随着海上风电装机容量不断增大,采用高可靠性的双极拓扑方式可以降低单极停运时的电量损失,但其接线复杂、设备多、阀侧设备需承受直流偏置电压的特点,使其海上换流站的建设成本过高。文中研究了基于直流GIS设备的海上换流站换柔直变阀侧和直流场区域紧凑型布置方案,并与对称单极拓扑进行全寿命周期技术经济对比。研究结果表明,采用直流GIS可以显著优化对称双极海上换流站的尺寸重量及造价,大幅提升全寿命周期经济性平衡点的离岸距离,扩展对称双极在大容量深远海海上风电送出的应用场景。
As the installed capacity of offshore wind power keeps increasing
adopting a highly reliable bipolar topology can reduce the power loss during single pole shutdown. However
its complex wiring
multiple equipment
and DC bias voltage withstand requirement of valve side equipment make the construction cost much higher than mono-polar topology. This article studies a compact layout scheme for the valve side and DC yard of offshore converter stations based on DC GIS equipment
and compares full life cycle technology and economy index with a mono-polar topology. The research results indicate that the use of DC GIS can significantly optimize the size
weight
and cost of bipolar offshore converter stations
significantly increase the offshore distance of the economic balance point throughout the entire life cycle
and expand the application scenarios of bipolar topology in large-scale and far-reaching offshore wind power transmission.
