便可下移至第二层，直流场便可下移至第一层。由此，进线海缆仅需经过一层电缆层即可到达进线GIS室，直流出线海缆可直接到达一层的直流场，大幅减小了海缆的提升高度与自身用量，有效解决了现有技术中海缆提升施工的难度高与电缆房间尺度过大影响总体布置的问题。
