Intermediate-frequency net-following type symmetrical bipolar offshore converter station
The invention provides an intermediate-frequency net-following type symmetrical bipolar offshore converter station, which comprises a first through layer and a second through layer, the first through layer comprises a first layer to a third layer, the through height is 20m, a polar line valve hall is arranged on the first through layer, a polar line direct current field is arranged adjacent to the polar line valve hall, and a 66kV GIS chamber and a metal loop direct current outgoing line are arranged on the same layer; the second through layer comprises 4-6 layers, the through height is 20 m, a neutral line valve hall is arranged on the second through layer, a neutral line direct current field is arranged adjacent to the neutral line valve hall, and a converter transformer chamber and a connection area are arranged on the same layer; and the design frequency of connecting the offshore converter station with the transformer, the converter valve and the bridge arm reactor adopts intermediate frequency. Optimized converter valves, bridge arm reactors, converter transformers and other key equipment are selected, space and the size of an upper module of the converter station are effectively saved, and therefore the problems that an offshore converter station platform is large in size and large in weight are solved, the steel structure purchasing and manufacturing cost is reduced, and higher engineering economy is achieved.
本发明提供一种中频跟网型对称双极海上换流站，包括通层一层、通层二层，通层一层包括分层1‑3层，通高高度为20m，通层一层布置有极线阀厅，极线阀厅相邻布置有极线直流场，同层布置的还有66kVGIS室以及金属回线直流出线；通层二层包括分层4‑6层，通高高度为20m，通层二层布置有中性线阀厅，中性线阀厅相邻布置有中性线直流场，同层布置的还有换流变压器室以及联接区；海上换流站联接变压器、换流阀、桥臂电抗器的设计频率采用中频频率。选用优化了的换流阀、桥臂电抗器、换流变压器等关键设备，有效节省空间以及换流站上部组块尺寸，从而解决海上换流站平台体积庞大、重量超大的问题，降低钢结构采购、制造成本，具有更高的工程经济性。
